Frtil Magnesium Glycinate.

The rest of the FRTL line is whole-food sourced. Magnesium Glycinate is their one intentional exception — and they say so plainly. The elemental magnesium comes from naturally occurring salt brine, chelated with glycine for bioavailability and digestive comfort. That form matters: magnesium glycinate is widely considered the gentlest option, which is relevant for anyone navigating the particular demands of the conception season, pregnancy, or the fourth trimester. FRTL's transparency about what this is — and what it isn't — is consistent with why we trust the rest of their line. Clean ingredients. Vegan capsule. Same sourcing honesty.
