Tea is about taste--not bodybuilding. Buy whatever teas you like. I drink tea every single morning (loathe coffee). Hot or cold it is a great beverage and you can sweeten it to your taste. One tip: most teas don't reach their full flavor unless they seep for a few hours. When I pour myself a cup in the morning, I let the remainder seep for the rest of the day. When I come home it is so much stronger and more flavorful. That's when you pour it over ice and really enjoy it.
