Human Clinical Trials

It is important to note that many pre-clinical studies have been conducted testing NR in various model systems. In 2015, the first human clinical studies were completed and the results demonstrated that NR safely and effectively boosts levels of NAD in healthy human volunteers.

In addition to these studies, there are approximately 21 additional human clinical trials studying NR in various endpoints which are currently underway or have recently completed. To get details on human studies underway, see below or visit
