what does a magnesium supplement do for you
Studies have shown that when magnesium intake is low, calcium supplementation may reduce magnesium absorption and retention. And, whereas calcium supplementation can have negative effects on magnesium levels, magnesium supplementation actually improves the bodyâs use of calcium.. Most dark colored sodas contain phosphates. These substances actually bind with magnesium inside the digestive tract, rendering it unavailable to the body. So even if you are eating a balanced diet, by drinking soda with your meals you are flushing magnesium out of your system.
