Vitamin B6 supplements

Half of the 15,277 vitamin B6 supplements in the NIH label database that print an amount list 6 mg or less per serving; the middle half list 2 mg to 20 mg, and 1 in 56 of the 15,130 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 201 products whose only supplement ingredient is vitamin B6 list a median of 100 mg, and 15% of them give more than the upper limit.

How much vitamin B6 do supplements contain?

The median product lists 6 mg per serving. One in ten lists 1 mg or less, one in ten 50 mg or more. The amount printed most often is 2 mg (2,019 products).

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

The FDA Daily Value for vitamin B6 is 1.7 mg (adults and children 4 and older). The median product gives 353% of it per serving; the 90th percentile 2941%.

The adult Tolerable Upper Intake Level is 100 mg a day (total intake from food, water and supplements). At the most servings their labels direct, 268 of the 15,130 products with a plausible amount (1.8%) 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 forms of vitamin B6 do labels name?

Pyridoxine hydrochloride is the form named most often: 11,242 of the 15,644 vitamin B6 products (72%), ahead of pyridoxal 5-phosphate (P5P) (2,275, 15%). A product naming two forms counts in both; the table below gives every form.

• Pyridoxine hydrochloride
• Pyridoxal 5-phosphate (P5P)

Which products list the most vitamin B6?

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).
