Silver Lining Be Well Immune Support Capsules feature a synergistic blend of eight powerful ingredients in a single dose, maximizing both time and cost (buying separately would nearly double the expense). This unique formulation includes 250 mg of Quercetin, 150 mg of NAC, 650 mg of European Elderberry, 25 mg of Olive leaf, 150 mg of Pine Bark Extract, 10 mg of Zinc Citrate, and 500 IU of Vitamin D3, creating a significantly enhanced synergistic effect. These ingredients work together to support immune function and have been traditionally used in Herbal Medicine to alleviate symptoms related to colds and flu. Additionally, they offer further benefits such as anti-aging effects, improved cognitive performance, better respiratory health, and stronger teeth, bones, and hair. [VCAPS]
