Vanadyl Sulphate

What is it? Vanadium is a trace element that appears to be essential for human health, although its exact role remains poorly understood. Vandyl sulphate is simply a well-absorbed form of vanadium.

How does it work? Advocates claim that like chromium, vanadium can up- regulate the insulin system, thereby helping the body to absorb glucose and amino acids more efficiently.

How strong is the evidence that it does what it's claimed to do? Very weak. The few scientific studies that have been carried out on vandyl sulphate supplementation have shown little or no benefit. Another one to leave behind on the shelf!
