ISO-XP is a high protein supplement with sweetener and by far the cleanest and highest quality Whey Protein Isolate available, with only 0.1g Lactose per 25g serving. Basically, there is no other protein, anywhere, which exceeds this level of clinical protein per 100g ratio – with 23.4g of protein per 25g serving. ISO-XP is made from exceedingly fresh EU, sweet dairy whey that is isolated and then spray dried. ISO-XP has NO SOY added and instead uses Sunflower Lecithin as the Emulsifier.
