Immune Support

Immune support starts with the basics of healthy living: eating whole foods, getting restorative sleep, stress management, maintaining a healthy mindset and reducing toxin exposure. In addition to the fundamentals, certain immune support supplements can be very helpful. Vitamin D, selenium, glutathione, zinc and vitamin A are all excellent immune support supplements. A healthy gut equals a healthy immune system because the majority of the immune system is located in the gut!  Probiotics can also help to support a healthy gut and immune response. Our most popular immune support supplements are Vitamin A Drops, Optimal Vitamin D3 Drops, Optimal Zinc Lozenges, Optimal Liposomal Vitamin C and ProBiota HistaminX.*
