Immune Health

Your body’s natural defense system is an intricate network of cells, tissues, and organs that band together to defend you against a host of invading microorganisms, including bacteria, viruses, parasites, fungi, and all manner of allergens. And it works great for the most part—until stress, lack of sleep, age, physical inactivity, or questionable lifestyle choices drag it down. To help keep your immune system in top form, Doctor’s Best provides natural immune enhancers extracted from medicinal plants, including mushrooms, brown algae, noni fruit, and artemisia, as well as enzymes, amino acids, and vitamins that promote immune response and regulate immune system function.*
