Matcha typically has more caffeine content than green tea, similar caffeine to black tea, and less caffeine than brewed coffee. Because matcha is produced from shade-grown tea bushes, the tea leaves tend to retain more of their caffeine content. In addition, since you’re consuming the ground tea leaf when sipping matcha, you’re ingesting more caffeine content than you would from the extraction of steeped green or black tea leaves. Like all drinks cultivated from caffeinated plants, however, a specific level of caffeine per cup of matcha tea will depend on the how the matcha was processed and prepared. Be sure and read the packaging carefully or ask your tea supplier directly for the caffeine information specific to the matcha you are buying.
Both nutritionists we spoke to agree that drinking tea when you wake up and before bed can help your system rev up and calm down, depending on which variety you choose. If you’re a tea fanatic, work in a few cups throughout the day: Unless you’re sensitive to caffeine, you can probably handle five to seven cups a day without any negative side effects, says Lagano.
Drinking green tea and matcha are considered healthy and safe, but people sensitive to caffeine should be aware that both contain decent amounts of the stimulant. In 2016, the World Health Organization also linked the consumption of hot drinks, like coffee and tea, to a higher risk of cancer of the esophagus. However, the risk is much lower than the risk of cancer from other causes, like smoking.
A juniper berry is not a true berry, but is a seed cone with unusually fleshy and merged scales that give it a berry-like appearance. Used as a spice in European cuisine, juniper berry has been used in traditional herbal medicine to support kidney and urinary tract function, as well as to help maintain healthy blood pressure levels that are already within the normal range. The essential oil can be stimulating to the kidneys. The warming and bitter properties support digestion and can soothe intestinal gas. Juniper berry can also be warming for the joints.
Ceremonial grade: Ceremonial grade is the highest quality matcha from the most carefully cultivated buds and leaves. Ceremonial grade is given the most attention to detail during processing to yield the freshest, most delicate tasting, and smoothest ground matcha. Ceremonial grade is meant to be enjoyed on its own, with no other sweeteners or additives, to really enjoy and appreciate the intended flavor.

Does green tea really burn fat, and will drinking green tea help you lose more weight? According to some research findings, consuming antioxidants found in green tea, especially catechins and the compound called EGCG, may promote metabolic health and modestly prevent weight gain. When 11 studies and articles were included in one 2009 meta-analysis that was published in the International Journal of Obesity, researchers found that “catechins or an epigallocatechin gallate (EGCG)-caffeine mixture have a small positive effect on weight loss and weight maintenance.” (12)


A University of Miami study found that even a mild dose of green tea’s antimicrobial and antioxidant compounds erased almost two-thirds of pimples from people with mild to moderate acne when used twice daily for six weeks. To benefit, make a cup of green tea, let cool, and use as a face wash, or lay the tea bag directly on the skin to act as a compress for particularly bad pimples. For oily skin, mix peppermint tea with the green tea for an oil-blasting wash. Check out more teas that also work as acne home remedies.
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.

Other Risks: Long-term consumption, in excessive quantities, may give rise to problems such as insomnia, restlessness, annoyance, irritability, headaches, hypertension, abnormal heartbeat, loss of appetite, spasms, constipation, and acute addiction to caffeine. Many times, people who are addicted to caffeine do not feel normal without the substance and suffer from acute constipation, irritation, and lack of concentration in the absence of green tea.
Already nearly calorie free, matcha is a great addition to a weight loss program by tackling the problem from both sides. It boosts metabolism and burns fat. One recent study even suggested that matcha may help burn calories by four times. At the same time, matcha does not put any stress on the body. It doesn’t raise blood pressure or heart rate, making it a safe alternative to questionable quick fixes or pharmaceuticals ridden with side effects.
In 2009, King’s College researchers found that epicatechin may protect brain cells through mechanisms unrelated to its antioxidant ability, as epicatechin is one of the few flavonoids that can cross the blood-brain barrier. The King’s College researchers reported that somehow epicatechin protects brain cells from the negative effects of beta-amyloid plaques, although the exact mechanism of how this works is still not entirely know.

May different clinical studies have shown EGCG to help skin defend against UVA and UVB rays. And because these polyphenols can accumulate in the skin, regularly drinking green tea or taking a green tea supplement with EGCG can act as all-day supplemental protection.

