Tea and Health

Teas don't all give you energy in the same way, and none of them works quite like coffee. That's what makes them useful.

The best teas for energy pair caffeine with L-theanine, an amino acid found almost only in the tea plant. Together they make you calm, focused, and alert, which feels quite different from coffee's cortisol spike and crash. Below: which teas give the most energy, how caffeine and L-theanine work together, and which of our teas suit different times of day.

How tea gives you energy differently than coffee

Coffee's caffeine hits fast and hard. It blocks adenosine receptors and drives up cortisol, your body's stress hormone. You get alert quickly, but often with anxiety, jitters, and a crash when it wears off.

In tea, caffeine works alongside L-theanine. L-theanine encourages alpha brain waves, the relaxed-focus state you also get from meditation. It doesn't block caffeine; it changes how you feel it, with a slower start, a smoother plateau, and no crash.

Research at the Unilever Food and Health Research Institute found that L-theanine and caffeine together significantly improve sustained attention, accuracy, and the ability to switch between tasks, in ways neither one does alone.

So for work that needs long concentration, tea's kind of energy is often more useful than coffee's, even with less caffeine.

Best teas for energy, by situation

For a strong morning start

If your first cup of the day has to count, drink black tea. We make three black teas that work very well in the morning.

Ruby Black Tea is bold and full-bodied, with dark cherry and cocoa notes, and gives the strongest energy of any of our teas. From CAD $10.

Gold Black Tea is smooth and full-bodied, with caramel and honey, and certified organic. Choose it if you want strong but smooth. CAD $20/50g.

Muscatel Black Tea tastes of honey and grape, with a silky texture. It's complex enough to savour and strong enough to start the day. From CAD $10.

None of the three is bitter. They grow at 5,000 to 7,000 ft in Ilam and Taplejung, where the altitude makes the leaves naturally sweet, so you don't need sugar or milk, though both are fine.

For steady focus at work

A good work tea has enough caffeine to matter and enough L-theanine to keep the jitters away. Dark Oolong strikes that balance particularly well.

Dark Oolong is 50% oxidised, with stone fruit and roasted honey notes, moderate-to-strong caffeine, and a high ratio of L-theanine. It gives a clean, focused alertness that many people prefer to coffee for deep work. From CAD $10.

The second steep of any of our black teas works well here too. It has a little less caffeine, but the leaf still holds all of its L-theanine.

For an afternoon lift that won't disrupt sleep

If you're sensitive to caffeine, skip black tea after 2 or 3pm and try one of these instead.

Floral Oolong is lightly oxidised, with honey blossom notes, gentle caffeine, and plenty of L-theanine. It's ideal between 2 and 4pm. From CAD $10.

Floral Green Tea is naturally floral, light on caffeine, and very high in L-theanine, so you get clean focus without a buzz. From CAD $10.

For late afternoon or evening

White tea has very little caffeine (15 to 30mg) and lots of L-theanine, so it's the best choice when you want something warm and mildly alerting without risking your sleep.

Floral White Tea: spring blossom, soft and velvety. From CAD $10.

Fresh White Tea: wildflower, crisp and pure. From CAD $10.

How to brew tea for the most energy

How you brew changes how much caffeine and L-theanine you get.

Hotter water and a longer steep pull out more caffeine, so for the most energy from black tea, use 93 to 95°C water and steep for 4 minutes. The first steep has the most caffeine, because caffeine comes out faster than L-theanine; later steeps lean more toward L-theanine, so the second cup of any black tea is smoother.

More leaf gives you more of both. Going from 1.5 to 2 teaspoons per 250ml makes a noticeable difference. And never pour boiling water on green or white tea: it destroys the L-theanine and makes the tea bitter without adding any useful caffeine.

Is tea better than coffee for energy?

It depends on what you need. For fast, intense alertness, like an early drive or a one-hour deadline, coffee's higher caffeine works faster. For steady focus over 2 or 3 hours, research and people who've seriously tried both consistently rate tea's mix of caffeine and L-theanine as more effective.

In practice, most people who switch from coffee to tea and give it a real two-week trial say they feel more productive and less anxious, even though they're taking in less caffeine.
