Magnesium is a powerhouse mineral essential for countless bodily functions, including energy production, nerve health, and muscle function. But could adding a magnesium supplement to your routine help boost muscle mass and power?
A new study published in the International Journal of Molecular Science explores this question, uncovering how magnesium affects skeletal muscle health and performance. Here’s what the research found—and whether supplementing magnesium could support your strength-training goals.

What Does Magnesium Do for Your Body?
Magnesium plays a crucial role in keeping your body running smoothly. It helps regulate muscle contractions, supports your immune system, and aids in energy production at the cellular level.
The UK’s National Health Service (NHS) recommends a daily intake of at least 300mg for men. However, researchers in the latest study suggest higher levels, around 410-420mg daily, might offer additional benefits for muscle health and performance.
The Study: Examining Magnesium’s Role in Muscle Health
Researchers analyzed 20 studies to understand how magnesium supplementation influences skeletal muscle. They focused on areas like muscle growth, oxidative stress, and neuromuscular disorders.
Oxidative stress, caused by an imbalance between antioxidants and harmful free radicals, can contribute to muscle damage. Magnesium, the study found, helps combat this damage, protecting muscle tissue and enhancing recovery.
What the Researchers Found
1. Boosted Muscle Strength and Mass
Magnesium supplementation enhanced muscle mass, respiratory function, and overall strength in participants, particularly those with deficiencies or age-related muscle loss. It also lowered oxidative stress, helping muscle cells produce energy more efficiently.
2. Better Metabolism
Magnesium plays a key role in managing lipid, glucose, and protein metabolism. These metabolic processes provide the energy your muscles need to perform and recover.
3. Help for Neuromuscular Disorders
The mineral showed potential for reducing muscle damage and supporting repair, particularly in conditions like sarcopenia or other neuromuscular disorders.
4. Reduced Inflammation and Soreness
Athletes who took magnesium supplements experienced lower inflammation levels and faster recovery, with reduced muscle soreness after exercise.
Who Can Benefit from Magnesium Supplements?
While the study showed clear benefits for certain groups, not everyone will experience the same results.
- For those with low magnesium levels: Supplementing can help restore balance and improve overall health.
- For older adults: Magnesium may reduce age-related muscle loss (sarcopenia) when paired with regular exercise.
- For active individuals: Athletes or anyone training intensively might see faster recovery and better performance.
How to Supplement Magnesium Safely
Magnesium is available in several forms, including tablets, powders, and electrolyte drops. The study suggests aiming for 410-420mg per day for optimal benefits, though it’s essential to consult your doctor before starting any new supplement.
You can also increase magnesium naturally through foods like:
- Leafy greens (spinach, kale)
- Nuts and seeds (almonds, sunflower seeds)
- Fish (salmon, mackerel)
- Dairy products
Should You Take Magnesium for Muscle Gains?
Magnesium has a significant role in muscle health, from enhancing strength and mass to improving recovery and reducing inflammation. While it’s no replacement for regular resistance training, magnesium supplementation could offer an edge for those with lower levels or specific muscle health concerns.
Before adding a supplement to your routine, talk to your healthcare provider to ensure it’s right for your needs. Alternatively, incorporate magnesium-rich foods into your diet for a natural boost.
This mineral might just be the missing piece to help you push through plateaus and power up your performance.
