What Bottled Water Has Silica for Optimal Nutrition?

November 1, 2025 •

4 min read

The median value of silica in groundwater is around 17 parts per million (ppm), but certain bottled mineral waters, often from volcanic regions, contain significantly higher levels. For individuals focusing on a specific nutrition diet, knowing what bottled water has silica can be a key part of a wellness strategy.

Quick Summary

Silica is a trace mineral present in many mineral waters, with some brands offering higher concentrations due to their natural sourcing. This guide explores which bottled waters are richest in silica, detailing the health benefits for skin, bones, hair, and detoxification. It also provides a comparison of popular brands and guidance on incorporating silica-rich water into your diet.

Key Points

Silica-rich brands: Fiji Water (93 ppm) and ACILIS by Spritzer (55.2 ppm) are known for their high silica content from natural spring sources.
Source matters: The silica content in mineral water varies significantly depending on the geological source, with volcanic and deep artesian sources yielding higher concentrations.
Boosts skin and hair: Silica promotes collagen production, which improves skin elasticity, and strengthens hair and nails, reducing brittleness.
Supports bones and joints: As a vital trace mineral, silica aids in calcium absorption, contributing to strong bones and supporting healthy connective tissues.
Aids in detoxification: Drinking silica-rich water can help the body flush out aluminum, a neurotoxin linked to cognitive decline.
Check the label: Always read the mineral analysis on the bottle to verify the specific silica content, as concentrations can vary between brands and even sources.

The Role of Silica in a Nutritious Diet

Silica, also known as silicon dioxide ($SiO_2$), is a compound found abundantly in the Earth's crust. It naturally makes its way into water as it filters through rock formations. For the human body, silica is a vital trace mineral, essential for various biological functions, even though it is not a daily requirement like calcium or magnesium. As we age, our body's silica levels naturally decline, potentially impacting bone density and the integrity of connective tissues. A silica-rich diet, including high-silica bottled water, can help supplement these levels and support overall health.

Which Bottled Waters Have High Silica Levels?

Many bottled mineral waters contain natural silica, but the concentration can vary dramatically depending on the source. Waters from volcanic areas and certain deep artesian aquifers typically have higher levels. Below is a list of some bottled water brands known for their higher silica content, along with an indication of their concentration. For specific and up-to-date levels, it is always best to check the product's label, as mineral compositions can fluctuate.

Fiji Water: Sourced from a remote artesian aquifer, Fiji Water is well-known for its soft, smooth taste, which is a result of its high silica content. Its analysis shows around 93 ppm of silica, making it one of the most accessible high-silica brands.
ACILIS by Spritzer: Sourced from a deep aquifer in the Malaysian rainforest, ACILIS reports a silica content of 55 mg/L. It is specifically marketed for its health benefits, including supporting detoxification of aluminum.
Volvic: This French mineral water contains a notable amount of silica, typically around 32 mg/L, making it a reliable source for daily intake.
Starkey Spring Water: A US-based spring water, Starkey boasts a high silica level, with a reported 58.9 mg/L.
Vichy Catalan: This Spanish mineral water is highly carbonated and rich in minerals, including a significant amount of silica, around 77.8 ppm.
Ferrarelle: Hailing from Italy, this naturally sparkling mineral water contains 81.1 ppm of silica.
Healsi: This Portuguese brand markets itself for its high silica content, around 74.4 mg/L, and its hydrating properties.

How Silica Benefits Your Health

Incorporating silica into your diet, whether through bottled water or other sources, offers several potential health advantages:

Promotes Healthy Skin, Hair, and Nails: Silica is crucial for collagen production, the protein responsible for skin elasticity and firmness. It helps your skin retain moisture and can reduce the appearance of fine lines and wrinkles. It also strengthens hair, preventing brittleness and thinning, and supports the growth of strong nails.
Supports Bone and Joint Health: Silica plays a role in enhancing calcium absorption, which is vital for bone mineralization. It helps maintain bone density and supports the formation of collagen for strong, flexible connective tissues and cartilage, which can help alleviate joint pain and inflammation.
Aids in Detoxification: Research has shown that consuming silica-rich water can help the body excrete aluminum, a neurotoxic metal, through the kidneys. This suggests a protective effect against conditions linked to aluminum accumulation, like Alzheimer's disease.
Boosts Cardiovascular Health: By strengthening blood vessels and muscle tissue, silica can contribute to a healthier cardiovascular system. Some studies suggest it can reduce cholesterol levels and the risk of atherosclerosis.
Strengthens the Immune System: Silica has an alkalizing effect on the body, which helps to support the immune system. It also helps in the production of antibodies, which are essential for fighting off infections.

Factors to Consider When Choosing Silica Water

While higher silica content is beneficial, it is not the only factor to consider when choosing bottled water. The overall mineral composition can affect taste and other health impacts. The source of the water is also important, as natural springs and artesian wells tend to yield a richer and purer mineral profile. Always check the label for a complete mineral analysis. For the most effective absorption, silica from natural mineral water, in the form of orthosilicic acid, is considered highly bioavailable.

Conclusion: Hydration with a Mineral Boost

For those looking to supplement their nutrition, knowing what bottled water has silica can be a valuable addition to a healthy lifestyle. While the average diet provides some silica, opting for a brand with a higher concentration can offer enhanced benefits for skin, hair, bones, and even detoxification. Brands like Fiji, ACILIS, and Volvic offer reliable and accessible options. As with any nutritional choice, integrating silica-rich water should be part of a balanced diet and healthy hydration routine. To delve deeper into the science behind silica's effects, particularly concerning aluminum detoxification, one can refer to the research by Professor Christopher Exley, an expert in the field.

Frequently Asked Questions

Yes, drinking water with elevated silica levels is generally considered safe. Health authorities have not set maximum allowable limits for silica in drinking water, and research suggests it is not harmful at typical concentrations. The body efficiently excretes any excess.

Silica naturally gets into water as it filters through underground rock formations, particularly those rich in quartz or other silicate minerals. This process is most pronounced in water from geothermal or volcanic regions, which is why brands sourced from these areas tend to have higher levels.

Consuming silica-rich water is linked to several benefits, including improved skin elasticity, stronger hair and nails, better bone and joint health by aiding calcium absorption, and supporting the body's detoxification process, particularly for aluminum.

Yes, most tap water contains some amount of dissolved silica, but typically at much lower concentrations compared to naturally sourced mineral waters from specific geological regions. The concentration varies widely depending on the local water source and geology.

There is no official Recommended Dietary Allowance (RDA) for silica. However, studies suggest an adequate intake could be between 10 and 25 mg per day for adults to achieve potential health benefits. Most people get this amount through diet, but silica-rich water can help ensure sufficient intake.

Yes, silica plays a role in bone mineralization and enhances the body's absorption of calcium. Some studies suggest it may be more important for bone strength than calcium supplementation alone, making it a valuable nutrient for preventing osteoporosis.

No, while Fiji Water is one of the most well-known silica-rich brands, many others have significant levels. Brands like ACILIS by Spritzer, Volvic, Vichy Catalan, and Starkey Spring Water also contain high concentrations, often sourced from volcanic or geologically active areas.
