Vitamin D: when to supplement?

Vitamin D, essential for the body

Let's start with the beginning. What is vitamin D? "Vitamin D is a vitamin naturally synthesized by the body when it is exposed to the sun", explains Raphaël Gruman, dietician-nutritionist. It is involved in a number of essential processes for good health. Namely, it strengthens the immune system, helps to fix calcium on bones, has an action on fatigue and mood and improves muscle strength. Several studies also demonstrate its preventive action against certain cancers. You will understand, it is therefore essential for the body.

So when the sun goes out, at the end of September, and until it comes back, around March, we have to supplement ourselves to make sure we do not develop deficiencies. In the program : "absorb one ampoule of vitamin D every three months and put three drops of liquid food supplement on his tongue every morning", recommends Raphael Gruman. And that, we told you, until the sunny days come again.

Vitamin D deficiencies: who are the most at risk?

"In winter, almost all French are deficient in vitamin D", indicates the professional, who advises everyone to follow a cure (knowing that there are no contraindications, apart from overdose, very rare). Everyone, but especially children, because it promotes the absorption of calcium and contributes to the mineralization of the skeleton, but also to menopausal women. And for good reason, "a good level of vitamin D provides active protection against osteoporosis"he observes.

Vitamin C, the other ally of winter

What about other vitamins that could help us cope with winter? "You can also bet on vitamin C", according to the professional. Powerful antioxidant, it strengthens the immune system.

If in theory, we find enough in our diet to not need to do specific cure, Raphael Gruman recommends it."Vitamin C is very fragile Concrete example: take an orange that contains vitamin C. Cut in half, it will have already lost almost half of its content.he says. This is the reason why he also advises in winter cure. Here, no drops to be taken every day or blisters every three months, the dietician-nutritionist recommends a capsule of acerola (dietary supplement from fruit very rich in vitamin C) every morning for two weeks. A health cure to be repeated twice during the winter.
