Does Magnesium Support Weight Loss?

What's the buzz about magnesium for weight loss? Learn more about the research.

Magnesium, an essential mineral, is making waves in the wellness world for its numerous health benefits. A key player in cellular function, magnesium is essential for over 300 biochemical reactions in the body.(1) From supporting heart health to promoting restful sleep, this mighty mineral is a game-changer. But did you know that magnesium could also aid in weight loss? Let's dive into the science behind it.

How Can Magnesium Help with Weight Loss?

Magnesium is involved in numerous processes that can influence weight loss, including energy production, blood sugar regulation, and hormone balance.(2) But how exactly does magnesium contribute to shedding those extra pounds?

  • Boosting metabolism: Magnesium plays a critical role in energy production, converting the food we eat into energy our cells can use.(3) With a healthy metabolism, your body can burn calories more efficiently, helping you lose weight.
  • Blood sugar control: Magnesium helps regulate blood sugar levels by enhancing insulin sensitivity.(4) Balanced blood sugar levels can prevent overeating and reduce fat storage, promoting weight loss.
  • Reducing inflammation: Low magnesium levels are linked to increased inflammation, which may contribute to weight gain and obesity.(5) Magnesium can help reduce inflammation, supporting weight loss efforts.

What Does Research Say About Magnesium and Weight Loss?

Several studies have found a connection between magnesium intake and weight loss. Let's explore some of the key findings:

  • Magnesium and weight loss in women: A study conducted on overweight and obese women found that magnesium supplementation led to a significant decrease in weight and body mass index (BMI).(6) The women received 250 mg of magnesium per day for eight weeks, which resulted in an average weight loss of 2.2 kg.
  • Magnesium, insulin sensitivity, and body composition: Another study found that magnesium supplementation improved insulin sensitivity and reduced fat mass in overweight individuals with low magnesium levels.(7) Participants received 365 mg of magnesium daily for six months, resulting in improved body composition.
  • Magnesium and metabolic syndrome: A systematic review and meta-analysis of randomized controlled trials showed that magnesium supplementation could improve components of metabolic syndrome, a group of conditions that increase the risk of heart disease and diabetes.(8) These improvements included reduced waist circumference and blood sugar levels, both of which are important factors in weight loss.


Which Forms and Dosages of Magnesium Are Best for Weight Loss?

While there are several forms of magnesium available, some are more suited to weight loss goals than others. Magnesium citrate and magnesium glycinate are two forms known for their high bioavailability, making them effective choices for raising magnesium levels in the body.(9) This is why our Night Minerals Magnesium + Calcium Drink combines both of these forms.

As for dosage, the Recommended Dietary Allowance (RDA) for magnesium varies based on age and sex.(10) However, when it comes to weight loss, studies have used dosages ranging from 250 mg to 365 mg per day.(6,7) 

Are There Any Risks or Side Effects Associated with Magnesium Supplementation?

While magnesium is generally safe for most people, excessive intake can lead to side effects such as diarrhea, nausea, and abdominal cramping.(11) Additionally, certain medications, like diuretics and proton pump inhibitors, can interact with magnesium supplements.(12)

Magnesium is an essential mineral with a myriad of health benefits, including its potential role in weight loss. Through boosting metabolism, regulating blood sugar, and reducing inflammation, magnesium can be a valuable addition to your weight loss journey. Scientific research supports the use of magnesium supplementation for weight loss, with studies showing significant improvements in body composition and metabolic health.

When choosing a magnesium supplement for weight loss, opt for forms like magnesium citrate and magnesium glycinate, known for their high bioavailability. Dosages used in studies range from 250 mg to 365 mg per day. Remember that while magnesium can be a powerful ally in your weight loss efforts, it's essential to pair supplementation with a balanced diet and regular physical activity for optimal results.
