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.
In a decade-long study of Japanese adults, death from all causes together, and also death from specifically heart disease and stroke, were all reduced in both women and men who drank the most green tea (5 or more cups per day) versus those who drank less than one cup per day. Another study found that those who drank the most green tea were 76% less likely to die during the 6 year study period.
• One Chinese study found that men who drank more than three cups of tea a day reduced their risk of prostate cancer by 70 percent. In another study funded by the National Institute of Health, 79 men with prostate cancer were told to either drink 6 cups of green tea a day or 6 cups of water. After 3 to 8 weeks, the levels of prostate-specific antigen, a protein that may indicate cancer, were lower in the men who drank green tea than those who drank water. An indicator of inflammation, nuclear factor-kappaB, linked to cancer growth, was also lower in the men who drank the green tea.
It is used in castella, manjū, and monaka; as a topping for shaved ice (kakigōri); mixed with milk and sugar as a drink; and mixed with salt and used to flavour tempura in a mixture known as matcha-jio. It is also used as flavouring in many Western-style chocolates, candy, and desserts, such as cakes and pastries (including Swiss rolls and cheesecake), cookies, pudding, mousse, and green tea ice cream. Matcha frozen yogurt is sold in shops and can be made at home using Greek yogurt. The Japanese snack Pocky has a matcha-flavoured version. Matcha may also be mixed into other forms of tea. For example, it is added to genmaicha to form what is called matcha-iri genmaicha (literally, roasted brown rice and green tea with added matcha).
The antioxidants present in rooibos tea slow down the aging process and also boost the strength of the immune system. Researchers at Nelson Mandela Metropolitan University in South Africa found that the local herb helps slow down the degeneration of fat cells, thus inhibiting the formation of wrinkles. Antioxidants in the tea seek out free radicals that damage the skin, hair, bones, and other organ systems by making them vulnerable to diseases and degeneration.

Most importantly, EGCg and other catechins counteract the effects of free radicals from the likes of pollution, UV rays, radiation, and chemicals, which can lead to cell and DNA damage. Since over 60% of the catechins in matcha are actually EGCg, a daily matcha regimen can help restore and preserve the body’s integral well-being and balance. Read more on our Change The Odds Page.

A study suggests that theanine found in matcha tea acts as a neurotransmitter. It exerts a calming effect on the brain without causing any drowsiness. This soothing effect helped the Buddhist monks in maintaining deep concentration during their meditation sessions and was the main reason behind its popularity. Another study has revealed the anti-stress effects of theanine present in this tea, which assists in reducing the physiological and psychological stress responses by inhibiting the neuron excitation. Matcha tea is also believed to boost memory and concentration.
The taste is of matcha is strong. Some people describe it as grass or spinach-like, and it has an umami taste. Because of this it may be sweetened to improve its palatability. One client was thrilled to tell me that he was drinking matcha, but instead of traditional matcha powder, he was drinking a powdered mix. The first ingredient was sugar, and it also contained powdered milk, so it was essentially like hot chocolate—but with cocoa swapped for matcha—something I wouldn’t recommend. Tea experts also warn that with matcha quality is key, and it comes at a cost. In other words, high quality, fresh, pure matcha is expensive. A low price tag can be a red flag for a poor quality product. I like Jade Leaf Organic Japanese Matcha Green Tea Powder ($19; amazon.com), because it's USDA certified organic, third party tested for contaminants, and from Japan.
The leaves are used to make a herbal tea that is called by the names: rooibos, bush tea (especially in Southern Africa), or redbush tea (predominantly in Great Britain). The tea has been popular in Southern Africa for generations, but is now consumed in many countries worldwide. It is sometimes spelled rooibosch in accordance with the original Dutch. The tea has a taste and color somewhat similar to hibiscus tea, or an earthy flavor like yerba mate.

