A unique chemical complex to Chlorella protein called CGF (Chlorella Growth Factor) is believed to be the core of it's healing properties. All elements within Chlorella's nucleus (peptides, proteins, the nucleic acids (RNA and DNA), polysaccharides, beta glucans, sulfur and manganese combine to form CGF. It is found only in the nucleus of the cell.
Researchers have discovered that CGF is produced by Chlorella during the intense photosynthesis that enables Chlorella to grow so fast. Each cell multiplies into four new cells every 20-24 hours, and CGF promotes this rapid rate of reproduction.
This growth factor helps the growth of animals, microorganisms and renews our cells. Experiments with microorganisms, animals and children have shown that CGF promotes faster than normal growth without adverse side effects, and in adults, it appears to enhance RNA/DNA functions responsible for production of proteins, enzymes and energy at the cellular level, stimulating tissue repair and protecting cells against some toxic substances.
In children and adults CGF repairs damaged tissue and protects cells from toxins. CGF also helps promote the growth of beneficial bacteria in the colon.
CGF does not stimulate growth or weight gain in adults, nor is it known to stimulate the growth rate of any disease. It only stimulates growth in children and animals who have not yet reached their full, adult size. These results (increased selective growth and healing) cannot be explained by any other component in Chlorella other than its unique CGF.
Perhaps among the most interesting CGF research was done at a hospital where patients with long-standing wounds (gastric and peptic ulcers, and chronic gastritis) that refused to heal after treatment with standard medications. In these patients given liquid CGF in a matter of days, new tissue began to appear and all were soon healed completely. This clearly showed that CGF was capable of stimulating tissue repair when the body's healing sources were exhausted.
Dr. Bernard Jenson wrote in his book, Chlorella: Gem of the Orient, that CGF and the nucleic acids are the most valuable features of Chlorella because "they lift the energy level of the body as a whole and because they repair and renew all organs, glands, and tissues of the body."
The level of CGF in Chlorella supplements varies. While whole Chlorella typically contains about 5% CGF, liquid concentrates and powdered CGF extracts may contain 10-15 times this amount. Some special strains of Chlorella can exceed 20% CGF. The higher the level of CGF, the great the benefits.
