Longevity Supplements Under Scrutiny: Half of Top NAD+ Pills May Contain Little to No NAD+
A recent round of independent testing has raised serious questions about the effectiveness of many so‑called longevity supplements. According to thorough checks by product testers, about half of the top-selling NAD+ supplements sold on major online marketplaces contain zero or negligible amounts of the very compound they promise to deliver. In parallel, another lab examination found that more than half of products marketed as NAD+ precursors were not accurately labeled, with only a fraction offering NAD+ or its precursors in amounts that align with what the labels claim. The findings come as a growing number of people in Thailand and across Southeast Asia seek anti‑aging and vitality products, often turning to the wellness market for plausible quick fixes.
