What do the nutritionists mean when they talk about 1:1 or 2:1 minerals?
Usually minerals are described as 1:1, 2:1, or 3:1. The numbers are the ratio of calcium to phosphorus in the product. The absolute amount of calcium and phosphorus can differ among products. For example a 2:1 mineral could be 14% calcium and 7% phosphorus or 20% calcium and 10% phosphorus. However, if you need to add a lot of calcium you should choose a mineral product with a higher calcium number e.g. the 20% product. Your horse specialist or nutritionist can tell you which product to use.
