Pyridoxine Dosage

In order to help ensure safe use of pyridoxine, doses should not exceed the Recommended Dietary Allowances (RDAs). RDA guidelines should be followed for general supplementation purposes, but much higher doses are often recommended for the treatment of specific conditions (such as a vitamin B6 deficiency). In this case, you should follow your healthcare provider's dosing recommendations.

An Introduction to Pyridoxine Dosage

The recommended dose of pyridoxine (vitamin B6) depends on several different factors, such as:
 
  • Your age
  • The reason you take pyridoxine
  • Other medical conditions you may have.
     
As always, do not adjust your dosage without your healthcare provider's approval.
 

General Supplementation

For general supplementation purposes, the Recommended Dietary Allowances (RDAs) of pyridoxine are as follows:
 
Age
RDA
0 to 6 months*
0.1 mg daily
7 to 12 months*
0.3 mg daily
1 to 3 years
0.5 mg daily
4 to 8 years
0.6 mg daily
9 to 13 years

51 years and older (men)
1.7 mg daily
51 years and older (women)
1.5 mg daily
Pregnant women
1.9 mg daily
Breastfeeding women

*RDAs are not established for pyridoxine for infants under one year old; instead, an "Adequate Intake" level is provided.
 
For nutrients that can cause toxicity, a "Tolerable Upper Intake Level" (UL) is given. This is the maximum that can be taken (from all sources, including the diet) without causing significant toxicity. Refer to the following table for UL values for pyridoxine:
 
Age
UL
0 to 12 months
(not established)
1 to 3 years
30 mg daily
4 to 8 years
40 mg daily
9 to 13 years
60 mg daily
14 to 18 years
80 mg daily
19 years and older
100 mg daily
