Green tea – effects, caffeine & enjoying it sugar-free

May 24, 2026Teaballs

Green tea is one of the healthiest drinks in the world – rich in antioxidants, gently invigorating thanks to natural caffeine and versatile in use. Here you will learn everything about the effects of green tea, how much caffeine it contains and how to enjoy it easily and sugar-free with TEABALLS.

Green tea effects – the most important benefits

Green tea (Camellia sinensis) is oxidised less than black tea – which preserves more catechins, particularly EGCG (epigallocatechin gallate):

  • Antioxidant: EGCG is one of the most powerful plant antioxidants – it protects cells from free radicals.
  • Gently invigorating: it contains caffeine plus L-theanine – the combination produces calm, focused energy without caffeine jitters.
  • Metabolism: studies show a slight increase in fat burning with regular consumption.
  • Brain: L-theanine promotes alpha waves in the brain – better concentration and relaxation at the same time.
  • Heart health: regular green tea consumption is associated with a lower risk of cardiovascular disease.

How much caffeine does green tea contain?

Green tea contains around 25–50 mg of caffeine per cup (200 ml) – less than coffee (80–120 mg), but enough to give a gentle lift. Thanks to L-theanine the caffeine feels more balanced than in coffee – no racing heart, no crash.

TEABALLS Green Tea contains the same natural caffeine as loose tea leaves – without sugar, without additives.

  1. Drop one TEABALL Green Tea into the glass
  2. Add water at 70–80°C (not boiling – this protects the catechins)
