Five of the most important B vitamins for horses, combined with inulin and yeast to promote their own B vitamin production in the gut. Good for example when the horse is exposed to feed changes, stressful environments or has a diet with little fibre (or large concentrated feeds) when it may need to be supplemented with B vitamins as the horse cannot produce enough itself. Can also be good for moulting or when the horse is shedding, as it is especially important that it has enough of the most important B vitamins. 450g
