The demands of our busy lives can lead us to neglect our own health and, over time, result in reduced energy, mood, and immunity, thereby “aging” us more quickly. Vitamin C is one of the best-researched nutrients and a key factor in healthy aging. It is essential for the functioning of the immune system, the growth and repair of body tissues, and to maintain the integrity of bones, gums, and teeth. Vitamin C is also among the most potent antioxidants, slowing down and preventing cell damage and the aging processes in the body.

In addition to vitamin C, there are multiple nutrients that the body needs every day to function at its best, including B vitamins and minerals. Electrolytes such as sodium, potassium, calcium, and magnesium are minerals essential for rehydration and energy production as well as cardiovascular, muscle, and nervous system functions. Sisu Ester-C® Energy BoostTM combines all of these important nutrients in a convenient drink mix to help keep active, busy people feeling their best and performing at their peak even on the busiest days.
