Dr. Berg Chewable Vitamin C Complex is a premium-quality source of vitamin C. Each serving contains 200 mg of vitamin C and a proprietary blend of four organic nutrient-rich berries: acerola cherry, acai, blueberry, and strawberry. Because vitamin C can quickly degrade when exposed to heat, we use a unique freeze-drying technique that preserves nutrients and ensures that Dr. Berg Chewable Vitamin C Complex delivers high-quality vitamin C that won’t lose its nutritional value.  Most people struggle to swallow oversized vitamin C capsules. You told us, and we listened! That’s why we designed a delicious berry-flavored chewable that’s a convenient source of premium-quality vitamin C.
