Buying Guide

Choose the right magnesium form

Magnesium glycinate is often gentler for sleep and calming effects, while citrate and oxide are more likely to support digestion and bowel regularity

Check dose per serving

Compare milligrams of elemental magnesium per serving to match your target intake and avoid unexpected under- or overdosing

Look for supporting ingredients

Products with added potassium or vitamin C can help specific needs like muscle relaxation or antioxidant support, depending on formulation

Consider delivery form and lifestyle

Powders and liquids allow flexible dosing and flavor options, capsules/tablets offer convenience for travel and consistent dosing

Assess allergen and diet labels

Choose gluten-free, vegan, or vegetarian capsules if you have dietary restrictions and confirm third-party testing or ingredient transparency
