Magnesium 250 mg Tablets

Price varies
USP VerifiedBudget-FriendlyMagnesium Oxide

While this product is USP Verified, ensuring purity and dosage accuracy, it uses magnesium oxide, which has a very low bioavailability (~4%) compared to chelated forms. It is a safe and accessible budget option but is less effective for improving systemic magnesium levels than the gold-standard bisglycinate.
