Why Glycine?
Read moreGlycine is known for its calming, anti-inflammatory properties. It also supports immune modulation and thyroid function, which is why it’s central to our formula.
-
Why Avoid B6?
Read moreUnlike most water-soluble vitamins, B6 can build up in the body, and in some people, that can lead to nerve sensitivity or damage over time. We leave it out for good reason.
-
Why No B9 & B12?
Read moreFolate and B12 are important, but not everyone processes them the same way. We leave them out to better support sensitive systems and individual needs.
