What is in Cal-6+Mg.?

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).

  • 93% of the 1,250 products that print an amount of lysine list more than its 29 mg of L-lysine (filed by NIH under lysine) (median 500 mg).
