Vitamin C (ascorbic acid) crystals imaged by cross polarised light microscopy. Vitamin C is an antioxidant and is important for collagen formation and wound healing. A good source of vitamin C is found in a variety of fruit and vegetables including citrus friuts, brussels sprouts and broccoli. It is a water soluble vitamin that cannot be stored in the body so needs to be ingested regularly. A lack of Vitamin C causes scurvy. 100X image magnification.
