ClearSleep® is a transparent liquid. The vitamin C is in excess in ClearSleep®, and for this reason, in the sealed or opened bottle overtime a light yellowish tint may be present. This is normal and does not affect the overall quality and effectiveness of ClearSleep®. Taste and smell may be different from individual to individual. As ClearSleep® is preserved with Potassium sorbate, some individuals notice an “fruity” odor and taste in ClearSleep®.
