Vegetarianism and creatine

Answered on August 19, 2014
Created August 31, 2012 at 1:16 PM

After hearing about the mental boost afforded by creatine i decided to read some studies to bolster the hearsay with science. Ended up finding some pretty widely replicable results on the memories and cognition of vegetarians taking creatine; The results for omnivores were null. my QuESTion is in regards to something paleo has emphasized very well: incorrect definitions. What is a vegetarian? what is an omnivore? at least, what are they in the way that these studies define them. What i mean is: i was a vegetarian for many years, does that make me a vegetarian or an omnivore? Did the omnivores in the studies have previous flings with meat cessation as well? ...etc,

i want to know if my past vegetarianism ways have placed me in a group that will benefits from creatine or am i now considered a fully functional omnivore because i have been doing the paleo thing for a while...

Any help is greatly appreciated

Yeah I know that there are other possibilities. This is by far the simplest explanation, but they could have less synthesis too.

Something I've wondered is whether vegetarians benefit from creatine supps not only because they lack exogenous sources, but also because they're more likely to have a lower intake of creatine precursors (e.g. methionine). 'Tis a ponder I thought Stabby might be able to take a stab at.

especially one that tries to go the a-supplemental route

I'll add a bit of info to directly reference the question at hand. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1691485/pdf/14561278.pdf If you check out the data you'll notice an obvious drop off in mental functioning when the vegetarians washed out from the creatine supplementation, and then continued during the crossover placebo part. Now notice that this drop off was after a rather large amount of creatine taken in during the past weeks--large in terms of the amount you can get from food. So if this effect is present after big doses of creatine, how long does it last for in former veg.?

I feel like you didn't really understand the 'bolster the hearsay with science' part of my question. All you're giving me here is hearsay, evidenced by statements such as "Pretty much everyone will benefit from Creatine, weather memory and IQ function to strength and endurance"

Well the evidence that we have to base our decision upon is the studies you have read. I have read them too. What I think we can garner from them is that a certain degree of exogenous creatine benefits cognition. Vegetarians because they don't eat meat (this should be our definition of vegetarian for these purposes) benefit from a bit of creatine, because they have lower levels than meat-eaters. A meat eater in their youth doesn't benefit from creatine supplementation in that way most likely because they already have sufficient exogenous creatine from the meat that they eat. It is a matter of creatine status in the body in my view. I don't have precise figures but I would assume that any significant period of time without exogenous creatine lowers levels and thus causes one to lose the benefit that one previously had from higher levels. That is why the meat-eaters don't benefit from the supplement, they already have the benefit of the nutrient in their diet. So if you have been avoiding meat for months, maybe just weeks, I'm not entirely sure, you will benefit from either meat or creatine supplements, but if you have been eating meat for a significant amount of time then you don't need the creatine for those specific purposes, you already have enough and are already enjoying your cognitive benefit of exogenous creatine.

Whew, that's about as good an answer as I have. But the simplest answer is that exogenous creatine confers a benefit whether is be from food or creatine, but you only need so much. Having been a vegetarian for many years is less likely to matter than the amount of creatine you're getting now. My assumption is that creatine levels in the body matter to the ability to produce phosphocreatine and thus product ATP in your brain faster. Because long-term vegetarians benefit from creatine, we can pretty much deduce that there is nothing about being a long-term vegetarian that changes the benefits of a moderate intake of creatine from the diet, vegetarians only benefit from the supplement because they're lacking the nutrient already whereas meat-eaters aren't.

Creatine is found in meat.

Vegetarians don't have an external source of Creatine to my knowledge so they only have what their bodies make.

Pretty much everyone will benefit from Creatine, weather memory and IQ function to strength and endurance. Different people show different results (same as everything) try it and find out.

You are no longer a vegetarian... everyone has lapses in judgement from time to time we can't hold you accountable for the rest of your life.
