This document is an updated list of the supplements/drugs that I take daily, as well as notes on some other interesting substances. It contains information on exactly what I take, how much of it, how much it costs, and some information on the substance which should roughly explain my reasons for taking it.
The first list contains supplements I take daily, with the second list containing supplements that I do not take daily but that nonetheless seem interesting, and the third list contains supplements that are interesting, but that seem less suitable for safe human consumption or speculation.
The focus of my supplementation is to find substances that are both very safe and also have a notable probability of improving health, lifespan, well-being, or productivity, with the ultimate goal being to significantly slow aging, even if it’s difficult to do at this time. I don’t take many nootropics as I don’t think there’s much room for intelligence improvements just from ingesting simple compounds (evolution has already put quite a bit of time into making us smart), with the exception of treating some deficiency or other issue, or improving productivity/concentration, which definitely possible (see: caffeine, modafinil, adderall, many others), but distinct from intelligence.
This post is not an attempt to convince anyone of something specific or to suggest anything specific, but I have decided to publish it publicly in order to better keep myself accountable for my reasoning, receive potential feedback, and to otherwise share some potentially useful short summaries of information. Concordantly, I’m not a doctor and this post contains no medical advice or suggestions. Which supplements, if any, one should take, is a very personal matter, as it is dependent upon many unique traits such as one’s age, diet, lifestyle, genes, risk preference, finances, and more.
Notes on supplements
Although there are a lot of supplements that would be beneficial to many people, caution must be exercised both with research and purchasing. Supplements in the United States have very little regulation, with some sellers having poor quality control, fraudulent research, marketing, claims, and poor ingredient composition and sourcing. The supplement industry is worth billions of dollars and has many bad actors incentivized by profit over truth, so time and care must be exercised in order to find out what works best for you personally. Certainly, research can be found promising positive effects from thousands of various substances – but taking all of them would be impractical, expensive, and downright harmful.
Concordantly, one of the strongest criteria I look for in most supplements is safety, which many times (not always!) comes alongside popularity. As many supplements offer marginal benefits at best, it would be irrational to purchase and consume them if they had a good chance of causing harm, as this would easily cause them to fail a basic cost/benefit or risk/reward analysis.
Ideally one should attempt to find quantitative measures to objectively evaluate if a substance is really helping them in the desired manner. In some cases this is both easy and cheap to do, for example with Vitamin D supplementation, which costs only a few cents a day, does not need to be compared to a placebo, and can be tested for in your blood for as little as $30. In other cases, proper testing is difficult or impossible and may require significant effort and time for very little benefit. Keeping one’s lifestyle, diet, and other factors a perfect experimental constant is certainly difficult, as is performing blind experiments on yourself, collecting and analyzing data, and finding the proper quantitative desideratum to test yourself on to begin with; testing if something specific has definitively made you slightly smarter, happier, healthier, more productive, or extended your lifespan, is certainly difficult if not occasionally impossible to do in a scientifically rigorous manner with a sample size of one.
Additionally, which supplements benefit an individual is a very personal matter. Vegans may want to take some supplements that are found in meat. Carnivores may want to take some supplements that are found in plants. Supplements that may benefit the elderly or those with common conditions such as hypercholesterolemia or diabetes often seem to be much less useful for otherwise healthy individuals. Indeed, for individuals that have many health conditions including the elderly, there’s significantly more that can be gained from supplementation, as there are many more problems that can be improved upon (although there are also be more risks as well). Supplements will effect someone differently depending on their weight, age, genetics, health, diet, and many other factors. As such, it’s a bad idea to copy any individual’s routines completely, even if it’s a lot of work to do your own planning, research, and testing. It is also worth mentioning that the word ‘supplement’ is used here as a relatively generic word, simply meaning that the substance is only regulated as a food within the United States and thus requires no prescription (unless otherwise mentioned), but also offers few guarantees in terms of efficacy or consistency.
Supplements I take daily
The following list contains supplements that I’m currently taking daily.
Name: Vitamin D3
Dosage: 3,000+ IU (75+ µg)
Information: Vitamin D3 [Examine, webmd, Wikipedia] (colecalciferol) is a vitamin made by the skin when exposed to sunlight. It’s a common deficiency and is very cheap to fix. The benefits of supplementation are generally found to be minor (it’s still a bit controversial if supplementation is beneficial at all, although I lean towards yes personally), but as I was notably deficient and it’s one of the cheapest supplements, it’s an easy choice for me. I take vitamin D earlier in the day without a meal, contrary to most other supplements.
