So I just put in a new order for about a 3month supply of ATW blend and Kent's Glutamine peptides.
I know the debate about whether Glutamine is a waste of money, studies showing no effect on weight training and other studies showing it increases HGH by 400%. As I am in my middle-age, the HGH effect seems valuable.
But here is my concern: The following link here (http://www.youngagain.com/glutamine1.html)
reports:
"In another study, nine healthy volunteers ages 32 to 64 were given either a beverage containing 2 g of glutamine or a placebo drink. During the next 90 minutes, blood samples were collected and measured for bicarbonate and plasma growth hormone--two substances stimulated by glutamine. Subjects who consumed supplemental glutamine showed significant increases in glutamine (12 percent to 19 percent above presupplement levels), bicarbonate (12 percent) and growth hormone (up to 430 percent), whereas those drinking the placebo beverage showed no changes. (cite to Welbourne, T.C. "Increased plasma bicarbonate and growth hormone after an oral glutamine load." Am J Clin Nutr, 61: 1058-61, 1995.)
"Its ability to boost growth hormone levels (up to 430 percent) is a case in point. Growth hormone helps build and strengthen muscles and clear acid from body fluids, but starting at age 30, its production declines. This decline is associated with muscle loss (muscle breakdown is accelerated under acid conditions), increased body fat and accelerated aging. (citing to Rudman, D., Kutner, M.H., et al. "Impaired growth hormone secretion in the adult population: Relation to age and adiposity." J Clin Invest, 67: 1361-69, 1981)
"Glutamine supplements may help delay such developments.
However the same report goes on to say:
"Two final points are important for the glutamine story. First, too much glutamine may be counterproductive. In humans, more than two grams is likely to result in less growth hormone production, less bicarbonate buffer, and probably no further energy benefit. In fact, elevated doses may overstimulate brain neurotransmitters and be dangerous. So, while some glutamine may be beneficial, large amounts may be a waste of money and even harmful.
"Secondly, most of the glutamine studies appearing in scientific journals are conducted with isolated cells or animals. More human clinical research is needed to fill in missing pieces of the glutamine puzzle. Nonetheless, glutamine's emerging picture is exciting and cause for optimism. It may become an essential supplement for consumers in years to come." (I just included this second point for interest.
I just checked out my ATW blend. Each scoop contains more than 4!grams of Glutamine! So does the Whey and Milk Isolate
My food plan already includes 2-3 scoops of the powder a day :eek: and I was planning to subplement my glutamine consumption with 2 grams of Kent's glutimine peptides. :eek: :eek:
Anyone have any thoughts?
Particularly Kent and ATW--can you respond? have you guys sent my order out yet?