What I will tell you is that there are a LOT of options for these fitness teas. I did a lot of research before purchasing one, so my best advice to you is to make yourself a list of available options (see below), determine what you hope to gain from the experience (see even further below), and then research the specific ingredients for yourself. Here’s the moral of the story: They’re all very similar, but it’s important to be aware of what you are personally putting in your own body. Disclaimer: What works for one may work differently for another — so take your research seriously.
I'm a mom of two boys and live in Larkspur, CA, but still call South Africa my home. I grew up (literally) with Rooibos Tea: a naturally caffeine free beverage that has been used by generations of South Africans for anything from a delicious anytime drink, to a soothing beverage to calm Baby's colic, to putting in the bath for dry & flaky skin. You name it, Rooibos is the cure. 
Japanese green teas have a thin, needle-like shape and a rich, dark green color. Unlike Chinese teas, most Japanese teas are produced by steaming rather than pan firing. This produces their characteristic color, and creates a sweeter, more grassy flavor. A mechanical rolling/drying process then dries the tea leaves into their final shape.[54] The liquor of steamed Japanese tea tends to be cloudy due to the higher quantity of dissolved solids.[56]
So-called "detox" teas have been popular for years, primarily among people who frequent health-food stores, or consult with alternative practitioners. These days, though, they've become big business, and a handful of celebrities are touting their weight-loss benefits on social media. In a way, detox teas have become the liquid version of waist trainers–the before and after results are often dramatic, and their celeb backing generates buzz, but you may be wondering: Do they really work, and are they safe? Before you plunk down your hard-earned money and start sipping, here are five things you should know.

It all started out at the top of the year when I ordered a very popular detox tea that I saw promoted heavily on Instagram. I’d seen this product advertised by just about every pretty face and snatched body in the industry. I read no real complaints, however, when I went to the company’s website, I did notice a few customer reviews warning new drinkers to steep their tea for less than the recommended time. Basically, the instructions said to steep for four minutes, but some suggested only steeping one to two minutes max. Ladies also warned that bad cramping was inevitable, but I thought, as a grown woman, what cramp have I not experienced by now?


Rooibos tea or red tea is an herbal beverage, with medicinal properties, that is acquired from the Aspalathus linearis bush plant found in South Africa. According to the South African Rooibos Council, rooibos is not a true tea, but an herb. The fermented tea is red in color. The health benefits of red rooibos tea are abundant. It is popular due to its great taste and unique color that comes along with health benefits.


Yup, those samurai. The samurai were cultured, fearsome warriors who ranked highly in ancient Japanese caste society. Their identity was built on Zen Buddhism, practicing the principles of discipline, ritual, and purification. The tea ceremony developed into an art form and cultural tradition as the samurai added hundreds of detailed steps in the practice. Specific instructions for how to sit and how to prepare Matcha green tea, the proper hand movements and even the proper design for a tea room were recorded in detail.
Matcha is best enjoyed as soon as possible after its production. Since matcha is a ground tea, any exposure to oxygen will immediately start to degrade the color and flavor of tea. If stored sealed in a cool, dark place it can stay fresh for several weeks and up to a few months (unlike dried tea leaves which can last for up to a year or two). To ensure you’re getting a fresh matcha worth sipping, buy it from a reputable company that can tell you when and how the tea was processed and packaged. Ask your tea purveyor for directions on how to brew the best cup of that particular variety of matcha.

