Overview
•250mg dosage is below supplemental UL of 350mg, reducing GI upset risk vs higher oxide doses.
•Magnesium oxide has lower bioavailability (~4%), requiring consistent use for efficacy.
•Consult physician if kidney disease present, as impaired clearance increases hypermagnesemia risk.
•Take with meals to minimize stomach upset; safe for most adults short-term.
•Gluten-free, no artificial colors in tablets; USP-verified for quality.
•Not recommended exceeding dose or combining with other magnesium without medical advice.
