Infusion Coffee & Tea - Health Benefits of L-Theanine and Quercetin

What do coffee and tea have in common? You'll learn about the caffeinated and non-caffeinated varieties, the benefits of L-theanine and Quercetin, and the story behind every cup. Infusion Coffee & Tea is a neighborhood spot with a passion for all things caffeine and tea. You'll also learn about other great health benefits, like the antioxidant properties of the two beverages.


Almost 80 percent of the world's population uses coffee or tea every day, but how much caffeine is contained in them? The answers vary, but in general, both tea and coffee are high in caffeine. Depending on the amount of tea leaves and coffee beans used, the caffeine content of either beverage can range anywhere from a few to over a hundred milligrams. In addition to the caffeine found in coffee, tea can also contain different levels of natural substances, such as sugar.

Coffee and tea contain caffeine, a natural stimulant found in over 60 different plant species. Although it is widely consumed and safe, the content of caffeine varies depending on the preparation and ingredients used. In this article, we will discuss how much caffeine is in tea and coffee, and whether a certain amount is safe to consume. While caffeine is generally considered safe, it can be a potential source of health concerns for some people.

While the caffeine found in tea is not illegal to consume, it can cause small side effects in large doses. If you are concerned about the caffeine content of tea, speak with a medical professional. Caffeine is found in coffee beans, tea leaves, cocoa, Yerba Mate, and many other plants. Caffeine in coffee & tea is a natural stimulant and may cause a variety of side effects, so be aware of your daily limits.


Drinking L-theanine in coffee and tea has a number of benefits. The amino acid is absorbed through the intestines and circulates in the bloodstream, subsequently crossing the blood-brain barrier. It is similar to the amino acids glutamine and l-glutamine and has a similar effect on caffeine. This article discusses the health benefits and safety concerns associated with L-theanine in coffee and tea.

Although it is not abundant in food sources, L-theanine is found in various types of tea and coffee. Most teas contain the compound, with green tea containing the most. However, some other types of tea have high levels of theanine as well. Whether to drink green tea or black tea depends on your personal preference. Several studies have shown that consuming tea with l-theanine has a number of health benefits.

A recent study in the Journal of Clinical Psychiatry showed that people who consumed l-theanine in coffee and tea exhibited decreased levels of stress and anxiety. They also improved their ability to pay attention and respond to stimuli. While L-theanine is a natural supplement, you should not take too much. It can cause nervousness and jitteriness if taken in excess. Balance is the key to enjoying tea or coffee with l-theanine.

Moreover, drinking tea with l-theanine reduces the levels of "excitatory" brain chemicals that are linked to depression and stress. Studies also show that it can protect brain cells from age-related damage. Research also shows that it can trigger the release of alpha brain waves, which are associated with "wakeful relaxation" or REM sleep. Theanine helps induce the release of these waves, thereby improving relaxation, focus, and creativity.


The antioxidant quercetin is a powerful antioxidant found in both tea and coffee, and can also be purchased as a dietary supplement. The antioxidant properties of quercetin are linked to a number of health benefits, including reduced blood pressure, cholesterol, and inflammation. Free radicals are unstable molecules that can do more than just damage cells. High levels of free radicals can trigger the expression of genes that promote inflammation. High levels of inflammation are associated with heart disease and certain cancers. Quercetin is thought to decrease inflammation and may also help improve the performance of athletics.

Researchers found quercetin to be anti-inflammatory, and it significantly reduced the formation of 8-OHdG, a biomarker of DNA damage. It also reduced protein carbonyls, which are a marker of amino acid oxidation. Further, quercetin was found to reduce lipid peroxide, a substance produced by the reaction of reactive oxygen and nitrogen species to fatty acids and proteins. This antioxidant property made quercetin an important addition to the diet, and its consumption has been linked to reduced risk of Parkinson's and Alzheimer's disease.

Free radicals cause damage to cells in the body, which can eventually lead to cancer. Antioxidants fight free radicals, which steal electrons from healthy cells and make them more susceptible to cancer. While quercetin isn't a cure-all for cancer, it can be a beneficial addition to a balanced diet. Just be sure to talk to your doctor before taking any supplements. Remember, quercetin may interact with other medications and exacerbate existing conditions.

Energy boost

There are several different ways to get an energy boost, and a cup of tea or coffee can be an effective choice. However, it's important to know that the two beverages don't offer the same effects. In addition to their various caffeine contents, tea and coffee also differ in flavor. While tea is milder than coffee, the latter offers a more sustained energy boost. And besides tea being better for you than coffee, there are a few other benefits to consuming either of these beverages.

For example, tea has a higher caffeine content than coffee, so its effects are more gradual. But, if you don't like coffee or tea, you can switch to green tea to get a steady energy boost. Regardless of whether you choose green tea or black tea, caffeine is an energy enhancer, and both should be consumed in moderation. And as with anything, a cup of tea is better for your health than a cup of coffee.

While green tea contains less caffeine than coffee, it provides unique benefits. L-theanine, a natural amino acid, helps your body process caffeine more effectively, resulting in a longer-lasting boost. Also, unlike coffee, green tea won't cause jitters or withdrawal symptoms. This means you can drink coffee and tea without worry about depriving yourself of these beverages. You can enjoy a cup of tea without feeling jittery, anxious, or groggy.

Health benefits

Studies show that drinking coffee may lower your risk of developing Parkinson's disease. Caffeine from coffee helps protect the brain from damage caused by free radicals, which can lead to degeneration of cells. Some studies even suggest that coffee may reduce the risk of developing certain types of cancer. Additionally, caffeine in coffee and tea may reduce the risk of developing type 2 diabetes and help the body produce insulin more efficiently. It may also reduce the risk of cardiovascular disease, according to a review published in 2013.

While researchers have yet to establish a definitive link between caffeine and health, both beverages can boost your energy levels. However, excessive consumption may reduce your concentration and cause panic attacks. Hence, it is best to stick to tea. Depending on your taste, you can opt for either beverage. But, keep in mind that a cup of tea or coffee contains about the same amount of caffeine. In addition, consuming more than 300 milligrams of caffeine per day may cause your blood pressure to rise too high.

Both tea and coffee contain polyphenols. These polyphenols have anti-inflammatory properties. Some studies have linked tea with lower rates of cardiovascular disease, cancer, and arthritis. In addition, both beverages contain powerful antioxidants known as catechins, which can help protect the brain and reduce the risk of certain diseases. Coffee is also considered a good source of energy, but too much caffeine can lead to dependence. Tea, on the other hand, contains L-theanine, a substance found in tea that has calming properties.

Ways to prepare

When brewing your favorite beverage, there are several ways to prepare it. The first method, known as cold brew, requires no heating. Instead, cold brew relies on time to extract the best flavor from your tea leaves. To prepare this tea, you need to infuse your device in cold water for six to twelve hours. Once the steeping time is up, pour the hot tea over ice. Be sure to add a bit of sugar if you want to add it to your tea.
