It is very helpful for sleeping after killing parasite!

I bought L-Ornithine for helping sleep during parasite cleanse which is part of Dr. Clark protocol. It converts brain ammonia which released from Parasite into urine acide and excreted through urine, so we could sleep. It is not habit forming, when parasite cleanse is done, I could stop it without any problem. If you struggle with sleep, you could try this product, if makes you sleep, it means you have parasites in your body and you need eradicate them, this is diagnostic use,

Good purchase

’ve been taking Nutricost L‑Ornithine 500 mg daily for about three weeks, and I’m genuinely impressed with the differences I’ve felt. First, my post-workout recovery feels noticeably improved—muscle soreness that usually lasts two days is now fading by the next morning, allowing me to train consistently. Second, I’ve experienced a welcome lift in daytime energy and alertness—no jitters, just steady, sustained focus, especially during late-afternoon slumps. Lastly, my nights feel calmer and more restful when I take it an hour before bed; I’m falling asleep more easily and waking up feeling refreshed instead of groggy. The capsules are easy to swallow, and I appreciate the no-nonsense formulation with a clean label. Overall, Nutricost L‑Ornithine has been a solid natural ally for energy, recovery, and a more balanced sleep routine—definitely worth trying if you want gentle yet tangible support in all three areas.

I take this supplement since it is improving quality of my sleep, it is deeper and more sound. Ornithine is also a good muscle support; and it eliminates harmful accumulated ammonia from the brain. As usual with Nutricost - a great balance between the price, quality and quantity. Warm recommendation.

Great

i take L-Ornithine because L-ornithine has been shown to reduce cortisol levels (a stress hormone) and alleviate fatigue by improving sleep quality and reducing stress responses. And L-ornithine increases the excretion of ammonia and helps regulate metabolism, which can improve athletic performance and reduce feelings of fatigue. I am using every day for stress reduction and better sleep.

Excellent

⭐⭐⭐⭐⭐ Great quality and exactly as described. The ingredients are clean and well selected, which makes the product feel safe and effective. The taste is good and easy to take, and the size is convenient for daily use. The package arrived well sealed and in perfect condition. I noticed clear benefits after regular use, with no side effects at all. iHerb always delivers reliable products, and this one did not disappoint. Definitely worth the price and I highly recommend it.

ornithine helps to calm down and sleep at night and works in metabolizing ammonia and urea which is a breakdown of protein metabolism the ingredients are clean and the dose is good per tablet

So far so good

I've decided to give this brand a try as the one I previously ordered from the Swanson range didn't quite sit that well with me somehow. This one so far seems to be working o.k. I take 1 at night before bed as I'm taking it for sleep only and so far no side effects. Tablets are a good size and easy to swallow.
