Understanding Protein Absorption
All proteins are not the same. They differ in their amino acid content, their bioavailiability, their time for absorption, and the rate at which they can be absorbed. All of these factors affect the effectiveness of a protein to raise the blood amino acid concentration. It is the rise in blood amino acids that allows the body to repair and grow muscle.
Protein is absorbed in the 3 parts of the small intestine. It is first broken apart by enzymes into peptides and amino acids and then these are absorbed by the cells lining the small intestine.
Whey isolate is digested within the first part of the small intestine and so it is absorbed the quickest. DIOXYME grass fed isolate is organic, kosher, cold processed, ultra-micro filtered whey and whey peptides.
Time for Protein Absorption
- Whey Isolate: 60-90 min
- Whey Concentrate: 2-3 hours
- Casein: 3-4 hours
- Soy: 3-4 hours
- Egg: 3-4 hours
Rate of Protein Absorption
In addition, not only is the time for absorption important, but also how much can be absorbed per hour. You can see from below that only a small amount of egg and milk protein can actually be absorbed each hour. Digestive enzymes can be added to the protein to allow for greater absorption rates and DIOXYME uses a custom blend of digestive enzymes to maximize this effect.
|Protein Source||Absorption Rate (Grams per Hour)|
|Free Amino Acids||7|
|Egg Protein Cooked||2.8|
Bioavailability is the percentage of the absorbed protein that can actually be used by your system.
The higher the number the better the protein is used.
|Protein Source||Bioavailability Index|
|Whey Protein Isolate Blends||100-159|
DIOXYME Grass-Fed Ultra Whey uses whey protein isolate and whey protein concentrate to maximize the product’s effectiveness, as those two ingredients happen to be the two most beneficial proteins available.
