VITAMIN D: Vitamin D is also an essential nutrient for maintaining strong bones by helping the body absorb and use calcium and phosphorus and regulate normal levels of calcium in the blood. Calcium and vitamin D help reduce bone mineral loss in post-menopausal women. Low bone mineral density increases the risk of osteoporotic bone fractures. Calcium and Vitamin D are essential for normal bone growth and development in children. ZINC: Zinc is a trace element that is equally important in supporting our health and wellness. It cannot be stored naturally in the body so it should be taken through daily diet or supplements. It helps heal wounds and reduce inflammation, and maintain bone strength and muscle function. In addition to calcium and magnesium, it is also needed to boost the immune system. Zinc deficiency leads to a decrease in calcium absorption. Zinc helps restore normal bones, hair, nails and skin. MAGNESIUM: Magnesium is responsible for more than 300 enzyme reactions in the human body. It plays a key role in maintaining bone health, muscle function, energy levels & reducing fatigue & tiredness. Like calcium, these minerals are essential for the nerves to carry messages to the brain more efficiently. That is why Calcium & Magnesium are effective in relieving muscle pain & restless legs syndrome. Calcium & Magnesium contribute to normal muscle function & help keep bones & teeth normal. CALCIUM: Calcium is a mineral that is essential for building bones and keeping them healthy. It is necessary for our blood to clot, for the muscles to work, and for the nerves to carry signals between the brain and other parts of the body. Most of the calcium in our body is found in our bones and teeth, so when the calcium level drops, our bones are supplied, which eventually weakens and leads to a disease called osteoporosis. Calcium also helps reduce post-menopausal bone loss in women. HIGH STRENGTH: Each serving provides 100% or more of your daily needs for vitamin D3, magnesium, zinc and calcium. You get 5µg of Vitamin D, 320mg of Calcium, 150mg of Magnesium and 15mg of Zinc. The most important thing is that we have prepared it so that each ingredient helps the other, it is very clear with vitamin D which helps in absorbing calcium. Calcium, magnesium and zinc are the three most important minerals that the body needs for bone health.
