Deficiences of vitamin B6, a water soluble vitamin, are extremely
common. Studies have indicated that adequate intake of vitamin B6 can
reduce the risk of coronary heart disease. It can reduce the levels
of homocysteine as well, which is associated with an increased risk
of heart disease. Vitamin B6 has been shown to significantly reduce
the symptoms associated with morning sickness.
