The recommended dose of fructase is 1-3 capsules. We recommend starting with the highest dose, to see how you react, and then tapering down to a smaller dose next time. You can do this until you can see the minimum dose your body needs to avoid triggering the symptoms of your food intolerance. Of course, what you eat/drink and portion size will matter (as will the severity of your intolerance), but the general rule is that by starting high, you can better tell if the product is helping you or not, rather than not being sure if it was enough. It is certainly helpful to taper the dose and see if you can go to a lower strength next time. Overdosing does not have any negative effect and is therefore not a bad thing. In some cases it is better to be on the safe side in order to avoid unnecessary complaints.
