Blue dye stains teeth and tongue for hours
I’ve found that BlueChew Gold tablets deliver intended medical results but the tablets contain dark blue dye that stains my tongue and teeth, leaving a highly noticeable blue discoloration that lasts approximately 12 hours even after vigorous brushing. Quite abad side effect for something meant for use prior to close intimate contact. I would strongly encourage BlueChew to offer a dye-free version or reformulate the tablets to eliminate this problem. Until then, buyers should be aware that the blue coloring may remain visible for many hours after taking a tablet.
