B?Complex SAP�is a sophisticated combination of essential B vitamins designed to increase energy production and support cardiovascular health. B vitamins are water-based coenzymes that assist the process of energy production throughout the entire body, and help maintain healthy skin, hair, eyes, liver, mouth, muscle tone, and the gastrointestinal tract. They are called B?complex because they complement each other and are only found in food or living tissues as a group. Most importantly, B vitamins work together to promote healthy stress levels and the proper functioning of the nervous system.
