High Strength Vitamin B6 - Improve Mood, Behaviour, Sleep Patterns and PMS! Vitamin B6, also known as pyridoxine is one of the major members of the B Complex family of vitamins. Being water-soluble vitamin B6 must be replenished on a regular basis. It's prime role is to process amino acids, the building blocks of protein and some hormones, such as seratonin, melatonin, and dopamine. The effects of these hormones on the body can be quite significant. Seratonin, a brain chemical can have a really positive effect on mood, behaviour, including ADD (Attention Deficit Disorder) and ADHD (Attention Deficit Hyperactivity Disorder), improve sleep patterns and in many cases has an anti-depressant effect. A minimum of 40mg of B6 daily can help to relieve the symptoms of PMS (PreMenstrual Syndrome), such as depression, irritability and tiredness, as well as help reduce homocysteine levels, preventing heart disease symptoms, acne, mouth ulcers and some women find it effective in reducing morning sickness. B6 is a vitamin everyone should get enough of!
