One of the signs of insufficient vitamin D levels can be frequent illness. Vitamin D levels in the body can be determined by a blood test.

One of the factors that has the greatest effect on vitamin D levels is exposure of bare skin to sunlight. Anything that limits the amount or quality of sunlight can compromise vitamin D levels. The formation of vitamin D from the sun is also affected by latitude and skin color. Production in the autumn and winter months is insufficient. Vitamin D is difficult to obtain through diet because very few foods naturally contain vitamin D. The exceptions are the liver of fatty fish such as salmon, sardines, herring, and red meat. For this reason, supplementation should be an almost essential part of every individual's life. At least in the autumn, winter and spring months.

Vitamin D has countless positive effects on the body. Thus, for example, it contributes to the normal function of innate and adaptive immunity and affects the likelihood of common diseases. [1] In athletes, studies have examined the effect on sports performance, strength and muscle performance parameters. [2] Other studies show the effect of vitamin D on testosterone levels. [3]

Vitamins D3 and K2 go hand in hand in the body. As is known, vitamin D regulates the metabolism of calcium and phosphate in the body, and K2 contributes to the normal state of bones. Without enough K2, calcium can build up in the blood with higher doses of vitamin D3.

Yes you can. Experts agree that a large part of the population is deficient in vitamin D, so supplementing it can be an important aspect for health.
