I am taking the Vital Reds together with the Prebiotics and it is, therefore, difficult to know which product is doing what, but almost immediately I felt much more energetic and less tired and sluggish.
I was in the process of losing weight, but had reached a plateau. After starting on these products, the weight loss picked up again at a slightly accelerated pace.
My only criticism is that the probiotic powder is hard to mix. Even in a NutriBullet, it does not completely dissolve and some globs with the consistency of peanut butter remain.
Bottom Line: Yes, I would recommend this to a friend
