Magnesium is not a mineral that directly causes weight gain or increases appetite. It plays a role in energy metabolism, muscle function, and many enzymatic processes in the body, but there is no strong scientific evidence showing that taking a magnesium supplement alone causes fat accumulation or a significant increase in appetite. However, the form of magnesium used, the other ingredients in the product, and the individual's diet may affect their experiences with weight or digestion. In this article, we address the questions of whether magnesium causes weight gain, whether it increases appetite, and what the effects of different forms of magnesium on weight are.
Does Magnesium Supplement Cause Weight Gain?
Magnesium supplements do not cause weight gain. Magnesium contributes to normal muscle function, normal function of the nervous system, normal psychological function, normal energy-production metabolism, and electrolyte balance. In cases of inadequate intake, fatigue and general weakness may occur; magnesium contributes to the reduction of fatigue and exhaustion. However, this condition is not directly related to weight gain. Weight gain is generally associated with the amount of calories consumed and overall lifestyle. Magnesium supplements have no decisive effect on weight gain.
Does Magnesium Increase Appetite?
There is no evidence that magnesium directly increases appetite. Magnesium contributes to normal muscle function, normal function of the nervous system, normal psychological function, and the reduction of fatigue and exhaustion. Magnesium has not been shown to have an increasing or decreasing effect on appetite. Changes in appetite may be linked to many factors such as diet, sleep, and daily living conditions.
Which Magnesium Causes Weight Gain? What Is the Difference Between Forms?
Magnesium supplements are produced with different compounds. The difference between forms is related to their absorption properties and prominent form characteristics; this difference is not a factor that determines weight gain. We addressed which type of magnesium is suitable for which need in a separate article.
Magnesium citrate is an easily water-soluble and commonly used form; for details, you can check the content titled what magnesium citrate does.
Magnesium malate is a form combined with malic acid and is frequently preferred for daytime use. Magnesium bisglycinate is a form bound to the glycine amino acid; what magnesium glycinate does is explained in a separate article. Magnesium taurate is a form combined with taurine, while magnesium L-threonate is combined with threonic acid. Although magnesium oxide has a high elemental magnesium ratio, it is a form with low water solubility.
Supplements differ not only by compound type but also by presentation format. There are effervescent (water-soluble) forms, tablet and capsule (pill) forms, and forms with specified daily usage amounts such as 365 mg. The presentation format and daily usage amount do not change the product's effect on weight.
| Form | Form characteristic | Effect on weight |
| Magnesium citrate | Commonly used form that is easily water-soluble | Has no weight-gaining effect |
| Magnesium malate | Form frequently preferred for daytime use | Has no weight-gaining effect |
| Magnesium bisglycinate | Form bound to glycine amino acid | Has no weight-gaining effect |
| Magnesium taurate | Form combined with taurine | Has no weight-gaining effect |
| Magnesium L-threonate | Form combined with threonic acid | Has no weight-gaining effect |
| Magnesium oxide | Form with high elemental magnesium ratio and low solubility | Has no weight-gaining effect |
In summary, no form of magnesium, including citrate, malate, bisglycinate, taurate, L-threonate, and oxide, has a weight-gaining effect.
Do Magnesium and Zinc Combinations Cause Weight Gain?
Many magnesium supplements on the market are offered in formulas combined with zinc or vitamin B6. Combined formulas such as 30 mg of zinc and 300 mg of magnesium are also in this group. These combinations have no weight-gaining effect, and there is no evidence that they increase appetite. Zinc and magnesium are minerals that play a role in normal metabolic processes in the body. Regardless of which formula or combination is preferred, weight change is related to the daily calorie balance and lifestyle, not the supplement itself.
Approved claims of magnesium, zinc, and vitamin B6
- Magnesium: contributes to normal muscle function, normal function of the nervous system, normal energy-production metabolism, and electrolyte balance.
- Zinc: contributes to normal macronutrient metabolism, normal carbohydrate metabolism, normal function of the immune system, and protection of cells from oxidative stress.
- Vitamin B6: contributes to normal energy-production metabolism, normal protein and glycogen metabolism, and regulation of hormonal activity.
None of these claims are related to weight gain or weight loss. You can review vitamin and mineral products, and evaluate multi-mineral formulas containing zinc and magnesium together to find the one suitable for your needs.
How Does Magnesium Deficiency Affect Metabolism and Weight Control?
Magnesium deficiency does not lead to weight gain. Symptoms that may occur with inadequate magnesium intake are related to daily living comfort and do not explain the change on the scale. We explained what happens in the body with magnesium deficiency in detail in a separate article.
Frequently reported symptoms of inadequate magnesium intake are as follows:
- Muscle cramps and a feeling of muscle twitching
- Feeling of fatigue and exhaustion
- Sleep irregularity
- General weakness
- Feeling of tension
- Decreased appetite
None of these symptoms are a cause of weight gain.
Magnesium contributes to normal muscle function, normal function of the nervous system, and the reduction of fatigue and exhaustion. Addressing inadequate intake through diet or supplements is not a process that causes weight gain or loss. Weight control is related to daily calorie balance, diet, and movement habits.
How Does Magnesium Affect Metabolism?
Magnesium contributes to normal energy-production metabolism, normal protein synthesis, normal muscle function, and normal function of the nervous system. When magnesium intake is inadequate, a feeling of fatigue and exhaustion may occur; magnesium contributes to the reduction of fatigue and exhaustion. It is important to get an adequate amount of magnesium through diet for a healthy metabolism.

Does Magnesium Use During Pregnancy Lead to Weight Gain?
Magnesium use during pregnancy does not cause weight gain. Weight gain is generally associated with the natural hormonal changes and increased nutrient needs experienced during pregnancy; magnesium has no direct effect on weight increase. During pregnancy, any decision to use a supplement must be made under a doctor's supervision.
