Docosahexaenoic acid (DHA) - Feed Ingredient

Docosahexaenoic acid (DHA) is a long-chain omega-3 fatty acid primarily found in marine sources such as algae and fish oil. It is one of the most biologically active forms of omega-3s, along with eicosapentaenoic acid (EPA). DHA is characterized by its 22-carbon chain and six double bonds, which contribute to its fluidity and functionality within cell membranes.

In equine nutrition, DHA is often included in feed or supplements aimed at supporting inflammatory balance, cognitive function, and reproductive health. It is commonly derived from algal oil for use in equine products, offering a vegetarian alternative to fish oil. Compared to plant-based omega-3s like alpha-linolenic acid (ALA), which is found in flaxseed or chia, DHA is more readily utilized in the body without requiring conversion. Horses have limited enzymatic capacity to convert ALA into EPA and DHA, making preformed DHA a more efficient and potent source for supporting anti-inflammatory pathways.

The following equine feeds, supplements and products contain Docosahexaenoic acid (DHA) as an ingredient.
