Our Horses Love these Salt Licks! A 550 million year old source of minerals and trace elements. Mined from the vast and ancient Himalayan mountains, these salt licks are the purest form of salt available. The distinctive rose pink color comes from the salts high mineral content, such as iron, potassium and magnesium, which are all vital for maintaining health. Himalayan rock salt licks are literally "rock hard", this means it is difficult for horses and ponies to bite chunks off the block, a problem that can occur with the softer pressed salt licks. These licks are also much more weather resistant and will last 5 to 6 times longer.
