Tried a Probiotic but Still Dealing with Gut Issues?
You’re not alone. Many generic probiotics contain only a handful of bacterial strains – 5, 10, maybe 20. But your gut microbiome is an ecosystem of over 100 different bacterial species working together, similar to a garden or rainforest. Taking a supplement with just a few strains is like trying to replant a rainforest with a few seeds from the same tree – it simply can’t restore what’s missing.
Here’s how we’re different…
It's not just about better poops
