Adrien Grusse
Founder of Micron
Adrien is the founder of Micron, the app that helps more than 150,000 users track their micronutrients daily. Before Micron, he worked on the Growth team at Finary (Y Combinator). Adrien is not a credentialed dietitian — his role here is to translate the scientific literature into accessible content, rigorously. Every article cites peer-reviewed sources (PubMed, Cochrane, recent meta-analyses); no claim is made without a verifiable reference. For individual medical follow-up, consult a healthcare professional.