It’s important to note that I was not interested in, hoping for, or expecting any drastic changes to my appearance. I already lead a pretty healthy lifestyle: I drink 80 oz. of water a day, I work out at least 4-5 days a week, and I do my best to eat lean protein and lots of fruits and veggies. Like I said, I love food, but I’m usually good at keeping my cravings in moderation. I did not have a “goal weight,” and there were no numbers I was hoping to change (blood pressure, weight, heart rate, etc.). I cannot stress this enough: Acknowledge your own body, its needs, and its goals before you try any new regimen. A detox should fit into your life — you should not expect it to change your body overnight.
Along with caffeine, which gives green tea its characteristic taste, bitterness, and stimulating effect, green tea is also rich in a group of chemicals, called catechin polyphenols (commonly known as tannins, which contribute to bitter taste and astringency). These catechin polyphenols include catechin, epicatechin, epicatechin gallate (ECG), epigallocatechin gallate (EGCG), and various proanthocyanidins. They are also known as flavonoids and are very powerful antioxidants. Flavonoids, together with some amino acids like thiamine, are responsible for the potent flavor of green tea.
In 2004, scientists at the University of Newcastle studied the effects of black and green tea on Alzheimer’s disease. In laboratory studies, both teas prevented the breakdown of acetylcholine, the neurotransmitter strongly linked with memory. The teas also inhibited enzymes known as BuChE and beta-secretase. These enzymes are found in protein deposits found in the brain of Alzheimer’s patients. (7)
In January 2015, we wrote about the rapid rise of matcha on the American beverage landscape and posed the question, “Have we reached maximum matcha saturation?” Three years later, we're living amid matcha croissants, matcha custard pie, matcha face masks, matcha lifestyle guides and $50 cups of matcha itself. Clearly, the answer was "No." But what is this powder we're whisking into green lattes, baking into doughnuts, blending into smoothies, and adding to our fish fillets?
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.
Green tea is claimed to have been popularized in Japan around 1190, when a Zen priest visiting and studying in China’s great Buddhist monasteries and temples returned to Japan with tea plant seeds and bushes. The young priest, called Eisai, used his experience growing and drinking tea in China to popularize the way of tea as a meditation ritual within his own community of Buddhist monks, eventually spreading the custom of tea drinking throughout the rest of Japan. To this day, China and Japan are the top two green tea producing and exporting countries in the world.
Basically, tea time may not be for you. I know we all want “quick results,” but instead a gradual change in diet is best. Since my last tea scare, I’ve actually gotten accustomed to simply eating better. Stuff like eliminating dairy has helped with my “fupa” (lower belly pudge), and overall bloat. Limiting my red meat intake has also helped. Leaner meats like turkey, chicken breast and egg whites have helped me keep inches off and feel more energized.

The claims of weight loss within 14 days has worked for many users. V tea T-tox 14 Day Detox Tea works by boosting the body’s metabolism and suppressing appetite. Since it doesn’t have the natural laxative of senna leaves, you will be not be rushing to the washroom frequently. So, it is completely safe to take this tea to work or school for consumption later in the day.
One detox tea brand, recently Instagrammed by Amber Rose, advises per their website that for "best results," the tea should be consumed along with plenty of water, healthy, balanced meals, and three to five workouts a week. Another, which has been Instagrammed by several celebs, including Kourtney Kardashian, Christina Milian, and Hilary Duff, states online that the tea "is recommended to be taken in conjunction with a healthy energy-controlled diet and regular exercise" and the website offers an accompanying meal plan for sale. Personally, I'd love to see a study comparing outcomes generated by a detox tea compared to a placebo, with both groups following the exact same eating plan, but I haven't found any. That makes it difficult to know whether the weight-loss results people are getting from these teas are actually due to drinking them, or simply the result of' a cleaned-up diet and consistent workout routine, which we already know can lead to weight loss. In any case, simply sipping detox tea while continuing to skip the gym and order takeout is unlikely to help you shrink your shape.
The polyphenols in green tea, especially EGCG, have been shown to have a particularly powerful effect in supporting skin cells and cellular DNA in the presence of UV radiation from sunlight. May different clinical studies have shown EGCG to help skin defend against UVA and UVB rays. And because these polyphenols can accumulate in the skin, regularly drinking green tea or taking a green tea supplement with EGCG can act as all-day supplemental protection.
Tea plants that are specifically grown and used to make matcha are also typically shaded for two weeks to increase chlorophyll levels before the leaves are picked, further boosting concentration of healthy compounds. Matcha green tea tends to be more expensive than buying tea leaves for steeping, but a little goes a long way. Matcha is usually available in powder form and is a good choice for adding green tea’s taste and the benefits of green tea to recipes like smoothies, baked goods or ice cream.
Research also shows that green tea lowers total cholesterol, improving the overall cholesterol profile. One population-based clinical study found that men who drink green tea are more likely to have lower total cholesterol than those who do not drink green tea. Other clinical studies that look at populations of people indicate that the antioxidant properties of green tea may help prevent atherosclerosis, particularly coronary artery disease. The benefits also seem to extend to preventing stroke, reducing high blood pressure, and inhibiting the formation of blood clots. Much of the effect may also be due to the ability of green tea to help lower blood sugar and insulin levels.
I absolutely LOVE this tea! I drink about 3-4 hot cups a day... with a touch of honey, a squeeze of fresh lemon and a sprig of fresh mint, it is absolutely the best! I've had it by itself without anything added and it's still absolutely the best! I've also noticed that when I drink it on a regular basis, my tummy feels flatter and my body and mind feel cleaner. I've yet to try it as an iced tea but, I think that I'll do that tomorrow and I'm sure that it will be as good cold as it is hot! I love the fact that I can buy it on Amazon in bulk for such a great price! I'm a Yogi Peach Detox fan and I'll be a customer for life!
Unlike traditional green tea, matcha preparation involves covering the tea plants with shade cloths before they’re harvested. This triggers the growth of leaves with better flavor and texture, which are hand selected, steamed briefly to stop fermentation, then dried and aged in cold storage, which deepens the flavor. The dried leaves are then stone-ground into a fine powder.
Another benefit of green tea it’s is lower in caffeine than most other teas, so you may be able to drink the five cups a day that lowered psychological stress in a large group of Japanese people in a recent study done at Sendai’s Tohoku University Graduate School of Medicine. The researchers didn’t identify any particular component of green tea that might have been soothing, but animal studies suggest that one compound, EGCC, had both sedative and hypnotic effects that tamp down the body’s production of stress chemicals.

