Magnesium
What to Love
It’s one of the most well-tolerated supplements with a long list of subtle benefits. Some women notice immediate improvements in sleep or mood; others use it for muscle or migraine support. The key is picking the right form and dose.
How it Works
Start with 200–400mg of magnesium glycinate at night for sleep/mood, or citrate for digestion. Always check form and fillers.
Magnesium supports muscle relaxation, nerve function, and hormone metabolism. Deficiency may worsen anxiety, insomnia, or cramping during perimenopause.
Magnesium plays a key role in hundreds of cellular processes—including those tied to mood, muscle relaxation, and sleep quality. It may be especially helpful for women navigating hormonal turbulence, and different forms work differently (e.g. glycinate for anxiety/sleep, citrate for digestion).
When to Avoid
Avoid high doses if you have kidney disease; may cause loose stools in some forms
Possible Side Effects
Loose stools (especially with oxide or citrate), mild stomach upset
