Coffee vs. Matcha: The Science Behind Coffee Jitters

In recent years, matcha has transcended from an ancient Japanese tea ritual to one of the most popular drinks in the UK. A great choice for those seeking sustained energy lift without the coffee jitters, latte lovers are switching their coffee for matcha in their droves as they look to curb their caffeine consumption and reap the wellbeing benefits of matcha’s rich antioxidant properties.

But why is matcha good for you? Dr Jenna Macchiochi spills the beans as she delves into the science behind the caffeine jitters and explains why, if you’re caffeine sensitive, matcha is the low-caffeine tea to try.

How caffeine causes the jitters: The science explained

Does caffeine give you the jitters? You’re not imagining it. Many people are sensitive to caffeine and find that drinking too many cups of coffee or cans of caffeinated energy drinks can leave them feeling unsettled, perhaps even a little anxious and overstimulated.

So why do we experience caffeine jitters? Dr Jenna Macciochi explains the science.

“Caffeine can make you feel jittery because it is a stimulant that blocks adenosine, the brain chemical that helps you wind down. Instead, your brain gets the signal to stay alert.

At the same time, caffeine also contributes to a rise in cortisol stress signals and stimulates the nervous system, increasing the release of activating chemicals such as norepinephrine and adrenaline. This is what gives you that “switched on” feeling.

Of course, not everyone reacts the same way to caffeine; genetics and metabolism both play a part in determining whether you experience coffee jitters or not. 

Often, caffeine is absorbed quickly, which can result in a rapid rise in energy followed by a subsequent dip later. However, some people metabolise caffeine slowly, which can lead to longer-lasting effects.

Matcha mania: Green tea energy without the cortisol spike

Now that you know why we get the caffeine jitters, how can you get that energised lift without turning to coffee or energy drinks? 

Enter matcha, a vibrant green powdered tea that has rapidly risen in popularity in the UK thanks to its clean, jitter-free caffeine power.

Derived from the leaves of Camellia sinensis, the same plant used to produce green tea, matcha is grown and harvested in a way that leaves it enriched with powerful antioxidants such as Epigallocatechin gallate (EGCG).

It's also rich in L-theanine, an amino acid that provides a sense of calm in response to the stimulating effects of caffeine, more about that later. 

Coffee vs. matcha

We’re often asked whether matcha is healthier than coffee, and to that we say both have their benefits. However, if you are caffeine-sensitive, prone to feeling anxious or have a slow caffeine metabolism, matcha may be the best choice for you.

Here’s a snapshot of how the two compare:

While matcha is not entirely caffeine-free, it is considered to offer a natural and clean caffeine source. That’s because, unlike coffee, matcha powder contains L-theanine, an amino acid that provides a sense of calm alertness against the stimulating effects of caffeine on the body's nervous system.
Research has shown that the L-theanine in matcha works synergistically with caffeine, promoting a feeling of relaxation and mental clarity, helping to foster a state of tranquillity and alertness within 30 to 40 minutes of ingestion. 
So it’s not that Matcha is “caffeine-free,” or better than coffee, but it may just offer a less-jittery experience for those who find the caffeine in coffee overwhelming.
