Our Verdict
The form, research-aligned dose, minimal ingredient list and exceptional value are stronger than the remaining uncertified products. Its low Third-Party Testing score keeps it below the independently verified top two despite leading the lighter-weight criteria.
Score Breakdown
Pros & Cons
Pros
- •The 300 mg elemental dose is close to the 250 mg magnesium-bisglycinate dose used in the cited sleep trial.
- •At about $0.06 per 100 mg of elemental magnesium, it has the list's lowest active-ingredient cost.
- •The panel lists only magnesium bisglycinate and citric acid, without a proprietary blend.
Cons
- •No USP, NSF, Informed Sport or published product-specific certificate is shown for the finished product.
- •The label requires one teaspoon to be diluted in at least 6 oz of water or juice, making it less convenient than tablets or capsules.
