Kirkland Signature Vitamin C 1000mg, 500 Tablets is a high potency, nutritional supplement. In addition to Vitamin C, our product also contains a citrus complex of bioflavonoids, which may assist in the body's absorption of Vitamin C, and rose hips, which are a natural source of Vitamin C. We've added an easy to swallow, plant based coating to this essential daily vitamin that has many important functions in the body.
Is this vitamin C any good?. It is my understanding that many companies use crappy versions of Vitamin C.
