Cranberry capsules are not recommended for menstruation because they are a kind of health product and their specific ingredients are not known, so it is difficult to determine whether they will have adverse effects on menstruation, so they should be taken with caution. Cranberry, like grape seeds, has the effect of improving atherosclerosis, restoring blood vessel elasticity and promoting blood circulation, so non-menstruating women can take it reasonably according to their own situation. In addition, long-term use of cranberry capsules can also relieve urinary tract infections, gynecological inflammation, etc., but it should be noted that any health products only play a health and prevention role, not a therapeutic effect. Therefore, if you suffer from urinary tract infections or gynecological diseases, you must go to a regular hospital to seek medical treatment under the guidance of a specialist to avoid delaying the condition. In addition, diabetic patients, patients taking aspirin or warfarin are prohibited to take the capsules.
