Even researchers from the pro-taurine anti-aging study recommend against experimenting with taurine, but if you want to give it a try, what daily dose might be best? It’s worth repeating that the researchers themselves who published the anti-aging study recommended against experimenting with taurine, as we have no long-term human safety trials. I introduced another potential parallel with another class of purported anti-aging supplements: NAD+ boosters like NMN and NR. As I covered in that video series, there were extraordinary lab animal benefits, like with taurine, but when they were tried in humans, they almost universally flopped. No wonder since NAD boosters affect tissue levels in rodents, but not in humans. And here we go again with taurine. It affects tissue levels in rodents, but apparently not us. So, might we expect to see the same flop? We won’t know until human trials are done, which will probably be never. In the meanwhile, what to do? I guess it depends on your tolerance for risk, but if you do decide to try it, I think a reasonable dosing would be half a gram, three times a day. Where should you get it? That’s the subject of the next video. This is the fifth video in a seven-part series on taurine. If you missed the previous ones, check out: • What Is Taurine in Energy Drinks?
