TRU NIAGEN is a premium NAD+ supplement designed to combat the natural decline of nicotinamide adenine dinucleotide (NAD+) as we age. This patented formula uses Nicotinamide Riboside (300mg per serving) to support the 37.2 trillion cells in your body, promoting energy production, DNA repair, and overall cellular health. It is ideal for adults aged 30 and above who want to maintain vitality and slow age-related health concerns.
The standout feature of TRU NIAGEN is its proprietary ingredient, Niagen, which is one of the most well-studied NAD+ boosters on the market. Backed by a Nobel Prize winner and over 500 scientific studies, it has achieved FDA recognition as both a New Dietary Ingredient and Generally Recognized as Safe. This ensures you get a product that is both effective and rigorously tested for purity and potency.

Buying Guide
Ingredient Profile: Pure NR vs. Synergistic Blends
Tru Niagen uses a single, patented form of nicotinamide riboside (NR) to boost NAD+ levels. It is straightforward and backed by extensive research. Thorne ResveraCel combines NR with resveratrol, quercetin, and betaine, aiming for a broader approach to cellular health. The Thorne Resveratrol Complex focuses on resveratrol, green tea extract, quercetin, and curcumin, targeting sirtuin activation without NR.

Dosage and Potency Options
Tru Niagen offers 300 mg and 1000 mg capsules, letting you adjust your dose as you age or face more metabolic stress. The 1000 mg version is clinically shown to raise NAD+ by up to 150% in three weeks. Thorne ResveraCel provides a fixed blend with 100 mg of NR plus resveratrol and quercetin, making it a lower NR dose but a multi-ingredient formula. The Thorne Resveratrol Complex delivers 150 mg of trans-resveratrol along with other polyphenols. Your choice depends on whether you want a high-potency NR supplement or a comprehensive antioxidant stack.
Research and Clinical Validation
Tru Niagen is one of the most studied NAD+ boosters, with over 500 published studies and 45+ clinical trials. Its ingredient, Niagen, has received FDA acceptance as a New Dietary Ingredient and Generally Recognized as Safe.
