Vanadium

DESCRIPTION

Found in the body as well as in foods, vanadium is an ultra-trace mineral. While it is known to be essential for some animals, it has not been proven to be an essential mineral for humans.

FUNCTIONS

Vanadium may have a role in building bones and teeth. It may also be needed for normal growth, fertility, and lipid metabolism.

DEFICIENCY

Deficiency symptoms in animals requiring vanadium include growth retardation, bone deformities, and Infertility. Such deficiency symptoms have not been established in humans.

REQUIREMENTS

Less than 10 µg daily is the estimated requirement.

Average diet provides 15-30 mcg daily.

SUPPLEMENTAL USES

Type II diabetes:
One form of vanadium, vandyl sulfate, may help control glucose in individuals with non-insulin-dependent diabetes (1).

SAFETY

Safety information is limited. Synthetic forms of the mineral can be easily toxic. Long-term safety of large doses (100 mg) of vanadium has not been established. It is advised to exercise caution and moderation with use, and to seek medical supervision. Vanadium dust may be toxic to workers who are exposed to it. High blood levels of vanadium is associated with mani-depressive mental disorders, but this information is inconclusive (2).

INTERACTIONS AND CONTRA-INDICATIONS

Avoid taking vanadium with Chromium (including multi-mineral formulas featuring both minerals).
