As well as being used for its medicinal properties, turmeric has also been used for centuries as a natural dye. It is normal for the inside of the bottle to become stained by the yellow-gold pigment of turmeric, as well as transferring to your hands as you take the gummies. We recommend washing your hands after handling these gummies to preserve your clothes and surroundings! Any light dyeing of your fingertips or hands will fade with hand-washing.