Name: Fish Oil
Cost/day: $0.10 (1g)
Information: Fish oil [Examine, webmd, Wikipedia] (omega-3 EPA+DHA) is another common and cheap supplement. Although many studies find minor or sometimes no benefits, many others find a large amount of diverse improvements, even if they are minor. It’s likely that the ratio of omega-6/omega-3 you consume is important, with most people consuming far too much omega-6 (which won’t hurt to reduce regardless) and not enough omega-3, so dosing of fish oil should be based on your diet, which is easily more than an order of magnitude more important to begin with.
Cost/day: $0.02 (1g)
Information: Garlic [Examine, webmd, Wikipedia] is another popular and cheap supplement. There’s good evidence that it improves lipid profiles, may help with some cancer risks, and may have other very minor benefits (may activate AMPK too?). The most desirable compound in garlic is allicin, which is diluted in garlic that is microwaved, boiled, or aged. Dosage should be based on which type of garlic is being consumed. As many people enjoy the taste of garlic, it’s a good candidate to include in meals as well.
Name: Olive Leaf Extract
Information: Olive Leaf Extract [Examine, Wikipedia] is a cheap and easy way to hopefully mimic the benefits of olive oil, as the leaves of the olive tree contain good amounts of relevant olive phenols such as oleuropein. It may still be better to consume olive oil instead, which is still a great thing to add to meals, but with such a low cost, this seems worth inclusion to me.
Name: Magnesium Citrate
Information: Magnesium [Examine, webmd, Wikipedia, Gwern] deficiencies are moderately common (up to 45-60%) and easily fixed. Fixing a magnesium deficiency is cheap and seems to offer quite a few minor general benefits, and also sleep and anxiety improvements for some. Depending on your diet, supplementation may be unnecessary. Magnesium comes in a lot of different forms so close attention is needed when purchasing. I stick to citrate as it makes dosing easier, has good bio-availability, and is unlikely to cause digestion issues. The above Gwern link is a great resource on Magnesium as well.
Name: Vitamin K2 MK-7
Information: Vitamin K [Examine, webmd, Wikipedia], like most vitamins, is primarily beneficial for those deficient in it, so it is best to examine your diet thoroughly and/or be tested. There are several forms of vitamin K, and also several forms of vitamin K2. Vitamin K2 MK-7 seems to be one of the best forms to take in general, although K1 has decent evidence in favor of it as well, depending on one’s circumstances. I’ve temporarily discontinued this supplement after running out of it, awaiting more analysis and research.
Name: Glucosamine Sulfate
Information: Glucosamine [Examine, webmd, Wikipedia] is an amino sugar derived from shellfish that is commonly taken by the elderly to improve joint functionality and reduce pain. Glucosamine extends the lifespan of some mammals in studies, potentially in ways that are evolutionarily conserved, activating AMPK and therefore having slight similarity with metformin. Glucosamine may also induce autophagy via an mTOR-independent pathway, which may be the mechanism of action for its effects on lifespan. Due to its popularity as a supplement we can be relatively sure of its safety as well. Chondroiton is commonly included with glucosamine supplements, which appears very uninteresting for my own purposes, so I look for pure d-glucosamine/glucosamine sulfate, which is generally cheap.
Information: Glycine [Examine, webmd, Wikipedia] is an amino acid that is often supplemented to improve sleep. Better sleep is formidable by itself, but some studies find that it increases lifespan in organisms via methods that may be evolutionarily conserved. Although glycine is present in some foods and is also synthesized by your body, it may be the case that glycine deficiencies are technically common in humans, as the amount that is able to readily be synthesized in-vivo is sub-optimal. This may be relatively asymptomatic from an individual perspective and only manifest itself via a slight probabilistic decrease in healthspan/lifespan, although users often notice quite a few improvements besides just better sleep. Glycine may improve insulin sensitivity and other similar metrics. There may be some longevity benefits of a diet low in methionine (meat, fish, eggs, etc) as well, which may be related to one’s effective glycine/methionine ratio. I still consume a lot of methionine from common sources such as chicken breast, so this is another potential way in which glycine could be beneficial. Glycine appears to be very safe, even in larger doses, and is relatively cheap, more so as a powder, as is the case of most substances.
