Research shows that nearly 75% of the US population is deficient in Vitamin D. Simple supplementation with Vitamin D can help restore a good mood, protect the bones, and increase immunity. Not all Vitamin D supplements are created equally. The form that is most absorbable and utilizable by the body is cholecalciferol, or Vitamin D3.
Vitamin D is a fat soluble vitamin which means that it dissolves in fat tissue, or lipids, when it is ingested. It is also synthesized in the body when the skin is exposed to ultraviolet rays from sunlight. I recommend exposing the arms and legs to natural sunlight two times a day for about 15 minutes in the morning or early evening.
Cataplex D contains 800 iu of Vitamin D, the recommeded amount, plus 1000 iu of Vitamin A to support the proper absorption of the D3.
