Missed sleep, chronic stress, and nutritional insufficiencies are all factors that may negatively affect immune function. Our Rapid Immune Support Protocol provides more targeted immune support in times of increased immune challenge.

Our Acute Immune Boost herbal and nutrient blend offers strong support for healthy immune function. Plan ahead to have a bottle of Acute Immune Boost on hand to be prepared for the first moment of significant challenge.

Our immune system has an immediate response to an immune challenge called the innate immune system. This system includes physical barriers like skin and mucosa, reflexes like the sneeze, cells protecting themselves by releasing immune chemicals, and immune cells such as Natural Killer Cells that can respond to immune challenges.

The other pathway of response, the adaptive immune response, takes a little more time but is more specific. It involves T and B lymphocyte cell response and, most importantly, antibody formation to the specific challenge presented.

Nutrient insufficiencies may lead to sluggish or reduced immune response. Our Rapid Immune Support Protocol includes nutrients and herbs in robust amounts to quickly nourish the effectiveness of both vital pathways of the immune response. Probiotics aid in assimilating nutrients and promoting effective gut barrier protection.

Lifestyle tip: limit sugar intake

Sugar is a known immune suppressor. Higher intakes of sugar can impact how your innate immune system responds when a threat is present. Sugar utilizes vital immune nutrients, such as vitamin C and vitamin D, leading to a lower available amount for immune support. It is important to avoid excess sugar intake especially during times of acute challenges.
