Biotin aids in the metabolism of proteins and carbohydrates.*For over 60 years, Douglas Laboratories has been dedicated to meeting the needs of healthcare professionals and is recognized as a leader in the development of high quality, science-based, innovative nutritional supplements across 12 health functions that support healthy lifestyles.

Review: Excellent B complex - All I know is I always feel better emotionally, more alert, and calmer when I take it.
Review: Works for people with the MTHFR Gene. - I take this vitamin because I have the MTHFR gene, so I do not process regular folic acid. Works great.
