Ornithine, 500 Mg, 100 Capsules


The amino acid, l-ornithine, in powdered encapsulated form. Each bottle contains 100 capsules, with 500 mg. per capsule. Manufactured by the Dr Clark Research Association under their strict purity protocols.


Product Description

During cleansing, Dr. Hulda Clark recommended this supplement to break down and eliminate the ammonia usually released by microorganisms when they are killed and then accumulated in the liver. L-ornithine is a key compound for dispelling ammonia through the kidney-bladder system.*

What is it?

Ornithine, an amino acid manufactured by the body whenever arginine (also an amino acid), is metabolized, assists with the metabolism of nitrogen. Some studies indicate it naturally stimulates the release of growth hormones.*


Dr. Clark theorized that insomnia was mainly due to ammonia toxicity in the brain. An ornithine supplement can help eliminate the ammonia and assist with sleep. Unlike many sleep aids, this one can be taken continuously without harmful effects or addiction.*
