Wrongly Choose Vitamin D Supplements Can Have An Impact On The Body, Here Are The Latest Findings

JAKARTA – Many people take vitamin D supplements to maintain endurance or bone health. However, not a few are mistaken in choosing the right type of vitamin D. Mistakes in choosing supplements, especially between vitamin D2 and D3, can actually affect their effectiveness in the body.

A joint study from the University of Surrey, John Innes Center, and the Quadram Institute Bioscience revealed that the selection of vitamin D supplements has a significant impact on the levels of vitamin D in the blood. The results of this study were published in the journal Nutrition Reviews and quoted from Eating Well.

In the study, the researchers traced various studies published in PubMed between January 1975 and February 2023. Of the 202 articles reviewed, only 11 random controlled trial studies met the criteria for in-depth analysis.

Each study involved participants who were randomly asked to take vitamin D2 or not at all. Scientists then compared the levels of vitamin D3 in the blood before and after giving supplements to see how they affect the body.

The results showed that those who consumed vitamin D2 experienced a significant decrease in vitamin D3 levels compared to other participants. On average, levels of vitamin D3 serum decreased by about 18 nanomols per liter at the end of the study, and about 9 nanomols per liter when calculated based on overall changes during trials.

This finding indicates that the consumption of vitamin D2 can reduce levels of D3 in the body, so that both forms of vitamins cannot be considered to have the same function. According to the researchers, although D2 is able to increase the total level of vitamin D, the effect is not as effective as D3 in maintaining long-term stability.

Researchers explain vitamin D3 may be a more optimal choice for most people. However, they emphasized the importance of further research to understand more deeply how this interaction between the two types of vitamins occurs.

Sources of vitamin D themselves can be obtained from food, although the number is limited. Fat fish such as salmon, sardines, and macachel are the best natural sources, followed by egg yolks, beef livers, and UV light-exposed mushrooms. In addition, some food products such as milk, yogurt, and breakfast contracts have also been strengthened by vitamin D to help meet daily needs.

For those who have difficulty meeting the vitamin D needs of food, consultation with medical personnel is highly recommended before starting to take supplements. Now, there are even plant-based vitamin D3 made from crustal moss (lichen), so it is safe for those who undergo a vegan diet.

This finding reinforces the results of previous studies showing vitamin D3 is more effective in maintaining vitamin D levels in the body than D2. The decrease in D3 due to D2 consumption is a signal that both cannot be exchanged freely.

Until the mechanism is certainly understood more deeply, experts suggest that people choose vitamin D3 as the main supplement, while still consulting health professionals to ensure that doses and types are most appropriate to the needs of the body.
