Does magnesium glycinate suppress appetite? Evidence does not establish a hunger treatment

The inspected sources do not establish magnesium glycinate as a reliable appetite suppressant. A small change in body weight in pooled magnesium studies does not prove reduced hunger or a glycinate-specific effect. Poor appetite can also be a symptom of deficiency, illness or gastrointestinal intolerance.

A weight outcome is not an appetite outcome

A 2026 review found a modest average reduction in body weight across magnesium trials, while body fat percentage and BMI did not significantly change overall. That finding does not establish appetite suppression, and it cannot automatically be attributed to every glycinate product. [1]

Deficiency can reduce appetite rather than increase it

NIH includes loss of appetite among early magnesium-deficiency symptoms. This does not mean that everyone with poor appetite is deficient, or that taking extra magnesium will deliberately suppress hunger. Nutrient adequacy and weight-control treatment are different goals. [2]

Nausea is not a desirable weight-management mechanism

Higher supplemental magnesium exposure can cause nausea, cramps or diarrhea. If a product makes eating unpleasant, that is a tolerability problem to review, not evidence that it is a safe appetite-regulating treatment. [2]

Glycinate does not establish a special appetite dose

The inspected review does not identify an optimal glycinate regimen for hunger control. Increasing elemental magnesium to chase an appetite effect raises adverse-effect concerns, particularly with impaired kidney function. [1][2]

Unexplained appetite and weight changes deserve assessment

Imagine someone eats less after starting a supplement but also has persistent nausea and unintentional weight loss. NHS recommends assessment of unexplained ongoing weight loss. Do not assume the product is delivering a beneficial appetite effect. [3][2]
