Tru Niagen is the consumer supplement line launched in 2016 by ChromaDex, a science-focused company whose story began with reference standards in 1999. Its signature ingredient, Niagen, is the company’s patented form of nicotinamide riboside, and the brand builds its range around daily supplement routines rather than a long list of unrelated wellness products. Tru Niagen comes in vegetarian capsules and mixable stick packs, with dedicated Beauty and Immune formulas alongside foundational and Pro options. That gives shoppers comparing Tru Niagen NAD+ supplements clear choices for a sale search or promo codes, while secondhand and resale listings for supplements deserve extra care. Phia can compare Tru Niagen prices, test coupon codes at checkout, and find Tru Niagen secondhand and resale listings to review before choosing a sealed, in-date product.
