How to Get the Most From Your Magnesium Supplement
Take your magnesium supplement with food to minimize potential digestive upset. Splitting your daily dose into two smaller servings, such as morning and evening, may improve absorption for some individuals. Consistent daily intake is more effective than sporadic use; aim for daily use for at least 3-5 days to notice effects.
Combine magnesium supplementation with a diet rich in magnesium-containing foods like leafy greens, nuts, and seeds. Ensure adequate hydration throughout the day, as water helps with nutrient absorption and overall bodily functions. Consult your healthcare provider for personalized dosage recommendations, especially if taking for more than 3 days.
