Query: green vibrance/green drink

Highly recommend this product. I was introduced to it by a friend who was recommended its use to help boost immunity and blood cell content. I have used this product daily for the past 5 years. I have improved my immunity against sinus infections and general sickness, my bowels are regulated, and have more consistent energy through out the day. No more afternoon lulls, feeling so much better and as a result more active.
