- Taking vitamin D2 can reduce the vitamin d3 mirror, which indicates that the two forms are not interchangeable.
- Vitamin D3 appears more effective for maintaining a healthy vitamin -D mirror in the body.
- Of course, only a few foods contain vitamin D, so that the food or nutritional supplements that are still attached are still required.
Millions of people occupy vitamin D to support bone and immuneism – but new research results indicate that the way they choose could make a surprising difference.
A team of British scientists checked data from clinical studies and found that vitamin D2-die vegetable version, which is often found in enriched foods and some nutritional supplements, is actually lower vitamin D3 values, the shape of its body naturally out of sunlight.
Vitamin D helps your body absorb calcium, keep the bones strong and to support a healthy immune system. Because many people don’t get enough of sunlight – especially in autumn and winter – supplements are often recommended.
The new findings, published in Nutritional ratingsPut new questions about whether the two versions of vitamin D are interchangeable. Let us break down what the researchers have found.
How was the study carried out?
In order to investigate how vitamin D2 could have a vitamin D3 mirror, researchers from the University of Surrey, the John Innes Center and the Quadram Institute Bioscience are searched for the PubMed database for studies that were published between January 1975 and February 2023. They found 202 articles and narrowed them to 20 that met their criteria. In the end, the researchers included 11 studies in their detailed statistical analysis.
Each study was a randomized controlled study, which means that the participants randomly take vitamin D2 or not. The researchers compared the vitamin D3 mirror in the blood before and after supplementation to see how they have changed. This approach showed whether a consistent pattern occurred in the studies -in this case whether the intake of vitamin D2 influenced the vitamin -d3 mirror in the body.
What did the study find?
People who took vitamin D2 nutritional supplements saw a noticeable decrease in vitamin D3 level compared to those who did not do it. On average, the serum levels of vitamin D3 fell by about 18 nanomol per liter and about 9 nanomol per liter by the end of the investigation period if the researchers examined the overall change during the tests.
Since this pattern has been shown in several randomized controlled studies, the results indicate a real cause-effect connection. The completion of vitamin D2 seems to reduce the vitamin D3 level in the body.
The researchers say that more work is necessary to understand exactly how this happens, but the results contribute to the growing proof that vitamin D3 can be the better option for most people when choosing an addition.
How does that apply to real life?
If you take a vitamin -D supplement, this examination shows that the type you choose is really important. Both D2 and D3 can increase the total vitamin -D mirror, but D3 seems to make it better to keep these values ​​stable and support their health in the long term.
You can also get vitamin D from food, although natural sources are limited. Fatfish fish such as salmon, mackerel and sardines are among the best options, together with egg yolk, beef lover and mushrooms that are exposed to UV light. Many everyday foods such as milk, plant-based milk, yogurt and breakfast cereals are attached to close the gap-but it can still be difficult to meet daily needs by nutrition alone. If you are concerned about reaching your target, you should talk about an addition to a health profession. You may even have a recommendation for you, which you can snap at the pharmacy or in the grocery store.
And for everyone who follows a vegan or herbal diet, there is good news: Vegan vitamin D3 from lichen-one natural, non-changing source is available and works more like traditional D3.
Our expert
This research complements what smaller studies have indicated for years: Vitamin D3 seems to be the more effective form of vitamin D for maintaining healthy mirrors in the body. The consistent waste of D3, which is observed according to the D2 supplementation, suggests that the two forms do not work in the same way and should not be treated as interchangeable. While D2 can still increase the entire vitamin D to a certain extent, this analysis can also lead to D3 levels fall. Until researchers understand why this happens, it makes sense to look at D3 more reliably for most people. Talk to a medical specialist if you consider to start a vitamin -D supplement or ask yourself whether you take the right thing for your needs.
