Most people focus on training and protein when trying to build muscle. But a study published in May 2025 found something important that often gets missed.
Magnesium and zinc directly impact muscle growth, strength, and how well the body moves.
The study used a method called Mendelian randomization. That means it didn’t just look at trends. It tested whether people with higher genetic levels of certain nutrients actually had better muscle health. And they did.
People with higher magnesium levels had more lean muscle and better muscle retention.💪
People with higher zinc levels had faster walking pace and were more physically active. 🏃🏃♀️
Omega-3s showed a complex result. The study found a link between higher omega-3 levels and lower lean muscle mass. That finding needs more research. But omega-3s are still known to support heart, brain, joints, and overall inflammation.
The key point is this: you don’t need a genetic test. Whether your levels come from your genes or your diet, the impact is the same. You can raise them through food.
Start with magnesium-rich foods like leafy greens, pumpkin seeds, almonds, bananas, whole grains, and dark chocolate.
For zinc, include beef, chicken, eggs, chickpeas, lentils, and h**p seeds.
Low magnesium or zinc can leave you feeling tired, slow to recover, and stuck with poor progress. If that sounds familiar, these nutrients are worth a closer look.
Training and protein still matter, but they’re not the whole picture. The study shows that supporting your body with the right nutrients makes a real difference.
This is one of those cases where small changes in what you eat can lead to better performance, better recovery, and more results. Simple, practical, and backed by research.
