Yes, tap water can be a source of magnesium, but the amount varies significantly by location, ranging from very low to potentially providing 30% or more of the daily need (DRI) if you drink enough, though it's often less impactful than food sources; it's best to check local water reports or rely on mineral-rich foods for consistent intake.
Assuming two liters of tap water are consumed daily, only four minerals provided more than 1% of the U.S. Daily Value (DV): copper, 10%; calcium, 6%; magnesium, 5%; and sodium, 3%.
Achieving 100% of the daily recommended magnesium intake can be accomplished by eating foods rich in magnesium, such as:
Your body needs magnesium to function normally. Symptoms of magnesium deficiency include low appetite, nausea or vomiting, muscle spasms or tremors and abnormal heart rhythms. A blood test or urine test can be used to diagnose magnesium deficiency.
Avocados: One whole avocado = 58 mg of magnesium. Bananas: One medium banana = 32 mg of magnesium. Papaya: One small papaya = 33 mg of magnesium. Blackberries: 1 cup = 29 mg of magnesium.
Gerolsteiner Sparkling Mineral Water contains more magnesium than most mineral waters with 108 mg per litre. Our easy-to-use Mineral Calculator provides more information and can be used to compare nearly 500 waters available worldwide.
To quickly increase magnesium levels, focus on magnesium-rich foods like dark leafy greens (spinach, kale), nuts (almonds, cashews, pumpkin seeds), seeds (chia, flax), legumes (beans, lentils), whole grains (quinoa, brown rice), and dark chocolate, while supplements or magnesium-fortified water can provide faster boosts if diet isn't enough, but always consult a doctor first.
Altered magnesium levels have been linked to inflammatory skin conditions, including atopic dermatitis (AD), psoriasis, and acne vulgaris (AV).
If you're not sure where to begin, magnesium glycinate is an excellent place to start for sleep and anxiety. For sharper thinking or brain-based anxiety, try magnesium L-threonate. And for calming both your mind and body, magnesium taurate offers a gentle, heart-centered approach.
But some foods and drinks can make it harder for your body to absorb magnesium or even increase magnesium loss, so timing and pairing matter.
Key takeaways: Water hardness refers to the mineral content in water, with hard water having more minerals and soft water having fewer minerals. There is no clear consensus on whether hard water or soft water is better for drinking, but soft water is gentler on the skin and hair.
Fresh water is usually dominated by calcium, while in alkaline water sodium is the main element. In most water bodies, magnesium concentration falls between 1 mg/L to 40 mg/L. The calcium to magnesium ratio in natural water has a certain relationship.
Electrolytes such as potassium, sodium, and magnesium help regulate everything from your kidneys to your heart function. If you consume too much water, there may not be enough of these electrolytes in your body to keep it functioning properly.
Severe visual loss and legal blindness, which may be caused by the induced hyperexcitability and toxicity of the NMDA receptors, have been observed in Mg-deficient (Mg-D) patients (12).
Magnesium levels naturally decline as we age, and this decline is associated with the formation of wrinkles and sagging skin. By replenishing magnesium levels, we can potentially slow down the aging process and maintain a more youthful appearance.
When taken in doses greater than 350 mg daily, magnesium is possibly unsafe. Large doses might cause too much magnesium to build up in the body, causing serious side effects including an irregular heartbeat, low blood pressure, confusion, slowed breathing, coma, and death.
For drinks high in magnesium, opt for mineral waters, fruit juices (especially orange, cherry, watermelon), plant-based milks (soy, almond), and homemade concoctions using raw cacao, coconut milk, or magnesium powders mixed with water or smoothies, with hot chocolate (made with raw cacao) and herbal teas (like nettle) also being good choices.
Bananas are the richest fruit in magnesium. If eaten dried, its magnesium content is higher. More generally, dried fruits such as figs, dates and apricots are an important source of magnesium. Recipe idea: Try a banana-spinach smoothie.
Food. Good sources of magnesium include green leafy vegetables, legumes, nuts, seeds, whole grains, and certain beverages. Magnesium may also be added to some breakfast cereals and other fortified foods.
Tap water can be a significant source of both magnesium and calcium. One recent study found that 2 liters of some municipal tap waters could provide up to 30% of the magnesium DRI (Daily Recommended Intake) for adults.

The group of green teas was the best source of phenolic compounds (110.73 mg/100 mL) and magnesium (1885 µg/100 mL) and was also characterised by the highest antioxidant activity (59.02%). This type of tea is a great contributor to the daily intake of the studied components.
