What is Thymic Protein A?

To put it simply, Thymic Protein A (TPA) is one of the most essential components of your immune system—helping in the formation and activation of your body’s T-cells.

Does my body create it naturally?

Fortunately, your thymus gland starts producing TPA even before you’re born. Unfortunately, however, your thymus begins shrinking after puberty, producing less Thymic Protein A as you age.

Why do I need ProBoost?

ProBoost exists to take over where your thymus gland stops—providing complete, fully-intact Thymic Protein A to help keep your immune system functioning properly.

Who should take ProBoost?

Anyone who is concerned about maintaining optimal immune system function will benefit from taking ProBoost Thymic Protein A.

How do you take ProBoost?

Take ProBoost sublingually (powder/tablets) for optimal absorption or as a capsule with water for intestinal absorption. Use 1-3 times daily or as directed by your healthcare practitioner.
