Vitamin E, a fat-soluble antioxidant, exists in eight different forms; alpha-tocopherol is the most biologically active. In canine nutrition, providing adequate amounts of this vitamin is crucial for maintaining optimal health. This nutrient plays a vital role in protecting cell membranes from oxidative damage caused by free radicals.
The significance of this vitamin extends to supporting immune function, cardiovascular health, and neurological well-being in canines. Historically, deficiency has been linked to muscle weakness, reproductive problems, and vision impairment in dogs. Supplementation is sometimes necessary, especially in diets high in polyunsaturated fatty acids, as these increase the demand for antioxidant protection.
