Its current label entered the NIH Dietary Supplement Label Database on September 24, 2019.
What is in FBlock?
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 |
|---|---|---|---|
| Vitamin Cas Ascorbic Acid | 100 mg | 167% | 50% of 18,583 products listing vitamin C give more (median 100 mg). Per day at the most servings: 300 mg. |
| ChitosanChitosan (Form: Marine Fiber concentrate) | 1,000 mg | 10% of 77 products listing chitosan give more (median 1 g). Per day at the most servings: 3 g. | |
| Lipase | Lipase Note: 300 LU | ||
| Calcium Sulfate | 150 mg | 12%* | The label names the compound (Calcium Sulfate); its amount is likely the compound's weight, not the calcium it holds, so it is not placed among other products. |
| Vegetable Cellulose | 100 mg |
* % 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?
Every amount on this label with a position sits within the middle 80% of the products that list the same ingredient; 1 ingredient sits inside a blend, so their amounts cannot be compared.
The NIH database records 1 to 3 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.
