Hi,
I'm currently looking fo rthe best BCAA to take with my workouts...How is Aminolast by Gaspari? I really wanted something with BCAA and Glutamine...I notice this doesn't have it in there.
Can you guys tell me if there is a really good one with the Glutamine...should i just buy vitamin shoppe brand..they have a BCAA with Glutamine and no other addatives.
Thanks!
Why? Glutamine is 100% Bunk and a waste
Stick to products like:
Amino IV
Alpha Amino or Cor BCAA
Omega Sports Strive
Xtend
Core ABC
These are some solid intra-workout/BCAA products
how are you dosing them?? Are you training fasted or dosing between meals 4-6 hours apart? If not then you dont even really need one because those are the most optimal ways to dose BCAA's because you will most likely have food overlap from your pre-workout meal (into the post-workout period) if training fed

"The addition of glutamine to a CHO + EAA beverage had no effect on post-exercise muscle glycogen resynthesis or muscle protein synthesis, but may suppress a rise in whole-body proteolysis during the later stages of recovery."

We conclude that glutamine supplementation during resistance training has no significant effect on muscle performance, body composition or muscle protein degradation in young healthy adults.

There were no differences in the average number of maximal repetitions performed in the leg press or bench press exercises among the 3 groups. These data indicate that the short-term ingestion of glutamine does not enhance weightlifting performance in resistance-trained men.

Research with metabolic by-products of amino acid metabolism is in its infancy, and current research findings are equivocal relative to ergogenic applications. In general, physically active individuals are advised to obtain necessary amino acids through consumption of natural, high-quality protein foods.

It is concluded that, although the glutamine hypothesis may explain immunodepression related to other stressful conditions such as trauma and burn, plasma glutamine concentration is not likely to play a mechanistic role in exercise-induced immunodepression
With the exception of supplemental glutamine's beneficial role in gastrointestinal disorders (and general gut health), sepsis, and for the recovery from trauma and or surgery.... there's not much sense in administering a product that is very much limited in it's availability for physiological uptake, due to the fact that it's endogenous levels (prior to supplementation) are double the concentration of any other amino acid within the human body (1). Besides.... it's already synthesised within the body in large amounts, found in food, and found in significant amounts within a protein shake.
Endogenous glutamine plays a detrimental role in physiological homeostasis. It plays an equally important role in immune system functions, and most of the glutamine that is utilized for this purpose is naturally synthesized in vivo, and is supplied by the plasma glutamine. In healthy adults, the standard reference ranges for plasma glutamine are around 500-1000 mol/L (2), and do not require supplementation to maintain those figures.
Supplemental glutamine would only benefit us if our intracellular muscle glutamine concentrations were depleted. There are numerous studies that indicate no intracellular muscle glutamine depletion whatsoever following extensive exercise, but even if we do experience some glutamine attenuation.... we are still producing it within us, and getting it through our diet.
In healthy adults, dietary consumption of glutamine has been estimated to be around 5 grams per day (3). Foods such as meat, fish, dairy products, eggs, beans, cabbage, spinach, parsley, beets, ect. are all common sources. A single 3-oz serving of meat contains around 3-4 grams of glutamine. (4)
Now let's add on top of all that, the fact that an average 50 gram protein shake, there's about 4.5+ grams of glutamine. So for a 150 lb individual at only 2 protein shakes a day, that's around 9-10 grams of supplemental glutamine.
So for those of you that feel that glutamine is worth supplementing, we're looking at a minimum of around 15+ grams of glutamine intake per day, in addition to what is being produced endogenously.... Do you really think we need more?
