Does Coffee Affect Calcium Absorption?

Coffee is one of the most popular beverages in the world and has been consumed for centuries. However, there is some debate about whether or not coffee affects calcium absorption. Some studies have shown that coffee may reduce calcium absorption, while other studies have found no significant effect.

The truth may depend on a number of factors, including how much coffee is consumed and what type of coffee is consumed.

Does Your Caffeine Intake Ruin Absorption of Nutrients?

Coffee is a popular morning beverage for many people, but did you know that it can actually affect calcium absorption? Studies have shown that coffee can inhibit the absorption of calcium by as much as 30%. This means that if you’re drinking coffee regularly, you may not be getting all the calcium your body needs.

What’s more, this effect is cumulative, so the more coffee you drink, the greater the impact on your calcium levels. So if you’re concerned about your bone health, it’s best to cut back on the coffee or switch to decaf.

Foods That Block Calcium Absorption

There are a few different foods that have been shown to block calcium absorption. Some of these include: phytic acid, oxalates, and phosvitin. Phytic acid is found in whole grains, beans, and nuts.

It binds to calcium and other minerals, making them unavailable for absorption. Oxalates are found in spinach, chard, beet greens, rhubarb, and cocoa. They also bind to calcium and other minerals, making them unavailable for absorption.

Phosvitin is found in egg yolks and inhibits the uptake of calcium by the gut. While these foods can block calcium absorption, it’s important to remember that they are still good for you and contain other nutrients that are essential for health. Just be sure to get enough calcium from other sources (such as dairy products or supplements) if you’re consuming any of these foods on a regular basis.

Does Coffee Affect Calcium Intake?

As any coffee lover knows, there is nothing quite like starting the day with a hot cup of joe. For many of us, coffee is an essential part of our daily routine. But what you may not realize is that your morning cup of coffee could be affecting your calcium intake.

Coffee contains caffeine, which is a diuretic. This means that it can cause you to lose more fluid through urination than you would if you didn’t drink coffee. When you lose fluid, you also lose electrolytes like calcium.

Calcium is important for many things including bone health, muscle function, and nerve transmission. So, if you’re not getting enough calcium in your diet, drinking coffee could contribute to calcium loss and lead to health problems over time. If you’re worried about how coffee affects your calcium intake, there are a few things you can do.

First, make sure to drink plenty of water throughout the day to stay hydrated. You can also get more calcium by eating foods that are rich in this mineral such as dairy products, leafy greens, and certain types of fish (sardines and salmon). And lastly, consider limiting your caffeine intake to no more than 400 mg per day (about 4 cups of coffee).

By following these tips, you can enjoy your morning cup of coffee while still getting the nutrients your body needs.

How Long After Drinking Coffee Can I Take Calcium?

It is best to wait at least 30 minutes after drinking coffee before taking calcium. This allows the caffeine time to be absorbed into your system and prevents it from interfering with the absorption of calcium.

What Interferes With Absorption of Calcium?

There are a number of things that can interfere with the absorption of calcium. For example, if you don’t have enough vitamin D in your system, your body won’t be able to absorb calcium as well. Additionally, certain medications (such as antacids and corticosteroids) can also interfere with calcium absorption.

Finally, having too much phosphorus in your diet can also inhibit calcium absorption.

What Foods to Avoid If You Have Calcium Deposits?

If you have calcium deposits, it is important to avoid foods that are high in calcium. This includes dairy products, such as milk, cheese, and yogurt. Other foods to avoid include leafy greens, such as spinach and kale, as well as nuts and seeds.

Additionally, it is important to limit your intake of salt and sugar. These foods can contribute to the formation of calcium deposits and should be avoided if you are trying to prevent or treat this condition.


A new study has found that coffee may have an effect on calcium absorption. The study, which was published in the Journal of Bone and Mineral Research, looked at how different beverages affect calcium absorption. The study found that coffee decreases calcium absorption by about 6%.

This means that if you drink two cups of coffee, you’ll absorb about 12% less calcium than if you didn’t drink any coffee. The study also found that tea had a similar effect on calcium absorption. However, the effect was not as strong as with coffee.

So what does this mean for your health? If you’re trying to get enough calcium for your bones, it’s best to limit your caffeine intake.
