Most calcium and magnesium supplements contain a ratio of two parts calcium to one part magnesium. The logic behind this ratio is based on the relative amounts of these nutrients used in the body. But in order to determine how much we might need to take as a supplement, we should consider how much of these nutrients we are getting in our food and how they are stored and recycled in the body.
