Report 2 indicates it may help diabetes

1. Wickipeda "Vanadium (pronounced /v?'ne?di?m/) is the chemical element with the symbol V and atomic number 23. It is a soft, silvery grey, ductile transition metal. The formation of an oxide layer stabilizes the metal against oxidation. Andrés Manuel del Río discovered vanadium in 1801 by analyzing the mineral vanadinite, and named it erythronium. Four years later, however, he was convinced by other scientists that erythronium was identical to chromium. The element was rediscovered in 1831 by Nils Gabriel Sefström, who named it vanadium after the Norse goddess of beauty and fertility, Vanadis (Freya). Both names were attributed to the wide range of colors found in vanadium compounds. The element occurs naturally in about 65 different minerals and in fossil fuel deposits. It is produced in China and Russia from steel smelter slag; other countries produce it either from the flue dust of heavy oil, or as a byproduct of uranium mining. It is mainly used to produce specialty steel alloys such as high speed tool steels. The compound vanadium pentoxide is used as a catalyst for the production of sulfuric acid. Vanadium is found in many organisms, and is used by some life forms as an active center of enzymes. (1)

Vanadium(III, IV, V)-chlorodipicolinate (dipic-Cl) complexes, including H[V(III)(dipic-Cl)(2)] . 5H(2)O (V(3)dipic-Cl), V(IV)O(dipic-Cl)(H(2)O)(2) (V(4)dipic-Cl) and K[V(V)O(2)(dipic-Cl)] (V(5)dipic-Cl), were prepared with the indicated oxidation states. Our aim was to evaluate the anti-diabetic effects of V(3)dipic-Cl, V(4)dipic-Cl and V(5)dipic-Cl in streptozotocin-induced diabetic rats. Vanadium complexes were orally administered to diabetic rats at concentrations of 0.1-0.3 mg/ml in the drinking water. We found that vanadium-chlorodipicolinate (V-dipic-Cl) complexes at the concentration of 0.1 mg/ml did not exhibit blood glucose-lowering effects when administered to diabetic rats for 20 days. However, the levels of fasting blood glucose in diabetic rats were decreased after treatment with 0.3 mg/ml of V(4)dipic-Cl and V(5)dipic-Cl complexes for the following 20 days. Although administration of both V(4)dipic-Cl and V(5)dipic-Cl significantly lowered diabetic hyperglycemia, the vanadium intake from administration of V(4)dipic-Cl is nearly 1.5-fold greater compared to that of V(5)dipic-Cl. Treatment with the H(2)dipic-Cl ligand and all three V-dipic-Cl complexes significantly lowered serum cholesterol, while administration of the V(5)dipic-Cl complex lowered serum cholesterol significantly more than administration of the ligand alone. Treatment with ligand alone did not have an effect on serum triglyceride, while administration of the V(4)dipic-Cl and V(5)dipic-Cl significantly lowered the elevated serum triglyceride associated with diabetes. Oral administration of the ligand and all V-dipic-Cl complexes did significantly lower diabetes elevated serum alkaline phosphatase. Treatment with H(2)dipic-Cl ligand and V(4)dipic-Cl and V(5)dipicCl significantly lowered diabetes elevated aspartate amino transferase. These results indicate that the health of the treated animals did not seem to be further compromised compared to that of diabetic animals. In addition, oral administration of H(2)dipic-Cl, V(3)dipic-Cl, V(4)dipic-Cl and V(5)dipic-Cl did not alter diabetic serum creatinine and blood urea nitrogen levels, suggesting no significant side effects of vanadium treatment on renal functions at the dose of 0.3 mg/ml in diabetic rats. The results presented here suggest that the anti-diabetic effects of treatment with V-dipic-Cl complexes were likely associated in part with the oxidation state of vanadium.
