ProBoost Thymic Protein A is scientifically-proven immune system support.

ProBoost’s active ingredient, Thymic Protein A, has the same biological activity as a key, natural, thymic protein in your body. Unfortunately, our immune systems age just like the rest of us. Over time, the thymus gland atrophies and produces lower levels of the critical thymic proteins required for your immune system to mount an effective immune response.

ProBoost was developed to step into this gap—meeting the thymus shortfall, delivering natural support to your immune system and helping to jumpstart an optimal immune response. Thymic Protein A has shown, in scientific studies, to provide significant benefits in supporting and strengthening the immune system. These benefits include:

increase white blood cells

Increase White Blood-Cell Counts

Think of white blood cells as your immunity cells. In a sense, they are always at ready to fight. When your body is in distress, white blood cells rush in to help.

increase t-cell levels

Increase T-Cell (Helper Cell) Levels

Helper T cells are arguably the most important cells in adaptive immunity, as they are required for almost all adaptive immune responses.

induce apoptosis

Induce Apoptosis (Cell Death)

Apoptosis plays a crucial role in developing and maintaining the health of the body by eliminating old cells, unnecessary cells, and unhealthy cells.
