The correct dosage of 0.1% Methylene Blue is in the range of 6 to 15 drops(in a solution of vitamin C) once or twice a day dependent on your size. You can take this dose twice a day, but you should never take it after about 3 pm because of its energizing effects.
You should always take MB with at least 1000 mgs of vitamin C in water in order to avoid its side effects -- Taken just on its own, MB turns your urine green and the whites of your eyes blue because it stains carbohydrates blue. Other than that there are no side effects. I've taken MB with Vit C for 8 years and what you will also find is that it will give you an energy boost and wake you up due to its positive methylation effects on the body.
You should never take MB in the evening otherwise you might have difficulty getting to sleep because it is so energizing. Other than that, I've found MB easy to use and very useful against pathogens.
The dosage that is advised here is relatively small and very safe. In the 1960s they used to give the US troops in Vietnam MB by the spoonful to help recover them from malaria.
