Linseed Oil Alex often recommends this cold pressed pure linseed oil for horses as it is naturally high in Omega 3 and works alongside weight and strength bespoke supplements. The use of linseed oil in a daily feed is a traditional and proven way of giving oil to equines rather than using a dried version. Omega 3 is known to reduce the build up of lactic acid in muscles, which is a common cause of fatigue in competition horses. It helps to improve coat texture for a fuller and shinier appearance and can be fed in higher doses to improve condition too.
