B12 Folic™

What Is B12 Folic™?

B12 Folic™ is a combination of two water-soluble B vitamins, folic acid and vitamin B12. These two vitamins are interrelated in function. They convert carbohydrates into energy and are vital in the metabolism of fats and protein. They play an important role in the maintenance of muscle tone in the GI tract, the functioning of the nervous system, and the integrity of skin, hair, and the liver. Folic acid is essential for normal fetal neural development. The B12 in this formula is provided as methylcobalamin, the most bioavailable form of this vitamin, as it does not require intrinsic factor for absorption.*†

Uses For B12 Folic™

Healthy Fetal Neural Development:

Folic acid is an integral factor involved in the formation of nucleic acids and the production of healthy DNA and chromosomes. In particular, this B vitamin is critical for the proper neural and cellular development of the fetal central nervous system. Folic acid promotes healthy cellular differentiation during the formation of the brain and spinal cord, helping to prevent neural tube defects. Additionally, folic acid is important for the growth and reproduction of red and white blood cells.*†  

Nervous System Health:

In recent studies, methylcobalamin has demonstrated an enhanced ability to support neurological function. Vitamin B12 promotes protein synthesis for maintaining healthy nerve cells and myelin. Methylcobalamin may also help to moderate levels of glutamate in the brain, encouraging healthy brain cell activity, as well as memory, mood, and cognitive function. In general, vitamin B12 works with folate to promote DNA and red blood cell health.*

Source for B12 Folic™

Folic acid is synthetically produced. Methylcobalamin is produced from corn dextrose fermentation. Hypo-allergenic plant fiber is derived from pine cellulose. Vitamin C (ascorbyl palmitate) is derived from corn dextrose fermentation and palm oil.
