Description
Vitamin B12 and folic acid, also known as vitamin B9, are both important B vitamins that work together in the body to support many functions, including:
- Red blood cell production: Both vitamins are essential for creating red blood cells.
- DNA and RNA production: These vitamins help the body produce the genetic material that builds cells.
- Nervous system health: Vitamin B12 is especially important for maintaining healthy nerve cells.
- Immune function and mood: Vitamin B12 and folic acid work together to produce S-adenosylmethionine (SAMe), which is involved in these areas.
A deficiency in either vitamin B12 or folic acid can cause a range of problems, including:
- Extreme tiredness
- Lack of energy
- Pins and needles
- Sore and red tongue
- Mouth ulcers
- Muscle weakness
- Disturbed vision
- Psychological problems, such as depression and confusion
- Memory, understanding, and judgment problems
Pregnant women who don't have enough vitamin B12 may increase the risk of their baby developing a neural tube defect.
Fasting not required.
