People often take B vitamin supplements to support their cardiovascular health, metabolism and mood support. B vitamins are involved in the synthesis of important brain chemicals such as serotonin and dopamine. If the body is unable to produce these chemicals in adequate amounts, it could impede the quality of our daily lives. People who have dietary restrictions and/or are suffering from certain illnesses may have higher requirements for certain B vitamins. While there are B vitamins in many of the foods we eat, some people have difficulty absorbing them efficiently and/or may not be getting them in the proper balance. Having a high potency B vitamin supplement that contains all of the critical B vitamins in the proper proportion can be a convenient way to get these important nutrients. All Mason Natural products are produced in a GMP certified facility and laboratory tested for purity.
