What is in Blue Cycle?
Each row as the label prints it, per serving of 3 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:
- 94% of the 1,778 products that print an amount of beta-alanine list more than its 0.6 g of CarnoSyn (filed by NIH under beta-alanine) (median 2 g).
The NIH database records 2 to 4 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.
