Depending on the brand, 50 ml of liquid stevia contains thousands of drops, as the dosage varies greatly. The bottle states that 2 drops are equivalent to the sweetening power of 5g of sugar; a 50ml bottle can last for up to 500 applications. Assuming that 1 application is 2 drops, a 50 ml bottle would contain about 1000 drops. As I have been using other products from Phytopharma for decades, I would like to mention here that I am very satisfied with Phytopharma overall.
