MANNOSIO 14 SACHETS Natural relief for urinary tract inflammations. Mannosio sachets, thanks to the extracts of Bearberry, Cranberry, Grapefruit, and Mannose, is the ideal supplement for the treatment of urinary tract infections. Warning: Grapefruit has been shown to have the ability to interfere with certain types of medications (including birth control pills and cholesterol-lowering drugs), and it may take very little, such as a juice plus a whole fruit, to decrease the absorption of medications with dangerous health risks. Do not use during pregnancy.
