Biomin H® is a bio-preparation made of hen eggshells. One gram of the powder contains about 370 mgof calcium, 0.6mgof phosphorus and 5mg ofmagnesium. There are also some traces of strontium, copper, zinc and fluor, which can either supplement or potentiate the effects of calcium. Contemporary experimental studies have shown multiple positive effects of Biomin H®. As the presence of somatomedine activity as well as trace amounts of growth factors were identified, the positive effect on the chondrocyte differentiation and cartilage growth can be expected. The positive effect of Biomin H® on the bone density was repeatedly proved in animal models of ovariectomized female rats. Clinical studies of postmenopausal and senile osteoporosis have shown that BiominH® reduces the pain, increasesmobility, reduces osteoresorption and increases bone density or it arrests its loss. It improves mobility and has analgesic effects also in women with osteoarthritis. Experimental animal studies have shown that calcium bioavailability from Biomin H® is similar or better to that fromcalcium carbonate. Clinical and experimental studies have shown that BiominH® has positive effects on the bone and cartilage and it is suitable in the prevention and treatment of osteoporosis.
