Just an old dig that I pulled up, I had asked some particular ?'s about several supplements. Random discussion throughout this post about L-Carnatine. The lady supplying the information is a Medical Examiner in Ohio

Can you elaborate a bit more on the risks of taking Wellbutrin and L-Carnitine and/or L-Tyrosine.
Also , your opinion on CO Q10 WITH L-Carnitine AND D-ribose. Are there any restrictions with these combinations (and combining other supplements with them).
I've just purchased many more supplements after some research and now I'm curious that maybe I shouldn't be taking them all together.
Thank you

L-Carnitine is supposed to help control 'blood sugar' and slows down the absorption of carbs to be stored as fat. This all has to do with insulin levels. Carbs are stored in cells and can only be released by insulin. Once carbs are released, they become the glucose the body and brain runs on. If insulin receptors become desensitized though different means, carbs don't get released, don't get used for energy production, and end up getting stored as fat, causing a high free insulin blood level, blood sugar spikes, hypoglycemic symptoms, anxiety, fatigue, mental duhhhh, weight gain - sound familiar?
L-Carnitine does some other nifty stuff. It works on dopamine hard time. It increases the release of dopamine, which is normally a good thing. Dopamine is one of the 5 happy brain chemicals and it also helps with satiety which makes it good for controlling appetite. Wellbutrin also affects dopamine. It prevents the reuptake, which means it basically lets your brain soak up what dopamine you have available a lot longer. Also a good thing. But, what happens when you've got a lot of dopamine floating around that can't escape naturally (because of the Wellbutrin)? You brain gets overactive. Every lobe that's affected by the excess dopamine starts working overtime. Too much dopamine usually causes some bizarre sensory symptoms - being able to see, hear and imagine things that aren't real.
L-Tyrosine also affects dopamine. It also affects norepinephrine (another happy brain chemical). It is actually converted to both of these chemicals when the body processes it. Wellbutrin hit norepinephrine hard. It doesn't make more, but it keeps it in your brain longer. If you have too much norepinephrine can cause mania, but you'll notice extreme anxiety, jitteriness, etc...first.
How likely any of this is to happen depends on the dose of Wellbutrin and the version (IR or SR or XL). Wellbutrin has a screwy half-life. Most drugs get metabolized into one metabolite and that's what acts on your brain. Often it's not the drug you take that does the work, it's the metabolite. Some drugs get metabolized twice, so you have two things working on your brain. Not Wellbutrin, it gets metabolized into three metabolites and they in turn get metabolized again and all of that is what acts on your brain. So Wellbutrin itself has a half-life of 12-30 hours, and each of its metabolites have half-lives of 15-25, 23-43 and 24-50 hours. For this reason, it's not a good idea to take L-Carnitine or L-Tyrosine with Wellbutrin because it's metabolites are just too unpredictable. They both may be fine with the first metabolite, but whoops, you take it when the 4th one is hitting your system and it could be too much.
Does that make sense about the Wellbutrin with these supplements? L-Carnitine and L-Tyrosine (even 5-HTP) all work really well as antidepressants. If anyone wants some of the research articles and studies I have on their effectiveness, just let me know and I can email them. I know several people that weaned off their AD's after getting good effects from supplements.
Ok, moving on to the CoQ10 questions...(Sorry, this is long again, I can't stop myself, lol.)
A physician recently published a book - The Sinatra Solution - which outlines the use of CoQ10 with D-Ribose and L-Carnitine. D-Ribose increases energy production in every cell, including your muscle. It's often added to energy supplements, bars, shakes, etc... CoQ10 works in a similar way. But, both of these supplements need to be transported using long-chain fatty acids (LCFAs) across the inner mitochondria (the energy hub of a cell) into the matrix (where enzymes are made and held) to be made into energy.
L-Carnitine is the only known LCFAs transporter in the cells. It's like the fuel pump in an automobile. Your body can have all the fatty acids necessary to make energy, but without L-Carnitine, it cannot get them into the matrix of the mitochondria where the conversion of energy takes place. LCFAs are the preferred source of energy for the heart and provide 60-70% of its total energy requirements.
CoQ10 supplements with D-Ribose and L-Carnitine (you have to look at the labels, not all have this combination) are excellent for the cardiovascular system. You can combine this with all supplements and medications. The amount of L-Carnitine is usually around 65 mg, which is not a therapeutic dose for depression, it's simply enough to perform it's job in transporting the LCFAs. I've got more studies and research articles on CoQ10 than any person should be allowed to keep, if anyone is interested and wants me to email them.
