We know how important your family’s health is to you — that’s why we made the C 1000+ Sustained Release. A powerful immune system is the cornerstone of staying healthy, so it’s important to provide your immune system with the nutrients it needs to stay strong. Vitamin C plays a key role in immune support, which is why we’ve packed each C 1000 + Sustained Release tablet with 1000 mg vitamin C. We’ve also added rose hips for an extra source of vitamin C, and bioflavonoids for antioxidant power. This supplement is formulated to release over a period of time, for consistent and extended immune support.
