Discovering if Whey Hydrolyzed truly boosts absorption speed.
Does Whey Hydrolyzed really enhance absorption rate?
Many manufacturers claim Whey Hydrolyzed aids faster absorption, even surpassing Whey Isolate.
While advertisements tout up to 30-200% faster absorption for Whey Hydrolyzed, is the higher price justified?
To find the answer, let's consult scientists.
How fast is protein digested by the body?
Whey itself is a fast-absorbing protein, meaning it is easily digested by the body without undergoing many breakdown processes like other proteins found in food (1).
Essentially, research has found higher levels of essential amino acids when someone consumes a fast-absorbing protein compared to a slow-absorbing protein (casein). Higher amino acid levels translate to better muscle protein synthesis both at rest and after exercise.
That's why you should consume protein before and after workouts. It will increase the concentration of amino acids in the blood to deliver timely to muscles in need.
Does Whey Hydrolyzed absorb faster than regular whey?
The protein reaction is not just a typical biological reaction, which is crucial in determining whether you need to use Whey Hydrolyzed or not.
Scientist Koopman and colleagues conducted research (2) and found that there is no significant difference between Hydrolyzed Whey and regular Whey.
Below is the absorption chart comparing Casein and Hydrolyzed Whey by Tang and colleagues (3)
Here is the comparison by Pennings and colleagues (4)
Thus, it can be seen that regular Protein has double the fast absorption capacity of Casein, and Hydrolyzed Whey is not faster than regular whey by how much.
Conclusion
Based on the results mentioned above, Whey Hydrolyzed does not offer significantly superior results compared to other regular Whey types. This means that hydrolyzing Whey Protein doesn't benefit you much but costs you more when purchasing Whey to use.
So, when buying Whey, just choose Whey Isolate for use, but if your financial condition is quite well off, then any type will do.
