Most people taking supplements are wasting their money — not because supplements don't work, but because what they're swallowing never actually reaches the cells that need it. Bioavailability scientist George Kokkinis has spent 30 years at the intersection of chemistry, regulation, and human performance, and what he shares in this episode will change how you read every supplement label. From vitamin D3 and NMN to berberine, CoQ10, and omega-3s, we break down what's actually getting absorbed, what's heading straight to the toilet, and what to look for before you spend another dollar. This is the supplement conversation nobody in the industry wants you to have.
