We have called this product Premium 5 because there are 5 high quality sources of protein in this great tasting protein powder. There is nearly 30% of the protein coming from high quality hydrolysed collagen and the same amount from instantised ultra-filtered whey protein isolate. These form the largest percentage of the protein within the Premium 5 protein powder. The next largest component is the instantised ultra-filtered whey protein concentrate at just over 15% per serve. These 3 are added to provide ‘fast’ digested and absorbed proteins. Next comes the calcium caseinate which forms just over 15% of the product and is added as it is ‘slow’ digested and absorbed protein. Finally just over 6% of the protein content comes from ultra-filtered milk protein concentrate which fills in the gap between ‘fast’ and ‘slow’ digested and absorbed protein and can be classed as ‘medium’ absorbed and digested protein. We have tried to make this as comprehensive a product as possible with a broad variety of amino acids that are bio-available. By endeavouring to provide a wide spectrum of protein sources, we maximise the amino acid profile also with the different digestion rates we endeavour to make sure that optimum levels of amino acids are available in the bloodstream for absorption by the muscles and cells to maximise the effectiveness of this protein supplement.
