A Longevity Expert’s Guide to the Best NAD+ Supplements

NAD+ (Nicotinamide Adenine Dinucleotide) has surged in popularity as a key molecule linked to longevity, cellular energy, and overall health. As age diminishes NAD+ levels naturally, supplementation has become essential for those seeking to support healthy aging, bolster metabolism, and promote DNA repair.

However, not all NAD+ supplements are created equal. To truly reap the benefits, product quality, purity, and compliance with regulatory standards matter greatly. This guide, drawing from expert insights and research including Vogue’s review of top NAD+ supplements, offers an inside look at the best supplements on the market — and how lab testing by trusted partners like Qalitex ensures excellence.

Why NAD+ Supplement Quality Matters

NAD+ supplements commonly come in forms such as NAD+ precursors like NMN (Nicotinamide Mononucleotide) and NR (Nicotinamide Riboside). Because of their delicate chemical structures and the high demand for anti-aging products, the risk of contaminants or inaccurate labeling hikes significantly.

Choosing supplements tested by an ISO 17025 accredited testing laboratory guarantees verified potency and safety. Qalitex, based in Southern California, stands out as a leading lab offering:

• Heavy-metal analysis for supplements to ensure no toxic metals like lead or arsenic are present (Heavy Metal Analysis for Supplements).
• Microbiology testing services to certify microbial limits are within safe thresholds (Microbiology Testing Services).
• Certificate of Analysis (CoA) testing — providing official documentation of quality and ingredient composition (Certificate of Analysis (CoA) Testing).
