    I was feeling extremely tired and run down for months, to the point that a workout was too much to handle. Well I tarted taking tyrosine and it started to fix the problem and now I feel great. Thing is though it was in a male fuel complex by twinlabs with only 15 mg of tyrosine. The straight up tyrosine tabs had 500 mg total. Is this too much? Im not too sure how tyrosine is synthesized in the body.

    Instead of having such a large amount if it happens to accumulate would I be best off just grabbing a BCAA liquid or powder or are they basically the same as multi vitamins where most of the crucial complexes are lost? The BCAA powder is around $30 whereas tyrosine on its own is around 10. Im just wondering if anyone had noticed a boost to their performance from the BCAA.

    There is equivocal evidence for the efficacy of BCAAs and much less evidence at all for the use of tyrosine. Both are THEORIZED to delay fatigue because they are converted into dopamine in the brain. With normal exercise, you reach central fatigue partly due to the gradual shift of less dopamine and more serotonin in your brain. BCAAs and tyrosine are marketed to help by helping to increase the levels of dopamine and delaying this conversion where more serotonin is present, but the evidence is limited and is not worth spending your money on. If anything you experience a placebo effect, which is real and just as strong, with these supplements.

    Dopamine is the neurotransmitter that is released when you feel rewarded, anxious, or energetic. Serotonin is a relaxing neurotransmitter that is notably produced right before you need to take a dump because it also has an effect of causing lower GI tract motility. If you were feeling run down, check on consistent sleep cycles, over training, regular meals, and stress first. If the theory is true and there genuinely was a physiological increase in dopamine in your brain with the tyrosine supplement, then maybe it works. But tyrosine is a non-essential amino acid for most people, easily supplied in sufficient quantities if you are eating a healthy diet with enough protein spaced out throughout the day.

    Tyrosine is a conditionally essential amino acid if you are a phenylketonuric (PKU) (they do not have the enzyme necessary to convert the essential amino acid Phenylalanine into tyrosine, thereby getting a build up of phenylalanine in their system which leads to permanent neurological disorders--you would know if you are PKU because they test for it immediately after birth--if positive, you have to eat medical food without phenylalanine for the rest of your life).

    Edit: It is unlikely you will overdose even with 500 mg tabs. The toxic levels are in the 375,000 mg range. It will break your wallet first.

    In either case it had to of been something as I felt sick to my stomach and dizzy after doing a hard set of pull ups. Over training would not have been a factor at the time as I had stepped away from working out hardcore for a few months. These symptons were random and had never been experienced before in many years of working out. Anemia could have very well been the cause but I don't really believe that alone would have caused it from prior instances of sitting on the borderline of anemia and the associations seem to be drawn with adrenal function, which is a problem in my family.

    Really my question is really directed to the BCAA and their effectiveness as a workout aid. I generally buy bulk ingredients and make my workout drinks from scratch in order to cut out most of the unsavory artificial ingredients but with that a lot of the added amino acids got cut out. It seems that with BCAAs that the dosage, of maybe 15 total acids, is heavily reduced as compared to the free form pills of single acids.

    Would I be best off with the BCAAs or should I just buy a couple free forms? If so which ones work well together? The overall goal is to reduce fatigue, which glutamine really seems to take care of, but to assist in pushing out an extra couple of reps.

    Please keep in mind that I'm a vegetarian so there may be a specific acid that I could be low in that may be affecting overall performance, it is just incredibly hard to pinpoint which one.
