Extensive scientific data and experience with thousands of users has proved that daily feeding of 15 mg of pure Biotin results in the formation of healthy keratin in most horses.
This daily application is essential, preferably over several months, because a lower application, which may be nutritionally beneficial, does not have the effect of hoof strengthening.
Supplements marketed as containing Biotin should be checked to ascertain the potency, which may not be sufficient for hoof health.
