Description
Cod Liver Oil is a good, natural source of vitamins A and D. Vitamin A plays a major role in our visual system, where it is necessary for the normal functioning of our eyes and vision. Vitamin A also affects growth and development of our lungs, teeth, gums and skin, and is essential for proper immune function. Vitamin D is necessary for bone development and plays a principal role in the proper absorption of calcium. The main sources of Vitamin D are food and sunlight. Since we are able to produce Vitamin D in our skin from sunlight, it has hormonal action in the body as well as vitamin activity. Those who do not get any sunlight (particularly the elderly in nursing homes) may be at a higher risk of Vitamin D deficiency and supplementation is recommended. However, because Vitamin D is a fat-soluble vitamin, it is important to take it according to recommended amounts.
