Tea and Health

If you've ever felt calmer after a cup of tea, you're not imagining it. Tea contains a natural amino acid called L-theanine, which research has linked to less anxiety, lower stress hormones, and a calm alertness that doesn't make you drowsy. Here's the science behind tea and anxiety, which teas work best, and why our teas from Ilam and Taplejung carry some of the highest L-theanine levels you can find.

What is L-theanine, and how does it reduce anxiety?

L-theanine is an amino acid found almost only in tea leaves (Camellia sinensis). Studies show it increases alpha brain wave activity, the relaxed but alert state linked to meditation. It also tempers the release of cortisol, the stress hormone, and encourages the production of GABA, dopamine, and serotonin.

A 2019 randomized controlled trial published in Nutrients found that 200 mg of L-theanine a day reduced self-reported stress and anxiety in healthy adults over four weeks. A cup of good loose leaf tea has roughly 20 to 50 mg, which is less than the dose in the study, but it adds up when you drink tea regularly, and the ritual of brewing helps too.

Why high-altitude Nepali tea is rich in L-theanine

The tea plant makes L-theanine in its roots, and it builds up in the young leaves and buds. Cooler weather slows the leaf's growth, which gives L-theanine more time to accumulate before harvest. Our teas come from Ilam and Taplejung at 5,000 to 7,000 ft above sea level, where the cool mountain air naturally produces leaves with more amino acids and no bitterness.

Mass-produced teas from lower gardens grow faster and end up with less L-theanine and more tannins, which cause bitterness. That's why our white and green teas taste naturally sweet and calming in a way cheap tea-bag tea doesn't.

Which teas are best for anxiety?

White and green teas have the most L-theanine, because light processing preserves it. Black teas have L-theanine too, but less of it after oxidation, and their extra caffeine can partly cancel out the calming effect.

For anxiety and calm focus, we recommend these:

• Floral White Tea has the least caffeine of all our teas, with spring blossom, soft rose, and a hint of peach and a velvety texture. It's perfect for evenings or stressful afternoons, and it's grown on certified organic farmland at Farmers Tea Co in Ilam.
• Fresh White Tea tastes of wildflower, morning dew, and cucumber. It's white tea at its purest, with minimal caffeine and as much L-theanine as possible. From Farmers Tea Co, Ilam.
• Floral Green Tea has florals close to jasmine, light sweetness, and no bitterness. Its L-theanine and moderate caffeine together give you calm focus without the jitters.
• Organic Light Green Tea is smooth, light, and low in caffeine, grown on certified organic farmland at Farmers Tea Co in Ilam at 5,500 ft. It's a great way to get L-theanine without much stimulation.

Tea for anxiety vs. medication

Tea is not a medical treatment for anxiety disorders. If you're dealing with clinical anxiety, please talk to a healthcare professional. Still, research consistently finds that L-theanine has real, measurable calming effects in healthy people, so tea can be a meaningful part of managing stress. The ritual of brewing and drinking tea also helps you slow down, which supports wellbeing in its own right.

How to brew for the most calm

Temperature matters, because high heat destroys delicate amino acids. For calming tea:

• White tea: 75 to 80°C (167 to 176°F), steeped for 2 to 3 minutes. Never use boiling water.
• Green tea: 75 to 85°C (167 to 185°F), steeped for 2 to 3 minutes. Don't boil it.

Use 1 teaspoon of loose leaf per cup. Brewing cooler and gentler also pulls out less caffeine, which is a bonus if you're prone to anxiety.

Frequently Asked Questions

Does tea actually help with anxiety?

Research shows that L-theanine, an amino acid found naturally in tea, helps you relax without making you drowsy, by increasing alpha brain wave activity and tempering cortisol. White and green teas have the most. Tea isn't a medical treatment for anxiety disorders, but drinking it regularly can help healthy people manage stress.

Which tea is best for anxiety and stress?

White tea, because it has the most L-theanine and usually the least caffeine. Our Floral White and Fresh White teas, both from Farmers Tea Co in Ilam at 5,500 ft, are especially good: delicate, naturally sweet, and very low in caffeine. Green teas like Floral Green are also excellent if you want calm, focused energy.

How much L-theanine is in a cup of tea?

Roughly 20 to 50 mg in a cup of good loose leaf tea, depending on the type, where it was grown, and how you brew it. White and green teas have the most, black teas less. High-altitude teas like ours from Ilam and Taplejung tend to have more, because slower growth lets more amino acids build up in the leaves.

Is green tea or white tea better for anxiety?

Both are excellent. White tea has a little more L-theanine and much less caffeine (15 to 30 mg vs. 25 to 40 mg a cup for green tea), so it's the better pick if you're sensitive to caffeine. Green tea pairs L-theanine with a moderate amount of caffeine for calm focus, which makes it ideal for a productive morning without the jitters.

Can black tea help with anxiety?

Black tea has L-theanine, but less than white or green tea, and its higher caffeine (40 to 70 mg a cup) can outweigh the calming effect if you're sensitive to caffeine. Even so, the L-theanine in black tea softens the caffeine, so the energy is more balanced and focused than coffee's. Our black teas are naturally sweet with no bitterness, which makes them gentler than most.

What temperature should I brew tea for anxiety relief?

Brew cooler: 75 to 80°C (167 to 176°F) for white tea and 75 to 85°C for green tea. High temperatures destroy delicate amino acids, L-theanine included, and pull out more caffeine. Cooler water keeps more L-theanine and less caffeine in your cup, which helps on both counts.
