DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
The Recommended Daily Allowance (RDA) of magnesium for young adults is around 400 mg/day for men and 310 mg/day for women. For adults over 30, the RDA is 420 mg/day for men and 320 mg/day for women. However, despite how easy it is to find magnesium, studies have shown that between 68% and 75% of American adults are magnesium deficient.
