The Pros and Cons of Feeding Hemp to Horses

Hemp has become a talking point in equine nutrition over the last few years, and it is easy to see why. Horse owners are always looking for ways to support coat quality, condition, gut health, topline and overall wellbeing without overloading the diet with starch and sugar. Hemp products — including hemp hulls, hearts and hemp seed oil — are now being used in many feeding programs for exactly that reason. Hemp ingredients are naturally rich in fibre, beneficial fats and useful plant nutrients, which makes them appealing for a wide range of horses. 

That said, hemp is not a miracle feed, and it is not the right fit for every horse in every situation. Like any feed ingredient, it works best when you understand both the benefits and the limitations. If you are considering hemp products, it helps to look at hemp for what it really is: a useful nutritional addition that may suit some horses very well, but still needs to be fed appropriately as part of a balanced ration. 

One of the biggest advantages of hemp is its nutrient profile. Hemp-based horse feeds can provide a combination of fibre, fat and protein in one ingredient. Hemp is high in fibre, naturally rich in omega 3, 6 and 9 fatty acids, and a source of protein, while remaining very low in sugar and starch, which makes it attractive for owners wanting a low-NSC addition to their horse's diet. 

That low sugar and starch content is a major reason some owners are interested in hemp. For horses that need calories without the fizz often associated with high-grain feeds, fat can be a useful energy source. Hemp seed oil is marketed as a “cool energy source,” and more broadly, equine nutrition guidance recognises oils and fats as a practical way to add calorie density without relying on carbohydrate-heavy feeds. This can make hemp oil or hemp hulls and hearts worth considering for horses in work, poor doers, or horses that need extra condition but do not cope well on cereal-based energy sources. 

Another commonly discussed benefit is coat and skin support. Products rich in essential fatty acids are often used by horse owners to help maintain skin condition and coat shine, especially in horses that look dull, dry or scurfy. Hemp oil is notable because it contains polyunsaturated fats, and some equine nutrition sources note its content of fatty acids such as stearidonic acid and gamma-linolenic acid. While results will vary between horses, this type of fat supplementation is one reason hemp products are often chosen during coat changes, dry seasons or times of extra nutritional demand. 

Fibre is another point in hemp’s favour. Horses are designed to thrive on fibre, and any ingredient that supports fibre intake can be useful when it fits the rest of the ration. A hemp hulls-and-hearts product can add bulk and roughage-like value while also bringing extra fat and protein to the bucket. For some horses, that makes hemp an easy way to add nutrition without feeding a large volume of grain or concentrates. This may be particularly appealing for owners wanting to support condition in a way that feels more “slow release” and forage friendly. 

However, there are also downsides and cautions to keep in mind. The first is cost. Hemp products can be more expensive than some traditional feed ingredients, especially if they are being fed daily over the long term. For some horses, the benefits may justify the cost. For others, similar nutritional goals might also be met with more conventional options such as linseed, canola oil, soybean meal or a well-formulated complete feed. Hemp can be a great addition, but it should still earn its place in the feed room.

The second consideration is balance. Hemp contains useful nutrients, but it is not a complete ration on its own. Feeding hemp does not remove the need to balance minerals, vitamins, forage intake and total energy needs. A horse can still be deficient or unbalanced overall if hemp is added to an otherwise poor diet. This is important because owners sometimes assume that adding one “superfood” ingredient will fix multiple issues. In reality, hemp is best viewed as one part of the bigger nutritional picture, not the whole answer. 

There is also the issue of expectations. Hemp is often talked about in ways that blur the line between nutrition and medicine, especially when people start discussing calming effects, inflammation or behaviour. The strongest nutritional case for hemp in horses is around its fibre, fat, protein and fatty acid content. Claims beyond that can get ahead of the evidence quite quickly. In particular, CBD and cannabinoid-related discussions are separate from plain hemp seed nutrition, and the research base in horses is still developing. That means owners should be cautious about dramatic promises and stick with sensible feeding goals.

Competition horses need extra care here. The FEI warns generally about supplement contamination risks, and cannabinoid-related substances can create significant issues in regulated sport. Hemp seed products generally contain negligible cannabinoids, however trace amounts can still remain. Hence, owners of competition horses should always check the latest rules, keep records, and speak with the manufacturer if they have questions around testing and suitability. 

Another practical con is that fats should always be introduced gradually. Horses do not do well when significant dietary changes are made overnight, and added oils in particular should be brought in slowly. It is recommended to introduce any hemp seed products  gradually over about two weeks. 

So, which horses might suit hemp? In general, hemp may be worth considering for horses needing extra cool calories, horses needing support for coat and skin condition, horses that do better on low-starch diets, or owners wanting to add a fibre-and-fat ingredient to the feed bucket. Products such as Provex Hemp Seed Oilmay suit owners wanting a more concentrated fat source in a smaller daily serve. 

On the other hand, hemp may be less suitable where budgets are tight, where a horse already has a well-balanced ration that is working well, or where the owner is hoping for unrealistic changes in behaviour, soundness or performance from a feed ingredient alone. Hemp can support a feeding program, but it is not a shortcut past good hay, correct workload, dental care, worming strategy and an overall balanced diet.

In the end, hemp has genuine positives for horses. It can provide fibre, beneficial fats, low-starch calories and useful protein in a form many owners find easy to feed. Products like Provex Hemp make that option more accessible for horse owners wanting to explore hemp as part of a modern feeding program. But the best results come from using hemp thoughtfully — not as a fad, and not as a cure-all, but as one practical tool in a well-managed ration.
