Magnesium is one of those minerals that quietly does a lot behind the scenes, especially when it comes to your muscles.
Calcium helps your muscles contract, while magnesium helps them relax. So if your magnesium levels are on the lower side (or your body is under more stress and needs more), you might notice things like tightness, tension or even cramps.
Of course, it’s not just about magnesium. Muscle tension can also be influenced by things like stress, posture, inflammation, and how much (or how little) you’re moving. Magnesium can definitely help support your nervous system and muscle function but it’s just one piece of the puzzle.
It can be especially helpful during perimenopause too. As hormones start to shift, many women notice changes in sleep, mood and stress tolerance. Magnesium can support relaxation, help with sleep quality, and may take the edge off things like muscle tension and heightened stress responses during this time.
Some signs that might be linked to low magnesium include:
• Muscle cramps or tightness
• Eye twitching
• Headaches
• Trouble sleeping
• Feeling more stressed or reactive
• Constipation
The tricky part? A lot of people aren’t getting enough magnesium from their diet. It’s mainly found in foods like leafy greens, nuts, and seeds ... and most adults aren’t eating enough veggies each day to meet their needs.
It doesn’t have to be complicated though. Small, consistent changes can really add up over time.
