Buying Guide

Check active B-vitamin forms

Look for methylated folate (folate/folinic) and methylcobalamin B12 when you need forms the body can use more directly for nerve health

Assess total B-vitamin potency

Higher mg amounts (like 100 mg formulas) can suit deficiency correction or high demand, while lower potencies may be better for daily maintenance—match potency to your needs

Consider added supportive nutrients

Formulas that include vitamin C or biotin add immune and cellular support, which can be beneficial but may affect price and serving size

Verify capsule vs tablet and serving size

Capsules and tablets can differ in absorption and number per serving—check total capsules/tablets per bottle to compare cost per dose

Look for quality and transparency

Choose brands that disclose full B-vitamin dosages, use recognizable ingredient forms, and provide clear labeling of tablet count to calculate value
