"Serious adverse effects have not been reported with taurine supplementation. The highest dose used in a human trial was 10 grams per day for 6 months, and the longest human trial was 12 months and used a dose of 0.5–1.5 grams per day. Based on the available evidence, it’s suggested that 3 grams per day can be consumed indefinitely without risk of side effects."
"The observed safety limit, the highest dose for which one can be relatively assured that no side effects will occur over a lifetime, has been suggested to be 3g of taurine in supplemental form (in addition to food intake) a day.[140] Higher doses have been tested and well tolerated, but not enough evidence is available to suggest lifelong safety of said doses.
There is a notion that taurine causes heart damage, which is currently unsupported (and contrary to a fair bit of evidence). This appears to be due to a misunderstanding of why serum taurine levels are elevated during cardiac failure (which is from taurine leakage from cells)."
My advice, however, is to not take it for antiaging until the science is done on humans, specially at high doses.
