NAD is a molecule your body makes naturally\u2014and it\u2019s in every single cell. Scientists have known about NAD for more than a century, but research has only begun to explore its role in aging and disease within the past decade.<\/p>\n<p data-journey-content=\"true\" data-node-id=\"1\" class=\"css-6wxqfj emevuu60\">NAD levels naturally drop as we get older, but some companies have supplements on the market that can help reverse this trend. That leads to the big questions: How  does a NAD supplement work, what are the benefits, who should take them, and what does research  show? As a dietitian familiar with NAD supplements, I have answers. <\/p>\n<p data-journey-content=\"true\" data-node-id=\"2\" class=\"css-6wxqfj emevuu60\"><strong data-node-id=\"2.0\">Read more: <a href=\"https:\/\/www.womenshealthmag.com\/health\/g64703629\/best-supplements-for-women\/\" data-vars-ga-outbound-link=\"https:\/\/www.womenshealthmag.com\/health\/g64703629\/best-supplements-for-women\/\" data-vars-ga-ux-element=\"Hyperlink\" data-vars-ga-call-to-action=\"Best Supplements\" data-node-id=\"2.0.0.1\" class=\"body-link css-7bauu1 emevuu60\" rel=\"nofollow noopener\" target=\"_blank\">Best Supplements<\/a><\/strong><\/p>\n<p>What does a NAD supplement do, and how does it work?<\/p>\n<p data-journey-content=\"true\" data-node-id=\"5\" class=\"css-6wxqfj emevuu60\">NAD supplements provide precursors\u2014molecules your body can convert into NAD\u2014to help boost levels.

Human research is limited to small trial sizes, and the findings have been inconclusive, so it\u2019s still unclear how well these findings actually apply to people. <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S2468501121000055\" target=\"_blank\" data-vars-ga-outbound-link=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S2468501121000055\" data-vars-ga-ux-element=\"Hyperlink\" data-vars-ga-call-to-action=\"Researchers\" data-node-id=\"9.7\" class=\"body-link css-7bauu1 emevuu60\" rel=\"nofollow noopener\">Researchers<\/a> are also curious about  whether a NAD supplement can help extend the years of life we have in good health. <\/p>\n<p data-journey-content=\"true\" data-node-id=\"10\" class=\"css-6wxqfj emevuu60\">In short, NAD supplements may offer potential benefits for healthy aging, but more research is needed to determine who benefits most and how best to use them. <\/p>\n<p>What happens if you take a NAD supplement daily?<\/p>\n<p data-journey-content=\"true\" data-node-id=\"12\" class=\"css-6wxqfj emevuu60\">Daily supplementation with NAD precursors is generally considered safe, and some animal studies suggest it can boost NAD levels in the blood, muscles, brain, and immune cells. That\u2019s why researchers are looking closely at daily NAD supplementation as a way to support healthy aging, energy metabolism, and overall cellular function.<\/p>\n<p data-journey-content=\"true\" data-node-id=\"13\" class=\"css-6wxqfj emevuu60\">That said, not everyone responds the same way. Anecdotally, users of NAD supplements report mixed results, ranging from better energy and focus to no noticeable changes.
