What is in Pro-Rite?
Each row as the label prints it, per serving of 2 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).

| L-Proline | 500 mg | Higher than 51% of 387 products listing proline (median 487.5 mg). | |
| L-Lysineas Lysine MonohydrochlorideL-Lysine (from lysine monohydrochloride) | 500 mg | 40% of 1,250 products listing lysine give more (median 500 mg). |

Is that a lot?
