Vitamin B-12 status did not change significantly after treatment in the placebo group with daily supplementation with high doses of oral vitamin B-12 alone or in combination with folic acid.

Oral vitamin B-12 supplementation corrected mild vitamin B-12 deficiency.

Vitamin B-12 + folic acid supplementation increased red blood cell folate concentrations and decreased total homocysteine concentrations by 36%.

Improvement in memory function was greater in the placebo group than in the group who received vitamin B-12 alone. Neither supplementation with vitamin B-12 alone nor that in combination with folic acid was accompanied by any improvement in other cognitive domains.

Vitamin B9 Folic Acid

Vitamin B9, also called folate or folic acid, is one of 8 B vitamins.

  • Folic acid is the synthetic form of B9, found in supplements and fortified foods.
  • Folate occurs naturally in foods.

Folic acid is crucial for proper brain function and plays an important role in mental and emotional health. It aids in the production of DNA and RNA, the body's genetic material, and is especially important when cells and tissues are growing rapidly, such as in infancy, adolescence, and pregnancy.

Folic acid also works closely with vitamin B12 to help make red blood cells and help iron work properly in the body.

Rich sources of folate include: spinach, dark leafy greens, asparagus, mustard greens, brussels sprouts, beans, soybeans, root vegetables, whole grains, oranges, avocado.
