During the search to find a tea to help with intermittent fasting, we found that most fasting teas only have 2-3 ingredients and 2-3 grams of ingredients which wasn't enough to make a difference. IF Tea's Intermittent Fasting Tea combines 15 Natural Organic Ingredients that all target appetite to help fasting. Our Tea combines 4 of the most beneficial teas - Green Tea, Matcha, Black Tea and Yerba Mate. 0 Calories (and 0 Sugar or Sweetener) We combined 5 grams of natural ingredients blended into one giant delicious tea bag that you can reuse over and over throughout your day. As much natural caffeine as a cup of coffee but smoother with no crash. Good for keto and paleo as well. BREWING SUGGESTIONS: To get the most out of every cup, bring water to boiling and steep 5 - 7 minutes.
