  • Who would benefit from Kaprex® Al?

    Health care professionals typically recommend this product for those who may benefit from support for balanced immune function.*

    How does Kaprex® Al work?

    It provides nutrients to support balanced immune function, including novel selective kinase response modulators (SKRMs) shown to favorably modulate eicosanoid formation in target cells without affecting related health-promoting activities. Balanced kinase (specialized enzyme) signaling helps to maintain healthy immune function, and SKRMs can enhance signals from a healthy diet.*

    How does Kaprex® Al compare with other products or approaches?

    This product contains only natural ingredients for a safer long-term approach, and has been clinically reviewed at the FMRC. This product gently targets underlying activities associated with minor pain and immune system function. It uniquely combines immuno-supportive nutrients with natural selective kinase response modulators (SKRMs) that demonstrate tissue-specific modulation of immune response activities, without interfering with healthy functioning. It also supplies vitamin D3 (cholecalciferol), the most bioavailable form of supplemental vitamin D.*

    How long is Kaprex® AI typically recommended?

    This formula was designed for strategic, long-term support for balanced immune function. Individual results and recommendations may vary based on your specific needs. For best results, follow your health care professional's guidelines.*
