Best multivitamin? Worried about high B6 so maybe one without that? Or.. how do I avoid high B6?
Understanding the Risks and Managing Vitamin B6 Intake
Recommended Dietary Allowances (RDA) and Upper Limits (UL)
- The RDA for adults varies based on age and gender, but generally lies around 1.3 mg per day for men aged 14-50 and women aged 19-501.
- The Tolerable Upper Intake Level (UL) for vitamin B6 for adults is 100 mg per day, significantly higher than the RDA1. This level is designed to avoid adverse side effects like neuropathy (nerve damage) and ataxia (loss of control of bodily movements).
Avoiding Excessive Vitamin B6
- Supplements: Most cases of vitamin B6 toxicity occur from taking high-dose supplements. Therefore, choosing multivitamins with lower B6 content or avoiding additional B6 supplements altogether is recommended2.
- Diet: It's very unusual to reach toxic levels of B6 through diet alone, as the vitamin is water-soluble and excess amounts are usually excreted through urine2.
- Symptoms of Toxicity: Some signs of excessive B6 include neuropathy in the hands and feet, ataxia, and nausea, even though these symptoms typically resolve after discontinuing high dosage3.
If you're looking for a multivitamin without vitamin B6, or one with low B6 content, I can help you find suitable products. Would you like me to search for some options?
