Probiotics: what the biggest YouTube health voices say

Dr. Eric Berg’s take: Advises taking a probiotic alongside antibiotics, since microbiome diversity does not fully recover, and adding fermented foods regularly.

Huberman Lab’s take: Includes probiotics and prebiotics among foundational supplements, best covered through a broad-spectrum product, to raise overall health, as long as nutrition and behaviors stay in order.

Thomas DeLauer’s take: Prefers fermented foods first, but endorses a quality probiotic as the one supplement worth taking when changing diet, citing personal experience and an affiliate link.

Layne Norton (Biolayne)’s take: Considers the evidence for probiotics weak and unproven; the studies are confounded or industry-funded, so more research is needed. Prioritises fibre and yogurt as foods.
