Important Disclosures

1. Supplements Are Not Medicines. Health Supplements that replenish NAD levels, like nicotinamide riboside, are not intended to diagnose, treat, cure, or prevent any disease.

​

2. No Medical Advice. I am a lawyer, and a journalist, not a doctor, and I offer no medical advice. But I do follow the science, and I may be able to bring to your attention some interesting studies, and help clarify what the studies may may or may not be saying. And check with your physician -- your physician can look at this research, too.

3. Commercial Affiliations. I am a ChromaDex shareholder, and a marketing affiliate for Amazon and Rakuten. As a result, I will sometimes mention or recommend products that I endorse, like Tru Niagen, which I take every day.
