Contrary to popular belief, vitamin d-2 and d-3 do not have the same nutritional value, a new study finds. As vitamin D deficiency increases, the authors call for reconsideration of official guidelines.

Vitamin D is an important nutrient that helps the intestines absorb calcium while maintaining proper concentrations of calcium and phosphate to support healthy bone growth and maintenance. If there is not enough level in the body, the bones will become brittle.

Low levels of vitamin D are also linked to a range of other diseases, including cardiovascular disease and cancer.

Vitamin D is not naturally found in many foods. Instead, most of our demand is made up of skin that is exposed to the sun’s ultraviolet rays.

Despite the importance of vitamin D, many in the United States do not have enough levels. For example, one study found that overall, more than 40 percent of the U.S. population is vitamin D deficiency. Others noted that vitamin D deficiency is an epidemic.

Moreover, in a study published in 2009, only 3% of blacks in the thousands of americans had recommended levels of vitamin D, down 9% from the previous 20 years.

For this reason, it is becoming more and more important to know how vitamins work and to ensure that the right types of supplements arrive at the most dangerous ones.

Not all vitamin D types are the same

There are two types of vitamin D, known as d-2 and d-3. The former comes from plant sources, especially fungi, and the latter comes from animal sources.

The two types of vitamin D are very similar and differ only in the structure of the side chain, which is generally considered to be quite good. In fact, on the national institutes of health website, they wrote: “these two forms are traditionally considered equivalent.

Researchers at the university of surrey in England recently set out to test whether this widely held view is correct. They wanted to know which of the two nutrients was most effective in raising vitamin D levels in the body.

The researchers measured levels of vitamin D in 335 white women in South Asia and Europe in two winters. They chose the winter, because vitamin D levels tended to decline as sunlight fell.

The women were divided into five groups: cookies, vitamin d-2; People who take vitamin d-3 in cookies; Those who take vitamin d-2 in fruit drinks; Those who take vitamin d-3 in fruit drinks; And those who received the placebo.

The study found that vitamin D-3 was twice as high in vitamin d-2 levels.

Those who participated in the d-3 cookie race increased their vitamin D levels by 74 percent, while those who received the vitamins increased 75 percent. The number of people receiving d-2 increased by 33% and 34% respectively. The placebo group fell 25 percent during the same period.

Guidelines and product changes

These findings certainly have an impact on the medical community, but they also affect the retail sector. Many companies add vitamin d-2 to drinks and foods. So some people now want to consider their options.

As the primary author Laura Mr Yanukovich (Laura Tripkovic), “said Dr.” the importance of vitamin D in our bodies cannot be underestimated, but living in the UK, from the source to adequate levels of sun in our nature is very difficult, so we must know through our food supplement. “The same is true in many parts of the United States

She continued: “our findings show that vitamin D – 3 in improving the effect of vitamin D levels in the body is D – 2 two times, so now people are thinking about the two types of vitamin D.

“By fish, eggs, or vitamin D – 3 D – supplement consumption 3 people than vitamin D – 2 rich food, such as mushrooms, vitamin D – 2 – strengthening bread or contain vitamin D supplements of 2, help to improve their long-term health. ”

Vitamin D deficiency seems to be common, and as more and more research is carried out, it is becoming increasingly clear that this lack of nutrients has a significant impact on the health of the country as a whole. Such studies may play a role in raising awareness and eventually reverse this trend.

Understanding how to use sunscreen can lead to vitamin D deficiency.
