Is Spearmint Tea Caffeine Free?
By Khawaja Saad Aslam · · Updated · 2 min read
This is one of the most common questions we get about spearmint tea: is spearmint tea caffeine free? The answer is simple: yes.
Yes — Spearmint Tea Is Naturally Caffeine-Free
Spearmint tea contains zero caffeine, because it's made from the leaves of the spearmint herb, not from the tea plant (Camellia sinensis) that green, black, and white tea all come from. Caffeine is naturally present in the tea plant — spearmint simply doesn't contain any.
Why This Matters
Caffeine-free status matters for a few practical reasons:
Evening drinking — you can drink spearmint tea at night without worrying about disrupted sleep.
Pregnancy and breastfeeding — many people specifically look for caffeine-free options during these periods, though you should still check with your doctor before making any herbal tea a regular habit.
Sensitivity to caffeine — if caffeine causes you jitters, anxiety, or sleep issues, spearmint tea is a genuinely caffeine-free alternative to regular tea.
Children — caffeine-free status is one factor (among several) parents consider, though any herbal product for children should be discussed with a doctor first.
How to Verify It Yourself
Always check the ingredient label. A genuinely caffeine-free spearmint tea should list only spearmint leaves — if a product lists green tea or black tea alongside spearmint as a "spearmint blend," it will contain caffeine from those ingredients. Spearmint Tea lists exactly one ingredient: 100% pure spearmint leaves.

How Spearmint Compares With Other Drinks
For perspective, a cup of green tea typically contains roughly 25-50 mg of caffeine and black tea around 40-70 mg, while brewed coffee averages about 95 mg — all depending on the leaf, brewing time and cup size. Spearmint tea contains none of it, which is why it's often chosen as a warm, flavourful replacement for an afternoon or evening cup.

Yes. Because it contains no caffeine, it is a common choice for the evening. As with any herbal tea, check with your doctor first if you are pregnant, breastfeeding or take regular medication.
