It’s difficult to give you a proper answer without knowing your horse, his morphology, his age, his eating habits, etc. As for us, we don’t have oils. However, we have a large range of food supplements made to maximize the physical condition :
NUTRILIFE+ : It is a food supplement high in vitamins which contains all the elements to complete your horse’s daily ration, whatever is his activity. It looks like granules to mix with the ration, 90g per day during a month. It contains 20 essential ingredients (vitamins, minerals, calcium, phosphorus, etc.)
NUTRIGARLIC + : It’s a food supplement to mix with your horse’s ration too. It contains essential elements including garlic, flax and cod-liver oil, beetroot, barley, etc. You give 30g per day during a month to renew 3 times a year.
During intense show season, I advise you to use NUTRIFORME too : it prepares your horse to a sustained effort. It contains trace elements and magnesium. It is liquid and has to be mixed to the ration, 30 ml per day during a month.
