It is recommened to store oils like this one in cool conditions, for no longer than three months. If left in a hot area or left exposed to the sun rays, linseed oil may become rancid and poisonous to the horse, and thus should be stores in the fridge during summer months. Oil supplements should not be given constantly throughout the whole year, but rather intensively for short periods of time (eg. 3 months).

Natural Ingredients
Gold Label Brewers Yeast

Yeast has many beneficial effects on horses health and condition.

Available at Amazon

Gold Label Brewers Yeast skin & coat conditioner for horses is a pure yeast in a form of a fine powder. It should be added to your horses daily feed according to the instructions. Yeast are known for their high levels of B vitamins, including thioamine, nicotinic acid and riboflavin. These vitamins promote a healthy coat, stronger hooves and overall healthier appearance. Yeast is often recommended by veterinarians for horses that tend to rub and bruise easily, or horses that have a dry and flaky skin. Apart from the previously mentioned properties of B vitamins, yeast act as a natural prebiotic in your horses gut (as a fuel for the healthy gut bacteria) and improve the health of the nervous system. Therefore yeast can be given to anxious and hot horses to help them remain calmer. Horses with digestive problems such as ulcers or reoccurring diarrhoea or constipation will also benefit from a yeast supplement. Yeast is also an amazing supplement for horses that are fussy and picky when it comes to eating, since yeast is believed to increase the appetite.

What to Look for in Horse Coat Supplements

Here are some of the things to look for in the ingredient lists, when buying horse coat supplements


Vitamins, especially vitamins B improve the skin and coat quality. Vitamins B can be found under the names: biotin, yeast, thioamine, nicotinic acid or riboflavin. Although B vitamins are the most popular group of vitamins associated with the coat, other vitamins are also responsible for the coat quality. Fat soluble vitamins, such as A, D, E and K are famous for they anti oxidative properties and improve the coat heath too.


Omega 3 and 6 fatty acids are found in oils. Most popular oils that can be safely supplemented to horses include: linseed oil (or flax seed oil), soybean oil, corn oil, rice oil and fish oil (salmon, cod, etc.). Linseed oil is the cheapest and most accessible. The use soybean oil is controversial as most soya beans are genetically modified. Fish products are generally most expensive. Rice oil provides horses with a lot of extra energy and is therefor often used in sport horses nutrition. The side effect of using rice oil is the increase of blood testosterone, so the supplementation should be avoided during the competition season (you might be disqualified for dope, according to the FEI rules)


Probiotics do not have a direct effect on the horse’s coat but rather on the gut. They improve the gut health, aid digestion, help with regular and healthy bowel movements, prevent diarrhoea or constipation and help heal the ulcers. You might wonder then, why are probiotics on this list? Well, a healthy gut can absorb more vitamins and minerals resulting in a healthier skin and coat, and improved horse’s general well-being.
