L-Glutamine is the Most
Abundant Amino Acid in the Body by
Phil Campbell - Ready, Set, Go! Synergy Fitness for Time Crunched
L-glutamine is found in
high-protein foods like fish, beans, meat and dairy products. Research shows
that L-Glutamine helps facilitate the release of growth hormone.
After reviewing the
research concerning L-Glutamine and how it impacted growth hormone release, the
first edition of Ready, Set, GO! Synergy Fitness suggested that taking 2
grams of glutamine before training may, in the future, become a wise fitness
Well, the research
continued, and in the second edition, "glutamine before training" became a
Ready Set Go Fitness strategy.

Personally, I take 2
grams of glutamine before training. And I know many that do the same and get
Glutamine research highlights
Glutamine may have a
significant impact on the immune system. In clinical situations
and during high-intensity exercise, L-Glutamine has been shown to decrease the
incidence of infections, (The relation between glutamine and the
immunodepression observed in exercise, 2001, Castell).
Glutamine has a
positive impact on heart disease. "Glutamine may be cardioprotective in
patients with coronary heart disease," (Is glutamine beneficial in ischemic
heart disease? 2002, Khogali).
Two grams of L-Glutamine gets the job done
These studies follow
earlier research that shows only two grams of glutamine will significantly
increase HGH growth hormone. Many protein recovery drinks sold today contain up
to five grams of glutamine - so two grams may be considered a small dose.
Earlier research by Dr.
Welbourne at LSU Medical Center shows that 2 grams of glutamine is effective in
increasing HGH, "These findings demonstrate that a surprisingly small oral
glutamine load is capable of elevating alkaline reserves as well as plasma
growth hormone," (Increased plasma bicarbonate and growth hormone after an
oral glutamine load, 1995, Welbourne).
Researchers report, "All cells require glutamine as a nitrogen donor as well as an
energy source for cell-specific functions," (The
glutamine/glutamate couplet and cellular function, 2001,
What does this mean to
significantly reduces the body's supply of glutamine, and this needs to be
replaced. The pre-workout strategy of filling up the glutamine fuel tank before
training may do much more than simply help to replenish a nutrient that is used
during exercise. Glutamine may help facilitate the release of exercise-induced
What I hear most from
those who use glutamine as a pre-training strategy, "I feel stronger at the end
of a workout," (or at the end of a tennis match, a round of golf, or a long
The take home
L-Glutamine is a powerful
supplement and has many wonderful benefits. But there can be drug interactions
with glutamine supplements and some forms of chemotherapy.
You can check possible
side effects of supplements on the
National Institutes of Health website. It's always a good
idea to let your physician know what supplements you are taking.
