Vanadium and your healthOne of the few somewhat obscured essential nutrients, vanadium (V), has relatively recently become recognized as essential to human health. Not much is known about its role in the body, but deficiency of this mineral may be a factor in some forms of spinal degeneration and ankylosing spondylitis18. It is suspected that it may be elevating muscle and liver glycogen levels, thus enhancing athletic performance.
However, significant longer-term supplementation is not advisable. There is evidence suggesting that excess vanadium can cause chemical imbalances in the body, resulting in body aches, arthritis, weakened immune system, gastrointestinal and other symptoms.
High vanadium levels can also negatively affect individuals suffering from bipolar order or manic depression.
There is no official DRI (Dietary Reference Intakes, the most recent set of dietary recommendations set by the government) for vanadium. Its insufficient intake/deficiency are not considered to be likely, in general. However, exceptions are possible, and likely to be found primarily in individuals with high intake of vanadium antagonists and inhibitors (sugar, chromium, calcium, sodium).
Suggested adequate daily intake for vanadium is 0.1mg, with short-term therapeutic doses of up to 100mg a day.
Natural vanadium food sources are vegetable oils, fats, seafood, and others.
