Yes, this product is likely to contain some caffeine, because black tea extract is one of its key components. Black tea naturally contains caffeine, and the extract used in an instant tea would normally carry that caffeine into the drink. The product description does not state a specific caffeine amount, so if you are sensitive to caffeine or trying to limit it, check the full ingredient and nutrition information on the packaging before use.
If you are avoiding caffeine entirely, this tea may not be the best choice. In that case, look for a product that explicitly states it is caffeine-free. If you are only trying to reduce caffeine, you can still enjoy this tea in moderation, but keep in mind that the exact strength depends on the extract used and the amount of water you add. Water dilution does not remove caffeine; it only changes the taste intensity.
As with any beverage containing caffeine, it is sensible to consider your overall daily intake from tea, coffee, cola and other sources. If you have a medical condition that requires limiting caffeine, or if you are pregnant or breastfeeding, consult a specialist before including this drink in your routine.
