Humans have two basic types of immunity: innate & adaptive.
Innate immunity launches an immediate, broad-spectrum attack against any immunity threat present. Adaptive immunity, on the other hand, takes longer to kick in and produces a specific response to a particular invasive agent.
It contains a highly purified form of beta-glucan, which research shows supports both innate and adaptive immune function. According to a clinical study, older adults (50-70 years old) taking Immunity Pro reported a 16% decrease in total upper respiratory tract infection (URTI) symptom days.
A 4-week clinical study demonstrated that stressed women taking Immunity Pro were 62% less likely to develop URTI than those taking a placebo.
