Magnesium intakes are low in the typical Western diet and current recommendations are to increase intake. Choosing a form of magnesium that is well absorbed and affordable is therefore of interest to those who wish to preserve or improve their health. Studies show that magnesium intakes in the form of magnesium acetate cause incremental increases in absorption, although the percentage of absorbed magnesium falls with each intake from around 65 % to 11 %. Further, the magnesium from a magnesium rich food such as almonds is also high compared to the absorption from magnesium acetate. In addition, at the same relative concentration, calcium intake is greater compared to magnesium intake. These results support other studies in suggesting that dietary magnesium is well absorbed and increasing the concentration of magnesium in the diet increases absorption at the expense of the efficiency of the absorption process. Eating foods for magnesium is also beneficial if a suitable food can be sourced.
