A good healthy body needs a healthy diet; which contains all essential minerals and vitamins. It is a known fact that our body doesn’t produce vitamins or minerals of its own; that’s why it is necessary to take them from external sources like food, supplements, etc. In that list of essential vitamins; vitamin D has an imperative role to play.

About Vitamin D

Vitamin D is a very essential vitamin; which is also a fat-soluble vitamin. It is naturally present in some food items. Other than the food you can also take supplements to fulfil your vitamin D deficiency. The production of vitamin D also happens when ultraviolet rays from the sunlight strike the surface of the skin and trigger the vitamin D synthesis.

The vitamin D that you get from sunlight exposure, supplement and foods go through two hydroxylations in the body; since they are biologically inert. The first process of hydroxylation occurs in the liver; which converts it into 25 hydroxyvitamin D, also known by the name calcidiol. The second process of hydroxylation takes place in the kidney; that helps in forming the physiologically active 1, 25 dihydroxy vitamin D, also known by the name of calcitriol.

Another major benefit of vitamin D is that it helps in promoting calcium absorption in the gut to maintain proper phosphate and serum calcium concentrations for normal bone mineralization. It helps in preventing the problem of hypocalcemic tetany. It is a health disorder in which involuntary contraction of muscles happens; which lead to spasms and cramps. It is very important for bone remodelling and bone growth.

To reduce the risk of rickets in children and osteomalacia in adults; the addition of a sufficient amount of vitamin D in the diet is necessary. It also has a key role in the body to reduce inflammation. The modulation process of neuromuscular, immune function, glucose metabolism and cell growth is also supported by Vitamin D.

Health Risks of Excess Vitamin D Intake

The excess of anything is erroneous and always causes certain problems. The same goes with excess vitamin D intake. The excess vitamin D can be toxic for the body. As you know it helps to increase calcium absorption in the gut. But with its excess amount you can have hypercalcemia; it is a disorder in which the amount of calcium in the body goes beyond the normal range. It can lead to health issues like muscle weakness, kidney stones, excessive thirst, vomiting, nausea, pain, loss of appetite, polyuria and dehydration.

The excess of vitamin D can also possibly cause precarious health conditions like renal failure, calcification of soft tissues throughout the body; that includes the heart valves and coronary vessels. This condition may cause cardiac arrhythmias and can even lead to death.
