Curcumin supplements are considered generally safe and no studies have confirmed side effects at appropriate doses. It is assumed that regular consumption of about 1 gram of curcumin per day does not cause any side effects. However, some people may experience some discomfort, which may be evidence of the strong immune-stimulating effect of curcumin. Such temporary discomforts can be called side effects.
When using natural curcumin therapy, it is worth following the procedures recommended in traditional methods of treatment. According to the knowledge of Indian and Chinese medicine, curcumin has benefits that are revealed during long-term and systematic supplementation. Therefore, a person experiencing any discomfort or recurrence of old ailments should temporarily reduce the dose of curcumin taken, and then – after these symptoms have subsided – return to the recommended amount.
During curcumin supplementation, discomfort may appear in the weakest areas of the body. Some people experience mild digestive problems. This may include mild pain, diarrhea or constipation. Others may experience headaches or nausea. They may also experience skin rashes or itching in certain areas of the body.
There are currently no scientific studies to support the existence of curcumin side effects. There is also a lack of studies to support the beneficial effects of curcumin and to provide specific doses for specific conditions.
