Serving size stated by the manufacturer: 3 capsules.
Scientific background
Independent researchMagnesium
Magnesium is an essential mineral involved in hundreds of enzyme reactions, including energy metabolism, muscle contraction and nerve function2.
EFSA set adequate intakes of 350 mg a day for men and 300 mg a day for women, from all sources3. Supplements supply magnesium bound to different partners, such as oxide, citrate or glycinate. Labels should state the amount of elemental magnesium, which is lower than the weight of the compound.
Research evidence
Independent researchMagnesium
Authorised EU claims include that magnesium contributes to a reduction of tiredness and fatigue, to normal muscle function and to normal functioning of the nervous system, for foods that are a source of magnesium4.
For exercise performance, a review found that supplementation may help people with low magnesium status or older adults, but found no clear benefit in people who already have enough magnesium5.
For this product
Each capsule contains 650 mg of magnesium bisglycinate chelate, providing 130 mg of elemental magnesium, according to the manufacturer. The manufacturer's serving of 3 capsules would provide 390 mg of elemental magnesium, more than EFSA's adequate intake of 300–350 mg a day from all sources3.
Evidence limitations
Independent researchNo published study has tested this specific product; the research summarised here concerns the ingredient itself.
Safety & potential risks
For this product
3 capsules a day (390 mg elemental magnesium) is above the tolerable upper intake level of 250 mg a day for supplemental magnesium1. That limit was set for readily dissociable magnesium salts on the basis of mild, reversible diarrhoea, and whether it applies in the same way to the bisglycinate chelate has not been established. Do not exceed the label serving, and ask a doctor or pharmacist if you have kidney problems or take other medicines.
- Do not exceed the recommended daily dose.
- Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.
- Keep out of the reach of young children.
Magnesium
The EU Scientific Committee on Food set a tolerable upper intake level of 250 mg a day for magnesium from supplements and fortified foods (readily dissociable salts and compounds such as magnesium oxide), based on mild, reversible diarrhoea as the most sensitive effect. Magnesium in normal food is not included1.
People with impaired kidney function can accumulate magnesium and should only supplement under medical advice. Magnesium can reduce the absorption of some antibiotics and osteoporosis medicines, so separate them by several hours or ask a pharmacist2.
Regulatory status
Sold as a food supplement. Health claims shown are authorised EU claims (Regulation 432/2012) and apply at the stated daily amount.
