EP003: "Greek Yogurt Has Been Lying to You" — Two Stanford Athletes Built One That Actually Works

Описание: "I was eating Greek yogurt every day — a food I thought was probiotic. When I dug into the science, none of them are actually doing anything for my microbiome."

Elan Halpern was a Stanford athlete dealing with bloating, brain fog, and hormonal issues. When every road led back to the microbiome, she started making her own yogurt in her kitchen. Her roommate Kiki Couchman thought she was crazy — until she tried it.

Together they founded Sourmilk, a probiotic yogurt built like a supplement: 100 billion CFUs of Lactobacillus reuteri, a 10:1 protein-to-calorie ratio, and no compromises on what actually matters for your gut. They've hand-delivered 8,000+ yogurts across NYC in brown paper bags — what they call "the drug deal model."
