Vitamin B12 supplements are available in various forms, including cyanocobalamin, methylcobalamin, and adenosylcobalamin. Cyanocobalamin is the most common and cost-effective form, while methylcobalamin is often preferred for its bioavailability. It is essential to consider factors like absorption rates, dietary restrictions, and personal health needs when choosing a supplement. Consulting a healthcare provider can help determine the most suitable form and dosage.
