Tenzo’s matcha green tea will provide you with 36mg of caffeine per serving. 72mg of caffeine for every 1 level teaspoon of powder that you use. Matcha is perfect if you are looking for an extended 4-6 hour energy boost to focus and be productive. There are no jitters, spikes or headaches like you might have experienced previously with coffee. And the best part is, if you’re looking for a larger energy boost, all you have to do is use more Matcha!
When I was conducting research into South Africa’s native herbs, I was served rooibos everywhere I went. Red in the cup, fragrant to the nose and pleasing to the palate, rooibos soon became a favorite. In every meeting, I looked forward to that red tea, which is one of the only native herbs of South Africa to achieve significant commercial status. My wife and I keep it in the tea cupboard at home, and we often turn to rooibos when we want a cup of tea without caffeine.
One study that was published in the February 2010 issue of the Journal of Agricultural and Food Chemistry investigated the effects of catechins on eye diseases and found that consuming more catechins may help protect the eyes from oxidative damage and vision loss. Scientists involved in the study found evidence that catechins can pass from the digestive tract of rodents to the tissues of their eyes and reduce oxidative stress for up to 20 hours after ingestion.

Experts emphasize that the primary thrust of scientific research has been on the pure tea products -- green, black, or oolong tea, derived from a plant called Camellia sinensis. All of the many other "herbal" or "medicinal" teas found in supermarkets and health food stores may be tasty, and may be good, bad, or indifferent for your health -- but they haven't been the focus of concentrated research, says John Weisburger, PhD, of the American Health Foundation.
If not taken with sugar, the alkaline nature of green tea helps reduce the blood glucose level. Moreover, the antioxidant and astringent qualities of green tea ensure good health and better functioning of the pancreas. Improving the function of the pancreas means a more efficient and regulated secretion of insulin and the subsequent improvement in decomposing and absorbing of sugar. This increase in effective functions can help prevent the onset of diabetes.
"Tea is a good source of compounds known as catechins and epicatechins, which are thought to be responsible for tea's beneficial health effects," says Dr. Howard Sesso, associate professor of medicine at Harvard Medical School and associate epidemiologist at Brigham and Women's Hospital. These compounds belong to a group of plant chemicals called flavonoids. Research suggests that flavonoids help quell inflammation, and that in turn may reduce plaque buildup inside arteries. Green tea has slightly higher amounts of these chemicals than black tea. Both black and green teas also contain modest amounts of caffeine, ranging from about 20 to 45 milligrams per 8-ounce cup. That's roughly half the amount of caffeine in the same amount of coffee.
The rich antioxidants present in matcha tea help in cancer prevention, improved mental alertness and clarity, detoxification, free radical scavenging activity, and stronger immune defense. Polyphenols and catechin-rich matcha promotes relaxation and contributes beneficially to prevention and treatment of various medical conditions. These include bacterial, fungal, and viral infections, cancer, and type-2 diabetes. Matcha tea also assists in maintaining cardiovascular health, gastrointestinal health, and works as a superb energy booster.
Being a green tea, matcha does contain caffeine and in higher levels than other green teas. Because the entire leaf is used, matcha tea can contain nearly as much caffeine as a cup of coffee. However, caffeine release is believed to be slower because you are drinking the entire leaf. This slower release of caffeine reduces “caffeine jitters” that coffee or other teas can cause.
Our green tea is passed through a steaming treatment before rolling. Steaming applies light heat to the leaves to help halt the oxidation process before the leaves are rolled into shape. Steaming also helps expose the fresh, grassy flavor of the leaf. Green tea leaves are not allowed to oxidize after rolling, which is why they remain light color and flavor.
If you’re not sure if matcha will become a daily ritual, editor at large Christine Muhlke recommends buying a tin within the $14 to $18 range (save the under $10 matcha for baking and the over $30 for when you’re ready to commit). Some of Muhlke’s favorite brands are Chalait, Panatea, Matchaful, Kettl, and CAP Beauty, and Ippodo (seasonal releases are available at their Manhattan storefront on East 39th Street).
Rooibos tea is the best herbal tea in the world. I am an avid coffee and black tea drinker who has to give up the caffeine. I have never been an herbal tea fan so my search began for something that would satisfy my taste buds.This is it. Rooibos tea is flavorful, dark in color and is quite satisfying. It has substance and body, unlike most herbal teas I have tried. I went through the process of slowly reducing my caffeine intake over a period of 10 days so as not to suffer from withdrawals. I now am completely off the caffeine and enjoy brewing Rooibos tea in my coffee maker ( which I thoroughly cleansed with a water and vinegar solution.) I like the My Red Tea brand because it is a family oriented and socially conscious brand; 10% of their profits support education in our Rooibos farming communities. They made their first donation to a school for farm-workers in September 2016. They strive to use packaging and processes that have the least impact on the environment. They are very careful to pick suppliers who support their values and care just as much about our world and its inhabitants as they do.