I take glycine in powder form, either adding it to drinks or meals, but for smaller doses of 1-2g, it might be easier to take gelatin capsules of 1g each. I’m still playing around with my glycine dosage to try to optimize it, the current dosage may appear a bit high to some, which was arrived at from a combination of the papers linked above (and linked to by those links), as well as some reasoning about my diet (high in methionine) and lifestyle. Unfortunately even with a blood plasma test of amino acid concentrations, it’s difficult to know if this is the optimal dose for human longevity, or if it is even helpful at all to begin with, but the cost/benefit analysis here still seems to lean heavily into the green. As a simple and common amino acid, it seems pretty difficult to hurt yourself with glycine, so even taking 10-20g a day shouldn’t be harmful.
Information: Bacopa [Examine, webmd, Wikipedia] is an herb that seems to offer reliable but likely very minor improvements to some areas of memory and general cognition. Effects are likely difficult to notice without rigorous placebo-controlled self-testing, but it is relatively safe and cheap regardless. Digestive side-effects aren’t uncommon, as is the case with many herbal supplements. In the future I’d like to replace my bacopa with a placebo and attempt to look for differences in quantitative cognitive performance metrics such as my anki recollection, but performing this experiment well is difficult, both because the effect is very minor and because a proper experiment with n=1 is very difficult.
Information: Ashwagandha [Examine, webmd, Wikipedia] is an herb that offers potential anxiety and lipid profile improvements. Some users report that it reduces anxiety and stress significantly, with some studies showing up to a 28% reductions in cortisol (in subjects with elevated levels). Lipid improvements can also be notable, with some studies showing a 10% reduction of total cholesterol, even in healthy subjects. As an uncommon herbal supplement, digestive side effects are a notable probability. Ashwagandha is likely worth trying if you feel that you have untreated anxiety.
Information: Astaxanthin [Wikipedia, webmd, Examine] is a carotenoid generally derived from seafood. It’s suggested that it exhibits photoprotective, antioxidant, and anti-inflammatory effects, and has improved triglyceride and cholesterol levels as well as oxidative stress in humans, although not in completely healthy individuals.
Astaxanthin has increased the life span of C. elegans by 16-30%, with the authors stating “These results suggest that AX protects the cell organelle mitochondria and nucleus of the nematode, resulting in a lifespan extension via an Ins/IGF-1 signaling pathway during normal aging, at least in part”. While this is certainly interesting, expecting such a lifespan increase in humans is far too optimistic from this case alone.
However, Astaxanthin may be able to activate FOXO3 in humans, an important gene for human longevity which is present in many centenarians. Some other well-known natural compounds such as resveratrol and curcumin also interface with FoxOs, although these substances are still relatively speculative as far as anti-aging effects in humans go, even if they do have many strong supporters.
There’s some other interesting potential effects of astaxanthin, with some papers showing that it increases neural stem cell proliferation and may be useful to help curb dementia, and other papers showing that it can improve skin health and appearance, leading it to become an ingredient in some cosmetics.
Astaxanthin appears to be very safe in humans and is a relatively popular dietary supplement, with a market estimated at over $500M USD annually, although the majority of this supply is used as a component in animal feed and cosmetics.
Information: Berberine (Examine, webmd, Wikipedia] is an extract from various plants. It appears to be a pretty strong natural mimetic of metformin, a popular drug for diabetes with many alluring potential anti-aging properties. It often improves lipid profiles and blood glucose, and thus may have many of the long-term benefits that metformin may have. Concordantly, the possibility for digestive side-effects is relatively high, and it’s sometimes taken several times a day in smaller doses as a result. Examine suggestions that it also inhibits enzymes such as CYP2D6 to some extent, which could lead to undesirable interactions with some drugs. It’s likely better to be on metformin than berberine, as drugs are kept to a significantly higher regulatory standard than supplements are and we have much more data on users of metformin. Update: my berberine usage has been indefinitely discontinued and replaced with metformin.
Cost/day: $0.10 (much higher If drinks are considered)
Information: Caffeine [Examine, webmd, Wikipedia] is something you likely don’t need an introduction to. I try to keep my dosage relatively low to avoid issues with tolerance, using a combination of coffee, tea, or caffeine pills, depending on the amount desired and my mood. When taking 100mg or more of caffeine, I generally have 100mg of L-theanine as well.
