Elderberry Plus Immune provides immune support in a pleasant-tasting liquid.* Research suggests that certain herbs, mushrooms, and other natural compounds may have the ability to support normal immune functions, such as natural killer (NK) cell activity, cytokine synthesis, and the T-cell— and B-cell—mediated responses.* Ingredients, such as elderberry, shiitake, and wild cherry bark, are known for their beneficial effects for maintaining a healthy immune system.* Elderberry Plus Immune is sweetened with glycerine, tastes great, and is ideal for both children and adults.
