How long you need to take Transfer Factor for Immunity Enhancement is mainly related to the patient’s physical condition, the severity of the disease and the response to treatment, etc. It should be analyzed on a case-by-case basis and cannot be generalized. Generally, 1 month is a course of treatment. Take it for at least 3 months. Transfer Factor is an immune booster and is mainly used for the treatment of chronically immunocompromised people, cancer patients, and people with viral infections that are difficult to treat with antibiotics. For patients with more serious conditions, transfer factor is often required under the guidance of a doctor. Since it takes a long time for the efficacy of transfer factor to take effect, it takes about 1-3 months to take it, depending on the individual. For adolescents with weak resistance and susceptibility to disease, transfer factor can also improve immunity, but when taking it, the dosage should be controlled and it is recommended to take it according to the doctor’s prescription. Long-term use of Transfer Factor can cause immune dysregulation, so patients should be careful not to take it for a long time or in large quantities for life.