Dosage: 0-200mg, generally 100mg if taken
Information: L-theanine [Examine, webmd, Wikipedia] is an amino acid that is present in tea leaves which is often combined with caffeine for supposedly synergistic effects on cognition and mood, improving the upsides of caffeine while helping to ameliorate some of the potential downsides. I generally only take it if I’m having more caffeine than average on a given day, since I keep my caffeine intake pretty low.
Information: Melatonin [Examine, webmd, Wikipedia, Gwern] is a hormone secreted by the pineal gland with an important role in regulating your sleep cycle. Melatonin production can be suppressed in many individuals that are otherwise healthy, for example by exposure to blue light from computer screens before bed (which solutions like the program f.lux and blue-light blocking glasses attempt to solve). The generally accepted benefits of melatonin are a reduction in the time to fall asleep, although some individuals claim that it reduces their need for sleep as well (often by 15-60 minutes). For those with sleep conditions such as insomnia or jet lag (or just being older in many cases), melatonin can be a much greater aid in improving sleep and quality of life.
One meta-analysis (K=10, N=653), found melatonin supplementation may have helped significantly reduce some instances of cancer mortality (R = 0.66 after 1yr). Some studies also find improvements in gastroprotection, healing and reducing the rate of stomach ulcers.
Melatonin has increased the lifespan of some mice by 18%, primarily given as a supplement later in life in an attempt to give older mice more effective pineal gland functionality (directly giving older mice the pineal glands of younger mice was also performed, which also was very beneficial). Melatonin levels similarly decline with age in humans (as most important things do), and supplementation may be increasingly beneficial as one ages.
The proper dose of melatonin to take varies between individuals and many melatonin pills for sale are dosed too high (5-10mg), so approximate self-experimentation can be used such as starting with 0.5mg and increasing your dosage until benefits are noticed. The above link to Gwern’s website on Melatonin points to a good in-depth analysis that is worth reading as well.
I don’t always take melatonin, but it’s great to be aware of and have.
Information: Metformin [webmd, Wikipedia] is a prescription drug for diabetes and is one of the most popular drugs taken by those interested in longevity, often taken for this purpose by individuals without diabetes. Metformin is said to mimic some of the potential benefits of caloric restriction. It increases the lifespan of mice, increasing AMPK activity and antioxidant protection, resulting in reductions in both oxidative damage accumulation and chronic inflammation. Lifespans of other organisms such as silkworms and nematodes are also increased. There exists a vast literature on metformin with respect to its mechanisms of improving longevity apart from just this; it’s currently the most popular drug taken to combat aging.
Due to the prevalence of diabetes, metformin has over 80 million users (the vast majority taking it for diabetes), which gives us wonderful data on its safety, with its side effects rarely including anything besides minor gastrointestinal issues. Metformin is also cheap, costing only $5-$25 a month in the United States. For the above reasons and many others, metformin appears to be one of the best candidates for an anti-aging drug, leading it to become one of the only drugs making clinical progress in this area with trials such as TAME (Targeting Aging with Metformin). Metformin deserves a larger write-up than I’ve given it here, so you’re encouraged to perform your own research on it (just as you should for anything written about on this page).
This list changes as I encounter new evidence, test new supplements, or change other aspects of myself such as my diet or lifestyle, but I hope to keep it updated, even if only for myself. I’m constantly looking for substances that have a good probability of doing a much better job at enhancing longevity, but it’s very hard to find and test them in a safe way – it’s unlikely many supplements such as simple vitamins or herbs are truly going to increase out lifespan notably. The next section has more information about some substances which are more interesting, but that I’m currently not taking.
Currently I spend around $1-2 a day on supplements. As my average food expenses can easily exceed $10 per day, a 10-20% increase in this is not too bad of a price for me to pay, even if the benefits are mostly minor. Healthcare costs are very high, so anything that may lower them, even if decades down the line, can turn out to be very cost-effective. Regardless, spending money on improving my own health seems to be the best possible use of money – it is the least fungible thing I can spend on. This reasoning applies to improving diet and exercise as well, which generally offer much greater returns than most supplementation.
