A combination of calcium and vitamin D is one of the most scientifically-proven treatments for osteoporosis. Although you can get both in pill form, it’s crucial to combine them with a healthy diet. Some people will even argue that a pill is not enough – that a combination of calcium and vitamin D is more efficient. Clinical trials on vitamin D3 and calcium indicate that they may prevent your risk of developing certain conditions related to aging. One clinical trial even found that when osteoarthritis patients took both calcium and vitamin D3 their pain was reduced significantly while their inflammation was also reduced.
Calcium and vitamin D combination
Should you take calcium and vitamin D supplements together?

Calcium helps in building bones and keeps them healthy. Apart from this, the mineral enables our blood to clot, helps our muscles to contract, and our heart to beat. About ninety-nine percent of the body’s calcium deposit can be found in the teeth and bones.We lose calcium every day in some amount through our skin, hair, nail, sweat, urine, and faeces. So, it is important to maintain the daily intake of calcium in the body. The best way to increase the intake is through the food we eat. Dairy products like milk, yogurt, and cheese are high in calcium content. Apart from that, certain green vegetables, soymilk, and almonds are also rich in calcium content.
Vitamin D protects our bones and helps support our muscles. Apart from this, vitamin D is needed for the absorption of calcium in the body. In children, vitamin D is needed to build strong bones, and adults need it to keep the bones strong and healthy. The best source of Vitamin D is sunlight. When you step out in the sun, the sunlight reaches your skin and your body makes vitamin D from it. Spinach, okra, soybeans are other sources of vitamin D.What does the study say?
