They might not be magical cure-alls, but with benefits such as reducing inflammation and skin reactivity to allergens, omega-3 fatty acids could be considered go-to supplements for horse owners wishing to improve their horses’ health and performance.

Omega-3 fatty acids are long-chain polyunsaturated fatty acids (PUFAs), which help provide structure to cell membranes in tissues across the body. Once incorporated into cell membranes, omega-3 and -6 fatty acids can elicit a slew of metabolic effects in tissues, such as helping regulate cell signaling. Omega-3s can also be cleaved from the cell membrane to produce eicosanoids, a type of immune system messenger used to inhibit inflammation.

With horses, specifically, added PUFAs have many benefits, such as improving exercise parameters, lowering heart rate, increasing sperm production in breeding stallions, improving immune response, and potentially improving insulin sensitivity, or the body’s responsiveness to the hormone insulin signaling the removal of glucose from the blood after a
