Zest Tea for energy junkies

The energy boost of Zest Tea is unbeatable. This is the most highly caffeinated tea on the market, after all. And it's not just available as tea bags and loose leaf tea. Enjoy clean, high-caffeine, focus-enhancing tea, iced and in a ready-to-drink can.


Ready-to-drink energy tea, made entirely with plant-based ingredients for a cleaner, healthier way to fuel your caffeine addiction.


Standard tea has about half the amount of caffeine as coffee… but not Zest. Our energy teas contain 3x the caffeine of standard tea, up to 150mg per tantalizing cup.


You can boost energy levels, but without focus you’re shooting in the dark. Zest Tea is a natural source of L-Theanine, for enhanced focus and alertness. Channel your energy efficiently.


When you cut away all the crap poured into energy drinks, you’re left with a lighter, smoother and healthier way to boost your energy. Tea, natural flavors, vitamins and water. Delicious.


Who said drinking tea was just for grandma? From our Sweet Chai Infusion to crisp Cucumber Melon, each flavor provides you with Zest’s own unique energy boost. Explore our 6 best-selling flavors.


Green tea leaves are known for being healthy, calming and totally zen. So how can they provide the energy levels you need from your everyday tea? Here’s how we make our green and black tea - available in teabags, loose leaf teas, and iced teas - so high in energy.


Standard green and black tea contain 20-50mg of caffeine per serving. We use tea extract to naturally boost that up to 120-150mg of caffeine, for an energy boost that rivals coffee.


This simple amino acid found in loose tea leaves regulates caffeine for a smoother energy boost and extra calm focus. A recipe for enhanced productivity.


If it doesn’t taste great, what’s the point? Drinking your morning Zest is no chore, with natural fruits, spices and herbs flavoring our best blends.


Tea has numerous health benefits besides energy boosting properties. Why would you ruin that by adding a bucket load of sugar? No, that’s just not our style. At Zest, all the energy teas in our tea shop are low to no sugar.


No GMO ingredients in sight, from our hot teas to our iced cans. We keep our ingredients simple and down-to-Earth for the best flavors.


With naturally sweet ingredients and a touch of stevia leaf extract, we can please even the sweetest tooth without giving you a sugar crash.


All our teas are vegan, but if you’re looking for an energizing beverage for your keto or paleo diet, check out our zero-cal ready-to-drink range.


While caffeine provides energy, it’s the amino acid L-Theanine that provides focus. This amino acid is found naturally in tea leaves and is not present in coffee. The synergistic effect of caffeine and L-Theanine together is why tea is a great tool for boosting both energy and focus simultaneously! It can stimulate your brain by: • Increasing levels of GABA, serotonin, and dopamine for a calm and alert state of mind, • Enhancing alpha brain waves to improve creativity and attentiveness, • Slowing the onset of caffeine so your energy boost is prolonged and smooth.
After the first sip, I was hooked! It is my morning goto and gives me the perfect amount of energy. Not to mention they have amazing customer service (which I really value in a company)

I was seeking a coffee alternative for health reasons that would wake me up so I could begin my day with reading before work. The ritual of brewing a cup of tea and opening a book is my favorite way to start the day.

I was introduced to the Blue Lady black tea through my sipsby box and absolutely LOVED it! I HAD to order more! I haven't been able to drink coffee and Zest Tea was the replacement I didn't know I needed!

Which tea gives the most energy?
Zest Black Tea provides up to 150mg of caffeine per serving, so it contains more caffeine than standard black tea. We achieve this by using additional tea extract for a plant-powered energizing effect.
What tea is good for focus and concentration?
Most energizing tea types made from the Camellia sinensis plant provide L-Theanine, which is great for focus and concentration. For a herbal tea that's good for focus, try peppermint tea. The menthol in peppermint tea can help you tackle demanding cognitive tasks and keep fatigue at bay.
What is a good tea to wake you up?
Coffee may be a popular choice for a morning energy boost, but tea is far better. A smooth, comforting black tea is a great choice for the morning, as drinking green tea or any astringent tea type on an empty stomach can cause some nausea.
What tea is good for brain function?
Caffeinated tea made from the tea plant is a great source of antioxidants and amino acids, including L-Theanine which is great for brain function. Consuming a balanced diet with plenty of vitamins and minerals is also important, so you could also try tea blends that contain a range of natural ingredients. Superberry Samba, for example, contains both tea leaves and fruits.
What tea is good for sleep?
Herbal teas with a calming effect are great for sleep. L-Theanine also improves sleep, however it's best to avoid consuming more caffeine before bed. Stick to a soothing tea with less caffeine, like green tea, or a herbal tea with no caffeine, like chamomile tea.
Does tea give you more energy than coffee?
Coffee provides a lot of caffeine, there's approximately 96mg in a standard cup of coffee. Similarly, many energy drinks also contain caffeine and sugar to boost your energy levels. Tea, however, contains both caffeine and L-Theanine to create a unique energy boost. If you replace your coffee with a Zest hot beverage, you can boost your energy consumption up to 150mg of caffeine per day.
Does ginger tea give you energy?
Although ginger makes for a delicious tea, it's not one of the caffeinated drinks that provides energy. Like other herbal teas, it contains natural antioxidants and health benefits that may have a positive impact on your immune health. Ginger tea is known for a fiery, earthy flavor but having a bold flavor doesn't equate to an energy boost!
Does herbal tea contain caffeine?
If you need a caffeine hit, try drinking black tea or one of our best teas for energy. The majority of herbal infusions are caffeine-free tea, like chamomile tea or peppermint tea. They also come with a range of health benefits that are different to traditional, caffeinated tea. However, not all teas that are herbal are caffeine-free. There are exceptions to the rule! Read about yerba mate below.
How does tea create energy?
Tea is made from infusing plant leaves into water - more specifically, traditional tea is made by infusing the leaves of the Camellia sinensis plant in hot water. The plant naturally produces caffeine in its leaves, so infusing them into a cup results in a caffeinated beverage. The amount of caffeine in your cup depends on how the plant was grown and its variety, as well as how you steep the leaves. Regardless, you can safely assume that more caffeine equals more energy for your day. With the exception of Zest Tea (more on that below) most teas do not contain as much caffeine as coffee. We've even written a list of every tea type with their average caffeine content to demonstrate this.
Which tea types provide energy?
Any tea that's made from the leaves of the tea plant (Camellia sinensis) will contain caffeine. This includes:
  • Green tea,
  • Oolong tea,
  • Black tea,
  • Matcha tea (powdered fine green tea),
  • White tea,
  • Pu-erh tea.
Other caffeinated teas include yerba mate tea. The caffeine content varies between teas, for example there's a lot more caffeine in a cup of prepared matcha green tea compared to other green teas.
What are the health benefits of tea?
The best tea doesn't just provide an energy boost! Traditional tea comes with a range of health benefits, depending on the type of tea. For example, black tea may contain flavonoids that have anti-inflammatory properties for the central nervous system.
Is yerba mate tea caffeinated?
Yerba mate is a South American tea that you may have heard of before in the context of energy tea. The Argentinian yerba mate tree, which grows in South America, can be made into a grassy, slightly bitter tea that provides a source of caffeine. In an eight ounce serving of yerba mate, there's 30mg to 70mg of caffeine, depending on the brewing method. This is more than standard tea but less than Zest Tea. Of course, as yerba mate isn't made from the leaves of the Camellia sinensis plant, it doesn't provide any L-Theanine.
