What is in Prime Test?
Each row as the label prints it, per serving of 2 caplets. 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?
Every amount on this label with a position sits within the middle 80% of the products that list the same ingredient; 8 ingredients sit inside a blend, so their amounts cannot be compared.
The NIH database records one serving a day from the label's directions; its % Daily Values are for adults and children 4 or more years of age.
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.
