Yamamoto Research Calcium is a food supplement with Vitamin D and Calcium. Calcium is necessary for the maintenance of normal bones and teeth and contributes to normal energy-yielding metabolism. Vitamin D contributes to the normal function of the immune system and to the normal absorption/utilisation of calcium. Vitamin D and Calcium contribute to normal muscle function.

Calcium is the mineral present in the greatest quantity in our body, about 1.8% of the total weight. 99% of calcium is found in bones and dentin, which is the substance of which teeth are made. Bones not only contain calcium but also perform a very important storage function. Calcium is mainly present in bones (98%), minimally in teeth (1%) and also in body fluids (1%). The main function of calcium in our body is linked to the construction of bones and teeth, where it plays a structural role at the level of the musculoskeletal system, but constitutes a primary source of reserve, to maintain physiological plasma concentration and ensure certain metabolic needs .

Calcium regulates muscle contraction, intervenes in the transmission of nerve impulses, keeping the nervous system healthy. Calcium then normalizes blood circulation and regulates heart rate, keeps blood pressure and cholesterol levels low, and also contributes to blood clotting. Calcium is also involved in the permeability of the cell membrane, in the multiplication and differentiation of cells, in the synthesis of some hormones and in the activation of certain enzymes. A truly multivalent role, even if it is strictly associated with the constitution of bones.

The daily calcium requirement varies from individual to individual, based on age, gender and physiological conditions. In adults 800 mg, in children (up to 10 years) 400-500 mg, in adolescents 1,000-1,300 mg, in the elderly 1,000 mg, in pregnant and breastfeeding women 1,200-1,500 mg. Calcium is essential, together with the synergistic vitamin D, for the constitution of the skeletal system already in the first months of fetal development, which is why the need increases in pregnant women and during breastfeeding. Then after the peak of skeletal maturity (between the ages of 20-30), the density of calcium in the bones begins to gradually decrease. If calcium is lacking in the first years of life, the problems mainly concern the bone structure, which has a reduced mineral density, with the risk of bone deformation and rickets. If there isn't the right amount of calcium with food, the ailments vary from the simple presence of muscle cramps (even in the abdomen) to tingling in the fingers, headaches and memory lapses, irritability and nervousness. Also dry skin, brittle nails and hair loss. To move on to real dysfunctions affecting the osteoarticular system, such as bone pain, fragility and risk of fractures, tooth decay, bone decalcification in the elderly and osteoporosis in menopausal women. Excess calcium is eliminated through body secretions: faeces, urine and sweat.
