🧪 Formulation Notes

NOW Mushroom Immune Renew has been specifically formulated to support the immune system with standardized astragalus extract and a specialized mushroom and mycelial biomass blend. Our blend 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.
