I have not yet spent a lot of time on this blog discussing supplements, because I think the focus of good health should be the basics: healthy diet, exercise, good sleep, stress management, and the avoidance of toxic substances such as drugs, tobacco, and excessive alcohol.
This is not to say that supplements don’t have a role, but as a category they suffer from a number of problems. They often are not backed by large and robust studies. The studies that do exist tend to be funded by companies who stand to profit from the supplement, thus introducing the same conflict of interest that “big pharma” is often guilty of with prescription medications. They are not well regulated, so even if “substance X” is truly safe and terrific for your health, you have little guarantee when you purchase “substance X” that you are actually getting “substance X”, unless you make sure to purchase from a reputable place like FullScripts (linked here in case you are interested). And supplements can give people a false sense of security – “I take a multivitamin, and therefore I don’t need to worry about eating healthfully,” or “I take creatine, so I don’t need to actually do a workout” are foolish and potentially dangerous ideas.
With that said, I get asked about this topic a LOT, so I’m going to start periodically reviewing various supplements.
First up in today’s post: NAD+ (and the supplements which help to raise NAD+, namely NMN and NR), which a number of patients have asked me about in the past few months. This is a long and complicated topic and I had to do a lot of research to get up to speed on it, so I am going to break this post into two separate parts, one today and one a week from now. But first let me just give the punchline for those of you who don’t want to read my long ramblings:
