L-Arginine Can Increase HGH
L-Arginine can help give moderate boosts to HGH.
It should not be taken preworkout as this can reduced workout induced HGH spikes which are comparatively stronger.
L-arginine is an essential amino acid found in red meat, poultry, fish and various dairy products.
It is a popular all round health supplement that is used for a huge range of conditions.
These include, heart and blood condition such as congestive heart failure, elderly mental condition such as dementia, erectile dysfunction and a variety of other conditions.
L-arginine health benefits come from its conversion into nitric oxide which cause blood vessels to dilate and there ease blood flow in the body.
As a bodybuilding supplement it is most commonly marketed for this purpose as higher nitric oxide levels leads to better pumps in the gym. Many gym goers see it as a vital component of their pre-workout stack.
Side Effects are generally uncommon and include:
- Digestive Problems
- Allergic Reactions
- Low blood pressure
- Chemical and electrolyte imbalances
L-arginine for HGH
L-arginine is proven to be an effective natural HGH booster, despite failing to notably boost other anabolic hormones such as testosterone or insulin.
A study found that supplementing 5-9g L-arginine is able to increase peak HGH concentrations by 34.4%-120% at rest, but a higher dose failed due to stomach distress preventing absorption (2). These are generally fairly short lived spikes.
Furthermore, a review of studies (1) made the following comments:
“Recent studies have shown that resting growth hormone responses increase with oral ingestion of L-arginine and the dose range is 5-9 g of arginine. Within this range there is a dose-dependent increase and higher doses are not well tolerated.”
“Most studies using oral arginine have shown that arginine alone increases the resting growth hormone levels at least 100%, while exercise can increase growth hormone levels by 300-500%. The combination of oral arginine plus exercise attenuates the growth hormone response, however, and only increases growth hormone levels by around 200% compared to resting levels.”
From this it seems to be believed that L-arginine could cause a reduced secretion of HGH during exercise, indicating it shouldn’t be used pre-workout.
A higher daily dose of 17.5 grams of arginine in an aspartate form enhanced slow-wave sleep GH pulse by 60% (3). This is a very large dose and not recommended.
Nonetheless it seems that L-arginine before bed at a more moderate dose could be highly beneficial for HGH release.
L-arginine has a place in the HGH boosting supplement stack.
I should ideally be consumed not close to your workout as it may decrease the exercise induced HGH boost.
A split dose of 5 grams – 9 grams, one before bed and the other first thing in the morning if you workout in the evening , or 3 or 4 hours after your workout if you lift in the morning is ideal.
This is an L-arginine product I recommend:
