Born in Brazil.
Made in the USA.
Our company was built on a clear mission: to create science-driven supplements that deliver real, measurable results. In an industry often dominated by trends and marketing claims, we focus on evidence, quality, and consistency. Founded by a PhD formulation scientist and a certified nutrition and fitness professional, the brand combines deep scientific expertise with real-world performance insight to raise the standard in supplementation.
Why our labels carry four colors
Green, yellow and blue come from the Brazilian flag. Red, white and blue come from the American one. Leandro and Michelle grew up in Brazil and built Proven Science Nutrition® in the United States, and the stripe on every tub is how they carry both.
The rule behind the brand is simple: clinically dosed ingredients, no proprietary blends, and third-party testing on every batch.
