L-Glutamine – An Amino Acid That Could Boost HGH

L-Glutamine Has Promising HGH Potential

This is a very popular amino acids for its anabolic properties.

In regards to HGH it has promising evidence that frequent dosing throughout the day can keep HGH levels elevated.


What is L-Glutamine?

L-Glutamine is an amino acid that is conditionally essential, meaning the body can usually make enough of its own, but at times of stress additional supplies may need to come from diet.

It is used to synthesize proteins in the human body (1). It has become a mainstream supplement because of this ability  when muscles are damaged during a workout and therefore increase skeletal muscle mass.

As well as this it can help increase the volume of muscle cells (2).

This means it induces both sarcoplasmic hypertrophy – cell size growth and myofibrillar hypertrophy –  cell number growth in muscles, which provides accelerated results.

Even the current 7 time Mr Olympia, Phil Heath has the supplement as a part of his bodybuilding regime. Other benefits include:

  • Improve gastrointestinal health
  • Heal leaky gut
  • Improve memory, focus, concentration
  • Improve IBS
  • Improve diabetes

A review of 4 studies of glutamine found the supplement to be safe in adults (3).

No side effects have been reported in adults but proceed with caution as higher doses as its still relatively unknown what they could do.

A standard dose is 10 to 15 grams a day between two or three doses.


L-Glutamine increase HGH

L-glutamine is theorized to increase glutamate and arginine concentrations which in turn can increase HGH secretion.

A study investigating this idea in 2008 found that 2 grams of L-glutamine was able to boost growth hormone 90 minutes after ingestion in all but one of the 9 participants.

Therefore spread out doses of L-glutamine throughout the day around your workouts should keep your HGH levels nicely topped up.

The Verdict

If your serious about increasing natural HGH levels then supplementing L-glutamine certainly won’t hurt.

Natural HGH boosting results come mostly from sleep, diet and training.

But for those who want the edge from a supplement for a reasonable price, L-glutamine is a sound natural method of boosting HGH.

This is a L-glutamine I recommend:
