Additional Information

Connective tissue factors Potent nutrition support for skin, joints, vessels and discs

Connective tissues underlie the skin, and are the foundations for the joints, vertebral discs, walls of the blood vessels, bones and countless other supporting tissues. Cumulative damage to the body's connective tissues can markedly affect quality of life. The nutrients in this formulation are supportive to the enzyme pathways that renew connective tissues or nutritionally help protect connective tissues from degeneration due to environmental factors or intrinsic processes gone awry.

Store in a cool dry place.
