According to Zest Tea, its tea products have more caffeine than coffee but without a crash; has all-natural ingredients and almost no sugar.

The company further asserts that its products are GMO- and gluten-free and can help you focus better and be more productive every day.

Let’s look at what it contains.

  • Carbonated Water
  • Cane Sugar
  • Black Tea
  • Stevia Leaf extract
  • Steviol glycosides
  • Organic erythritol
  • Citric Acid
  • Natural Flavors
  • Sodium Citrate
  • Green Tea Extract
  • L-theanine
  • Vitamin B3
  • Vitamin B5
  • Vitamin B6
  • Vitamin B12

I’ll explain briefly some of the ingredients that are indeed notable in this beverage namely; stevia leaf extract, green tea extract, and black tea.

Stevia Leaf Extract

The stevia plant provides sweetness without adding calories. Steviol glycosides, the primary elements that deliver stevia its sweetness, are found in the leaves.

A natural sweetener called stevia has been linked to many advantages, including lower blood sugar levels. Stevia is a great alternative to refined sugar because it has few side effects and can be used sparingly.

If you have diabetes, using stevia to sweeten yogurt or hot tea could help you avoid consuming additional carbohydrates.

If you’re looking for sugar-free energy drinks, I have some good recommendations for you in this article.

Black Tea

The leaves of a plant called Camellia sinensis are used to make black tea.

Black tea is rich in antioxidants and contains stimulant properties like caffeine. The leaves change from green to a dark brownish-black colour through a process known as oxidation.

According to the Tea Association of the US, approximately 84% of tea consumed in the United States in 2018 was black tea.

Studies, however, have focused specifically on black tea and how the oxidation process might affect health.

Here are the benefits of black tea:

  • increased in alertness and energy
  • reduces the risk of cancer
  • improved gut health
  • improved metabolism

Green Tea Extract

Green tea extract is essentially a concentrated version of a beverage produced by brewing dried green tea leaves.

It does contain caffeine and is jam-packed with phytochemicals called catechins and antioxidants.

Green tea extract has been shown in numerous studies to support weight loss, blood sugar control, disease prevention, and exercise recovery.

Additionally, it can lower fat blood levels, control blood pressure, improve brain health, and keep your skin and liver healthy.

You can get green tea in different forms: powder, capsule, and liquid.

How much caffeine is in Zest Energy Tea?

One can of Zest Energy contains 150mg of caffeine.

To increase alertness and improve physical performance, caffeine is added to a variety of beverages including tea, coffee, and green tea.

The FDA advises against consuming more than 400 mg of caffeine per day for adults who are healthy. Going overboard can lead to the following side effects:

  • anxiety

  • dizziness

  • high blood pressure
  • increased heart rate

Each serving of Zest Energy contains 14g of sugar.

The American Heart Association advises against consuming more than 24g (100 calories) of sugar per day for women and 36g (150 calories) per day for men.

The following are some detrimental outcomes of consuming this much sugar:

  • weight gain

  • tooth decay
  • skin ageing
  • increased risks of heart disease
  • increased risks of cancer

I think the amount of sugar you get from Zest Energy Tea is still within the healthy limit. As long as you keep your intake to a serving per day, you’ll do just fine.

The canned version of Zest Tea has the following flavours:

  • Zest Energy Tea contains three times as much caffeine as a typical cup of tea. The tea offers a slower, more gradual release of energy, so this is essential to how it functions.
  • It has a fair amount of sugar and caffeine in it. So you might want to avoid this drink if you have diabetes or experience any hormonal reactions to sugar.
  • On its website, Zest Tea acknowledges that drinking tea does not always result in weight loss. According to the company, weight loss may be aided by tea consumption in addition to a healthy diet and regular exercise.
  • It comes in a variety of flavors which have been acknowledged as having a refreshing taste. It is a bit expensive so you might want to try out the samples costing $9.99 first, before actually purchasing them.
  • Therefore, I give Zest Tea Energy an 8 out 10 score.
  • If you’re keen to try a different energy drink with low caffeine, go for REIZE Energy!
