Ken asks…

Why and How does green tea and L-Carnitine help on weight management?

There is a food supplement in our local drugstore containing 250mg of green tea extract (EGCG) and L-Carnitine 250 mg. There are people I know who actually lost weight gradually from 5 to 10 lbs in 2 weeks. With Diet and Exercise. How does it work? And how many milligrams are really needed per EGCG and L-Carnitine?

Linda asks…

Are there long term effects of supplementing glutamine or BCAA or Carnitine?

I’ve recently started taking L-Glutamine and Branched Chain Amino Acids for weight lifting and working out. I’ll also be getting into carnitine when I start cutting down.

My question is, are there any long term side effects for these three supplements? And will there be defficiencies when I decide to stop supplementing (as the body will no longer produce, because it’s been supplemented for so long)? And this brings me to another question (I’ve asked in diet/fitness category also), do you need to cycle any of these supplements?

And please, I would like to know facts and not just opinions. Thanks in advance!

I’ve had good effects from glutamine on liver–it’s supposed to be good, but I don’t know about the rest. Carnitine is found in meat, so it shouldn’t be bad for you. Here is what I looked up online and found:

Blood concentrations of branched chain amino acids (BCAA; leucine, isoleucine, and valine) and glutamine (Gln) decrease markedly in sepsis. We investigated the effect of carnitine on serum concentrations of BCAA and Gln in fasted septic rats. Rats were made septic by cecal ligation and puncture. They developed extremely high blood concentrations of endotoxin, and serum concentrations of BCAA and Gln were markedly decreased 2 d after the operation. When L-carnitine was administered subcutaneously to the rats at 500 mg/kg body weight every 12 h for 2 d starting at the operation, no decrease in the serum concentrations of BCAA and Gln was observed. This indicates that the administration of carnitine can prevent the decrease of serum concentrations of BCAA and Gln in septic animals.

John asks…

What can you do to detect Carnitine Deficiency? Prenatal or later in a persons life.?

So, what kind of tests can you have done to tell if your baby has Carnitine deficiency? Would you have to wait until after they are born or can you tell by prenatal tests?

admin answers:

I think the tests are done only after birth. Check here.
