Vitamin-Mineral Supplements

When we think about feeding horses, we tend to concentrate mostly on the macronutrients. Most of the focus is on whether the horse has enough hay, pasture and grain. However, it is also important to incorporate micronutrients into your equine’s diet, as they play an important role in the well-being of a horse.

Macro- and Micro-Minerals

Due to the volume required in the average horse’s diet, minerals are generally divided into two categories: micro and macro.

Macro-minerals include phosphorus, magnesium, calcium, potassium, chlorine, sodium and sulfur. These minerals are required in large volumes because they are critical in the development and sustenance of acid-base balance, the skeleton, hoof and hair growth and nervous system activity.

Unlike macros, micro-minerals are typically needed in smaller quantities. These minerals include iodine, copper, iron, selenium, manganese and zinc. Micro-minerals play a key role in helping to metabolize nutrients, transport oxygen to muscles, maintain connective and joint tissues and perform as antioxidants.

Fat-Soluble and Water-Soluble Vitamins

Horses also need vitamins to stay healthy and achieve peak performance. Vitamins are broken into two categories: fat-soluble and water-soluble.

Fat-soluble vitamins include vitamins A, D and E. Just as their name suggests, these vitamins are stored in the body’s fat deposits. It is important to monitor the intake of these minerals, as too much can be toxic to the horse. The main functions of these vitamins are to ensure proper vision, regulate the absorption of calcium and act as a primary antioxidant, which protects the horse’s muscles.

Water-soluble vitamins commonly referred to as B vitamins, include thiamin, riboflavin, niacin, biotin and folic acid. It is easy to neglect these vitamins. While they do nourish the tissues, water-soluble vitamins are not stored in the body but are eliminated in urine. However, it is important to note they are critical in nearly all the body’s chemical processes. As such, they are essential for growth, metabolism and generating energy.

Some horses need water-soluble vitamins more than others and may require an equine vitamin and mineral supplement like B-500 to ensure they get enough nutrition.

These include horses that:

  • Compete or train vigorously
  • Live in high-stress environments
  • Don’t have proper access to fresh green grass or are consuming poor-quality hay
  • Are young and growing
