Coffee or tea: Which is really better for your health and energy?

1. Introduction: The age-old question – coffee or tea?

Coffee or tea? It is a question that divides opinion and is a daily ritual for many. Some swear by coffee’s powerful kick, while others appreciate tea’s gentler stimulating effect. But what is really better for our health, focus and wellbeing? And what can you do if your beloved coffee gives you heartburn?

In this article, we take a deep dive into the worlds of coffee and tea. We compare their health aspects, look at the problem of heartburn and introduce a revolutionary alternative that brings together the best of both worlds: Guayusa. We’ll also show you how to save smartly at GUYA without tying yourself into rigid subscriptions.

2. Health check: What the science says

Both coffee and tea have demonstrated health benefits in numerous studies. Both contain antioxidants, especially polyphenols, which can protect the body from free radicals and inhibit inflammation. But there are important differences.

A study by Harvard Health Publishing confirms that both drinks are associated with a longer life and a lower risk of cardiovascular disease [1]. Tea’s key advantage, however, is the amino acid L-theanine. It counteracts the caffeine rush that can feel jittery and promotes a state of relaxed alertness. That is where our alternative comes in.

3. Heartburn from coffee? Help is on the way!

A question we often hear is: “Are there particular coffee beans or varieties that cause less heartburn?” The answer is yes! Heartburn after drinking coffee is a widespread problem, usually caused by a combination of caffeine and acid. Caffeine can relax the lower oesophageal sphincter, making it easier for stomach acid to rise.

Here are three tips to help avoid heartburn without giving up your pick-me-up:

1. Choose lower-acid beans: Arabica beans are naturally lower in acid than Robusta beans.
2. Pay attention to the roast: Dark roasts are gentler on the stomach because more acids break down during the longer roasting process.
3. Try cold brew: The coffee is cold-extracted, making it up to 70% less acidic than hot-brewed coffee.

Or switch to an alternative that is naturally gentle on the stomach. That brings us to the star of this article.

4. The superior alternative: Why Guayusa wins

Imagine a drink that not only combines coffee’s stimulating power with tea’s balancing effect, but amplifies them. That is Guayusa (Ilex guayusa), an Amazonian superfood traditionally drunk by Kichwa Indigenous people as a “night watch” tea.

This unique combination, together with an abundance of antioxidants, makes Guayusa the perfect choice for anyone looking for more than a simple pick-me-up. Scientific studies suggest Guayusa may improve cognition, regulate blood sugar and have antioxidant effects [2, 3]. Unlike coffee, Guayusa is not acidic and is therefore exceptionally gentle on the stomach.

For coffee lovers who don’t want to miss out on the taste, we have even developed Guayusa Coffee Powder. And if you want to experience the pure power of the coffee fruit, try our coffee cherry tea (cascara) – another fantastic, low-acid alternative.
