Double Wood Magnesium Glycinate 400 mg

An NSF-certified magnesium glycinate option with 60 mg of elemental magnesium per capsule and 180 single-capsule servings.

Best For: Dose flexibility and NSF certification

Why choose it: Each capsule provides 60 mg of elemental magnesium, making the elemental dose easy to adjust in smaller increments, and the product is currently listed by NSF.

Avoid if: You have kidney disease, take medications that may interact with magnesium, or you might mistake the 400 mg magnesium-glycinate compound amount for 400 mg of elemental magnesium.

Trade-off: The large 400 mg front-label number refers to magnesium glycinate compound weight; the Supplement Facts panel lists 60 mg of elemental magnesium per capsule.

Quality Verification

NSF currently lists Double Wood Magnesium Glycinate 400 mg as a certified finished product. Double Wood also publishes batch testing for potency, heavy metals and microbial quality.

Safety Check

Do not interpret the 400 mg compound amount as 400 mg of elemental magnesium.
Review kidney function and medication interactions before using supplemental magnesium when relevant.
Count magnesium from other supplements and medications before increasing the number of capsules.

Dose note: The Supplement Facts panel lists 60 mg elemental magnesium per capsule. The 400 mg figure is magnesium glycinate compound weight, not elemental magnesium.
