• 4Life Transfer Factor Blend educates and enhances immune system function. Recent independent laboratory studies show that 4Life Transfer Factor^® Tri-Factor^® Formula bolsters Natural Killer (NK) cell activity in the presence of a health threat, while activating a variety of other immune system cells, such as B cells and T cells.^† 4Life Transfer Factor has also been clinically proven to activate the immune system within 2 hours.¹ *
• Vitamin C is a potent antioxidant that has been shown to regenerate other antioxidants. Vitamin C also supports the immune system, including NK cell activity. This vitamin is also involved in collagen synthesis.*
• Zinc is an essential mineral for development, growth, and function of immune system cells like NK cells, T cells, and B cells, which are all important for healthy immune system function.*
• Vitamin K2 is essential for blood clotting and proper blood, bone, and kidney function. Vitamin K2 also supports protein synthesis. The form of vitamin K2 in Immune Boost is a very bioavailable form, which means it is easy for your body to use.*
• Electrolytes are important for rehydration, especially during physical stress or activity.*
• Vitamin D is essential for immune system health, and you can only get it through your diet, supplements, or spending time in the sun. Vitamin D also supports bone health. Each serving of Immune Boost provides 250% of your DV serving of vitamin D.*
