🧪 Formulation Notes

NKC+ delivers the natural nutrient profile found in genuine whole foods. NKC+ has been specifically formulated to support the immune system with standardized astragalus extract and a specialized mushroom blend. Our specialized blend of eight mushrooms has been optimized for the characteristic mushroom polysaccharides known as beta-glucans. Mushroom beta-glucans have been long respected and scientifically studied for their immune system supporting properties. Astragalus has been included to complement our mushroom blend due to its ability to support a healthy immune system response.

Natural color variation may occur in this product.
