What the AI looks for in Vitamin B-Complex Supplements
- B6 content
- Prefer products with 25 mg of B6 or less per serving for daily use, and lower is better. Many 'B-50' and 'B-100' formulas carry enough B6 to risk neuropathy over the years.
- Niacin form
- Niacinamide avoids flushing. Nicotinic acid in a complex can cause flushing. Flushing is the most common reason people stop taking a complex.
- B12 and folate forms
- Methylcobalamin or cyanocobalamin with methylfolate or folic acid are all effective. Check that the folate is not above about 1,000 mcg DFE without a reason. The form matters less than an adequate and safe dose.
- Biotin load
- Note the biotin amount. Complexes with hundreds of mcg or more can interfere with immunoassays. Biotin distorts thyroid and troponin test results.
Brands that matter
- Pure Encapsulations: Clean, hypoallergenic complexes.
- Thorne: Basic B Complex is the active-form benchmark.
- Nature Made: Low-cost, mainstream option.
- Garden of Life: Whole-food-style complexes for those who prefer that approach.
What to avoid
- 'B-100' complexes taken long term without need.
- Taking a complex together with a multivitamin and an energy drink without adding up the B6 totals.
