(JERUSALEM POST) — Vitamin D supplementation has been found by researchers in Israel and Russia to improve immune function in COVID-19 patients – and is thus recommended for them, as well as for healthy people.
Your body uses Vitamin D to absorb minerals like calcium and phosphorus. Not only does it strengthen your teeth and bones, it also benefits the muscles, nerves and immune system.
Although you can get it from sunshine on your skin, this ability declines with age. It can be hard for anyone to get enough vitamin D each day through sun exposure and food alone, so taking supplements helps.
