Science Supplements ProKalm is an innovative supplement designed to aid concentration and help horses perform at their best. Scientifically engineered and tested, this supplement has been proven to aid concentration in demanding situations. ProKalm helps manage stress and anxiety in horses, addressing behaviors like bolting, pulling, spooking, wind sucking, crib biting, box walking, stamping, and poor concentration, which can lead to increased susceptibility to infections, gastric ulceration, loss of condition, and poor recovery from exercise and competition. It is best given regularly in feed, with effects beginning within 30 minutes and lasting up to 8 hours. The dosage can be adjusted based on individual horse needs.
