Solaray Magnesium 200 mg features a combination of Magnesium Amino Acid Chelate Complex and Magnesium Oxide in VegCaps. The Amino Acid Chelate Complex implies a well-absorbed form, similar to bisglycinate, which is good for systemic magnesium delivery and gentle on the stomach.
However, the inclusion of Magnesium Oxide, even alongside a better form, detracts from the overall quality for systemic repletion. Magnesium Oxide is largely used for its laxative properties due to its low bioavailability, meaning much of that magnesium isn't absorbed for cellular functions.
This blend might be suitable for individuals looking for a moderate amount of bioavailable magnesium with a potential mild digestive aid, but it's not the most efficient choice for maximizing systemic magnesium levels due to the mixed forms.
