You can barely open a browser without seeing an ad for probiotics. Most claim to “rebalance your microbiome” or “boost immunity,” often with zero transparency. But rigorous science tells a messier story. For example, a recent meta-analysis in Nutrients found that while certain probiotic strains (Lactobacillus rhamnosus GG, for example) can improve symptoms of irritable bowel syndrome (IBS), results are highly variable, and benefits don’t extend to everyone equally. Brain supplements (nootropics) have officially left the biohacker basement and are now a $10 billion industry. But which ingredients actually work? The answer, again, is nuanced. https://www.latimes.com/l.. #Biohackers Connect #Gut Health
