Glycine – Amino Acid For Sleep, Energy & HGH

Glycine Increases HGH

Glycine is very effective at boosting HGH with dose dependant increases.

Improving sleep quality and duration via glycine can indirectly also increase HGH.

For its price it is definitely worth supplementing.

About Glycine

Glycine is a simple proteinogenic amino acid and has a range of physiological functions.

It is used as a biosynthetic intermediate and an inhibitory neurotransmitter. It is used in many products as an additive such as sweetening food and buffering cosmetic products.

It is found in lean meats, eggs, fish, nuts beans and dairy.

Glycine in Bodybuilding

In bodybuilding it is most favoured for its muscle boosting effects as an amino acid and also its ability to help sleep.

It has been shown to increase protein synthesis and skeletal muscle growth in pigs (1).

This improved sleep is claimed by users to elevate mood, focus and weight loss which will create more drive in the gym and a more aesthetic physique

Side effects a rare but include gastrointestinal effects such as:

  • Soft stools
  • Nausea
  • Vomiting
  • Stomach upset

Therapeutic doses range from 2g to 60g. It’s important to start with a low dose and increase over time to monitor side effects.


Does glycine increase HGH?

One study (2) found that 22.5g of glycine increases HGH for up to 3 hours after ingestion in healthy volunteers.

The 3.6 fold peak occurred at 90 minutes and first started just 5 minutes after ingestion.

Another study (3) tested doses of 4g, 8g and 12g on healthy subjects. They found that significant boosts were found in a dose dependant manner.

The Verdict

Glycine has relatively potent HGH boosting effects for a supplement.

It is a popular choice for a bodybuilder as it is seemingly anabolic.

This comes from its a ability to increase protein synthesis as well as HGH.

This is a glycine product I recommend:
