This supplement is the real sunshine in a bottle. The purpose of this supplement is to provide the horses with extra vitamin D in the winter months. Vitamin D is dissolved here in a mixture of flaxseed oil and wheat germ oil that relate to the ideal omega 3 – 6 – 9 ratio. As is well known, vitamin D is important for strong bones.
