Jaké jsou výhody vitaminu D3?

Vitamin D3 (Cholecalciferol), also referred to as the sunshine vitamin, is synthesised from the skin when it’s exposed to sunlight. Other sources of the vitamin are fatty fish such as sardines, salmon and tuna. Fish products like cod liver oil also supply the body with this vital nutrient. Vitamin D3 plays an significant role in the body and has an effect on many critical functions.

It might also have a role in the prevention of several diseases. Here are some of the advantages of vitamin D3. Correct functioning of the nervous system, bone development and maintaining optimum levels of bone density requires calcium levels in the blood to be kept within a small variety. Vitamin D3 plays an important part in how our body uses Calcium. D3 has a substantial influence on the immune system. It may enhance immunity and increase our immunity to diseases. It might also prevent autoimmunity, a condition in which our immune system turns against our own body and damages it.

Vitamin D

It’s true that vitamin D levels have a substantial influence on blood pressure. Although optimal levels of D3 reduces the risk of hypertension, more studies need to establish whether it’s beneficial for normalising blood pressure in patients with hypertension. In its active form, vitamin D plays a role in insulin secretion once the body needs a greater quantity of insulin. Studies indicate that lower than optimal levels of vitamin D can impair insulin secretion. It might also have a function in type 2 diabetes.

More research must establish the actual effects of vitamin D levels on insulin and its role in diabetes or its avoidance. Research suggests that a lack of D3 has a part to play in certain health conditions and restoring adequate levels of vitamin D can reduce the strength of the condition in some instances. An extreme lack of vitamin D leads to diseases like osteomalacia and rickets.


It is another condition where inadequate vitamin D may play a role. Generally, osteoporosis is due to calcium deficiency. This may be caused due to insufficient calcium in the diet. However, vitamin D is instrumental in absorption of calcium from the body and a deficiency may lead to impaired calcium absorption. Sufficient levels of D3 in our body will aid in the development of strong bones, which in turn will stop the progression of osteoporosis as we age. Women, people that cannot walk and patients who experience steroid treatment are prone to osteoporosis as they grow older.


Autoimmune diseases are caused when our immune system, which fights diseases, turns against our own body cells. Examples of these diseases are multiple sclerosis, rheumatoid arthritis and diabetes mellitus. Although not conclusively proven, studies indicate that sufficient vitamin D intake may lessen the odds of autoimmune diseases. Adequate levels of vitamin D3 is extremely vital for our health. Deficiency of vitamin D is regarded as one of the principal causes for many different disorders and diseases. People who do not get adequate exposure to sunlight and do not eat foods rich in vitamin D are likely to have a lack of this vital nutrient. Some of the consequences of vitamin D deficiency surface only later in life in which time it’s usually too late.
