Taking one type of vitamin D supplements it seems to cut other type levels that can be used more easily by the body, which may affect our immune system.
Our bodies create vitamin D, when UV rays in sunlight convert a protein called 7-dehydrochocholesterol into the skin into a type of vitamin D known as vitamin D3. When sunlight is separated during the fall and winter, countries like the United Kingdom We recommend taking nutritional supplements.
Two shapes of these nutritional supplements are available: vitamin D3, or Cholecalciferol – which usually comes from lanolin, a waxy substance on sheep wool – vitamin D2, or Ergocalciferol, which comes mainly from mushrooms. He thought he really did not matter anyone who took it.
But now, Emily Brown At Sari University, the United Kingdom, her colleagues conducted a compatible analysis of 11 experiments that were randomly published on vitamin D supplements, with a total of 655 participants.
They found that taking vitamin D2 supplements could lead to a decrease in the body’s concentration in vitamin D3. Why does this happen, or if vitamin D3 supplements reduce vitamin D2 levels, they are not quite clear.
Moreover, in many studies, vitamin D3 levels were less in people who take vitamin D2 than they were in control groups that did not take any vitamin D supplements. “This is an unknown effect,” says Brown.
A 2022 study indicates Vitamin D2 and D3 have overlapping roles, but they are different in supporting immune function. It seems that only vitamin D3 stimulates the type 1 interferon signal system, for example, which provides the first line of defense against bacteria and viruses.
Brown says the results indicate that vitamin D3 supplements may be more useful for most individuals than vitamin D2, but he adds personal considerations in mind, such as the desire to avoid animal products.
It also does not mean that people should stop eating vitamin D2, she says. “The level of vitamin D will remain enough if you are taking vitamin D2 supplements, but you may find that it is less effective and you may lose these additional functions in terms of immunosuppressive support.”

The plant -based vitamin D3 has begun to become easier. For example, a Tomatoes have been released to produce vitamin D3But the trials are continuing.
