Vitamin C also contributes to normal energy-yielding metabolism, and vitamin D to the maintenance of normal bones and normal muscle function. In addition, the formula contains shiitake, ginseng and echinacea extracts.
Take 2 capsules per day with a glass of water; a bottle of 60 capsules lasts 30 days. Do not exceed the recommended daily dose. Do not use in case of known allergy to any of the ingredients. Not recommended for children, pregnant or breastfeeding women. Keep out of reach of young children. Food supplements are not a substitute for a varied and balanced diet and a healthy lifestyle.

Vitamin C, vitamin D and zinc contribute to the normal function of the immune system. Vitamin C also contributes to the reduction of tiredness and fatigue, to normal energy-yielding metabolism, to the normal functioning of the nervous system, to normal psychological function, to the protection of cells from oxidative stress and to normal collagen formation for the normal function of skin; it increases iron absorption. Vitamin D also contributes to the maintenance of normal bones, normal teeth and normal muscle function, and to normal absorption and utilisation of calcium and phosphorus. Vitamin D helps reduce the risk of falling associated with postural instability and muscle weakness. Falls are a risk factor for bone fractures in men and women aged 60 and over. Zinc also contributes to the protection of cells from oxidative stress, to normal cognitive function, to the maintenance of normal skin, normal hair, normal nails and normal bones, and to normal acid-base metabolism. Two capsules provide 40 mg of vitamin C (50% NRV), 20 µg of vitamin D (400% NRV) and 5.3 mg of zinc (53% NRV).

Immun+ D3 from Bio-Gestion combines vitamin D3, vitamin C from acerola and zinc with plant ingredients such as shiitake and echinacea, in a formula designed to support the normal function of the immune system.

Immun+ D3 brings together three micronutrients that contribute to the normal function of the immune system: vitamin D3, at 20 µg a day, vitamin C from acerola, and zinc. We have added three long-known plants: shiitake, ginseng and echinacea. Two capsules a day, especially during the months when the days grow shorter.

Let us start with vitamin D, the most unusual of the three.

The sunshine vitamin… in short supply in winter

Vitamin D has a special feature: our skin makes it itself, under the effect of the sun’s UVB rays. Hence its nickname, the “sunshine vitamin”. But at our latitudes, from October to March, the sun is too low in the sky for this production to be significant. And food provides little of it: it is found mainly in oily fish, eggs and certain mushrooms.

This is why the Federal Commission for Nutrition recommends an intake of 15 µg a day up to the age of 60, and 20 µg beyond. Immun+ D3 provides 20 µg, as vitamin D3 (cholecalciferol).

Immun+ D3 from Bio-Gestion naturally finds its place in the winter routine, when sunlight becomes scarcer and the body’s natural synthesis of vitamin D decreases.

For people aged 60 and over

Vitamin D helps to reduce the risk of falling associated with postural instability and muscle weakness. Falling is a risk factor for bone fractures among men and women 60 years of age and older.

The beneficial effect is obtained with a daily intake of 20 µg of vitamin D from all sources.

Vitamin D

  • Vitamin D contributes to the normal function of the immune system.
  • Vitamin D contributes to the maintenance of normal bones.
  • Vitamin D contributes to the maintenance of normal muscle function.
  • Vitamin D contributes to normal absorption/utilisation of calcium and phosphorus.

Vitamin C from the West Indian cherry

Acerola (Malpighia emarginata), also called the West Indian cherry or Barbados cherry, grows in gardens in the Caribbean and Central America. It looks like a small, shiny cherry, but its taste is distinctly sour: it is one of the richest fruits in vitamin C in the world, far richer than the orange.

In Immun+ D3, the vitamin C comes from an acerola juice dry extract, at 40 mg a day, i.e. 50% of the NRV.

  • Vitamin C contributes to the normal function of the immune system.
  • Vitamin C contributes to the reduction of tiredness and fatigue.
  • Vitamin C contributes to normal functioning of the nervous system.
  • Vitamin C contributes to the protection of cells from oxidative stress.

Acerola (Malpighia emarginata), a small shrub laden with red fruit, is renowned for its cherries, naturally very rich in vitamin C, from which the extract used in Immun+ D3 is obtained.

Zinc, a trace element with many roles

The body has no real store of zinc: it depends on a regular supply from food, notably meat, seafood, dairy products and wholegrain cereals. Immun+ D3 provides 5.3 mg a day, i.e. 53% of the NRV.

  • Zinc contributes to the normal function of the immune system.
  • Zinc contributes to the protection of cells from oxidative stress.
  • Zinc contributes to normal cognitive function.
  • Zinc contributes to normal acid-base metabolism.
  • Zinc contributes to the maintenance of normal bones.

Three ingredients from far away

Shiitake. Its Japanese name says everything about how it is grown: take means mushroom, and shii refers to the tree on whose wood it traditionally grows, an Asian cousin of the chestnut. In China, it has been cultivated on logs for nearly a thousand years. Today it is one of the most widely eaten mushrooms in the world. Immun+ D3 contains 134 mg of shiitake dry extract a day.

Ginseng. This root is one of the most famous plants of the Korean and Chinese tradition. It grows slowly, in the shade, and it takes several years before it can be harvested. Immun+ D3 contains 125 mg of ginseng root dry extract (Panax ginseng) a day.

Shiitake, traditionally grown on hardwood logs, is a mushroom native to Asia that is now among the most widely eaten in the world.

Echinacea. Its name comes from the Greek echinos, the hedgehog, because of its domed, prickly centre. Native to the prairies of North America, it was used there by Indigenous peoples long before it crossed the Atlantic. Today it is a popular garden plant, grown for its large purple flowers, which bees and butterflies love. Immun+ D3 contains 100 mg of echinacea dry extract a day.

Purple coneflower, with its large flowers visited by bumblebees, is a plant native to the prairies of North America, now widely grown for its distinctive blooms.
