Pure Encapsulations offers calcium supplements in easy-to-swallow pill form, which is why Amy Lee, M.D., certified by the American Board of Internal Medicine, a member of the National Board of Physician Nutrition Specialists and the American Board of Obesity Medicine, and head of nutrition for Nucific, is a fan of them.

These capsules are made with calcium citrate, which is more easily absorbed than some other forms of calcium and doesn’t require food to take.

Pure Encapsulations’ capsules only contain calcium, ascorbyl palmitate (a fat-soluble form of vitamin C), cellulose (a binding agent), and water.

With 90 servings per container, the $31 bottle will last you about three months. The capsules are also gluten-free, non-GMO, hypoallergenic, and NSF-certified.

Users say that the capsules are a manageable size and good quality. Several also report that they don’t have an upset stomach after taking them.
