About JYM Supplement Science

JYM Supplement Science is built on three things: Real Science, Real Solutions, and Unreal Results.

The products are what you take in—whether mixed as a powder or in capsule form. The results are what you see in the mirror, feel in the gym, and experience in everyday life: more muscle, less fat, greater strength, and improved health, confidence, and performance.

The science behind every JYM product is based on decades of research by Dr. Jim Stoppani, who has been studying supplements for over 20 years, dating back to his days at the University of Connecticut, his postdoctoral research at Yale School of Medicine, and his tenure as a science editor at major fitness publications.

Since 2013, JYM Supplement Science has helped millions of people reach their goals—whether they’re beginners or seasoned athletes. Our diverse product line supports performance, recovery, fat loss, hormone balance, and overall wellness, offering a solution for everyone.

Dr. Stoppani’s passion and expertise guide the JYM team. We take science and turn it into results that change people’s lives.
