Mineral Water: Potential Health Benefits And Side Effects
Mineral water is obtained from natural springs and underground reservoirs. It is rich in essential nutrients and said to possess some therapeutic properties.
It contains calcium, magnesium, potassium, and sodium (1). Thus, it is claimed to provide some unexpected health benefits. Drinking mineral water may promote bone, digestive, and heart health, and lower blood pressure.
In this article, we talk about the difference between mineral water and tap water, and the potential health benefits and side effects of mineral water.

Mineral Water Vs. Regular Water
I. Mineral Water
Minerals that are often present in mineral water include:
- Calcium
- Chlorine
- Phosphorus
- Magnesium
- Potassium
- Sodium
- Sulfur
Listed above are some of the macronutrients that are essential for performing bodily functions such as protein synthesis, bone formation, cartilage formation, etc. (3).
Besides some micronutrients, trace elements are essential for some biological functions such as hormone synthesis, enzyme production, prevention of tooth decay, etc. (3).
- Cobalt
- Iron
- Chromium
- Copper
- Iodium
- Fluorine
Unlike normal tap water, mineral water is usually bottled at the source in plastic or glass bottles. Some people prefer mineral water due to its therapeutic value. However, mineral water may undergo some processing to remove bacteria or toxic substances (4). Daily intake of mineral water is essential to maintain body water equilibrium (3).
II. Tap Water
Before reaching households, tap water undergoes a chemical disinfection process in the water treatment plant. The clean water then gets delivered through the underground piping system. However, some minerals in the tap water can corrode pipes and pollute drinking water.
In the U.S., tap water must meet the Safe Drinking Water Act standards established by the Environmental Protection Agency (EPA) (5).
Now that you know the difference between mineral water and tap water, let’s check out the health benefits of mineral water!
6 Health Benefits Of Mineral Water
1. A Source Of Magnesium
Depending on the source, the amount of magnesium in mineral water may vary. The Recommended Dietary Allowances (RDAs) for magnesium are as follows (6):
- 310-320 mg for adult women
- 350-400 mg for pregnant women
- 310-360 mg for lactating women
- 400-420 mg for adult men
Magnesium deficiency may cause symptoms such as anxiety, irritability, fatigue, muscle weakness, tremors, and vertigo. In severe cases, it can also lead to seizures, hearing loss, migraines, osteoporosis, and irregular heartbeat (7).
2. May Help Lower Blood Pressure
A study conducted by Göteborg University (Sweden) found that drinking mineral water may help lower blood pressure in people with elevated blood pressure (11).
A study conducted on 70 people with borderline hypertension also found that drinking 1 litre of mineral water per day lowered their blood pressure (11).
However, more studies are required to understand the role of drinking mineral water in blood pressure management.
3. Promotes Bone Health
A study conducted by the Saxon Balneology and Rehabilitation Medicine Research Institute found that bioavailability of calcium from mineral water is comparable to (and could even be better) than from dairy products (13), (14). Another study conducted on postmenopausal women found that regular intake of calcium-rich mineral water increases the bone mineral density (15).
Furthermore, controlling magnesium homeostasis may help maintain bone integrity (16).
4. Improves Digestive Health
5. May Improve Heart Health
Another study conducted on postmenopausal women found that the intake of carbonated mineral water intake decreases total cholesterol and LDL-cholesterol levels, which reduces the risk of cardiovascular diseases (21). The magnesium levels in drinking water are also said to be inversely associated with coronary heart disease mortality (22).
However, more long-term studies are required to understand how drinking mineral water promotes heart health.
6. May Regulate Body Fat
Now that you know all about the health benefits of mineral water, let’s check out how it benefits your skin.
Is Mineral Water Good For Your Skin And Face?
Mineral water may be a fresh source of skin-friendly silica particles. Silica is great for the skin. It triggers the production of collagen in your skin. Increased collagen formation reduces wrinkles, dark spots, and dullness. Furthermore, silica deficiency leads to skin ageing (24). Hence, mineral water may be a good source of skin health.
However, more long-term studies are required to understand this benefit of mineral water.
Though mineral water is generally safe for consumption, it does have a few side effects that you need to keep in mind. Check them out in the next section.
What Are The Side Effects Of Mineral Water?
Many studies focused on bottled mineral water are about the migration of chemicals from plastic bottles to water (25). A study conducted on mice found that microplastics consumed through water can accumulate in the body and cause inflammation (26).
The carbonic acid present in carbonated mineral water can cause bloating (27). Mineral water contains fewer microbes when compared to normal tap water. Thus, it does not undergo the disinfection process (unlike tap water) and contains microbes. It is also sometimes enriched with carbon dioxide (28).
Plastic Toxicity
Though the microplastics in bottled water do not raise a safety concern, more research is required in this area (29).
Carbonated Water Damages Teeth
Carbonated water is more acidic than regular tap water. A study conducted in Korea found that carbonated water manufactured by a soda carbonator reduces enamel hardness (31). But, it has a smaller impact on teeth than drinking soda (32).
Environmental Concerns
Conclusion
From improving bone density to promoting digestive health, mineral water is said to have many health benefits. However, it is also associated with plastic toxicity (due to the microplastics in bottles) and enamel erosion. Therefore, use your discretion before you drink any type of water.