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.
I really like this stuff! I"ve used green tea powder for smoothies for years and I find this brand to be effective at keeping sustained energy throughout the day. It has a very definitive taste to it, but it's easy to cover up if you don't like it. (I don't mind the taste, but my protein powder pretty much overwhelms it.) It's definitely worth trying for a more sustained, less jittery caffeine boost.
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.
Rooibos contains polyphenols that have anti-inflammatory, antiviral, and antimutagenic qualities. Polyphenols are organic chemicals that are often praised for their antioxidant capabilities. Studies suggest that regularly drinking organic red rooibos tea provides the liver with potent antioxidants, helping the organ to improve detoxification. Antioxidants act as scavengers of free radicals throughout the body, which are detrimental byproducts of cell metabolism that can cause cancer and heart diseases. Aspalathin and nothofagin are two other vital antioxidants that rooibos tea contains, making it a great beverage to boost your immune system and protect your body against all types of diseases.
Green Tea comes from Camellia sinensis leaves that are immediately steamed or pan-fired rather than being exposed to air so that no oxidation occurs.   This special handling makes for a more delicate brew that is typically lower in caffeine than black and Oolong teas.  Although amounts vary, green teas are highest in polyphenols known as EGCG, which is why so many make it part of their healthy lifestyle.
In China though, the term black tea or dark tea typically refers to a tea that we call Pu-erh in the United States. This tea is fermented anywhere between 2 weeks to two months and then aged for 2 months to 20+ years in order to create dark black leaves and a dark color to the brew. In this fermentation process the leaves are intentionally kept damp to encourage good microbes and bacteria to slowly oxidize and ferment the leaves. This is distinguished from red tea which typically only takes about 6-10 hours to oxidize. Pu-erh tea typically has a strong fermentation taste but high quality pu-erh should not taste overly earthy as this is a sign of low quality production techniques.
Sejak (세작; 細雀; lit. "thin sparrow"), or dumul-cha (두물차; lit. "second flush tea"), is made of hand-picked leaves plucked after gogu (20–21 April) but before ipha (5–6 May).[77][78][79] The tea is also called jakseol (작설; 雀舌; lit. "sparrow tongue") as the tea leaves are plucked when they are about the size of a sparrow's tongue.[78] The ideal steeping temperature for sejak tea is 60–70 °C (140–158 °F).[80]
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.
Diabetics lose their sensitivity to insulin, which means insulin is less effective in signaling to cells to absorb sugar from the blood stream, resulting in both higher blood sugar and higher blood insulin levels. Because both sugar and insulin are damaging to the cardiovascular system, over time many adverse effects result. (The more sensitive you are to insulin, and in general the lower your normal blood sugar level, the better.)
It also appears to contain more EGCG. ConsumerLab.com, an independent testing group, tested matcha products in 2015 and found that matcha provided 17 mg to 109 mg of EGCG per serving. By comparison, the average brewed green tea provides 25 to 86 mg per serving. While matcha powders contained more catechins per gram than brewed green tea, it was substantially more expensive: The lowest cost matcha powder was available at the time for $2.31 for 200mg of EGCG, compared to 27 cents for the same amount from brewed green tea. Compared to the powders, matcha in tea bags provides significantly less EGCG.
Did the detox tea drastically change my life? No. But did it reduce bloat, give me some new confidence, and taste great in the process? Yes. If you’re looking for a quick solution to lose weight, this is not for you. But if you’re looking for a delicious supplemental addition to a consistent workout regimen and a healthy diet, this IS for you. Don’t expect the tea to do all the work for you, but expect it to work with you — helping you out wherever you’re at on your journey to your healthiest self.
Rooibos is being heavily hyped by producers and distributors as a new health beverage. Unlike true “tea,” it is caffeine-free and low in tannins. It contains minimal amounts of calcium, potassium, iron, zinc, magnesium and much less fluoride than found in real teas. Studies have shown that Rooibos does contain antioxidants and therefore might have some of the health benefits of green tea, but very little research has confirmed this. I found only 17 scientific studies of Rooibos compared to more than 1,000 on green tea. So far, none suggest that Rooibos is the health equivalent of green tea.

According to a study published in the journal Chinese Medicine, many of the beneficial biological effects of flavonoids on heart health seem to be due to cell-signaling effects that lower inflammation. (6) Not only do flavonoids have anti-inflammatory capabilities, but they’re also antithrombogenic, antidiabetic, anticancer and neuroprotective compounds.

