Essential for bone strength, immunity, and calcium absorption, vitamin D plays a central role in maintaining our body’s balance. However, many people are deficient in it, especially in the winter or when they don’t get enough sun exposure. At Soin-et-Nature, we’ve curated a selection of high-quality products—drops, capsules, tablets, and vials—to help you address these common deficiencies and support key physiological functions at every stage of life, from bone development to the body’s natural defenses.
More detailsVitamin D is fat-soluble, meaning it dissolves in fats. It exists in two forms:
The animal-derived vitamin D found in vitamin supplements comes from lanolin, a naturally occurring substanceobtained after shearing sheep, from raw wool washed with soap and soda.
Vitamin D helps maintain normal bone health; in fact, it helps calcium bind to bones, promoting a stronger skeletal system. It also ensures proper muscle function.
Finally, Vitamin D helps stimulate the activity of white blood cells responsible for the body’s defense, thereby boosting the body’s immune response.
Developed by Santé Verte, two drops of Vitamin D3 400 IU provide 400% of the recommended daily intake of Vitamin D3.
Vitamin D3, also known as cholecalciferol, plays a crucial role in several bodily functions. Here’s how vitamin D3 can benefit your health:
Santé Verte Vitamin D3 400 IU is a natural option to ensure an adequate intake of vitamin D3, which is essential for your health.
Vitamin D, or calciferol, is afat-soluble vitamin(soluble in fats: lipids). It is a hormone found in food and synthesized in the upper layers of the human skin from a cholesterol derivative when exposed to the sun’s UVB1 rays. Theoretically, sun exposure provides 80 to 90 percent of the necessary vitamin D intake, with diet providing the remaining 10 to 20 percent.
In humans, it exists in two forms: D2 (ergocalciferol), produced by plants, and D3 (cholecalciferol), of animal origin.
Over-the-counter vitamin D is the quintessential anti-rickets vitamin. It is essential for bone growth and contributes to the proper functioning of our immune system.

Vitamin D may play a protective role against severe forms of COVID-19, a new infectious disease caused by the SARS-CoV-2 coronavirus. As such, it can be taken as a preventive measure. According to the National Academy of Medicine: Vitamin D “plays a role in regulating and suppressing the cytokine-mediated inflammatory response that causes acute respiratory distress syndrome, which characterizes the severe and often fatal forms of COVID-19.” (source: press release).

Furthermore, a recent French scientific study (1) has shown that the majority of the French population needs vitamin D supplementation. Changes in dietary habits over the past several decades are responsible for this finding: the modern diet no longer provides sufficient vitamin D to meet our bodies’ needs.

Deficiency is observed in some young children, as well as in older adults who no longer get enough sun exposure.
7-dehydrocholesterol is a lipid found in the skin that is converted into vitamin D by sunlight, specifically UVB rays. It is important to note that sunscreens absorb a very large amount of these UVB rays, which significantly reduces vitamin D synthesis, as well as melanin (tanning), which acts as a barrier to this synthesis. Conclusion: Sun exposure while wearing sunscreen does not provide sufficient vitamin D. However, it is still important to protect yourself from the sun to prevent skin cancer.
Vitamin D deficiency can cause:
Vitamin D3 helps maintain ahealthy immune system.Vitamin D3 is also known as the “sunshine vitamin,” as the body synthesizes it during sun exposure; therefore, it is important to take supplements in the winter because we quickly become deficient. Vitamin D3 plays an important role in bone health by preventing fractures and supporting proper development in children. Vitamin D3 promotes the body’s absorption of calcium and contributes to healthy teeth.
Hypervitaminosis, on the other hand, can cause:
It is found primarily in the following food sources:

Vitamin D experts do not recommend a specific time of day to take them. However, a 2014 study in the Journal of the Academy of Nutrition and Dietetics* showed that taking vitamin D3 supplements with a meal can help with 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 it dissolves in fat. The absorption process is similar to that of dietary fats. In fact, the digestion of fat stimulates bile secretion, promoting the formation of micelles—small structures that transport the fat and vitamin D3 to the intestinal absorption surface, facilitating their absorption,” explains Dr. Bess Dawson-Hughes, a scientist at the USDA Human Nutrition Research Center on Aging at Tufts University (USA) and author of this study.
It is therefore strongly recommended to take vitamin D with a meal to facilitate its absorption.
