Me gusta por no tener sabor
Me gustó pero es muy poco el contenido. Creí que traía dos unidades y no. Creo que me confundí. Me gusta porque es sin sabor y puedes utilizarlas con diferentes bebidas sin alterarles el sabor. No puedo hablar mucho del resultado porque al ser poca entiendo que debía tomar por mas tiempo.

Great for my belly!
I love this stuff! It helps with digestion and helps me stay full till my next meal! I like to add a sugar free juice packet and then Bubly for a little zest! Its clear. No taste. No grit.