Although numerous claims have been made for the health benefits of green tea, human clinical research has not provided conclusive evidence of any effects.[2][7][11] In 2011, a panel of scientists published a report on the claims for health effects at the request of the European Commission: in general they found that the claims made for green tea were not supported by sufficient scientific evidence.[7] Although green tea may enhance mental alertness due to its caffeine content, there is only weak, inconclusive evidence that regular consumption of green tea affects the risk of cancer or cardiovascular diseases, and there is no evidence that it benefits weight loss.[2]
According to Record of Gaya cited in Memorabilia of the Three Kingdoms, the legendary queen Heo Hwang-ok, a princess of the Ayodhya married to King Suro of Gaya, brought the tea plant from India and planted it in Baegwolsan, a mountain in current Changwon.[67]:3 However, it is a widely held view that systematic planting of tea bushes began with the introduction of Chinese tea culture by the Buddhist monks around the 4th century.[68] Amongst some of the earliest Buddhist temples in Korea, Bulgapsa (founded in 384, in Yeonggwang), Bulhoesa (founded in 384, in Naju) and Hwaeomsa (founded in Gurye, in 544) claim to be the birthplace of Korean tea culture.[68] Green tea was commonly offered to Buddha, as well as to the spirits of deceased ancestors.[68] Tea culture continued to prosper during the Goryeo Dynasty, with the tea offering being a part of the biggest national ceremonies and tea towns were formed around temples.[69] Seon-Buddhist manners of ceremony prevailed.[69] During the Joseon Dynasty, however, Korean tea culture underwent secularization, along with the Korean culture itself.[69] Korean ancestral rite jesa, also referred to as charye (차례; 茶禮, "tea rite"), has its origin in darye (다례; 茶禮, "tea rite"), the practice of offering tea as simple ancestral rites by the royal family and the aristocracy in Joseon.[69]
To make green tea, the leaves are quickly steamed or heated to stop oxidation, the chemical process that causes browning. To make black tea, the leaves are crushed, torn, curled, or rolled and allowed to oxidize before being dried. This additional processing step degrades some of the flavonoids. As a result, black tea has slightly lower amounts of flavonoids than green tea.

Detox teas that combine caffeine with diuretics can trigger the loss of water weight. Just two cups of water weighs one pound on a scale, so shedding fluid can make you look and feel lighter–even if you haven't lost an ounce of body fat. Detox teas can also trigger a laxative effect, which causes your body to eliminate waste from your GI tract, another result that can make your stomach flatter, and allow you to feel lighter, even if your lean-to-fat ratio remains exactly the same. If this quick-fix effect gives you the confidence boost and motivation you need to start eating healthier and working out–the real keys to getting healthy and lean–terrific (assuming the teas are even safe to drink–see below). Just remember: If you go back to your former less-than-stellar eating or exercise habits, or stop drinking the tea, you can gain the weight right back just as quick as you dropped it.
Even organically grown green teas have been shown to contain lead, which is absorbed by the plant from the environment, particularly tea grown in China. When traditional green tea is steeped, about 90% of the lead stays in the leaf, which is discarded. With matcha, since the whole leaf is consumed, you will ingest more lead. One independent group, ConsumerLab.com, which tested teas, estimates that a cup of matcha may contain as much as 30 times more lead than a cup of green tea. Therefore, they recommend drinking no more than one cup daily, and not serving it to children.
Japanese researchers published a study on green tea and its effect on the beta-amyloid protein plaques found in Alzheimer’s disease in the April 2008 issue of the Journal of Nutritional Biochemistry. The protein plaques associated with Alzheimer’s disease increase brain cell damage and death due to oxidative stress. The researchers found that green tea catechins reduced the level of damaging free radicals in the brains of rats. The green tea rodents showed much less plaque-induced deficits in memory compared to rodents that didn’t receive green tea and those that were infused with beta-amyloid proteins. (8)
Day 1: So you’re supposed to drink your tea first thing in the morning (or before a workout), but I didn’t receive my package until after arriving home for the day (in the early evening). Since I am a slave to my own desire for instant gratification, I said “Screw the rules!” and made my first cup right then and there. Immediate observation: It’s actually pretty delicious. I don’t consider myself a tea connoisseur by any means, so I was pleasantly surprised. I didn’t think it needed the recommended addition of honey.

You can make African red tea much like other herbal teas, according to Teavana. Add a 1 1/2 teaspoons of loose African red tea to make an 8-ounce serving, using boiling water. Allow the tea to steep for roughly five to six minutes, longer if you wish for a stronger tasting tea. Letting the tea steep for longer will not cause the tea to become bitter. Indeed, traditionally, African red tea has been allowed to steep for several days. If you want to make chilled African red tea, you can place the hot tea in the fridge to let it cool. Alternatively, double the amount of tea used and then pour the hot tea over a glass filled with ice cubes.
