FAQ

HIGH CAFFEINE TEAS
HOW DO YOUR HIGH CAFFEINE TEAS REDUCE THE JITTERS AND CRASH?
Our high caffeine teas are packed with amino acids, including L-Theanine, which studies show helps moderate caffeine’s effects. Read more here.
HOW MUCH CAFFEINE IS IN ZEST HIGH CAFFEINE TEAS?
Our high caffeine black teas contain 150mg of natural caffeine per serving, and our high caffeine green teas contain 135mg.
IS IT REALLY THE MOST CAFFEINATED TEA ON THE MARKET?
As far as we know, yes. And by quite a margin. Zest high caffeine teas have about 3x the caffeine of normal tea, or about as much caffeine as a regular cup of joe.
CAN THE LEVEL OF CAFFEINE IN ZEST HIGH CAFFEINE TEAS BE HARMFUL?
Up to 400mg of caffeine per day is generally considered safe. With 135-150mg per serving, Zest’s high caffeine teas are comparable to a cup of coffee.
HOW DO YOU INCREASE THE CAFFEINE LEVELS?
We have developed an innovative proprietary blending method that enhances the caffeine levels. The extra caffeine comes from natural tea extracts. The process and ingredients used are natural.
THE TEA IS WHITE, IS THAT MOLD?
Tea in its natural form isn’t as caffeinated as we’d like it to be, so we developed a way to add more caffeine to our blends using natural tea extracts. A common side effect during this process is the whitening of the tea.
ENERGY DRINKS
HOW MUCH CAFFEINE IS IN A ZEST ENERGY DRINK?
150mg of caffeine per 12oz can in Passionfruit Berry and Pomegranate Mint, and 120mg in Blackberry Lime.
WHAT IS IN A ZEST ENERGY DRINK?
Sparkling water, real black and green tea, green tea extract, L-Theanine, natural flavors and B vitamins. Passionfruit Berry and Pomegranate Mint are sweetened with cane sugar. Blackberry Lime uses erythritol and stevia leaf extract and has zero sugar.
DO YOUR ENERGY DRINKS CONTAIN TEA?
Yes. Every flavor is built on real brewed tea plus green tea extract, which is where the caffeine and the L-Theanine come from. They are energy drinks made from tea, not from synthetic caffeine.
WHICH ZEST ENERGY DRINK IS SUGAR FREE?
Blackberry Lime. It is sweetened with erythritol and stevia leaf extract instead of cane sugar, and carries 120mg of caffeine.
WHY DON’T I GET THE JITTERS FROM A ZEST ENERGY DRINK?
Every can carries 100mg of L-Theanine, the amino acid found naturally in tea. Studies show L-Theanine moderates the effects of caffeine, which is why the energy comes on smooth instead of sharp.
WHAT ENERGY DRINK FLAVORS DO YOU MAKE?
Passionfruit Berry, Pomegranate Mint and Blackberry Lime, plus a 24-can variety pack.
ZEST ELITE (CREATINE + ELECTROLYTES)
HOW MUCH CREATINE IS IN ZEST ELITE?
5 grams of pure creatine monohydrate per stick — the clinically studied daily dose, with no fillers. One stick a day, no loading phase required.
DOES ZEST ELITE HAVE CAFFEINE?
No. Zest Elite has no caffeine, so it works any time of day, including evenings.
HOW MUCH WATER DO I USE PER ELITE STICK?
16 to 32 oz of cold water per stick. That is a full water bottle, not an 8 oz cup, and it is a different measurement from brewing tea. Start at 16 oz and add more water if you want it milder. Full mixing instructions.
DO I MIX ELITE WITH HOT OR COLD WATER?
Cold. Powder sticks are not brewed. Add one stick to 16 to 32 oz of cold water, shake or stir until fully dissolved, and drink. Creatine is denser than water and settles, so shake firmly and give it a swirl halfway through.
MY ELITE DRINK TASTES TOO SALTY OR TOO TART. WHAT DO I DO?
Add more water. Zest Elite carries a 3,520mg electrolyte complex, including 1,100mg of sodium, which is what makes it taste salty at low volumes. At 24 to 32 oz per stick the salt reads as balanced rather than sharp. You cannot overdo the water.
IS ZEST ELITE VEGAN?
Yes. The creatine is synthetically produced rather than animal-sourced, and Elite is vegan, gluten free and keto friendly. Every stick is made in the USA in a GMP-certified facility.
ENERGY + HYDRATION PACKS
DO THE ENERGY + HYDRATION PACKS CONTAIN CAFFEINE?
Yes. These are the powder packs built around an energy boost, so they do contain caffeine. Zest Elite is the caffeine-free powder.
HOW MUCH WATER DO I USE PER PACK?
16 to 32 oz of water per stick, the same as Elite. That is a full water bottle, not an 8 oz cup. More water just means more hydration.
WHAT ELECTROLYTES ARE IN THEM?
Sodium, chloride and potassium to reduce fluid loss, with added glucose.
BREWING
HOW MUCH LOOSE LEAF SHOULD I USE PER SERVING?
One standard serving is 2.5 grams of tea. That’s how much you get from a tea sachet, but when using loose leaf you get the flexibility to use more or less depending on your needs or preferences.
HOW MUCH WATER TO USE PER TEA BAG?
This is for brewed tea only. One serving of tea is typically brewed with 6-8 oz of water. Some use as much as 12-15oz of water for the same amount of tea so it’s completely up to your personal preferences. We recommend starting with the standard measurements and experimenting to see what you like best. Powder sticks are different: mix one stick into 16 to 32 oz of cold water, not 6-8 oz.
FOR HOW LONG SHOULD I BREW THE TEA?
Use near-boiling water (freshly boiled water) and brew the tea for 3-4 min if brewing Green Tea, or 4-5 min if brewing Black Tea.
HEALTH & NUTRITION
DO YOUR TEA BAGS CONTAIN ANY PLASTICS/MICRO-PLASTICS?
Despite the look, our tea bags are made of a plant-fiber material that is compostable and does not contain plastics/micro-plastics.
ARE YOUR PRODUCTS SUGAR FREE?
Our hot teas are all sugar free. Our energy drinks have zero sugar flavors as well as cane-sugar flavors. Zest Elite powder sticks have 0g sugar and are sweetened with stevia. Our Energy + Hydration powder packs contain a little sugar.
ARE YOUR PRODUCTS GLUTEN FREE?
All Zest products are gluten free.
HOW MANY CALORIES/CARBS ARE IN ZEST PRODUCTS? CAN I DRINK THIS ON A KETO DIET?
