Lithium – The silent hero in the brain

Battery or brain booster?
If the word "lithium" immediately brings to mind smartphone batteries, that's no surprise. But you should definitely rethink that. Because what few people know is that lithium is not only a fuel for technology, but also a fascinating nutritional element with superpowers for the brain .

Welcome to a new exploration of the universe of underappreciated micronutrients. Today we're taking a closer look at lithium—and what we discover could change your perspective on this tiny element forever.

🧠 Lithium loves your brain

Lithium occurs naturally—in soil, plants, and drinking water. And also in your body—at least in trace amounts. But these very trace amounts could be a key to better mental health and clarity.

🧬 Lithium and Alzheimer's: The hot lead

Researchers discovered that in regions with higher lithium levels in drinking water, the rate of Alzheimer's and dementia is significantly lower . Why? Lithium appears to inhibit the formation of toxic amyloid plaques in the brain – these protein clumps are considered a contributing factor to Alzheimer's.

🔧 Cell protection and repair

Lithium activates certain enzymes (e.g., GSK-3β inhibitors) that reduce inflammatory processes , protect cells , and promote brain regeneration . And that's exactly what we need—especially in a world full of overstimulation, stress, and constant digital bombardment.

😌 Microdose, maximum effect?

While psychiatric medications rely on high doses of lithium, new studies show that even microdoses of between 0.3 and 5 mg daily can be effective – without side effects . They have a mood-stabilizing effect, reduce anxiety, promote better sleep, and can even keep brain cells active.

🧪 Food, water, supplement?

Lithium is natural—not a synthetic invention. Some of it can be found in foods like grains, potatoes, and mineral water. However, the concentration varies greatly depending on soil conditions. Those who want to play it safe can supplement their intake with gentle dietary supplements.

🕵️ Conclusion: Not just made for batteries

Lithium is a true insider tip in the field of cognitive health. It works quietly and discreetly – without hype, but with plenty of substance. For anyone who wants to protect their brain and maintain long-term vitality, a closer look at this underrated trace element is worthwhile.

Because sometimes the greatest treasure is not the loudest one – but the one that does its work inconspicuously.

PS:

💧 Why is lithium allowed in medicinal waters?

Medicinal and mineral waters are considered natural foods. Their mineral content, including lithium, comes from geological sources and is not artificially added. Such waters are considered traditionally safe because they have been consumed for centuries. They may be sold in Switzerland and the EU as long as they meet legal requirements. FSVO

💊 Why is lithium banned in dietary supplements?

Lithium is not included in the list of permitted minerals for food supplements in EU Directive 2002/46/EC. Therefore, it is not approved as a food supplement in the EU and Switzerland, which adhere to this directive. Products containing lithium are considered unmarketable.

⚖️ Conclusion: Naturally allowed, artificially forbidden

The difference lies in the formulation: Naturally occurring lithium in medicinal waters is permitted, while added lithium in dietary supplements is prohibited. This is based on different legal classifications and safety assessments.
