Anyone know of an unsweetened bottled green tea that does NOT contain vitamin C or citric acid?

Question
I know that ascorbic acid (Vit C) is used as a preservative, but it hurts my belly if I drink too much of it, yet I love bottled, UNSWEETENED green tea! Does ANYONE know of a brand of it that doesn't have vitamin C or citric acid? It also needs to be unsweetened or diet. Thanks! Petoria, what is the brand name? Any size is fine.
Answer
they have some in trader joes but its like a big bottle not a personal sized one
