Amway the company that makes and sell the product was founded in 1959, that a long time business. You can buy the producf from official site aur from outside retailer. I purchase amway nutrilite fibre of 200gm for 850 rs which is very expensive, normal people can not efford this much expensive product and that too the product will took a lot time to give any effect in your health. Personally speaking I didnt feel any kind of change in my body or health.some one recommended me for this.but there was not any improvement in health.it might be good product but it didnt help me.and I cannot efford so much of expensive product to improve my health.aur wo bhi is mehngai me.
