An Overview of Vitamin B9

B9, or Folate, is a water-soluble vitamin found in legumes, whole grains, seeds, dark leafy greens and citrus fruits. Folic Acid is the synthetic form of Vitamin B9 that is found in nutritional products and fortified foods.

Vitamin B9 supplementation has been shown to provide positive support for:

  • Cognitive health
  • Nervous system function
  • Immune system response

Folate is an essential vitamin that the body is unable to produce on its own. Therefore, it must be replenished every day through the diet and/or supplementation. Folate deficiency may result in tiredness, fatigue and weakness, depressed mood and mental confusion.

Science and Pharmacology of Vitamin B9

B9, or Folate, is a cofactor. Cofactors are the most important components required to maintain fundamental processes throughout the body. Basic nervous system functions such as neurotransmitter synthesis and healthy cell-to-cell communication would not be possible without the presence of necessary vitamin, mineral and amino acid cofactors.

Supplementing a balanced diet with Vitamin B9 has been clinically shown to promote healthy neurological function. Because of its nutritional value, Folate is used in several Clarocet formulations along with other essential vitamins, minerals and amino acids that are associated with healthy nervous system function.
