People can suffer from Vitamin D deficiency. The most commonly identified causes are dietary or lack of exposure to sunlight. The typical solution is to supplement through Vitamin D capsules. As medication and food supplements have been traditionally in the form of pills and tablets, people will naturally assume they’re getting their money’s worth and take the effectiveness as a given.
Operation of Vitamin D
Vitamin D has a whole range of essential benefits depending on how it is processed. The whole thing starts in the skin where a kind of inherent cholesterol known as 7-dehydrocholesterol reacts from the sun’s ultraviolet radiation to form cholecalciferol also known as Vitamin D3. This substance is taken to the liver where it is then converted into 25-hydroxy vitamin D. This new substance is in turn either processed in the kidneys or by the immune system. As part of the immune system, its role is to defend against foreign microbes. As a hormone synthesized in the kidneys, it controls the amount of phosphate and calcium in the blood and so ensures proper bone health and development. Other functions include regulation of nerve and muscle function and even decrease of inflammation. It is one of the nutrients that help you recover from physical stress. The nutrient in Vitamin D capsules is already in the form of cholecalciferol since it is taken orally and doesn’t go through the photo-reaction stage.
Variable required amounts of Vitamin D
Vitamin D capsules come in various standard dosages set by agencies like the Food and Drug Administration and other national health institutions. Although there are recommended dosages, current studies still don’t clearly agree on what the nominal amount is for a healthy person. In fact there has been some research that showed even people who enjoy regular sunlight can be Vitamin D deficient. Unlike other essential nutrients, determining the correct level of Vitamin D is more a matter of individual diagnosis. The most accurate method so far is to measure the amount of 25-hydroxy vitamin D in the bloodstream. It is recommended that one consults a doctor and undergo this type of blood test to get a precise picture. Over dosage of Vitamin D can be just as harmful as deficiency.
Limitations of Vitamin D capsules
Cholecalciferol is structurally similar to most types of cholesterol. This is the reason why Vitamin D is sometimes called an oil-based nutrient. Consequently the capsule, gel cap, even liquid forms of Vitamin D food supplements will have oil as an ingredient. There are certain disadvantages that come with these characteristics. Vitamin D capsules first need to go through and be broken down by the digestive tract before it can proceed to the liver and be metabolized to 25-hydroxy vitamin D. This does not necessarily result in the complete absorption of the full dosage. The medium or ingredient used is also questionable. Some brands may utilize oil from genetically modified soy. The full effects of ingesting products made from genetically modified organisms have not yet been fully researched. One who is truly conscientious about his or her health should be wary of such products.
An alternative solution
Since the stumbling block for Vitamin D capsules lies in the effectiveness of absorption, the solution was to reduce the particle size. Instead of pills that still needed to be swallowed and broken down, the vitamin is housed in a special container that sprays into the mouth. The mechanism can be calibrated and deliver an exact dosage. The fine mist that comes out is made up of molecule-sized particles of the vitamin. Thus the nutrient is directly absorbed through the mouth tissues and quickly enters the blood stream, bypassing the digestive system altogether.
Because of this advantage of convenience and efficiency many nutritionists and dietary supplement manufacturers are beginning to adopt this new technology. One notable example for Vitamin D is a Vitamin D3 Spray that you can actually spray under your tongue.
