What is Magnesium?

Magnesium is a vital micronutrient essential for overall health. Found in nearly every cell in the body, it is especially concentrated in bones and muscles. Magnesium contributes to numerous physiological processes, including:

  • Muscle relaxation

  • Maintaining bone structure

  • Heart rhythm regulation

  • Protein synthesis

  • Nerve signal transmission

  • Glucose metabolism

  • Insulin production

  • Lipid metabolism

Magnesium and Weight Loss: How It Helps

Magnesium impacts almost every organ in your body, ensuring they function properly. But what is its specific link to weight loss?

How Magnesium Supports Fat Loss

Magnesium participates in energy production by helping metabolize the fats in your body. It also contributes to converting carbohydrates into energy instead of storing them as fat.

In other words, magnesium allows your cells to use calorie energy efficiently, supporting your metabolism and potential fat loss.

A deficiency in magnesium can disrupt fat metabolism and slow down weight loss efforts.

Magnesium’s Weight Loss Benefits

Magnesium affects weight loss in several important ways:

Appetite Regulation

Stress and fatigue can increase feelings of hunger, making it harder to lose weight. Magnesium supports energy production, allowing calories from food to be converted into energy instead of fat.

This regulation helps control appetite, sugar cravings, and snacking, making weight management easier. Without enough magnesium, excess calories are more likely to be stored as fat.

⚠️ Note: Restrictive diets often provide insufficient micronutrients. Maintaining proper magnesium intake helps avoid counterproductive effects that can hinder fat loss.

Long-Term Weight Management

Adequate daily magnesium intake supports stable weight over time. It reduces the need for restrictive diets, which often lead to magnesium deficiencies and other nutrient imbalances.

Ideal Daily Magnesium Intake

Daily magnesium needs vary by age, sex, and lifestyle. The general recommendation is approximately 6 mg per kg of body weight.

  • Example: A 60 kg adult should aim for around 420 mg of magnesium per day.

Higher needs occur in pregnant or breastfeeding women and adolescents during growth spurts.

How to Know If You’re Magnesium-Deficient

Magnesium deficiency is common. In France, 1 in 4 women and 1 in 6 men may be affected. Factors include:

  • Poor diet

  • High intake of processed foods

  • Restrictive dieting

  • Excess alcohol

  • Chronic stress

Common symptoms:

  • Extreme fatigue

  • Muscle pain or cramps

  • High stress levels

  • Anxiety, migraines, vertigo, insomnia, tingling, hyperemotionality

A blood test can confirm magnesium levels, with normal ranges between 0.7 and 1.1 mmol/L.

Magnesium Deficiency and Weight Gain

Low magnesium can increase stress and anxiety, triggering compulsive snacking and higher daily calorie intake, which can lead to fat storage and weight gain.

People with overweight or obesity often suffer from magnesium deficiency, contributing to metabolic syndrome—excess visceral fat and low “good” cholesterol levels. Supplementation with magnesium can support metabolic health in these cases.

How to Take Magnesium

Magnesium can be obtained through a balanced diet or via supplements if daily needs are not met.

Magnesium-rich foods include:

  • Dark chocolate and cocoa

  • Seafood and mollusks

  • Nuts and seeds (almonds, hazelnuts, walnuts, pistachios)

  • Fruits like bananas

  • Vegetables and legumes (chickpeas, beans)

  • Whole grains like brown rice

  • Magnesium-rich waters (e.g., Hépar, Rozana, sparkling waters)

Choosing Magnesium for Weight Loss

Supplements like Nutri&Co magnesium capsules combine multiple forms for optimal absorption. Benefits include:

  • Appetite regulation

  • Stress reduction

  • Increased energy and tonus

  • Digestive comfort (free from marine magnesium and citrate, which can act as laxatives)

Combining magnesium with vitamin B6 enhances overall health: reducing fatigue, supporting nervous system function, psychological well-being, and energy metabolism.

Other Nutrients That Support Weight Loss

Vitamin D

  • Crucial for metabolism and hormone regulation linked to weight control

  • Deficiency can impair fat loss

Iron

  • Essential for oxygen transport and energy production

  • Low iron leads to fatigue, reducing activity levels and slowing metabolism

Ensuring sufficient intake of magnesium, vitamin D, and iron can help maximize weight loss results naturally and sustainably.
