Boron supplements

Half of the 3,339 boron supplements in the NIH label database that print an amount list 1 mg or less per serving; the middle half list 0.3 mg to 2 mg, and 1 in 302 of the 3,322 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). The 38 products whose only supplement ingredient is boron list a median of 3 mg, and 1 in 38 of them give more than the upper limit.

How much boron do supplements contain?

The median product lists 1 mg per serving. One in ten lists 0.15 mg or less, one in ten 3 mg or more. The amount printed most often is 1 mg (708 products).

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

The adult Tolerable Upper Intake Level is 20 mg a day (total intake from food, water and supplements). At the most servings their labels direct, 11 of the 3,322 products with a plausible amount (0.3%) 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 boron?

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).
