INGRÉDIENTS ET PRÉPARATION
- Amasser 24 à 36 coquilles d’œufs et les rincer à l’eau.
- Retirer le blanc qui pourrait être resté coincé, mais sans retirer la membrane, car elle contient des éléments nutritifs supplémentaires.
- Faire bouillir 6 à 8 tasses d’eau filtré dans un.
- Déposer soigneusement les coquilles d’œufs dans l’eau afin d’éliminer tous les pathogènes nuisibles.
- Laisser bouillir pendant 10 à 15 minutes.
- Égoutter les coquilles.
- Répartir les coquilles sur une plaque à cuisson en acier inoxydable et laisser sécher à l’air ambiant.
- Déposer ensuite les coquilles et la plaque dans le four à 200 degrés (Fahrenheit) pendant environ 10 minutes pour sécher complètement.
- Après séchage, mettre quelques coquilles dans un moulin à café jusqu’à ce qu’elles soient complètement pulvérisés en une forme granulaire poudreuse fine.
- Conserver au réfrigérateur dans un pot Masson hermétiquement fermé loin de la chaleur ou de l’humidité.
CONSOMMATION
1 c. à thé contient environ 800 à 1000 mg de calcium carbonate. Consommer avec les repas. Vous pouvez l’incorporer à un verre d’eau. Ne consommez pas plus d’une cuillère à thé par jour, puisqu’il peut irriter votre système digestif.

Egg-shell calcium (Ca) is one of the effective Ca sources for bone metabolism. In the present study, we investigated whether egg-shell Ca had similar effects compared with calcium carbonate (CaCO3) when vitamin D3 (1alpha(OH)D3) treatment was given to an osteoporotic rat model. In both 1alpha(OH)D3-supplemented and -unsupplemented rats, the bone mineral density (BMD) of the lumber spine in the vitamin-supplemented group increased significantly compared with the unsupplemented group. In a Ca balance study, there were also significant differences in intestinal Ca absorption, urinary Ca and fecal Ca between the vitamin-supplemented and -unsupplemented groups. These results show that egg-shell Ca could have similar effects to CaCO3 on bone metabolism. In contrast with CaCO3, vitamin D3 supplementation did not significantly increase serum Ca levels in the egg-shell Ca group; however, the mechanism of Ca absorption is still unclear. Our results suggest that egg-shell Ca may be an effective nutrient in Ca metabolism for people treated with vitamin D3.

Rovenský J1, StancÃková M, Masaryk P, SvÃk K, Istok R. In this paper the most significant biological and clinical aspects of a biopreparation made of chicken eggshells are reviewed. Eggshell powder is a natural source of calcium and other elements (e.g. strontium and fluorine) which may have a positive effect on bone metabolism. Experimental and clinical studies performed to date have shown a number of positive properties of eggshell powder, such as antirachitic effects in rats and humans. A positive effect was observed on bone density in animal models of postmenopausal osteoporosis in ovariectomized female rats. In vitro eggshell powder stimulates chondrocyte differentiation and cartilage growth. Clinical studies in postmenopausal women and women with senile osteoporosis showed that eggshell powder reduces pain and osteoresorption and increases mobility and bone density or arrests its loss. The bioavailability of calcium from this source, as tested in piglets, was similar or better than that of food grade purified calcium carbonate. Clinical and experimental studies showed that eggshell powder has positive effects on bone and cartilage and that it is suitable in the prevention and treatment of osteoporosis.
