Ornithine is a non-essential amino acid that plays a central role in the urea cycle, functioning along with Arginine and Citrulline to rid the body of ammonia, a byproduct of protein metabolism. Because Ornithine is converted into Arginine, it can help maintain healthy Arginine levels in the body. Ornithine can also be converted into other amino acids, such as citrulline, proline, and glutamate, as well as creatine, an important muscular energy source.

L ornithine

I use this to get easier asleep, it helps! I take 4 pills before bedtime and go to sleep easily. When i wake up during thd night I usually take 2 more and go back to sleep. I suffer from fatigue syndrome and it helps me a lot.

Kicked back on me ...

Posted by StarFire on Sep 19, 2015

Seemed to work for a short while for longer/better sleep. Then I started getting very fatigued... "Theoretically should reduce ammonia, but has oddly been noted to both increase and decrease ammonia concentrations. Requires more studies to investigate this topic" (From Examine Com) I took 1g of ALCAR (which is a very good quick ammonia reducer) and my fatigue and brain fog went away in rapidly!
