There are dozens of different vitamin D brands on the market – but only few can document that they work. Several exciting science projects involving vitamin D are in the pipeline or have already been completed. Some of these studies show which supplements are actually able to increase levels of the “sunshine nutrient” in the body.

A recent study published in Nutrients* describes how a group of 43 people got D-Pearls with 40 micrograms of vitamin D, while another group got matching placebo. The study was carried out by Norwegian and American scientists.

At the beginning of the study, which was in the spring, both groups had approximately the amount of vitamin D in their blood. Their levels were around 60 nmol/L and that is considered adequate.

Levels typically drop during the winter period

Over the course of winter, levels of vitamin D in the body typically drop. This is because the sun does not sit sufficiently high in the sky to enable our skin to synthesize vitamin D with help from the sunrays. Besides, the amount of vitamin D that we get from our diets is too small to compensate for the nutrient deficiency caused by our lack of sunlight in the winter time.

Not surprisingly, the participants in the placebo group in the above-mentioned study had predictably low vitamin D levels in their blood as spring approached. On average, their levels had dropped to 47 nmol/L.

D-Pearls optimized their vitamin D status

Things looked different for the group of participants that got the 40 microgram D-Pearls supplement every day for the full five-month duration of the study. Their vitamin D levels went up to 75 nmol/L on average, which is what health authorities regard as optimal.

The study also revealed that the D-Pearls supplement has good bioavailability and effectively raises levels of vitamin D in the blood even though it is winter and the sun is too weak to produce the vitamin.

D-Pearls contains natural vitamin D3 in an olive oil formula in gelatin capsules. The oil helps increase the body’s absorption of the lipid-soluble nutrient – and the small capsules are easy to swallow or chew.

D-Pearls comes in different strengths, which enables you to choose the right dose to match the season and your personal needs.

Governments to dole out free vitamin D to millions of vulnerable citizens

Increasing the vitamin D blood levels of vulnerable groups in the population has been given that high priority in England and Scotland that the governments in both nations have decided to hand out free vitamin D supplements to selected citizens for the next four months.

In England alone, this will amount to 2.5 million people, all of whom are at risk of becoming vitamin D-deficient over the course of the winter period. The authorities have decided that these individuals will fare better with a free supplement.
