How much calcium is in a typical beer?
Some beers, particularly those brewed with wheat or rye, may contain small amounts of calcium. However, the exact amount can vary greatly depending on the brewing process and ingredients used [1]. On average, a 12-ounce serving of beer typically contains between 5-10 milligrams of calcium [2].
For comparison, the daily recommended intake of calcium is around 1,000 milligrams for adults. So, you would need to drink multiple beers to exceed this amount. However, frequent beer consumption can affect calcium metabolism, potentially leading to an increased excretion of calcium in urine [1].
Which beers are the richest in calcium?
Wheat beers and Belgian-style ales tend to have higher calcium content due to the use of wheat and spelt grains, which are rich in calcium and other minerals [3]. Some specific beers, like Samuel Adams Cherry Wheat or Unibroue Eau Benite (a Quebecois wheat beer), have been reported to contain around 30-50 milligrams of calcium per serving [4].
Keep in mind that while beer can contribute to your daily calcium intake, it is still not a significant source. If you are concerned about getting enough calcium, consider exploring other food sources, such as dairy products, leafy greens, or fortified plant-based milk alternatives.
Does calcium in beer affect beer enthusiasts with dietary restrictions?
People with dairy allergies or intolerances, such as lactose intolerance, may not need to be concerned about beer's calcium content. However, those with severe sensitivities or conditions like osteoporosis should consult their healthcare providers for personalized advice on managing calcium intake from all sources, including beer.
