Our Story
Science-backed immune health — rooted in over 25 years of research, unwavering dedication, and a belief that nature already has the answer.
Meet Dr. Samuel E. Silva, PhD
Dr. Samuel E. Silva has dedicated his life to one mission: understanding how natural compounds can support the human immune system. With a deep passion for science that started early and never let go, he built a career at the intersection of research and real-world health — driven by the belief that the most powerful solutions are the ones nature already provides.
Dr. Sam earned his PhD in Pharmacognosy from Philadelphia, PA, and has spent over two decades studying how beta-glucans interact with our immune defenses at a molecular level.
In 2016, he founded SEMS Biofarma — a research-driven laboratory committed to turning that knowledge into real-world health solutions. Four years later, in 2020, he founded Relevant Nutrition in the United States to bring this science to American families and healthcare professionals — because he believed that access to truly high-quality immune support shouldn't depend on where you live.
What started in the lab grew into something much larger. Today, SEMS Biofarma's flagship product — Biovit Bioglucan® — is trusted and recommended by physicians, oncologists, and nutritionists in Brazil, where it is also available through thousands of pharmacies. Biovit has recently launched in the United States through Relevant Nutrition, bringing Dr. Sam's research and decades of experience to the U.S. market. Dr. Sam's work bridges decades of scientific research with everyday immune health — making clinically studied formulations accessible to the people who need them most.
Why Relevant Nutrition Exists
Most supplement companies start with a marketing idea and work backward to find an ingredient. We did the opposite. Relevant Nutrition was born from decades of laboratory research and clinical observation — the product earned its reputation long before we ever ran an ad.
Our mission is simple: deliver scientifically backed, premium-quality immune health solutions that healthcare professionals can confidently recommend and families can trust. No hype. No shortcuts. Just science that works — the way nature intended.
Biovit Bioglucan®
Biovit Bioglucan® is our flagship — a liquid beta-glucan 1,3/1,6 supplement derived from Saccharomyces cerevisiae and suspended in a Camellia sinensis (green tea) infusion. It represents over 25 years of continuous research, built on the understanding that the form of a supplement matters just as much as the ingredient itself.
What sets Biovit apart is its liquid formulation. Unlike powdered or encapsulated beta-glucans that can undergo molecular fragmentation during processing, Biovit's liquid suspension preserves the intact long-chain molecular structure — the form recognized by the immune system's Dectin-1 receptors. In simple terms: the body can actually use what you're taking.
The result is a supplement that supports immune modulation — helping the body find balance rather than simply stimulating it — at effective doses as low as 10–15 mL per day, with no known drug interactions, and suitable for the whole family.
