Vitamin D is fat-soluble, meaning it dissolves in fats. It exists in two forms:
The animal vitamin D found in dietary supplements is derived from lanolin, a naturally-occurring substance obtained after sheep shearing, from raw wool washed with soap and soda.
Vitamin D contributes to the maintenance of normal bone structure, helping to bind calcium to the bone for greater skeletal strength. It also ensures good muscle function.
Finally, Vitamin D helps stimulate the activity of the white blood cells responsible for defending the body, thereby boosting the body's immune system.

Santé Verte Vitamin D3 400UI is a natural option for ensuring an adequate intake of vitamin D3, essential to your health.
Vitamin D or calciferol is a fat-soluble vitamin. It is a hormone found in food and synthesized in the upper layers of the human epidermis from a cholesterol derivative under the action of the sun's UVB1 rays. Theoretically, exposure to the sun provides 80-90% of vitamin D requirements, with the remaining 10-20% provided by diet.
In humans, vitamin D exists in two forms: plant-produced D2(ergocalciferol) and animal-produced D3(cholecalciferol).
Over-the-counter vitamin D is the ultimate anti-rachitic vitamin. It's essential for bone growth and helps our immune system function properly.

Vitamin D may have a protective role against severe forms of Covid-19, a new infectious disease linked to the SARS-CoV-2 coronavirus. As such, it can be taken as a preventive treatment.

A recent French scientific study (1) showed that the majority of the French population needed vitamin D supplementation. Changes in dietary habits over the last few decades are responsible for this finding: modern diets no longer provide sufficient quantities of vitamin D to meet our body's needs.
(1) According to the results of theINCA 2 study (Etude Individuelle Nationale des Consommations Alimentaires 2-2006-2007). ANSES, 2015 (Saisine n°2012-SA-0142).
Its deficiency is observed in some young children, but also in elderly subjects who no longer expose themselves to the sun.
7-dehydrocholesterol is a lipid substance found in the skin which is converted into vitamin D by sunlight, particularly UVB rays. It's important to know that sunscreens absorb a very large quantity of these UVBs, which greatly reduces vitamin D synthesis, as well as the melanin (tanning) that acts as a barrier to this synthesis. Conclusion: exposure to the sun with sunscreens does not replenish the vitamin D dose. Nevertheless, we must protect ourselves from the sun to avoid skin cancer.
Vitamin D deficiency can lead to
Vitamin D3 helps maintain the immune system. Vitamin D3 is also known as the sunshine vitamin, because the body synthesizes it during exposure to the sun, so in winter it's important to take supplements, as we quickly become deficient.

Vitamin D specialists don't recommend a specific time to take it. However, a 2014 study in the Journal of the Academy of Nutrition and Dietetics* showed that supplementing vitamin D3 with a meal can help the absorption of this vitamin. This study shows that vitamin D absorption is greater when the dietary supplement is taken with a meal containing fatty acids (preferably of plant origin).
"Vitamin D3 is a fat-soluble vitamin, which means that it dissolves in fat. The absorption process is similar to that of dietary fats. In fact, digestion of a fatty substance stimulates the secretion of bile, promoting the formation of micelles, small structures which transport this fatty substance and vitamin D3 to the intestinal absorption surface , thus promoting their assimilation ", explains Dr. Bess Dawson-Hughes, Scientist at the USDA Human Nutrition Research Center on Aging at Tufts University (USA), author of this study.
It is therefore strongly recommended to take vitamin D with a meal, to facilitate its absorption.
