Child's sleep improvement
11 people found this helpful
I administer it to my child as prescribed by a geneticist. Given with water before bed, I've observed a considerable improvement in his sleep quality, and the unpleasant sour smell of sweat that used to arise while falling asleep has disappeared entirely following the intake.

Best sleep aid
10 people found this helpful
Based on reviews, I purchased this product in hopes it would help me sleep. After trying many herbal sleep formulations without success, I was blown away after taking four capsules the first night and sleeping soundly through the night. Now, three months in, I rarely experience sleepless nights. This is the best sleep aid I’ve come across.

L-Ornithine is fantastic for deep sleep. I take it alongside L-Tryptophan, magnesium, and B6, and it works wonders for me. I will continue purchasing this product from iHerb.

Rotational use

I sleep well when I take this before bed with Lysine. However, it’s important to rotate it with other supplements to maintain its effectiveness; continuous use might diminish the results.

Facilitates restful sleep

Great for sleep! I have Chronic Fatigue Syndrome, and this has really helped me sleep alongside other aids. My doctor confirmed through a urine test that it effectively removes ammonia from my system. I take one or two at night, and it significantly aids my rest.
