Could Colloidal Vanadium reduce risk of diabetes?
Vanadium, a trace mineral, named after the Vanadis Scandinavian goddess of beauty and fertility, was used in the last century by French physicians as a treatment for diabetes and fatigue. Its popularity spread to North America, where it was used for hardening of the arteries. Once insulin was discovered, however, the use of this trace mineral dwindled because it can also be quite toxic in high doses.
Vanadium was declared an essential nutrient in 1971.
Recent studies have found Vanadium may improve the body's response to insulin, which is important for preventing insulin resistance, a pre-diabetic condition. Some individuals have gone so far as to suggest that vanadium deficiency may be directly linked to the development of insulin resistance.
Benefits of Colloidal Vanadium.
Vanadium is involved in glucose, cholesterol, and bone metabolism. It may act independently from insulin in lowering glucose levels. It has also been found to suppress cholesterol synthesis in the livers of young people who have higher cholesterol levels. Trials in adults with higher cholesterol failed to reduce levels.
Over the last few years, vanadium has garnered attention for its potential to improve diabetes. Several animal and limited human studies testing this relationship have taken place, with promising results. On one study a combination of vanadium and insulin-regenerated beta cells (which make insulin) and relieved diabetes in insulin-dependent diabetic rats during a year of treatment and after treatment ended. Those rats that were given only insulin did not experience these benefits.
Vanadium has proven therapeutic in clinical studies with patients with type 1 diabetes and in others with type 2 diabetes, noted the authors of recent review published in The Journal of Complementary Medicine. The mineral is considered as “insulin mimic”,in that it can partially substitute for insulin and help metabolize blood sugar.
Vanadium initiates an increase in the contractile force of the heart. Several studies indicate that it may have anticancer properties in the mammary glands of mice. Vanadium also appears to be involved in the mineralization of bone and teeth.
Vanadium has been shown to lower growth of human prostate cancer cells in tissue cultures, and to reduce bone cancer and liver cancer in animals.
Vanadium Deficiency signs and symptoms:
Dosages high than 250 micrograms per day of vanadium may be very dangerous. Symptoms of toxicity in animals include suppression of the immune system, destruction of red blood cells. This may be due to the type of vanadium used, however.
Human studies have not yet produced the same serious side effects. However, high doses over a long period of time have produced diarrhea and abdominal cramps. In addition, high doses of vanadium may deplete vitamin C.
Vanadium appears only in small quantities in food. The richest sources are certain spices, such as dill seeds, parsley, and black pepper. Mushroom, shellfish, and grains also contain fairly high levels. Lower quantities are found in meat, fish, and poultry.
