How do the B vitamins in Cataplex G support health?

Cataplex G contains the important B vitamins riboflavin (B2), niacin (B3), and pyridoxine (B6). The members of the B-complex family of vitamins are responsible for many important physiological processes concerned with both mental health and physical well-being.*

Riboflavin contributes to the production of cellular energy, and niacin is a coenzyme essential for cell respiration, protein and carbohydrate metabolism, and lipid synthesis. Vitamin B6 is an essential nutrient comprised of six related compounds1 that support the healthy functioning of the nervous system,2 cellular metabolism,3 and immune system4 as well as formation of red blood cells. (A vitamin B6 compound, pyridoxal 5-phosphate, enables the first step in the synthesis of heme, the molecule that binds to oxygen in red blood cells.5) In addition, vitamin B6 is involved in the function of several essential chemical reactions in the body, including amino acid6 and red blood cell metabolism (due to heme synthesis).7 Vitamin B6 also is required for the synthesis of the nucleic acids RNA and DNA, molecules that carry genetic instructions for normal cellular growth and reproduction.*

How does Cataplex G provide antioxidant support?

Cataplex G provides a good source of antioxidant vitamin C and riboflavin. Riboflavin is required (in the flavin adenine dinucleotide coenzyme form) by an enzyme, glutathione reductase, that converts oxidized glutathione to the reduced form.8 Reduced glutathione acts as an antioxidant in various types of cells and protects the body against oxidative stress.9 Vitamin B6 may also be involved in the rate of glutathione synthesis in red blood cells, although the effects of vitamin B6 deficiency on the concentration of glutathione in red blood cells may vary from person to person.10*

Whole Food Nutrient Solutions

Since 1929, Standard Process has been the visionary leader in whole food nutrient solutions. We apply systems thinking to holistic nutrition that empowers practitioners to transform lives. Dedicated to the whole food philosophy of our founder, Dr. Royal Lee, our goal is to carry on his mission to provide nutrients for the body that are as close as possible to how they are found in nature.

Our products include foods that are prepared in a way that safeguards their nutritional value. The majority of these ingredients are grown locally on our certified organic farm and may require chopping, dicing, juicing, and/or drying for use in our products. The resulting whole food ingredients are then added to a formula that may include whole food extracts, animal tissue extracts and concentrates, botanicals, whole food isolates, and synthetic ingredients. These highly complex combinations contain a variety of elements designed to trigger trophic effects that support the body’s healthy balance and wellness.*


Suggested Use: One tablet per meal, or as directed.
