Protein Efficiency Ratio (PER)

PER is a measurement of a protein’s ability to increase body weight.  Research shows that protein source which is high in L-lysine will register a higher PER value. Appeton Weight Gain (Child) provides all the required amino acids fortified with L-lysine that improves the PER value.  PER with 2.5 is the standard used for nutrient labeling purposes for quality protein claims. Appeton Weight Gain (Child) has a PER value as high as 3.1.

L-lysine promotes growth and bone development amongst children.  A study conducted in Japan proved it.  A group of children were given a supplement containing 0.5g L-lysine HCL everyday.  At the end of the test, the average height and weight of the children with L-lysine supplement were recorded higher than that of the control group.  

Specificity

To generate tissue growth, our body needs specific amounts.  Without these two conditions, the normal protein synthesis will stop together (since the synthesis is such that if just one amino acid is absent, the whole system falls apart).  Appeton weight gain ensures tissues growth because it contains all the right amino acids at the right amount.

Bioavailability

Bioavailability, or biological value, measure the efficiency of a protein in promoting tissue growth upon consumption.  Research has shown that natural protein such as meat has a low and inconsistent bioavailability because it is harder to break down. Beef and chicken, for example, have a biological value of 80 and 79 respectively. Appeton Weight Gain (Adult) has a higher bioavailability because it uses whey protein, which contains a high concentration of branched amino acids that are more easily digested and absorbed. The biological value of Appeton Weight Gain (Adult) whey protein is 100 and milk protein is 88.
