Phosphorus supplements

Half of the 3,786 phosphorus supplements in the NIH label database that print an amount list 90 mg or less per serving; the middle half list 45 mg to 200 mg, and 1 in 1,245 of the 3,735 with a plausible amount give more than the adult upper limit at the most servings their labels direct (DSLD version 9.4.0, January 2026).

How much phosphorus do supplements contain?

The median product lists 90 mg per serving. One in ten lists 20 mg or less, one in ten 350 mg or more. The amount printed most often is 20 mg (235 products).

How do the amounts compare with the Daily Value and the upper limit?

The FDA Daily Value for phosphorus is 1,250 mg (adults and children 4 and older). The median product gives 7% of it per serving; the 90th percentile 28%.

The adult Tolerable Upper Intake Level is 4,000 mg a day (total intake from food, water and supplements). At the most servings their labels direct, 3 of the 3,735 products with a plausible amount (0.1%) give more than that from the supplement alone (what counts as plausible).

The upper limit is for total intake from food, water and supplements unless stated, and does not apply under medical supervision. A label amount is what the maker printed. This is data, not advice: the NIH ODS fact sheets explain what each nutrient does.

Which products list the most phosphorus?

On-market products, per serving, with a plausible amount: the rule leaves out likely entry slips, such as an amount far beyond every other label with no %DV or strength on the label to back it (each product page still shows its own amount, marked).
