It is similar to the way green grass smells when you are mowing it.
BrainON has a more intense green flavor than E3Live does. BrainON supreme is an even more intense concentrated green flavor.
We do have apple & lemon flavored for those that want a sweetened, delicious taste. The apple lemon flavor is organic frozen fruit juice concentrate, so if you do not want additional sugars, then we recommend the unflavored frozen algae.
If you are unsure, we always ask, are you taking E3Live or BrainON for the pure benefits, or for the taste? That usually directs you to what is best for your individual needs.
