All You Need To Know about Vitamin D

Vitamin D is formed by the skin’s exposure to the sun. This fat-soluble vitamin is found in dietary supplements and in some foods. The two types of vitamin D are vitamin D3 and vitamin D2.

On the other hand, vitamin D2 ergocalciferol is the type commonly used in many supplements. Vitamin D2 is used in fortifying foods including milk.

Vitamin D is necessary in maintaining the normal calcium levels and the phosphorus in our blood to sustain the mineralization of the bone as well as in improving the functions of nerves, cells and muscles.

Lack of energy, insomnia and other sleeping problems, diarrhea and nervousness are also caused by vitamin D deficiency.

People who have insufficient sun exposure are required to have more vitamin D. Moreover, people who frequently use sunscreen need vitamin D because sunscreen prevents vitamin D formation. If you have dark skin, you need to consume more vitamin D because melanin absorbs ultraviolet rays that actually lessen the ability of the skin to manufacture vitamin D.

Too much vitamin D may cause excess calcium in the blood or hypercalcemia. This may result to muscle weakness, vomiting and confusion and may lead to different complications including kidney failure and kidney stones.

You must not take vitamin D if you have sarcoidosis or hyperparathyroidism unless recommended by the doctor.

Avoid taking vitamin D and calcium together with thiazide diuretics because it may cause too much calcium levels in your body. In addition, if you are having calcium-channel blockers, you must prevent having calcium and vitamin D. You need to consult your doctor before taking these supplements.

The diagnosis is often taken over a course in order that the Ayurvedic physician determines accurately what part of the body is being affected. To diagnose problems, Ayurvedic physicians often use long questionnaires and interviews to find out a person’s dosha patterns and physical and psychological history. Ayurvedic physicians also intricately examine the pulse, tongue, face, lips, eyes, and fingernails for abnormalities that they can indicate deeper problems in the internal systems. Some physicians also use laboratory tests to assist in diagnosis.

Even statistics of World Health Organisation shows the popularity of traditional medicine, on which a significant number of population depends on Ayurvedic medicine for their primary health care.
