CLEARDROPS® is a transparent liquid. The vitamin C is in excess within CLEARDROPS® . For this reason, in the sealed bottle, overtime, a light yellowish tint may be present but the liquid will be transparent. This is normal and does not affect the overall quality and effectiveness of the product. CLEARDROPS® is preserved with potassium sorbate. Due to the presence of the preservative potassium sorbate, a “fruity” odor and taste may be noticed.
