Sourcing the Highest Lithium Content Mineral Waters
The concentration of naturally occurring lithium in mineral water is not uniform; it is a direct result of the water's path through the earth's crust, particularly through granite or volcanic rock formations. This geological process enriches the water with a unique blend of minerals. Several brands stand out for their particularly high lithium content, which has been documented in scientific studies and analyses.
Top European and American Brands
Vidago (Portugal): This Portuguese mineral water is one of the most lithium-rich known, with concentrations exceeding 2200 µg/L in some analyses. Sourced from Hercynian granitic rocks in northern Portugal, Vidago is a naturally carbonated, highly mineralized water rich in sodium bicarbonate.
Perling (Germany): A study of various German beverages found that Perling mineral water from the Tiefen spring contained a significant lithium concentration of 1611.9 µg/L, placing it among the highest-potency waters.
Malavella, San Narciso, and Vichy Catalan (Spain): Sourced from the Caldes de Malavella region of Spain, these thermal waters are highly notable for their lithium levels. Analyses have shown concentrations as high as 1250 µg/L for Malavella and 1070 µg/L for both San Narciso and Vichy Catalan. They are characterized by their natural carbonation and high mineralization.
Lithia Spring Water (USA): Bottled since 1888 from a spring in Lithia Springs, Georgia, this American brand is known for its naturally occurring lithium carbonate. It contains approximately 500 mcg (µg) of lithium per liter and has a history tied to health tonics.
Other Notable Brands with Trace Lithium
While not as high in concentration as the top-tier brands, several other widely available mineral waters contain detectable, albeit lower, levels of lithium:
- Gerolsteiner (Germany): A sparkling water with a medium lithium concentration, listed at 209.7 µg/L in one study. Wikipedia cites an analysis listing 0.13 ppm (equivalent to 130 µg/L).
- 5100 Tibet Spring (China): Documented with a lithium content of 0.25 ppm (250 µg/L).
- Nongfu Spring Lithium Water (China): Contains over 0.2 ppm (200 µg/L).
- San Pellegrino (Italy): A well-known sparkling water containing trace amounts of lithium, around 0.12 ppm (120 µg/L).
Comparison of High-Lithium Mineral Waters
To put the concentrations into perspective, the following table compares several mineral water brands based on their reported lithium content. Note that figures can vary slightly between batches and studies.
| Brand | Source | Approx. Li Concentration | Notes |
|---|---|---|---|
| Vidago | Portugal | >2200 µg/L | One of the highest documented, naturally carbonated. |
| Perling | Germany | ~1612 µg/L | High concentration from the Tiefen spring. |
| Malavella | Spain | ~1250 µg/L | Thermal water, naturally carbonated. |
| Vichy Catalan | Spain | ~1070 µg/L | Thermal water, naturally carbonated. |
| Lithia Spring Water | USA | ~500 µg/L | Natural lithia water from a historic spring. |
| 5100 Tibet Spring | China | ~250 µg/L | Sourced from the Tibetan Plateau. |
| Gerolsteiner | Germany | ~210 µg/L | Widely available, medium lithium level. |
| San Pellegrino | Italy | ~120 µg/L | Popular sparkling water with low-level lithium. |
Potential Health Implications of Trace Lithium
The presence of trace amounts of lithium in certain mineral waters has sparked interest in its potential health effects, particularly concerning mental well-being. It is crucial to distinguish between the microdoses found in mineral water and the much higher, pharmacologically managed doses used to treat conditions like bipolar disorder.
Research has explored the association between low-level dietary lithium intake and several outcomes:
- Mental Health: Some ecological studies have shown an inverse correlation between naturally occurring lithium levels in tap water and suicide rates in local populations. A 2020 study compiling data across multiple countries noted this association but acknowledged more research is needed.
- Neuroprotection: Emerging research suggests that low-dose lithium might have neuroprotective effects, potentially improving emotional regulation and offering protection against conditions like dementia. Animal models have shown that trace lithium may increase brain-derived neurotrophic factor (BDNF), a protein vital for neuroplasticity.
- Safety Considerations: The scientific community maintains caution and emphasizes that the effects of chronic low-dose exposure are not yet fully understood. Many studies call for more comprehensive research into the mechanisms and benefits of natural lithium intake, particularly through controlled community trials.
It is important to remember that lithium-rich mineral waters may contain other minerals, such as sodium or fluorine, at concentrations that can limit their recommended consumption for some individuals. As always, consulting a healthcare professional is advised before making any significant dietary changes.
How is Lithium Content Measured and Regulated?
The determination of lithium concentration in mineral water involves sophisticated laboratory techniques, such as inductively coupled plasma-mass spectrometry (ICP-MS). Unlike major minerals like calcium or magnesium, lithium is often not listed on standard bottle labels, particularly in trace amounts.
Key measurement points:
- Precision: Analytical labs use advanced spectrometry to detect and quantify even trace amounts of lithium with high precision.
- Regulation: Currently, neither European directives nor Spanish regulations define a concentration limit for lithium in drinking water, which explains the wide variation found in different brands.
- Bioavailability: Studies show that lithium from mineral water is highly bioavailable, meaning the body can readily absorb it.
This lack of mandatory labeling and wide variation underscores the importance of relying on scientific studies or direct manufacturer data for specific information on a water's lithium content.

Conclusion
In summary, for those wondering what mineral water is high in lithium, the answer lies in specific brands sourced from geologically unique areas, primarily in Europe and the USA. Brands like Vidago, Perling, Malavella, and Vichy Catalan boast the highest concentrations, while others like Lithia Spring Water and Gerolsteiner contain moderate to low but still notable levels. While research suggests potential mental wellness benefits from trace lithium, this should not be confused with therapeutic doses. The bioavailability of lithium from water is high, making these waters a potential source of this trace element, though consumers should be mindful of other mineral contents, such as sodium, and consider individual health needs.
