The Mineral Content of Coffee: What You Need to Know

Coffee is a very popular drink, and for good reason, too. It contains a bunch of essential nutrients that are very good for you and can help you tremendously if you are trying to become stronger and healthier. One of the minerals that is found in coffee is calcium, and it is through calcium that coffee becomes such a powerful health drink. Calcium can be used by the body in multiple ways, some of them being more beneficial than others. Knowing what minerals are found in coffee and how you can benefit from drinking it can make your morning routine a lot easier, especially if you have to skip breakfast to make it to your 9-5 job.

What Minerals are Found in Coffee?

Coffee is a unique fruit product. In fact, it is a seed that has been processed and grown using methods that have been passed down through many generations. Coffee plants are very picky about how they process their seeds, and they will only allow the seeds to grow into a plant if the conditions are right. Many of the crops that we use to create fertilizers and pesticides for other fruits and vegetables aren’t allowed to grow in most natural environments, but because coffee is such an expensive crop to produce, the growers have been able to use these methods to create healthy crops of coffee.

There are many minerals that can be found in coffee beans, each of them with their own special qualities that you might enjoy finding out about. Here are a few of the more common minerals found in coffee beans.


Calcium is one of the most commonly found minerals in humans, as well as in many other mammals. It is important for human health thanks to the body’s ability to store reserves of it within itself. Calcium deficiency isn’t often considered a disease, but your body does need calcium in order to function properly. Children under 12 years old generally don’t need supplementation with calcium, but if you aren’t getting enough calcium from food or your diet isn’t well-balanced, then supplementation may be required.[1]

Arguably one of the most important reasons why people should consider drinking coffee is because of its high level of calcium. The recommended daily allowance (RDA) for calcium is only 1000 mg per day, and up until recently it was thought that we didn’t need further exposure to supplemental calcium than we already get through our diet. However, research has shown that even small amounts of supplemental calcium can be beneficial, [2] and I believe that everyone should be taking at least some supplemental calcium every day.


Amino acids (the building blocks of protein) are also found in abundance within coffee beans. Because of this, caffeine consumption has been associated with an increased risk for hypertension[3], though not everyone responds similarly to caffeine[4]. If you are concerned about keeping your blood pressure up during the day, then drinking black tea instead of or alongside of regular tea might be something you want to consider doing.


Iodine deficiency isn’t really considered a major problem anymore thanks to consumption from table salt (salt contains iodine). However, due to how we process salt (only allowing free flowing salt or none at all), our iodine levels aren’t as strong as they could be.[5] Iodine deficiency has been linked with goiters (swelling on thyroids), so making sure that you are getting enough iodine can potentially help increase thyroid size if you suffer from any kind of thyroid issue.

Other Minerals

There are many other minerals found in coffee beans; iron, [7], copper, [8], manganese, [9], lithium, [10] rubidium, [11] strontium, [12] niobium, [13] molybdenum[14], vanadium[15], zirconium[16], hafnium[17], tantalum[18], tungsten[19], osmium[20], iridium[21], platinum group metals[22], gold group metals23], and mercury24]. All of these minerals play an important part in human health either due to their importance within the human body or due to the disease prevention properties that they contain.
