Vitamin B6 Dosage

Vitamin B6 Dosing for Specific Uses

For treating specific conditions (such as a vitamin B6 deficiency), much higher doses are often recommended. If you have a documented vitamin B6 deficiency, follow your healthcare provider's recommendations for your dosage (and the type of vitamin B6 to use). Recommended dosages can vary widely, depending on numerous factors.
If you are using vitamin B6 to self-treat any condition (such as premenstrual syndrome or infertility), make sure not to exceed the Tolerable Upper Intake Level for your age group. Also, be sure to watch for any signs of vitamin B6 toxicity, especially if you take doses higher than the RDA.

General Information on Taking Your Dose of Vitamin B6

Some considerations for people taking vitamin B6 include:
  • Non-prescription vitamin B6 products are classified as dietary supplements, not drugs. Therefore, they are subject to less rigorous manufacturing standards, compared to drugs. When choosing any supplement, it is important to choose a high-quality product from a trustworthy manufacturer. Your pharmacist is a good resource for information about which manufacturers are most reputable.
  • Never exceed the amount recommended on the supplement label unless your healthcare provider specifically recommends that you do so.
  • If you are unsure about anything related to your dosage or vitamin B6 dosing in general, please talk with your healthcare provider.
