I am using nutrilite product for about 3 years. They delivered to costumer what they say in words.People often think that the protien powder is costlier of this company bu as I am medical professional I will explain why they are so costlier and other not. Friends protein are building blocks of our body.some are essential and non-essential.Daily food gives u non-essential but for essential you have to take from outside so nutrilite supply you this protien and to manufacture this protien is costlier.when you buy protien u should check contain if u find contain such as ( lusien, isolusien, histidine, arginine etc ) then buy that product as nutrilite have these contain.
