Which drink has the most magnesium?

Magnesium is a critical mineral for energy production, muscle and nerve function, and bone health. While many people obtain magnesium from foods, beverages can be a convenient and effective source—ranging from mineral waters and vegetable smoothies to fortified plant milks and concentrated supplement drinks. This article summarizes which drinks tend to contain the most magnesium and how to evaluate options based on bioavailability, sugar content, and suitability for daily use.

Top beverage sources of magnesium

Liquid magnesium content varies widely by source and processing. At the higher end, fortified supplement drinks and powdered magnesium formulations typically deliver the largest single doses—often 200–400 mg per serving—using bioavailable forms such as magnesium citrate or bisglycinate. Natural options with notable magnesium include:

• High-mineral mineral waters: Certain European mineral waters can exceed 100 mg per liter; some brands explicitly list mineral composition on their labels.
• Concentrated green smoothies and vegetable juices: Drinks that blend spinach, chard, pumpkin seeds, nuts, or avocado can supply substantial magnesium, depending on portion size and ingredient ratios.
• Fortified plant-based milks: Many almond, soy, and oat milks are fortified to provide meaningful magnesium per serving (often 80–150 mg per 250 ml).
• Coconut water and electrolyte beverages: Moderate natural magnesium content (roughly 40–60 mg per cup for coconut water) and some sports drinks include added magnesium for rehydration.

Natural vs fortified/supplement drinks

Natural beverages offer the advantage of whole-food nutrient matrices and often bring other vitamins and phytochemicals, but they may provide lower magnesium per serving compared with fortified or supplement drinks. Fortified beverages and drinkable supplements are formulated to deliver targeted amounts, and when they use well-absorbed forms (citrate, bisglycinate) they can be most effective for correcting shortfalls.

How to choose the best magnesium drink

Consider these criteria:

• Elemental magnesium per serving: Compare labels to know how much actual magnesium you get.
• Form/bioavailability: Prefer citrate or bisglycinate for absorption and tolerability.
• Added ingredients: Watch for sugars, artificial additives, or allergens that may conflict with dietary goals.
• Use case: Hydration and mild replenishment (mineral water, coconut water) vs targeted supplementation (powders/drinks with 200+ mg).
