What is in BioMuscle XR?
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).
| Ingredient | Amount | % DV | Among products listing it |
|---|---|---|---|
| BioMuscle XR Proprietary Blend | 800 mg | ||
| L-Arginine Alpha KetoglutarateL-Arginine Alpha Ketoglutarate Note: 2-1 | in the blend, no amount given | ||
| L-Arginine | in the blend, no amount given | ||
| L-Arginine Hydrochloride | in the blend, no amount given | ||
| L-Citrulline | 5 mg | over 99% of 1,209 products listing citrulline give more (median 3 g). Per day at the most servings: 0.01 g. | |
| Dipotassium Phosphate | 4 mg | 0%* | The label names the compound (Dipotassium Phosphate); its amount is likely the compound's weight, not the potassium it holds, so it is not placed among other products. |
* % Daily Value computed from the printed amount and the FDA Daily Value (21 CFR 101.9); the label prints none for that row.

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:
- over 99% of the 1,209 products that print an amount of citrulline list more than its 0.005 g of L-citrulline (filed by NIH under citrulline) (median 3 g).
The NIH database records 1 to 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.
