The calcium provided by this product is in the form of citrate, which is considered one of the most easily absorbable calcium compounds, due in part to its great solubility compared to other calcium compounds. Vitamin D is necessary for the normal growth and development of bones in children and is present in the natural form D3 (cholecalciferol), which is the most easily absorbed. Insufficient calcium intake among young and adult women is of particular concern because achieving optimal bone density before age 30 helps maintain strong bones well into old age. Calcium contributes to reduce bone demineralization in post-menopausal women. Low bone mineral density is a risk factor for osteoporotic bone fractures. This benefit is achieved with a daily dose of at least 1200 mg in women 50 years of age or older. Calcium supplements provide a convenient way to increase calcium intake and have been shown to help slow the inevitable loss of bone mass that comes with aging. Calcium contributes to normal blood coagulation, energy metabolism, and the normal process of cell division and differentiation. It also collaborates in the normal functioning of the neurotransmission of digestive enzymes and muscles. Vitamin D is a fat-soluble vitamin that can be ingested with food or manufactured by the body as a result of sunlight hitting our skin. People with little exposure to sunlight often choose to supplement their diet with an extra supply of vitamin D. This vitamin assists in the normal absorption and utilization of calcium and phosphorus. It also contributes to the maintenance of normal blood calcium levels and is important for a healthy immune system and normal muscle function. This product is suitable for: • Older people, especially for those with a compromised intake of these nutrients. • Anyone with low exposure to sunlight. How to Use: Take 3 tablets a day with food. Do not exceed the expressly recommended daily dose. Suitable for vegetarians and vegans and free of lactose and gelatin.
