The Importance of Calcium for Kidney Health

Kidney stones are a common problem that affects millions of people worldwide. One of the main causes of kidney stones is a lack of calcium in the body. Contrary to popular belief, increasing calcium intake can actually help prevent kidney stones. Calcium binds with oxalate in the digestive tract, preventing it from being absorbed into the bloodstream and potentially forming kidney stones.

Choosing the Right Calcium Supplement

When it comes to choosing a calcium supplement for kidney stone prevention, it’s important to select the right type of calcium. Calcium citrate is the preferred form of calcium for those with a history of kidney stones, as it is absorbed more easily than other forms of calcium.

The Recommended Daily Dose of Calcium

The recommended daily dose of calcium for adults is 1,000-1,200 mg per day. However, it’s important to speak with a healthcare professional before starting any new supplement regimen, as the appropriate dose may vary based on individual health needs and medical history.

Other Ways to Prevent Kidney Stones

While calcium supplements can be helpful in preventing kidney stones, there are other steps you can take to reduce your risk. Drinking plenty of water, limiting sodium intake, and avoiding high-oxalate foods such as spinach, beets, and almonds can all help prevent kidney stones from forming.

The Risks of Over-Supplementation

While calcium supplements can be helpful, it’s important to avoid over-supplementation. Too much calcium can lead to a buildup of calcium in the body, potentially causing kidney problems and other health issues. It’s important to follow the recommended dosage guidelines for calcium supplements and speak with a healthcare professional if you have any concerns.


Kidney stones can be a painful and uncomfortable condition, but there are steps you can take to prevent them from forming. Calcium supplements can be a helpful tool in preventing kidney stones, but it’s important to choose the right type of calcium and follow dosage guidelines. As always, speak with a healthcare professional if you have any concerns about your kidney health.
