Best L-Ornithine

L-ornithine – or just ornithine – is a non-essential amino acid that’s obtained from the diet and made in the body from an amino acid called L-arginine. Ornithine is a non-protein amino acid – meaning it isn’t involved in protein synthesis like most amino acids. Rather, it’s involved in many other important metabolic processes.

Ornithine is also available in convenient powder and capsule form. It’s often sold in combination with the amino acid L-arginine, which improves the absorption of ornithine and enhances its effects.

L- Ornithine Benefits

Supports Detoxification

L-ornithine plays a key role in detoxification. It’s involved in the urea cycle which detoxifies ammonia from the body. Without sufficient ornithine, we could face potentially dangerous ammonia toxicity.

Ammonia is a waste product produced as a by-product of protein metabolism and is toxic if allowed to build up in the body. L-ornithine supports the liver in converting ammonia into urea so it can be removed from the body via urine. If you supplement with ornithine, you may have increased urination for this reason.

Improves Sleep

Quality sleep is absolutely vital for our body and mind to rest and regenerate. Lack of sleep is a major risk to mental and physical health and reduces our productivity.

Animal and human studies using l-ornithine suggest it regulates the sleep-wake cycle and improves sleep quality, possibly by lowering the stress hormone cortisol.

A 2014 study on adults with a history of mild stress found that taking 400mg of ornithine for eight weeks reduced cortisol levels and improved sleep quality and mood.

Speeds up Hangover Recovery

L-ornithine may be useful for beating symptoms of a hangover quickly, possibly by supporting detoxification and enhancing sleep quality.

An interesting study on healthy Japanese adults found that 400mg of L-ornithine half an hour after drinking resulted in fewer unpleasant physical and emotional symptoms the following morning.

Regulates Blood Pressure

Ornithine may support heart health by indirectly regulating blood pressure

It’s involved in the production of l-arginine, an amino acid that is vital for healthy nitric oxide levels. Nitric oxide is a gas produced by the endothelial cells of the blood vessels. It’s a vasodilator, meaning it relaxes the elastic blood vessel walls and allows them to expand and improve circulation and regulate blood pressure.

Boosts Physical Performance

L-ornithine is a popular amino acid among athletes and bodybuilders and can be found in many fitness supplements.

Ammonia levels accumulate during endurance exercise, impairing energy production and worsening muscle fatigue. So, by detoxifying ammonia from the body during exercise, supplementing with ornithine reduces fatigue, boosts performance and supports recovery.

One study on healthy trained adults found that taking ornithine significantly increased peak reps per minute (RPM) when performing sets of intense cycling.

Encourages Muscle Growth

Ornithine may promote lean body mass, healthy muscle growth and strength – especially when combined with L-arginine. One study on men undergoing a 5-week intense strength training program found that taking a supplement containing L-arginine and L-ornithine increased measures of total strength and lean body mass.

This may be due to an increase in human growth hormone (HGH), an anabolic hormone released by the brain that promotes cell repair and muscle building. Studies have found that administering ornithine naturally increases the release of human growth hormone (HGH) in animal and human studies. However, an increase in HGH in humans seems to occur with higher doses of ornithine.
