If you are experiencing any side-effects from using our products such a runny nose, tiredness, nausea, muscle aches or any other type of detox symptoms, please stop using the products for 3 days or until symptoms subside, and then continue use as normal. Although rare, detox-like symptoms are sometimes experienced in the first few days of supplementing GcMAF as the immune system adjusts. These may cause some discomfort but are not harmful. If you are concerned in any way please consult your doctor.
