The "sunshine vitamin" and pro-hormone so vital to the body's wellness. In 20 minutes of a good, summer day in the sun, the skin can absorb 10,000 to 50,000 IU's of D3, providing the body with the ample amount it needs to remain "well oiled".
Vitamin D is an immense contributor to immune system function. It also plays a key role in regulating calcium in the body -- promoting absorption which helps bone mineralization to occur. Adequate Calcium and Vitamin D intake throughout life, along with a healthy diet, are essential to reduce osteoporosis risk, but there are also other factors.
When the body is getting enough D to go around, it is used liberally by many cells that are able to make calcitriol. Some of the most exciting research today is finding that D3 deficiency is a common factor in many ailments. It is not apparent in all cases whether the low levels caused the ailments or were caused by the ailments, but in either case, D3 supplementation seems like a good idea.
Vitamin A is a fat-soluble vitamin that also works as an anti-oxidant in the body. It is found only in animal fats and some of the richest sources for this nutrient are butter, liver, egg yolks, and cod liver oil.
Vitamin A is the name of a group of fat-soluble retinoids, including retinol, retinal, and retinyl esters. Vitamin A is involved in immune function, vision, reproduction, and cellular communication. Vitamin A is critical for vision as an essential component of rhodopsin, a protein that absorbs light in the retinal receptors, and because it supports the normal differentiation and functioning of the conjunctival membranes and cornea.1
Having a good source of vitamin A is of special importance to diabetics as they aren’t always able to properly convert beta-carotene (the precursor to vitamin A found in many plant foods) into vitamin A and can often become deficient. The thyroid also uses a great deal of vitamin A and those with sluggishly functioning thyroids are also in great need of vitamin A that doesn't need to go through a conversion process. Lastly, various stresses on the body use up a great deal of vitamin A and replenishing in such times is key!
Synergistic Checks and Balances
Some of the processes in the body that rely on Vitamin A coincide with those that need Vitamin D, such as bone formation and healthy immune function. Vitamin A and Vitamin D also need each other in order to function fully as vitamins, so getting them into the body together and in balance is vital. These two fat-soluble vitamins work synergistically in one other way, helping to check vitamin A toxicity.
Vitamin A, taken with vitamin D, controls the risk of vitamin A toxicity as the two compete for receptors. Taking the two vitamins together in the proper balance is the safest way to deliver vitamin A to the body. The provision that we find for this is largely seen in nature. Foods that are rich in vitamin A also often have a good supply of vitamin D, as well! A very good ratio of vitamin A to vitamin D is 10 to 1 or less.
