The label names the compound (Vanadyl Sulfate); its amount is likely the compound's weight, not the vanadium it holds, so it is not placed among other products.

Is that a lot?

The rows in the top or bottom tenth of the products that list the same ingredient, and any above the adult upper limit at the most servings a day the directions give:

  • Its 65 mg of thiamin is higher than 92% of the 9,830 thiamin products that print an amount; 818 list more.

  • At 2 servings a day, the most its directions give, the label lists 400 mg of magnesium, 1.1 times the adult Tolerable Upper Intake Level.
  • 87% of the 933 products that print an amount of acetyl L-carnitine list more than its 50 mg of acetyl L-carnitine (median 500 mg).

The NIH database records 2 servings a day from the label's directions; its % Daily Values are for adults and children 4 or more years of age. The directions as printed are further down this page.

The Tolerable Upper Intake Level is the most of a nutrient per day, from food, water and supplements together, that is likely to pose no risk for almost all adults (Institute of Medicine, 2011). It does not apply under medical supervision. This page compares labels; it is not medical advice.