I try to keep my supplement stack very minimal and would rather dedicate research time and effort towards substances that might have significant effects on aging such as metformin and rapamycin, rather than substances that are often very difficult to determine any effects of, such as the large amount of amino acids or uncommon vitamin forms that can be taken. Keeping the amounts of supplements I take to a minimum offers much more than a financial benefit – it reduces the probability I will cause damage to my liver over time (which users of many supplements, or anything risky, should get tested for), and reduces the probability there will be any type of drug interactions caused by anything I take, for example by some substances inhibiting or inducing enzymes that then cause other substances to increase or decrease in efficacy (see CYP3A4 and CYP2D6 for some good examples).
Additional supplements I do not currently take
This section contains a list of supplements that I think might be worth taking, but that I currently don’t use. Substances in this section seem to be relatively safe, and I’m generally only taking them because I have more doubts about their usefulness to me specifically.
Aspirin [Wikipedia] is used for more than just treating temporary pain or fevers. As an NSAID, it reduces both acute and long-term inflammation, and may also affect oxidant production, cytokine responses, and block glycooxidation reactions. Consuming a low dose of aspirin daily appears to lower the risk of CVD in higher-risk groups (generally older individuals with a relevant medical history), although appears to have little effect in otherwise healthy individuals. The risks of a few cancers may be lowered slightly by long-term continual use of aspirin, although this is generally a minor effect, and doesn’t seem to be the case for all types of cancer. Some organizations suggest daily aspirin use in small doses for those in certain risk groups, generally those that have already experienced a heart attack or stroke.
Among aspirin’s more common adverse effects is an increased risk of gastrointestinal bleeding, which is one of the reasons it’s not suggested by most organizations for otherwise healthy individuals with low CVD risk. Aspirin has increased the average lifespan (although not the maximum lifespan) of mice in some studies, but this is unlikely to be the case in humans unless significantly more needs to be taken, which would increase the probability of adverse effects notably.
To summarize, it’s very likely that continual aspirin usage reduces the risk of some types of cancer and moderately likely that it can reduce the risk of CVD in some higher-risk groups. Although side-effects are negligible for most individuals, it is difficult to tell if aspirin is worth taking for healthy and young individuals. It’s likely much more beneficial for the elderly or middle-aged, as they’re at a much higher risk of cancers as well as CVD. As a result of this, I don’t take aspirin regularly.
Cocoa [Examine, webmd, Wikipedia] is well-known as a major component of chocolate. Although the sugar added to most modern chocolate definitely does not benefit one’s health, cocoa itself has many bioactive substances with potential benefits. Among the most notable is (-)-epicatechin, which can offer improvements in blood flow and a corresponding reduction in blood pressure for many individuals. As usual, the most notable improvements in blood pressure and cholesterol occurred in individuals with pre-existing elevated levels. Some age-related markers improve in mice when supplemented with (-)-epicatechin, although no direct increase in lifespan has yet been noted.
Supplementation with some form of cocoa (supplemented or consumed as ultra-dark chocolate) may be beneficial for some individuals, although consuming too much sugar with cocoa would likely offset any positive effects. Quality cocoa extract is more expensive than many of the other supplements listed on this page, coming in at $1-2 day for a proper dosage.
CoQ10 [Examine, webmd, Wikipedia] (Coenzyme Q10 / ubiquinone) is a substance found in meat and fish that is primarily present in mitochondria and aids ATP production. Although supplementation is likely safe, it’s difficult to find convincing evidence that CoQ10 supplementation would be effective for longevity. It may improve lipid peroxidation, blood flow and offer minor improvements in other areas, but in my opinion doesn’t appear to stand out from most supplements, both experimentally and theoretically.
Creatine [Examine, webmd, Wikipedia] is an organic compound used in the recycling of ATP in humans. It can be found in notable amounts of muscle meat and can also be synthesized in humans via glycine, arginine, and methionine. Creatine is a very popular supplement for athletes with strong evidence that it notably increases power output and lean mass, with some evidence that it can offer minor improvements in related areas such as recovery, fatigue, and some biomarkers that are positively associated with quality anaerobic exercise. It’s very safe, has little potential for any side effects, and is relatively cheap. The only reason I don’t take creatine right now is that I’m not doing many activities to build muscle, although I’ll likely start taking it soon, even if only alongside basic resistance training, calisthenics, or even cardio.
Curcumin [Examine, webmd, Wikipedia] is a pigment found in tumeric. Curcumin’s strongest benefit seems to be the reduction in inflammation that it offers, although there appear to be some other areas that may be improved as well such as lipid profiles, mental health, potentially improved digestion, and reduced pain with some conditions such as osteoarthritis. It may exhibit a notable anti-tumor effect via apoptosis. It seems relatively safe, although has low bio-availability, so is often taken with substances to increases its availability such as piperine, or taken in an otherwise proprietary formulation that generally has some type of oil that improves bio-availability instead. As inflammation is important in aging and many other diseases, it’s something that is nice to be aware of.
I previously took curcumin, but as my inflammation is now very low (and can barely be shown to be lower with the type of blood panels I usually get), I’ve stopped taking it for the time being. Curcmin can be potentially tough on the liver, and in large doses has a greater potential to cause adverse affects. Some papers show quite a few potential drug interactions that can occur by taking curcumin, especially in larger doses, and via a variety of mechanisms, including its affect on platelets and potential interactions with enzymes such as CYP3A4, potentially affecting the metabolism of a large amount of drugs.
Quercetin [Examine, webmd, Wikipedia] is a flavanoid found in fruits and vegetables. As usual, eating the right fruits and vegetables is good for you on its own, and may make supplementation less beneficial, or completely irrelevant. I likely get enough of this from my diet, although there may be benefits to infrequent high-dose supplementation.
L-carnitine [Examine, webmd, Wikipedia] is an ammonium compound found in notable quantities in meat such as beef. Supplementation sometimes appears to offer some decent results, but I’ve determined that I like already get a sufficient amount from my diet.
PQQ [Examine, Wikipedia] is a redox cofactor found in human breast milk and some foods such as kiwis. PQQ alters indicators of inflammation and mitochondrial-related metabolism. It’s likely very safe, the main reason I’m not currently taking it is there’s very little evidence showing that it notably benefits already-healthy young humans, and it costs a bit higher than most supplements on this page.
Resveratrol [Examine, webmd, Wikipedia] cannot go without being mentioned, as the extract from grapes that inspired the ‘red wine is great for you’ craze many years ago, it has been a constant source of speculative benefits and is still a very popular supplement in longevity communities. Although it hasn’t quite lived up to its initial hype, there’s still a lot of research on how it may be beneficial for longevity in one way or another. A summary is currently excluded here and you’re encouraged to read the above links if interested.
Sulforaphane [Examine, webmd, Wikipedia] is a compound found in vegetables such as broccoli and cabbages, with the best sources of it being broccoli sprouts and cauliflower sprouts. I’ve taken sulforaphane previously, but it will be difficult to know if it had a notable effect on me or not. I’m currently focusing more on my diet and have decided against taking sulforaphane. I’ve excluded a research summary in favor of the above links.
Trimethylglycine [Exmine, Wikipedia] is a betaine amino-acid derivative found in some plants. It is notable for reliably reducing homocysteine levels in healthy subjects, sometimes by as much as 10%, and as much as 10-40% in unhealthy individuals. It appears that it might have a slightly negative effect in increasing, or preventing to some extent a decrease in, LDL, which is why I’m currently not taking it. It’s a nice molecule to be aware of and might deserve a spot in my stack at a later point, but as usual it would be nice to have more research available.
A lot of supplements have been excluded from this list, including many which are very interesting. Individuals who follow nootropic or longevity communities will definitely be curious why their favorite substance may have been excluded from this page, to which my answer is mostly that there’s too many substances for me to include all of them, so I did quite a bit of picking personal favorites. Even so, there’s likely many substances I’d like to include, but which I haven’t yet heard about or done enough research on. Feel free to message me on Twitter if you have any great suggestions here.
More interesting and potentially unsafe substances
This section contains some brief notes and links on substances that appear to be a lot more ‘experimental’ than the above sections, but have some interesting potential. In some cases it’s impossible to find proper tests of safety, or even basic toxicity, in humans. Regardless, they’re all interesting chemicals, sometimes increasing the lifespan of organisms such as mice by large amounts. A lot of compounds have been excluded from this list as there are too many for me to list currently. The most interesting item of this list is currently rapamycin, by a large margin. Also see list of potential CRMs.

rapamycin notably extends the lifespan of most organisms we have given it to thus far, but lacks proper research in humans aside from its use as an immunosuppressant. It’s a very popular drug to research in the area of longevity, and deserves a longer write-up than I’ve given it here; I may even start taking it in the near future.
