What are the uses of Vitamin D?
Vitamin D is what is called a steroid vitamin, which in turn belongs to a group of fat-soluble prohormones. These are metabolic precursors which the body transforms into active hormones and they aid the absorbing and metabolic support of the minerals of calcium and phosphorus, which are required to keep the teeth in good health and the bones strong. Those who are exposed to regular amounts of the sun’s rays have no need for D vitamin supplements due to the fact that sunlight boosts an adequate synthesis of this vitamin within the skin. Along with sunlight and supplements, this nutrient can also be obtained from food.
Which are the sources of this vitamin?
This vitamin is the only nutrient of all the vitamins which is obtained through the skin, via sunlight and as a reaction to it. Vitamin D is also found in a small number of foods, such as oily fish (sardines and salmon), powdered milk, fortified fat spreads, and eggs.
What happens when there is an extreme lack of this vitamin?
The problems associated with an extreme D vitamin deficiency usually occur as a consequence of low calcium levels in the blood. If this should happen, a health care provider or physician could suggest a prescription of capsules containing D vitamin 50 000 Units.
The symptoms and warning signs which may indicate a severe vitamin D deficiency can include the following:
- Thinning of the bones or osteomalacia (occurring only in adults)
- Severe fatigue
- Rickets (An illness of reduced bone growth and abnormal growth in the arms and legs that occurs only in children.)
- Osteoporosis in older women
It is up to the professional (physician or pharmacist) to determine if a deficiency of vitamin D is to blame for the health problem or the low levels of calcium. If this is indeed the case, the patient may be provided with the very potent prescription or treatment of 50 000 units of vitamin D. It is par for the course, though it still must be said that this medicine must be used with caution. Why? The answer is simple: due to the fact that this dosage is far beyond the usual or normal vitamin supplement dosage.
Which are the potential consequences of an overdose of this vitamin, or even toxicity?
The symptoms can be vomiting, nausea, nervousness and general weakness. If this is experienced, a doctor must be consulted at once.
Why must we be careful when reading the prescription for this dose of vitamin D?
The prescription for the D Vitamin 50 000 Unit tablets or capsules will be clear as to the frequency and the duration of ingesting the capsules. This very well may be one capsule a day, or perhaps every second day. Also, it is very important not to go over what the physician recommends.
Also, the prescription is likely to indicate that the medication or treatment is to be taken only for a limited period of time. The most common course of therapy continues for no more than a few weeks until the physician re-evaluates the health condition of the patient. In many cases, the body has managed to build up proper reserves of this vitamin D and as a consequence, the dosage may be considerably cut down.
But, this is a very high dosage of vitamins, so if you are worried, consult your physician or pharmacist, who are sure to give you the proper advice and suggest any alternatives in the case that you develop some unwanted symptoms. Take care to use the vitamin D 50 000 units tablets or capsules with caution.
