Most promising anti-aging compounds (2021)

There are more than 200 different geroprotective compounds. Some of these are already available as supplements, some are in clinical trials and some have FDA approval. Which are my top five that I think I most promising in terms of their anti-aging effects (so focusing more on healthspan than lifespan). And note the use of “promising” – there is still much work to be done to better investigate the long-term safety, dose and timings of different supplements which you should always bear in mind.
