Best L-Arginine + L-Ornithine

L-Arginine and L-Ornithine are two key amino acids that play an important role in bodily functions. Both amino acids induce similar effects.

L-Arginine is a precursor to nitric oxide, which is an important neurotransmitter that allows for the effective circulation of blood, oxygen, and nutrients. L-Arginine also plays a crucial role in protein synthesis.

L-Ornithine doesn’t play a role in protein synthesis but instead is a vital component of the urea cycle.

L-Arginine and L-Ornithine have been shown to:

  • Lower blood pressure
  • Increase growth hormone levels
  • Improve physical recovery
  • Reduce ammonia levels

While your body naturally produces L-Arginine and L-Ornithine, when you experience stress or illness, you require them in higher amounts. Hence L-Arginine and L-Ornithine supplements are becoming increasingly more popular.

L-Arginine + L-Ornithine Benefits

Lowers Blood Pressure

Nitric oxide is known to be a vasodilator. This means that nitric oxide widens blood vessels, promoting increased blood flow and therefore decreases blood pressure. L-arginine is a precursor to nitric oxide, and there is significant evidence that L-arginine supplementation may be able to lower blood pressure.

A meta-analysis of 11 double-blind placebo trials concluded that an average daily dose of 9g of L-arginine given across four weeks (median range) resulted in a reduction of systolic blood pressure by 5.39 mmHg and diastolic blood pressure by 2.66 mmHg.

This result is on par with what you might see through an improved diet and exercise regime, and the researchers concluded that L-arginine supplementation might be able to lower systolic and diastolic blood pressure significantly.

Increases Growth Hormone Levels

It seems that both L-Arginine and L-Ornithine may play a role in increasing human growth hormone levels. Human growth hormone is important for increasing muscle mass, reducing body fat, and increasing bone density.

One study found that arginine supplementation resulted in an increased production of growth hormone in patients who received 7g of L-Arginine. Another study looked into the combined effect of L-Arginine and L-Ornithine on growth hormone levels. They found that there was a significant increase in growth hormone levels after taking the supplements.

Reduces Ammonia Levels

Ammonia is a toxic waste metabolite, and high ammonia levels in the body can have serious negative repercussions and are often indicative of kidney or liver disease. We know that ammonia is detoxified by being converted into urea through the urea cycle, which L-Ornithine plays a crucial role in.

Low levels of L-Arginine and L-Ornithine are linked to high ammonia levels. It is thought that increased levels of both these amino acids may aid in absorbing excess ammonia. One animal study found that both L-Arginine and L-Ornithine supplementation increased the detoxification rate of ammonia.

Improves Physical Recovery

Physical exercise recovery has been linked to L-Arginine and L-Ornithine, and one study looked into its effect on recovery in a 5-week strength training program. L-Ornithine and L-Arginine were taken as either 1 or 2-gram supplements over the course of the training program. The results from the study showed that the combined supplementation resulted in significantly higher total strength and lean body mass results for participants, as well as significantly lower urinary hydroxyproline (UH) levels.

These results suggest that both L-Arginine and L-Ornithine may be able to quickly increase total strength and body mass as well as reduce the breakdown of tissue caused by chronic stress thanks to the lower UH levels.
