Oasis Vita-Drops for guinea pigs are a convenient way to assure your guinea pigs (also known as cavies) are receiving their daily intake of vitamin C. Guinea pigs, like humans, cannot manufacture their own vitamin C internally and must consume a fresh supply daily. Consumption of vitamin C each and every day is vital to promote normal growth and development and prevent the disease known as scurvy. This water soluble vitamin concentrate provides the 25 mg that all guinea pigs need daily to prevent scurvy. Oasis Vita-Drops Pure Vitamin C is formulated using the highest quality stabilized vitamin C possible, and is based on a 25 mg daily dose.
