Similac is great, but this product is not much different from other things alike currently on the market.  This product is expensive and I had no positive effects at all from it.  My daughter did not like the taste and I did not like the smell.  For the price I would never buy it again and I am sure not about to give any recomendations to my friends about this product.  I think this product will only make it for a little while in stores.  Waste of good money when buying this product.
