Overview

Puritan's Pride Mega B-100 provides a robust blend of B vitamins at high dosages, alongside choline, inositol, and PABA. Most B vitamins are delivered at levels significantly exceeding daily recommendations, which can be effective for correcting deficiencies or supporting higher metabolic demands. However, the use of folic acid instead of more bioavailable folate forms, and the inclusion of a proprietary blend for the botanical components, reduce overall transparency and the ability to fully assess the efficacy of these specific additions.

The Good

Comprehensive B-vitamin profile for overall health and energy metabolism.

B vitamins provided at dosages generally recognized as effective for deficiency correction or therapeutic support.

Includes Choline and Inositol, which support brain health and metabolic processes.

The Bad

Folic acid (400mcg) is included rather than the more bioavailable methylfolate, and it can mask a vitamin B12 deficiency.

Significantly high doses of many B vitamins (e.g., 100mg Thiamine, Riboflavin, Niacin, B6, Pantothenic Acid) far exceed daily requirements, potentially leading to unnecessary exposure or specific side effects like niacin flush or B6 neuropathy over time.

The 'Proprietary Blend' of herbal powders (Parsley Leaves, Rice Bran Defatted, Watercress Leaves, Alfalfa Leaves, Soy Lecithin Granules) is dosed at a mere 5mg total, making it highly unlikely for any of these ingredients to be present at an effective dose.
