When people think of building more muscle they often overlook protein absorption. In order to build muscle your
body needs to synthesize more protein in the muscles than it breaks down; so your body not absorbing protein in the first place is detrimental. The body must have enough protein available to synthesize for optimal gains.
But did you know that your body may be absorbing a substantailly lesser amount than you are consuming? Due to the inhibibion of endogenous digestive enzymes from over-processing of proteins and a short intestine transit time, you could only be absorbing 15g of protein for every 50g consumed (1). Thats only 30% absorption!
The processing that happens during the manufacturing of protein powders, such as pressurized microfiltration
and dry spraying, make it more difficult for the body to break down the protein into its individual amino acids. Protein must be broken down into these individual amino acids in order to be absorbed. So the processes used can actually hinder your body’s ability to absorb and make use of the protein consumed.
This is where Aminogen® comes into play. Aminogen® is a mixture of the digestive proteases (enzymes), Aspergillus niger and Aspergillus oryzae. These two enzymes have the ability to break down proteins into their individual amino acids. This leads to easier and more absorption. Some high quality protein powders actually have Aminogen® added to them for better results.
Study of Aminogen®’s Power to Increase Protein Absorption
In a modern study of Aminogen®, Julius Oben et al. conducted a study which was published in the Journal of the International Society of Sports Nutrition. The study tested the absorption of whey protein concentrate (commonly used) with and without the supplementation of Aminogen®.
How it Was Conducted
In the study two groups of healthy male test subjects, aging 19 – 35 years old, were used. To begin each test subject consumed 50g of whey protein concentrate first thing in the morning without any Aminogen®. Following the 9 days each group then consumed 50g of whey protein concentrate first thing in the morning with 2.5 to 5 grams of Aminogen®. Each person acted as their own control and test subject. So there could not be any error due to different body’s digestion abilities.
During each part of the study the subjects’ blood was tested for amino acid (AA) and CRP (C-reactive protein) analyses at 0 hr, 0.5 hr, 1 hr, 2 hr, 3 hr, 3.5 hr and 4 hr. Eighteen amino acids were measured including alanine, arginine, aspartic acid, cysteine, glutamic acid, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine and valine.
Urine samples were tested every 24 hours to measure N2 levels. N2 excretion is used to determine the amount of protein eliminated by the body.
With the measurement of N2 levels and the measurement of serum levels of the listed amino acids, the amount of protein absorption was able to be determined.
The results of the experiment showed that the protein absorption was significantly higher with the supplementation of Aminogen®. This is able to be seen by looking at the amount of N2 excretion, which is the amount of protein being eliminated by the body. This study showed a significant decrease in average N2 excretion in the test subjects who supplemented with Aminogen® of 7.3 g compared to a much higher 10.18 g in the test subjects who only took whey protein concentrate. This is equivalent to approximately 44.6 g and 63.6 g of protein waste, respectively (1). So as you see the group who supplemented Aminogen® had nearly 20g less protein eliminated from the body. In theory that means they had about 20g more protein absorbed by the body.
Besides measuring N2 levels there were also several other analysis techniques used to support this finding.
Don’t Buy Cheap Protein Supplements
If you are buying cheap protein supplements, chances are the processing techniques used to manufacture the protein is inhibiting your body’s ability to absorb and make use of the protein. You might be better off buying a quality protein, that has Aminogen® added to it, and using less of it than you would a cheap protein supplement.
Whats the point of buying cheap protein if your body isn’t going to use a large portion of it? Answer: There is no point. Protein supplements are not created equal. You often get what you pay for.
