B-Vitamin Supplements for Horses

View a list of the best B-vitamin supplements for horses in Mad Barn’s equine feed database. B-vitamins are water-soluble nutrients involved in energy metabolism, nervous system function, red blood cell production, hoof and coat quality, and normal digestive function.

Equine B-vitamin supplements may provide individual nutrients such as thiamine, riboflavin, niacin, pyridoxine, folic acid, biotin, cobalamin, and pantothenic acid, or a full B-complex formula. These products can vary widely in vitamin concentrations, serving size, format, and added ingredients such as yeast, amino acids, minerals, herbs, or digestive support compounds. Compare B-vitamin levels, ingredient sources, feeding directions, cost per serving, and nutritional profiles to find a supplement that fits your horse’s needs.