Rooibos is especially rich in the super-antioxidant compound quercetin. A titan among the antioxidants, quercetin imparts benefits to the heart, helps to reduce the risk of various types of cancers, fights viruses and is significantly anti-inflammatory. Inflammation is part of all known chronic degenerative diseases. The anti-inflammatory activity of quercetin means that it helps to reduce the risk of many types of health disorders.
The next morning, I had a bagel and one daily tea, as instructed. I felt my stomach become uneasy as most stomachs do when they’re working their “digestive magic.” Suddenly, the worst cramp of my life hit me out of nowhere. It was the sharpest PANG I’ve ever felt as it made its way from my stomach to my chest. As a reflex, I jumped up. That’s when I felt another wave of pain and swiftly made my way to the restroom.
Observational studies found a minor correlation between daily consumption of green tea and a 5% lower risk of death from cardiovascular disease. In a 2015 meta-analysis of such observational studies, an increase in one cup of green tea per day was correlated with slightly lower risk of death from cardiovascular causes. Green tea consumption may be correlated with a reduced risk of stroke. Meta-analyses of randomized controlled trials found that green tea consumption for 3–6 months may produce small reductions (about 2–3 mm Hg each) in systolic and diastolic blood pressures. A separate systematic review and meta-analysis of randomized controlled trials found that consumption of 5-6 cups of green tea per day was associated with a small reduction in systolic blood pressure (2 mmHg), but did not lead to a significant difference in diastolic blood pressure.
Heat or boil water, but don’t let it completely boil and become too hot, as this can destroy some of the delicate compounds found in green tea leaves. The “ideal” temperature for brewing green tea is between 160 degrees Fahrenheit to 180 degrees F (traditionally standard Chinese green teas brew at a slightly higher temperatures). Pour hot water into the teapot to steep the leaves for only about 1–3 minutes. Larger leaves need more time to steep than finer, smaller leaves. At this point you can also add any fresh herbs you plan on steeping.
Word began to spread and rooibos tea was suddenly being put up against a number of health issues to see what benefits it showers. 50 years later, the world knows all about this powerful little herb! The exact mechanism by which it soothes colic and stomach pain is unknown, but the anti-inflammatory properties of the herb are most likely responsible.
Red tea is also known as Black tea in Asia. White, green, oolong, and black teas all come from the same plant, the Camellia sinensis. The difference in their flavor lays on the drying processes of their leaves, which determine how oxidized the final product is. Red tea is made of completely oxidized tea leaves, resulting in a darker and aromatic tea drink.
Today, an estimated 2.5 million tons of tea leaves are produced each year throughout the world, with 20 percent of that being green tea. Green tea didn’t become popular or widely distributed outside of Asia until about the early 1900s. China, other countries in Asia, countries in North Africa, the United States and Europe currently consume the most green tea worldwide.
Since green tea is less oxidized than its black tea cousin, it is technically fresher and more delicate, so it should be consumed more quickly for maximum flavor. Green tea is best consumed within six months to a year of purchase. You should also take care to store your green tea in a cool, dark place, away from light, oxygen, moisture and fragrant pantry companions like coffee or spices.
Certain studies indicate that intake of flavan-3-ols and/or anthocyanidins found in green tea may improve glycemic control and help normalize blood sugar levels. Due to its anti-inflammatory properties, green tea is believed to be beneficial for those who are at-risk or diagnosed with type 2 diabetes. Green tea’s catechins, especially EGCG, appear to have anti-obesity and antidiabetic effects.
ODS seeks to strengthen knowledge and understanding of dietary supplements by evaluating scientific information, supporting research, sharing research results, and educating the public. Its resources include publications (such as Dietary Supplements: What You Need to Know), fact sheets on a variety of specific supplement ingredients and products (such as vitamin D and multivitamin/mineral supplements), and the PubMed Dietary Supplement Subset
The risks associated with green tea are the same as those associated with any other kind of tea (common black tea, White Tea etc.) and are primarily due to the content of caffeine and tannin. The contraindications may vary with the percentage of caffeine and tannins in it. Most people might be familiar with these adversities, but it is still important to review and summarize the components responsible, as well as the associated risks.
Unsweetened brewed green tea is a zero calorie beverage. The caffeine contained in a cup of tea can vary according to the length of infusing time and the amount of tea infused. In general, green tea contains a relatively small amount of caffeine (approximately 20-45 milligrams per 8 ounce cup), compared with black tea, which contains about 50 milligrams and coffee with 95 milligrams per cup.
