What Are Vitamins D And K

Vitamin D and vitamin K are essential, fat-soluble nutrients.

They are generally most abundant in high-fat foods, and their absorption into the bloodstream is enhanced when they are consumed with fat.

Often called the sunshine vitamin, vitamin D is abundant in fatty fish and fish oil, but its also produced by your skin when its exposed to sunlight.

One of vitamin Ds primary functions is to promote calcium absorption and maintain adequate calcium levels in your blood. A vitamin D deficiency may cause bone loss.

Vitamin K is found in leafy greens, fermented legumes and vegetables, as well as in some fatty, animal-sourced foods, such as egg yolk, liver and cheese.

Its necessary for blood clotting and promotes the accumulation of calcium in your bones and teeth.


Vitamins D and K are fat-soluble nutrients that play an essential role in your bodys calcium metabolism.

Possible Interactions With: Calcium

If you are currently being treated with any of the following medications, you should not use calcium supplements without first talking to your doctor.

Alendronate — Calcium may interfere with the absorption of alendronate, a medication used to treat osteoporosis. Calcium-containing products should be taken at least 2 hours before or after alendronate.

Antacids that contain aluminum — When calcium citrate is taken with aluminum-containing antacids, the amount of aluminum absorbed into the blood may be increased significantly. This is a particular problem for people with kidney disease, for whom the aluminum levels may become toxic.

Blood pressure medications — Taking calcium with a beta-blocker may interfere with blood levels of both the calcium and the beta-blocker. Study results are conflicting, however. Similarly, it has been reported that calcium interferes with calcium channel blockers , but these study results are also controversial. If you take a beta-blocker or calcium-channel blocker, do not take calcium supplements without your doctorâs supervision.

Cholesterol-lowering medications — A class of medications known as bile acid sequestrants , used to treat high cholesterol, may interfere with normal calcium absorption and increase the loss of calcium in the urine. Supplementation, therefore, with calcium and vitamin D may be recommended by your health care provider.

Diuretics — Different types of diuretics interact with calcium in opposite ways.
