I totally believe this because I drink a lot of tea, am allergic to
wheat, have been on a nervous edge and find benefit from taking B
supplements. But I have a different question.

When you say 2-3 liters a day, do you mean 4 grams of leaves in a 4 oz
gaiwan that you brew 6-8 times is a liter, or do you mean 4 grams of
leaves 8 times in a day? Concentration makes a difference I think.
