The Danish Health Authority recommends that all pregnant women take a daily dietary supplement with vitamin D throughout pregnancy. But several large research projects also show that it can reduce fertility in both men and women if you have a vitamin D deficiency. Therefore, many can benefit greatly from taking a vitamin supplement with vitamin D already when project baby starts.
Pharma Nord D-Pearls
D-Pearls are small, soft gelatin capsules with 20 μg vitamin D3 in each, which are produced in Denmark. The vitamin D is dissolved in cold-pressed olive oil to improve absorption. The capsules are small in size, so they are easy to swallow, but can also be chewed. Research has shown that D-Pearls have good absorption.
D-Pearls is a dietary supplement that supports teeth, bones, muscles and the immune system.
The gelatin is halal and kosher certified.
Manufactured under pharmaceutical control.
Vitamin D and female fertility
In general, approximately one in five Danes has a vitamin D deficiency in the spring, when the level is at its lowest after a long winter without sun. It can have an effect on fertility, because several large research projects have shown that it can affect fertility negatively if you have a lack of vitamin D in your body.
A study from 2019 showed that a lack of vitamin D is very common in the group of women who experience reduced fertility. In the study, 500 infertile women were examined, and here it turned out that 84% of them had a lack of vitamin D. A number that is significantly above the average woman of reproductive age.
In connection with fertility treatment, a number of studies have shown that women with a normal level of vitamin D in the blood (above 30 ng/mL or higher) have a better chance of achieving pregnancy and later avoiding miscarriage. The reason is thought to be that vitamin D affects the mucosa's receptivity to a fertilized egg. Several Danish fertility clinics therefore recommend that women undergoing fertility treatment have their vitamin D measured before starting fertility treatment. However, it is important to emphasize that no large-scale research studies and lottery trials have been carried out. Therefore, it cannot be concluded with certainty that women with vitamin D deficiency have improved fertility with vitamin D supplementation.
Vitamin D and male fertility
Research from Rigshospitalet has shown that treatment with vitamin D has a beneficial effect on sperm production in infertile men with severe vitamin D deficiency. If the man is not deficient - or only slightly deficient - in vitamin D, supplementation of vitamin D has no effect on fertility.
In the study at Rigshospitalet with the participation of 330 infertile men with vitamin D deficiency, they received either placebo medicine or vitamin D. Here, the study showed that men with reduced sperm production who received vitamin D supplements doubled the chance of spontaneous pregnancy compared to the group of men who received placebo medication. The conclusion showed that vitamin D is important for the sperm's ability to reach and fertilize the egg in the woman.
However, the study also shows that vitamin D supplementation does not increase sperm production in infertile men with only slightly reduced levels, so vitamin D supplementation is not the solution for everyone.
Vitamin D3 also contributes to maintaining:
- Teeth and bones
- The immune system
- Normal cell division
- Normal calcium level in the blood
- The uptake of calcium and phosphorus
Muscles
