What is in Cal-Mag Zinc?

Each row as the label prints it, per serving of 4 capsules. The capsule beside an amount places it among every product in the NIH database that lists the same ingredient: the bar is the middle half of their amounts, the line in it the median, the whiskers the 10th and 90th percentiles; the green tick is the FDA Daily Value and the red dashed tick the adult upper limit (IOM).

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 1,000 mg of calcium is higher than 95% of the 17,831 calcium products that print an amount; 314 list more.
  • At 1 serving a day, the most its directions give, the label lists 500 mg of magnesium, 1.4 times the adult Tolerable Upper Intake Level.
  • At 1 serving a day, the most its directions give, the label lists 50 mg of zinc, 1.3 times the adult Tolerable Upper Intake Level.
  • 88% of the 914 products that print an amount of betaine hydrochloride list more than its 10 mg of betaine HCl (filed by NIH under betaine hydrochloride) (median 50 mg).

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.
