Product Overview

OnGuard goes beyond ordinary vitamins. Its heart is MycoFusion™, a patented complex that pairs shiitake with MaitakeGold 404™ — the maitake fraction Dr. Hiroaki Nanba spent years isolating and the University of Louisville confirmed is rich in “immune active” beta-glucans, granted U.S. Patent #5,854,404 because there is genuinely nothing like it. We layer that with colostrum, the antibody-rich first milk a mother cow makes only in the first days of her calf’s life, certified Grade A and collected solely from US dairies free of artificial hormones, antibiotics, and GMO.

Then we reach into traditions thousands of years old. Lo Han, the sweet Chinese melon Eastern healers have prized for centuries to support good health. And sacred lotus seed — the seed UCLA scientists found could still bloom after 1,288 years, supplying protective antioxidants studied for their role in healthy aging. The result is a far wider nutritional footprint than a single-ingredient pill, built for adults who want steady, everyday immune support. Shipped fresh from Sunrise, Florida by MDR, trusted for over 30 years by more than 2 million people.
