Do I have to limit eating blueberries or blackcurrants by taking Ovulan?

There is no information that it is necessary to limit the eating of blueberries or black currants when using Ovulan. Such an interaction is not described. A normal, varied, rational diet in terms of quantity and quality of products does not pose a threat to the effects of contraception. You can eat fruit remembering not to provoke diarrhea or vomiting by eating, for example, stale fruit. If gastric ailments appear in you as a result of consuming a large amount of fruit, then in this case it may be advisable to limit their amount.
