Does mixing whey protein with milk inhibit proper absorption? How? I’ve heard that it does. I don’t use milk, but I will occasionally mix it with plain yogurt. Will this affect absorption?
Well it may slow the time it takes to digest or get into your blood stream but as far as digestion goes your body will use the same amount of the whey protein in the yogurt or milk for your muscles.
Presence of fats slows absorption of protein, but so far as I know does not
reduce it. You just get a slower acting
but more prolonged effect.
Thank you for the info guys, but what I was trying to ask was: are there any naturally occuring sugars or anything similar in dairy that interfere with whey’s absorption?
Just Lactose. It’s really not going to hurt absorbtion. You will just see different insulin responces & absorbtion times NO Differences in AMOUNT of absorbtion. Remember Whey is a dairy by-product. Dairy products tend to be the best protein sources anyway-so They are good “stacks.”
I have actually done quite a bit of research on this subject and I have only been able to find a one study that may give any clue as to whether lactose might inhibit protein absorbtion in humans. J Physiol 1971, 217:61-70 IMPAIRMENT OF GLYCINE ABSORBTION BY GLUCOSE AND GALACTOSE IN MAN. Cook GC. In this study the presence of glucose and galactose produced a significant impairment (up to 50%) in the rate of absorbtion of glycine in the jejunum. Since lactose is broken down in the small intestine to glucose and galactose this could mean that lactose may impair glycine absorbtion. How it may effect the absorbtion of other amino acids in humans has not been determined to my knowledge; however, just the fact that it may impair glycine absorbtion is enough to deter me from using milk (which is loaded with lactose) with my protein. If anyone else has found any research on this topic I would appreciate your comments.
Its fine! Use comon sense! mixing WHEY with yogurt is something, or milk, is something, Shrugart, Jphn M berardi, & Others do all the time!
IT WILL IMPAIR NOTHING!!!
Just listen to the comon snse real world answer from John M berardi, JW, or Bill Roberts DO IT!
I would like to hear John Berardi’s opinion on this issue.
