Doctor’s Best harnesses the natural powers of Vitamin C in the unique Sustained Release PureWay-C supplement to provide you with maximum, long lasting nutritional support. Each daily serving provides optimal support for your full body health and immune strength. Vitamin C is essential for your overall health, providing a plethora of benefits with each serving. Vitamin C supports healthy immune systems, helps reduce the likelihood of illness, promotes healthy cardiovascular function, improves iron absorption, and provides antioxidant protection. This powerful nutrient helps increase the white blood cell production of lymphocytes and phagocytes, which play a crucial role in protecting the body from illness and infection. The benefits of each daily serving are further advanced through the addition of citrus bioflavonoids to increase bioavailability and absorption with each dose. Doctor’s Best uses vegan and vegetarian ingredients to create this Sustained Release Vitamin C formula, creating a safe addition with nearly any dietary restriction. Just one tablet a day is all you need for the ultimate source of immune support.
