Overview
This KAL capsule delivers fully chelated magnesium glycinate (bisglycinate chelate) with added BioPerine, 240 vegetarian capsules covering 60 four-capsule servings, formulated gluten free and vegan for stress, relaxation, muscle and bone support.
The chelated glycinate form is generally considered gentler on the stomach than magnesium oxide or citrate, which is why it is often chosen by people sensitive to other forms. BioPerine, a black pepper extract, is included to support absorption, though the effect varies by individual.
- Magnesium bisglycinate chelate form
- BioPerine added for absorption
- 240 vegetarian capsules, 60 servings
- Gluten free and vegan
Who it's for
For people who want magnesium in glycinate form for muscle, sleep or stress-related support without the digestive side effects some cheaper magnesium forms cause. Not for anyone who wants a one or two capsule daily regimen.
Strengths and trade-offs
Drawn from this product's published specifications.
- Chelated glycinate form is gentle on digestion
- Gluten free and vegan capsules
- BioPerine added for absorption support
- Four capsules per serving shortens the effective supply
Performance notes
Magnesium bisglycinate binds the mineral to glycine, a form generally absorbed with less digestive upset than magnesium oxide or citrate, and BioPerine is added here to support that absorption. With 240 capsules covering 60 servings, the label implies four capsules per serving, so daily use draws down the bottle faster than the total count alone suggests.
