Calcium is important for optimal bone health throughout the life. Red Algae Calcium is an organic calcium derived from marine Red Algae, proven to help increase Bone Mineral Density. KALV is readily absorbed and bioavailable. Calcium is an essential nutrient that helps build and maintain healthy teeth and bones. Adequate Calcium intake may reduce the risk of osteoporosis . VITAMIN D3: Cholecalciferol, a must Vitamin to have with calcium, assists in enhancing calcium absorption from intestine and maintain adequate serum calcium levels. Vitamin D3 is the activated form of Vitamin D vital to bone formation. Without sufficient D3, bones can become thin, brittle, or misshapen. Together with Calcium, Vitamin D also helps protect older adults from Osteoporosis . VITAMIN K2 as (Menaquinone MK-7) is the active isomer of Vitamin K2, exclusively manufactured by Gnosis Bioresearch Italy. Calcium homeostasis depends on the interplay of modulator compounds of which vitamin K2, especially Menaquinone-7, hasassumed a vital and key role in last decades. It has a high bioavailability, a long plasma half-life. MK-7 helps to keep arteries clean from arterial calcification by directing calcium to bones and keeping it away from arteries. MAGNESIUM:Works in synergy with Vitamin D3 to enhance calcium absorption from intestines and facilitates bone health, flexibility and movement. Magnesium also has a role in stimulating bone-preserving hormones.
