Don't put Creatine in your Protein Shake!

[SilentSurfer]

Dr. Murray J. Cohen, M.D. and President of Metabolic Nutrition said that extensive research has shown that Creatine (monohydrate or phosphate) competes with protein absorption receptors. Athletes taking combination products of these two ingredients protein + creatine) are wasting their money because the Creatine is not getting into the body.

He strongly recommends that Creatine be taken, preferably before working out, and by itself, for maximum absorption.

I didn't know this. I add creatine to my shakes all the time. Ooops. Anyone else aware of this already?

I'll see if I can find the studies he's referring to on Medline.

i take my creatine while making a protein shake.. hehe.

also when i add it into protein it wont dissolve right, there are always tiny damn creatine rocks at the bottom of my shake!

so i just take it seperately

Don't believe everything you read. If this was true then GOD would not of put creatine in red meat. Think about it! Keep it simple! That MD probley has an interest vested in that supplement company, so he'll say anything to sell more product. Watch that company will come out with some new creatine that is suppose to be taken by itself. If it works do fix it.


asone......

creatine gives me the runs.

bad creatine, bad.

i'll just say you can't believe everything you read. i started BB three years ago at 130lbs, i'm now 5'7", 180lbs, and 8%bf. i've added creatine to my protein shakes every time I use it and something is obviously working, it might not be the creatine, it might be hard work and diet, but I'll continue to add creatine to my protein shakes due to past success w/it.

Amen!!! nutrients compete for absorption all the time, sit down and have a meal, they compete, it doesn't mean it will not be absorb!!! If it is working for you, don't worry!!!

Thanks for the facts

Mr. BMJ:

Thanks for posting the study abstract. Nice to have the facts. I wonder what studies the doctor in the original post was referring to.

I've heard both sides of the story. Don't know who to believe. That's why i take it before workout w/ water, and after w/ the shake. I figure it's bound to be taken up w/ both attempts. Then i usually find another time when i'm empty stomach and take again. I don't really load.. just take creatine 3 times a day for a month. Also i'd rather take creatine a few times a day w/ less absorption than to down all that dextrose and risk getting fat for a slightly better absorption. So i'll take it more frequently.

i take it during my werkout with gatorade..
then i take it after my werkout with glutamine with gatorade..is that ok..

but for a wile i was taking it in my protein shake

Glutamine and creatine are not to be taken at the same time. Take them about an hour apart from each other

Why should you not take creatine and glutamine at the same time? I have been taking them together for about a month now. Just wondering what the reason is....

 

[Golfer18--old]

i have always taken creatine plain as day.

this is a piece of an article from Ast, written by Paul Cribb. Shows Glutamine and Creatine use different receptors.

"Molecules with similar structure to creatine were also shown not to be taken up by the cells. And while cell volumizing amino acids like taurine have similar transport mechanisms, high concentrations of taurine did not interfere with creatine uptake one bit.

This report also demonstrated that the creatine transporter is a very complex protein. It has several protein kinase phosphorylation sites (binding sites for specific enzymes) and interference with any one of these sites inhibits creatine transport to varying extents.1 This indicates that creatine uptake is an intricate, precise procedure and why it's been previously so difficult to assess creatine’s effects on a cellular level.

What do these findings on creatine mean? Possibly a lot, maybe nothing. That old, empty scientific cliché really does apply here, "more research is needed". However, some important factors have been established. Although creatine and glutamine are both dependant on the ‘Na+/K+ pump for active transport into the cell, they each utilize different transporters. This means they both have different and exclusive ways of getting into muscle cells. These may represent true anabolic pathways that may be independently manipulated to produce a permanent anabolic state within the cell.

The creatine transporter is very complex, and transporting creatine into muscle cells is dependent on many substrates and variables. It is not as simple as previously thought. Presently, I would be inclined to consider the use of both substrates at once and investigate a potent, synergistic ‘cell volumizing’ effect or, alternating cycles of the two supplements to prevent cell receptor down regulation."

So don't be afraid to combine the two...

hmm. I'm trying to find the damn abstract I read about why but it contradicts that. I can't remember how old it was either so this very well could be true.
