Platinum Skin & Allergy is a potent allergy formula that may be helpful in horses with skin or respiratory allergies. This formula works by helping to maintain a healthy immune system and providing ingredients like Quercetin, a naturally occurring antioxidant, to maintain healthy histamine levels. Best results will be seen when used in conjunction with Platinum Performance® Equine because of the beneficial effects of the Omega-3 Fatty Acids found in that formula.
