KAL, Chelated Magnesium Bisglycinate, 180 Tablets

Three tablets provide 315 mg elemental magnesium from fully chelated magnesium bisglycinate, with no added sleep actives. The label markets relaxation support and makes the elemental amount clear. KAL says it is lab-tested for purity and potency, but no named independent certification or public product-specific certificate was found.

Our Verdict

Its form, 315 mg dose and active-ingredient value are stronger than most budget products. It remains fourth because the highest-weighted testing criterion is supported only by an unlinked brand claim.

Alternatives to Consider

Thorne, Magnesium Bisglycinate, 6.5 oz (187 g)

Thorne

Each scoop supplies 200 mg of elemental magnesium as magnesium bisglycinate, with citric acid and monk fruit as the only other ingredients. The label positions the powder for pre-bedtime use, and the exact 187 g product is listed in NSF's Certified for Sport directory.

Natural Factors, Stress-Relax, Nighttime Magnesium Bisglycinate

Natural Factors

One scoop contains 200 mg elemental magnesium as bisglycinate plus 100 mg GABA, 50 mg L-theanine and 2.5 mg melatonin, with every active disclosed. It is explicitly labeled for bedtime and carries the ISURA Verified Clean and Non-GMO marks. This is a multi-ingredient sleep formula, not a magnesium-only product.

California Gold Nutrition, Magnesium Glycinate, 133 mg, 180 Capsules

California Gold Nutrition

The Supplement Facts panel declares 400 mg elemental magnesium from magnesium glycinate per three-capsule serving and no added melatonin, GABA or L-theanine. iHerb marks the SKU iTested and offers a product certificate. The overview also calls the formula buffered without naming a separate buffering salt, which reduces form transparency.
