One of the little known effects of l-glutamine supplementation is increased human growth hormone levels. Not a bad effect for an unsexy supplement like glutamine.
I’ve already spoken about the importance of l-glutamine in your post workout shake, and I’ve spoken about the powerful effects of a cyclical ketogenic bodybuilding diet in keeping human growth hormone chronically elevated.
We can also elevate growth hormone while we sleep by taking as little as 2 grams of glutamine before snoozing. Check it out: (If you can’t be bothered to read the whole study, the red text at the end will do).
Increased plasma bicarbonate and growth hormone after an oral glutamine load
American Journal of Clinical Nutrition, 61: 1058-1061, 1995
An oral glutamine load was administered to nine healthy subjects to determine the effect on plasma glutamine, bicarbonate, and circulating growth hormone concentrations. Two grams glutamine were dissolved in a cola drink and ingested over a 20-min period 45 min after a light breakfast. Forearm venous blood samples were obtained at zero time and at 30-min intervals for 90 min and compared with time controls obtained 1 wk earlier. Eight of nine subjects responded to the oral glutamine load with an increase in plasma glutamine at 30 and 60 min before returning to the control value at 90 min. Ninety minutes after the glutamine administration load both plasma bicarbonate concentration and circulating plasma growth hormone concentration were elevated. These findings demonstrate that a surprisingly small oral glutamine load is capable of elevating alkaline reserves as well as plasma growth hormone.”
2 grams at bedtime would prove useful. 90 minutes after digestion (while you’re asleep) your growth hormone levels will start to rise. Also, it may be beneficial to take this small dosage pre-workout as well. It’s such a small dosage and such a cheap supplement that you really can’t go wrong!
