SINUS SUPPORT

---

Dr. Freire's Sinus Support supplies a synergistic combination of micronutrients, bioflavonoids, enzymes, amino acids and herbs that provide multi-faceted support for immune function and respiratory health. This formula provides natural support and quick relief for discomfort associated with immune hypersensitivity and histamine release, including watery, itchy eyes, sneezing, runny nose and nasal congestion.

Quercetin, a powerful natural bioflavonoid with strong antioxidant activity, and vitamin C are beneficial for respiratory health. They provide support for stabilizing mast cells that store and release histamine and moderate an exaggerated immune response to allergens. Quercetin inhibits inflammatory enzymes and increases mucus secretion from gastric cells. Vitamin C has been widely studied and is commonly known for its supportive role in moderating the severity or duration of acute immune challenges. This nutrient appears to heighten the immune response, impacting T-cell proliferation. Vitamin C also synergistically improves the ability of quercetin to preserve and increase glutathione levels, supporting reduced oxidative damage. Increasing this potent antioxidant may help reduce nasal obstruction, rhinorrhea and ear fullness.

Bromelain, a proteolytic enzyme purified from pineapple, is a supportive nutrient in helping prevent allergens from crossing the gastrointestinal tract. With the assistance of quercetin and vitamin C, bromelain inhibits the absorption of substances into the body that may induce the allergic response. Bromelain supports normal inflammatory response by hindering the body's production of kinins and fibrin. This natural enzyme contains constituents that help maintain a healthy cytokine balance. Bromelain has also been found to enhance the absorption of quercetin.

Stinging nettle, an herb named for the fine hairs found along its stems and leaves that break off when touched, has been used as a medicinal plant for centuries. Among other things, nettle roots or leaves were traditionally used as support for healthy breathing, throat discomfort and as an expectorant. Nettle's aerial parts may reduce the amount of histamine that is produced in response to an allergen. Stinging nettle leaf has been shown in vitro to inhibit the pro-inflammatory pathways related to allergic rhinitis. Nettle polysaccharides appear to stimulate tumor necrosis factor and T-lymphocyte activity, aiding immune system response.

N-acetyl-l-cysteine (NAC) is an amino acid precursor to one of the most important antioxidants in the body, glutathione. Both glutathione and NAC help reduce the viscosity of the mucus allowing for clearing of the airways and improved respiratory health. By disrupting disulfide bonds as a result of its sulfur content, NAC naturally thins mucus, which commonly thickens with hyperimmune response. Thinner mucus, along with trapped unwanted particles, can be more easily expelled from the lungs. 

The complementary combination of natural ingredients in Sinus Support have been formulated to assist the body in moderating unpleasant immune reactions and support healthy respiration.
