For our readers today we have gathered 3 incredibly common vitamin deficiencies and ways to tackle them.

Vitamin D 

The most common vitamin deficiency is Vitamin D deficiency. Vitamin D itself is a fat-soluble vitamin which acts as a steroid hormone for the human body. This vitamin travels via the bloodstream to every cell of the body and tells them either turn on or turn off the genes in them. Each cell of the body has a receptor for the vitamin D.
