Lithium Deficiency: Symptoms, Causes, and Dietary Tips

Lithium is a trace mineral that occurs naturally in small quantities within water, soil, and specific food products. While minerals like iron and calcium have official recommendations regarding their optimal daily consumption levels, no such recommendation exists for lithium; hence, a "lack" of lithium has not been scientifically defined yet. Some scientists propose, however, that low environmental and dietary consumption of lithium could affect one’s mood and mental state, though further investigation is required.

The symptoms of low lithium consumption might be moodiness, irritability, problems with focus, fatigue, and an altered emotional state. One should keep in mind that these symptoms are rather non-specific, as they could be caused by many other medical or psychological issues.

Some of the causes associated with low levels of lithium may be eating foods from soils lacking in lithium, drinking water with low levels of lithium, restricted dieting, and geographical differences. To date, there is no laboratory test available or standardized criteria for diagnosing nutritional lithium deficiency.

It is essential to consume a healthy diet in order to ensure a good intake of trace minerals. Foods such as whole grain products, legumes, potatoes, tomatoes, cabbage, and some mineral drinking water all contain low amounts of lithium. Fruit and vegetables are essential for the intake of other minerals.

It is not recommended that people use lithium supplements to self-medicate or take any prescription forms of lithium because too much lithium can cause poisoning. People who notice signs such as mood fluctuations or neurological issues should see a healthcare professional to address any possible problems, which could include a lithium deficiency.
