The vitaminc C I'm using is granular like sugar and I'm currently storing it in a ziplock baggie in dark place. How do I know if it still any good or not? It is still just as white as the day that I bought it.

You don't know for sure because the first step of ascorbic acid oxidation is also white. That said, ascorbic acid is relatively stable when completely dry, so if the humidity in hour home is low, there is better chance it is still good.

Yes, there is such a thing as vitamin D toxicity - at high doses.

Vitamin C, also known as ascorbic acid, is necessary for the growth, development and repair of all body tissues. It's involved in many body functions, including formation of collagen, absorption of iron, the proper functioning of the immune system, wound healing, and the maintenance of cartilage, bones, and teeth
