10 Best Horse Supplements in 2023 – Reviews & Top Picks
Horses can get most of the nutrition that they need from foraging grasses and weeds that grow in the fields that they live on. But supplements might be necessary if foraging is scarce or a horse is ill. Young horses that are growing quickly and older horses that are coming to the end of their life may also benefit from supplemented food at mealtime, especially if they are being fed hay bales and other foods rather than foraging. Luckily, there is no shortage of horse supplements available on the market.
The problem is that with so many options available, it can be tough to determine which would best serve a horse that requires extra nutrition. So, we set out to make the process of choosing horse supplements easy for you. We combed the market for the best supplements out there and created a list of 11 that deserve consideration, and we also put together reviews for each option on the list. Hopefully, you will find exactly what your horse needs! Read on to learn about our top 11 favorite horse supplements.

Buyer’s Guide: Selecting the Best Horse Supplements
Buying horse supplements should be about more than just deciding which are most affordable and which claim to do what you need them to. There are several things that you can do to make the supplement-buying process more convenient and ensure great results as time goes on. Here are a few tips and tricks to consider.
How to Know What Your Horse’s Exact Needs Are
Before you consider which supplements to offer your horse, it is important to understand what kinds of supplementation they need. Just because they do not seem to be acting or looking themselves does not mean that just any supplement will take care of their problems. It is extremely important to have a veterinarian visit your horse for a checkup and tests that will help you determine what kinds of supplements you should be offering your horse.
Your vet can help you decide which ingredients to look for and which to avoid, which is especially important if your pet is susceptible to allergens of any kind. You should keep an eye on how your horse is acting and document any changes in coat health, lung health, joint or bone pain, and overall health so your vet can more easily help you identify the types of supplements to look into.
Deciding How Often to Offer Supplements
Once you decide which types of supplements to offer your horse, you need to figure out how often those supplements should be fed to them. For instance, if your horse needs a supplement that offers vitamin C to increase their immune system, should they be fed a vitamin C tablet once a day or once a week? It all depends on their current vitamin C levels which brings us back to the veterinarian.
Blood tests can be done to determine exactly what amounts of nutrients are being absorbed and digested into your horse’s body for active use. These tests will help you determine whether your horse is deficient in any specific nutrient, and if so, the severity of the deficit can be estimated. You can then choose supplements that meet those deficiency needs and experience a happier and healthier horse when all is said and done.
Figuring Out If Combining Supplements Is Right for Your Horse
Your horse may be deficient in multiple nutrients, or they might have a nutrient deficiency along with a joint issue. Regardless, it can be confusing as to whether you should combine supplements to meet all your horse’s needs. If you are offering your horse truly natural supplements that are designed to target specific needs, you can combine supplements to create a custom treatment protocol that meets their current and long-term needs.
If you are ever in doubt, contact your veterinarian so you can work together to create the custom protocol that your horse needs. You may need to experiment a bit, but with the help of a vet, you should be able to avoid the stuff that would cost you money without improving the health of your horse overall. If anything, you can get expert advice about the specific nutrients that your horse needs, then you can decide how best to provide those nutrients through supplements at home.

Storing Your New Horse Supplements
Another thing to think about when buying horse supplements is how you will store them. What kind of packaging does the supplement product come in? How well does the package seal out air? These are important questions because if a supplement gets exposed to air unnecessarily, it can become rancid and un-useful prematurely. So, check out user reviews, and contact the selling company to find out how their package performs.
If necessary, you can purchase a 5-gallon bucket with a lid or another similar container to store your horse supplements in that will help protect them from the elements. Supplements that do come in protective containers should not be left outside, even if they claim to be weather resistant. Moisture and humidity can change the integrity of a supplement product and make it less effective as time goes on.
You may need to store a supplement in the fridge or in a dark space within your home. Some supplements may do well in sunlight and can be kept next to the food bowls. Take the time to find out the best storing practices before buying a certain horse supplement to ensure that you can meet its demands.