In China during the Tang Dynasty (618–907), tea leaves were steamed and formed into tea bricks for storage and trade. The tea was prepared by roasting and pulverizing the tea, and decocting the resulting tea powder in hot water, then adding salt.[2] During the Song Dynasty (960–1279), the method of making powdered tea from steam-prepared dried tea leaves, and preparing the beverage by whipping the tea powder and hot water together in a bowl became popular.[3]


Green tea is considered one of the world's healthiest drinks and contains one of the highest amounts of antioxidants of any tea. Natural chemicals called polyphenols in tea are what are thought to provide its anti-inflammatory and anti-carcinogenic effects. Green tea is approximately 20-45 percent polyphenols by weight, of which 60-80 percent are catechins such as EGCG. Catechins are antioxidants that are said to help prevent cell damage.

In addition to actual tea, detox concoctions typically include additional herbs, which may be designed to curb appetite, rev metabolism, or boost weight loss in other ways. One example is senna, a plant with a natural laxative effect. According to the Natural Medicines Comprehensive Database, the potential side effects of senna use may include abdominal pain and discomfort, cramps, bloating, gas, nausea, and diarrhea; excessive use can lead to potassium depletion and other electrolyte abnormalities, which can trigger muscle spasms and an abnormal heart rhythm. Another popular ingredient in weight loss teas is guarana, a plant that's often added to energy drinks. Its side effects are commonly related to its caffeine content, which may include nervousness, restlessness, stomach irritation, nausea, vomiting, headache, anxiety, agitation, ringing in the ears, and fast heart and breathing rates. Bottom line: Do your homework about exactly what's in a product before you put it in your body. Even "all-natural" substances can have potential side effects, especially if they're overused, combined with other supplements or medications that result in negative interactions, or if taken by those with pre-existing medical conditions.
Most detox teas contain caffeine, probably because this stimulant may suppress appetite, trigger your digestive system to let go of waste, and help you shed water weight. A caffeine-induced energy boost may also lead to working out a little longer or harder than usual. However, too much caffeine can also be risky (see above) and interfere with getting enough sleep–and catching too few zzzs may ultimately undo the tea's weight-loss effects. In fact, too little shuteye has been shown to trigger excessive eating and weight gain and even slow metabolism, which can make it easier to gain weight even if you don't eat extra calories. A good rule of thumb, regardless of where your caffeine is coming from, is to nix it at least six hours before bed. And if you're trying to shed pounds, commit to making adequate sleep a top priority.
