Vitamin D, also known as calciferol, is a collective term for all cholecalciferol bioactive sterols. It is also a class of fat-soluble vitamins, which are steroid compounds. Among the vitamins required by humans, vitamin D is very special. It is a precursor of hormones. And when people are exposed to the sun for 10 minutes a day, the body itself can synthesize enough vitamin D3. The best evidence that vitamin D is good for the body is good for bones and reduces mortality in older women.

If the sunshine time is sufficient, under normal circumstances, the amount of vitamin D required by the human body can be 10-80%. But in addition to relying on the sun to receive ultraviolet light, food is another source of vitamin D. There are two kinds of vitamin D from food. Usually, the plant source is vitamin D2 (Egocalciferol), and the animal source is vitamin D3 (Cholecalciferol).

Vitamin D nutrition effect

Activated vitamin D promotes calcium absorption in the small intestine. Maintain proper levels of calcium and phosphorus. It allows mineralization of the bones to be normal. It also prevents muscle twitching caused by hypocalcemia. When the body’s vitamin D is insufficient, the bones become thinner, brittle or deformed. Sufficient vitamin D can prevent rickets in children. And osteoarthritis in adults. Vitamin D and proper amount of calcium protect the elderly and prevent osteoporosis.
In addition to its role in calcium, vitamin D has other uses. Contains prevention of cardiovascular disease, cell growth, regulation of neuromuscular and immune functions, and reduced inflammatory response.

How much should I add to my daily vitamin D?

An average of 400-800 IU per day, or 10-20 micrograms, is sufficient for individual needs.

Infants under 12 months: 400 IU
Children and adolescents: 600 IU
Adults under 70: 600 IU
Adults over 70 years old: 800 IU
Pregnant or lactating women: 600 IU
According to the Institute of Medicine, 4000 IU is the safe upper limit for daily vitamin D intake in adults. The current daily dose of up to 10,000 IU has not been shown to be toxic to healthy individuals.

However, 40,000 to 100,000 IU (1000-2500 micrograms) of daily intake for more than one month or longer has been shown to be toxic to humans. When the 25(OH)D content is too high, this causes an increase in the amount of calcium in the blood, resulting in hypercalcemia.

Studies have found that daily supplementation with vitamin D has a positive effect on muscle function, and this effect is more pronounced in elderly people who are deficient in vitamins. Continuous supplementation of 1,000 IU of Vital D per day is sufficient, but it will lose its effect on and off.
