Immune Support

If you’re looking to support your body’s immune response – whether you’re feeling fine and want to stay that way, or you need to feel better quickly – trust Natural Factors’ products. Many supplements are formulated with our clinically proven ECHINAMIDE® echinacea, the result of many years of extensive research. We offer a range of single and combination formulas to support healthy immune function and respiratory health, relieve nasal congestion, and soothe sore throats.
