AdrenalCore is a 2:1 ratio of Vitamin C to bioflavanoids helpful for nourishing the adrenal glands. Vitamin C plays a significant role in improving adrenal health. Excessive cortisol excretion can be suppressed by vitamin C supplementation. Vitamin C is also critical for adrenal function. Your body's highest levels of vitamin C are found in the adrenal glands and brain tissues, and the urinary excretion of vitamin C is increased during stress. Vitamin C also acts as a mast cell inhibitor and can help to reduce histamine when it is excreting in excess. Excessive histamine can cause an elevation in anxiety and restlessness.* DO NOT CONTAIN: Wheat, gluten, corn protein, yeast, soy, animal or dairy products, fish, shellfish, peanuts, tree nuts, egg, artificial colors, artificial sweeteners, or preservatives.
