Vitamin B12 (cobalamin) is an essential nutrient for red blood cell production, DNA synthesis, and brain and spinal cord function. It must be obtained through animal products, nutritional yeast, or fortified foods.

Why is vitamin B12 important?
B12 is included in SiPhox Health's female Hormone+ panel due to its role in reproductive health and pregnancy.
