For about a couple of months now, I have been mixing in 4-5 teaspoons of sugar-free Metamucil with my protein shake (ON whey isolate). I recently read a study that found large amounts of fiber can block absorption of nutrients in the intestines, to the tune of 7 calories per gram. I am taking about 20g of fiber at a time, with 25-35g of protein.
So it only recently occurred to me that the fiber might be binding or blocking absorption of the protein. Anyone know anything about this? I want to keep taking the fiber supplement, but I don't want to be counterproductive if mixing in protein is a waste. And if it is, how long should I wait to take protein after taking fiber?

Firstly, why don't you spread out your fiber intake throughout the day, and get it from real sources rather that powder stuff.
And no, it won't 'block' its absorption. Maybe slow it down? I'm not a nutritionist so I may be wrong.Go ahead, make fun of me being a light weight! I like me, that's all that matters.

Fiber does slow absorbtion, but that's not a huge deal depending on when it is eaten in relation to your workout. Eat more veggies throughout the day and fiber supps will become a thing of the past.

Insoluble how ever you spell it, helps speed up the metabolism
soluble which tends to more in vegetables will help slow digestion and help you poop.

insoluble is what aids your poos, it doesn't "speed up" your metabolism, and veggies are the biggest source of insolubleOriginally Posted by loupenguin

I'm not big on fruits and vegetables, other than what comes incidentally with my meat....which is one of the reasons I supplement fiber. Mainly though I like that it makes me feel full for hours. Less than 20 grams at a time, and I don't feel as full.
Mixing the fiber and sucking it down before it gels is not the most pleasant experience; I don't think I want to do it more than twice a day. Plus it's messy as hell.
If it only blocks some of the whey protein, I figure I can probably just overcompensate and add a little more powder in. If it blocks most or all of it, I need to change my strategy.
I believe Metamucil is evenly split between soluble and insoluble. I don't really care about the laxative effect, although that is noticeable. I mainly like all the other benefits of fiber supplementation.
Thanks for the replies so far....
