The Importance of Water for Calcium Absorption

Calcium is an essential mineral for the human body, as it plays a vital role in the development and maintenance of strong bones and teeth. It also aids in muscle and nerve function, as well as blood clotting. However, consuming enough calcium is not enough to ensure its proper absorption in the body. The intake of water also plays a crucial role in calcium absorption.

How Water Helps in Calcium Absorption

Water is essential for numerous functions in the body, including digestion and the transportation of nutrients. When it comes to calcium absorption, water plays a critical role in dissolving the mineral and making it available for absorption in the small intestine.

Calcium, in its natural form, is not easily absorbed by the body. It needs to be ionized, or chemically charged, in order for the body to absorb it. This process is called solvation, and it occurs when calcium is dissolved in water, converting it into its ionic form, calcium ions (Ca2+).

The calcium ions are then easily absorbed by the body through the intestinal wall and into the bloodstream. From there, they are transported to the bones, teeth, and other body tissues that need calcium for various functions.

The Significance of Hydration for Calcium Absorption

Besides aiding in solvation, staying hydrated also has other benefits that contribute to proper calcium absorption. Water helps to maintain the proper acid-alkaline balance in the body, which is essential for the absorption of minerals, including calcium.

The body needs a slightly acidic environment to absorb calcium, a crucial factor that many people tend to overlook. When the body is dehydrated, the urine becomes concentrated, leading to an increase in acidity, making it difficult for calcium to be absorbed. Therefore, proper hydration is necessary to maintain the body’s fluid balance and ensure a suitable pH level for the absorption of calcium.

How Much Water is Enough?

The amount of water needed for proper hydration varies from person to person, depending on factors such as age, gender, and physical activity. However, the general recommendation is to drink eight 8-ounce glasses of water per day, which is equal to about 2 liters or half a gallon.

It is especially crucial to drink enough water if you consume a high-calcium diet. Experts recommend that an additional 6- 8 ounces of water for every 250 mg of calcium consumed. So, if you consume a 1000mg calcium diet, you should drink at least 64 ounces or 2 liters of water per day.

Other Ways to Increase Calcium Absorption

Ensuring adequate water intake is one of the most effective ways to increase calcium absorption. However, there are other measures you can take to optimize the absorption of calcium, including:

  • Consuming calcium-rich foods in small portions throughout the day rather than one large serving.
  • Pairing calcium with foods rich in vitamin D, as it enhances calcium absorption.
  • Limiting the intake of items that can inhibit calcium absorption, such as caffeine, alcohol, and high amounts of sodium.
  • Increasing your intake of foods high in vitamin K, which can help regulate calcium levels in the body.


In conclusion, water plays a crucial role in the absorption of calcium, a vital mineral for overall health. It helps to dissolve calcium, making it available for absorption by the body. Staying hydrated also helps maintain the proper acid-alkaline balance necessary for calcium absorption. Therefore, drinking the recommended amount of water daily, along with a balanced diet, can help optimize calcium absorption and promote better health.
