FAQ: Which magnesium is best for perimenopause?

There's no single "best" type—it depends on your symptoms. Many women trying magnesium for sleep or anxiety start with glycinate. For constipation, citrate is often chosen. For brain fog, some prefer threonate. Track your specific symptoms to see what helps.

FAQ: How much magnesium is common in supplements?

The recommended daily allowance for adult women is 310-320mg. Many supplements provide 200-400mg. Always discuss supplementation with your healthcare provider, especially if you have kidney issues or use medications.

FAQ: How long before I notice effects?

Some effects (like bowel changes with citrate) happen quickly. Others (like improved sleep or reduced anxiety) may require 2-4 weeks of consistent use. Track from day one to catch subtle changes.
