Magnesium Glycinate 350mg
Solaray provides a high-quality, fully reacted bisglycinate form, which avoids the common industry practice of 'buffering' with poorly absorbed magnesium oxide. The product explicitly lists 350mg of elemental magnesium per serving, meeting a key transparency indicator, and includes BioPerine to further support absorption at a very competitive price point per dose.
