About half the European population is deficient in magnesium. Modern agricultural practices deplete soil of magnesium, leading to less magnesium in the foods you eat. Many common medications also deplete magnesium levels. Multivitamins often contain less than 1/4 of the RDA and absorption varies greatly based on the form of magnesium in the supplement. If you aren’t critically low on magnesium, you only absorb about 30–50% of dietary magnesium (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4455826/). Your colon eliminates the rest, which is why magnesium is often used in laxatives.
