How many Canadian vitamin B6 supplements recommend more than the US limit?

1,469 of 10,800 Canadian-licensed products (14%) recommend a daily amount of vitamin B6 at or over the NIH adult upper limit of 80 mg, and 2,931 (27%) recommend half the limit or more. The median licence recommends 15% of the limit at its highest dose. These are label facts, not a statement that any product is unsafe.

Not medical advice. This page compares what a Canadian licence authorises a company to recommend with a US population intake limit. It does not say any product is safe or unsafe, it does not say anyone takes that amount, and it gives no dose recommendation. Ask your pharmacist or doctor about your own supplements.

What does the licence data show for vitamin B6?

23,253 Canadian licences list vitamin B6; 10,800 have a recommended adult dose that can be read as a number of tablets or capsules a day. The US limit used is 80 mg a day for adults (14-18 years), which the NIH sets for total intake.

Measure	Licences
List vitamin B6	23,253
Could be checked	10,800
Half the limit or more	2,931 (27%)
At or over the limit	1,469 (14%)
Share of limit, 90th percentile	125%

3 licences with a share above ten times the limit are counted above but not used for the median or 90th percentile; they are more often a data-entry or unit issue in the licence record.

Why could some vitamin B6 licences not be checked?

A licence cannot be checked when its recommended adult dose is a liquid or powder amount, is not stated per day, is missing, or lists an amount in a unit the check cannot read. 12,453 licences listing vitamin B6 fall in these groups.

Reason	Licences
dose unit is not a countable dosage unit	7,973
frequency is not stated per day	2,466
no adult dose	1,639
dose or frequency is missing	351
no recommended dose on the licence	13
ingredient amount or unit not readable	11
