“Trusted by millions, Tru Niagen is the #1 NAD+ supplement for healthy aging in the U.S., with more than 8 million bottles sold to date.”

Trusted by Science, Backed by Research: Tru Niagen is a patented NAD+ supplement that has been clinically proven to safely and effectively increase NAD+ levels by over 50% in just two weeks with daily use. NAD+ is essential for healthy cell function, repair, and energy.

Vital for Cellular Energy & Healthy Aging: NAD+ levels naturally decline with age—up to 65% between ages 30–70. Tru Niagen helps restore these levels, supporting brain health, muscle recovery, heart health, and overall cellular resilience to metabolic stress.

Clinically Proven & Patented Formula: Powered by Niagen (nicotinamide riboside, NR), a unique form of vitamin B3, Tru Niagen is more efficient at boosting NAD+ than other precursors such as NMN or niacin. With decades of research, 50+ patents, 400+ published scientific studies, and 30+ clinical trials, Tru Niagen is one of the most trusted supplements in the world.

Pure, Safe, and Tested: Every batch of Tru Niagen is made in the USA with globally sourced ingredients, manufactured in cGMP certified facilities, and tested by third-party ISO/IEC accredited labs for safety, potency, and purity. Vegetarian, gluten-free, nut-free, caffeine-free, with no artificial flavors or colors.

Endorsed by Experts: Supported by decades of science and recognized by two Nobel Prize-winning scientists, Tru Niagen is a one-of-a-kind supplement that helps you age better, live stronger, and feel more energized every day.
