Nutricology Children's Multi-Vi-Min was formulated by Stephen A. Levine, Ph.D. to be hypoallergenic, and many people who cannot tolerate a complex nutrient formula do well with the Multi-Vi-Min formulas. Children's Multi-Vi-Min uses a small capsule size ("3") for easy swallowing, suitable for children and for adults who have problems swallowing capsules. The formula utilizes the purest USP grade materials, which are ultimately synthesized from naturally occurring sources. Vitamins B2 and B6 are supplied partially in their coenzyme ("activated") forms. Vitamin C was purposely left out because of its ability to enhance iron absorption. These nutrients are of the highest quality and purity obtainable, free of all common allergens (antigens), and do not contain preservatives, diluents, or artificial additives.
