Tazo is a subbrand of Lipton which itself is a sub brand of Unilever. I was unable to find any English Breakfast on their website that the nutrition label stated it had 2 grams of protein. Every tea I saw had 0 listed.
Pretty popular in the US, so I do drink them from time to time and they arent bad, but I dont advise to eat the leaves when you are done. The leaves are very highly processed, and they dont really care if other things get mixed into the tea peaves before processing.
I was confused by this as well. I looked it up and couldn't find any label that had 2g of protein. The most I found was their Vanilla Chai which contains 0.1g.
