Thorne’s Riboflavin 5'-Phosphate delivers vitamin B2 in its active, tissue-ready form—designed for easy absorption and daily support. Vitamin B2 (riboflavin) helps your body unlock energy from food, supports your nervous system, and helps keep your skin, vision, and red blood cells in good shape. It also plays a role in protecting your cells from oxidative stress and helps your body use iron effectively. With just one convenient capsule, you can give your body the support it needs to keep up with your busy lifestyle.
Unlike many supplements, Thorne’s Riboflavin 5'-Phosphate is not derived from yeast and delivers riboflavin in its bioactive, tissue-ready form, allowing the body to use it directly without conversion. This ensures optimal absorption and effectiveness. By taking this supplement, you support your energy metabolism and overall cellular function with a form your body can readily use.
Thorne sets the standard for excellence in the supplement industry. Recommended by over 100 professional sports teams and U.S. National Teams, Thorne offers a curated bundle of clean, science-backed supplements and treats designed to fuel your body naturally and effectively. With more than 30 years of dedication to quality, Thorne's commitment to purity and potency begins with sustainably sourced ingredients and rigorous testing. Every supplement undergoes four rounds of testing to ensure optimal absorption, safety, and efficacy, making Thorne the trusted choice for both health-conscious individuals and professionals.
