Vitamin D and Inulin Aid Calcium Absorption

August 4, 2020

You’ve probably heard about the many benefits of calcium to your bones, but did you know that vitamin D and inulin also are very important? Vitamin D supports the absorption of calcium into your body and helps support muscle strength.1 Inulin, a prebiotic, can also aid your body’s absorption of its needed calcium, helping to improve the strength of your bones and mineral density.2 

Both calcium and vitamin D are needed to maintain strong bones and a strong body. Most people need 1,000 mg of calcium and 400-800 IU of vitamin D per day. That daily amount increases for those over age 50, who need 1,200 mg and 800-1,000 IU, respectively.1  Additionally, it is suggested that people include about 4 to 5 grams of prebiotics in their diet every day. Prebiotics found in fruits and vegetables like onions, asparagus, leeks, and chicory root help support digestive health as well as calcium absorption. 

With so much calcium needed every day, particularly as we age, it’s vital to replace the calcium our body loses through sweat, skin, hair, and the digestive system. If we don’t replace it, the body turns to its only source of calcium: bones and teeth.1 

As vitamin D and inulin enhance the absorption of calcium, it’s important to maintain a healthy level of these as well. Vitamin D can be absorbed through sunlight, foods such as fatty fish, and supplements. When your skin interacts with the sun, it produces vitamin D and stores it in fat cells.1 As we age, our body’s ability to do this vital process decreases. Plus, you might not be getting enough vitamin D if you spend the majority of your time indoors, or have health issues such as high BMI or celiac disease. 

Inulin can be found as an added element in foods such as breads and cereals – providing both sweetness and prebiotic fiber benefits. However, these foods can be difficult to pick out among the hundreds of options lining your local grocery’s shelves. Supplements for vitamin D, calcium, and prebiotics are a sure way to ensure you’re meeting your body’s needs. Fiber Choice® with Calcium and Vitamin D for Bone Health contains vitamin D and calcium, and prebiotic fiber from inulin. You can find Fiber Choice here.
