Vitamin B6, also known as pyridoxine, is an essential coenzyme required for protein, fat, and carbohydrate metabolism. Vitamin B6 is associated with reduced C-reactive protein levels, which is a marker of inflammation in the body. Studies suggest that B6 may help with premenstrual syndrome (PMS) symptoms like breast pain, bloating, depression, and anxiety. B6 is involved in producing “feel good” neurotransmitters dopamine and serotonin and prostaglandins, which control inflammation and blood flow. Vitamin B6 can also help treat morning sickness.*
