There is 80 mg of natural caffeine from green coffee bean in each 1oz serving of Lotus Energy Concentrate. 

The difference in the flavors are the super fruits we use in each different Lotus product.
White Lotus - Our proprietary Lotus Energy blend without the addition of super fruits
Red Lotus – Our proprietary blend with Tart Cherry (plant based formula closest to Red Bull)
Blue Lotus – Our proprietary blend with Blueberry and Acai Pink Lotus – Our proprietary blend with Tart Cherry and Red Raspberry
Purple Lotus – Our proprietary blend with Elderberry and Black Raspberry

Unfortunately we do not have smaller sizes available. A lot of businesses serve Lotus Energy Drinks. Please visit our store locator to find a place near you who may serve Lotus Energy Drinks.
