Vitamin B6, also known as pyridoxine, has several important functions in the body, including:
Protein metabolism: Vitamin B6 helps the body make and break down proteins.
Red blood cell formation: Vitamin B6 plays a role in the production of haemoglobin, a protein that carries oxygen in red blood cells.
Nervous system function: Vitamin B6 is involved in the production of neurotransmitters, chemicals that transmit signals in the brain and nervous system.
Immune system function: Vitamin B6 helps the body produce cytokines, which are involved in the immune response.
Hormone regulation: Vitamin B6 helps the body produce hormones, including serotonin, which regulates mood, and melatonin, which regulates sleep.
Eye health: Vitamin B6 helps the body produce melatonin, which may be important for eye health and the prevention of certain types of cataracts.
Overall, vitamin B6 is an important nutrient that is necessary for a variety of functions in the body. Adequate intake of vitamin B6 can help support overall health and wellness.
