Bromelain Sinus Ease™


 

Nature's Life Sinus Products:


 

Sinus cavities are lined with delicate mucous membranes, which act as filters for your respiratory system. Normal sinuse tissues are pink and healthy. For many people, when their sinuses come in contact with allergens, pollutants or harmful micro-organisms, histamines are released as a protective measure by the immune system. Sinuses naturally respond by becoming irritated, red, and inflamed with these healing histamines. This process, called the natural inflammatory response, helps to neutralize and remove the irritants in sinuses cavities. Sometimes, however, the immune system continues to flood the sinuses even after the irritants are removed. Bromelain Sinus Ease™ contains three ingredients that have been shown to enhance the body’s ability to reduce this natural inflammatory response and help clear up sinuses.*

Bromelain

Bromelain is a group of protein-digesting enzymes extracted from pineapples (Ananassa sativa). Bromelain breaks down fibrin—a key component of the body’s natural inflammatory response to allergens and other foreign stimuli.* Bromelain also appears to inhibit the natural formation of prostaglandins (hormone-like substances) that trigger the natural inflammatory response.*1  It makes mucus less thick,2  allowing the mucus to drain more easily.*

Human trials have shown that by breaking down and helping to remove fibrin, bromelain reduces the discomfort of irritated tissues.*3   Double-blinded trials in patients with irritated sinuses show that the natural inflammatory response is reduced more effectively by concentrated bromelain than by placebo.*4 ,5 ,6 ,7  In all cases, a majority of people responded well to bromelain supplements.*

Bromelain has also helped reduce the dura­tion of the natural inflammatory response after nasal procedures by over 70% in a controlled trial.*8 

The recommended daily amount of Nature’s Life Sinus Ease™  utilizes 1,200 mg a very high potency bromelain enzyme which has an activity of 2,880 GDU (Gelatin Digestive Units), or 4,320 MCU (Milk Clotting Units) per serving.

Vitamin C

Vitamin C also helps reduce histamine release.*9   Some studies have reported that vitamin C is useful in reducing the natural inflammatory response in nasal passages.*10, 11, 12   The effectiveness of vitamin C in reducing histamine release is still debated, however, because a controlled trial was unable to show consistent effects.*13  Doses up to 2 grams per day have been used by researchers. It may be diffi­cult to show these effects in research trials because vitamin C appears to help only some people without affecting others.*14  Studies, however, clearly show that vitamin C supplementation can lower elevated blood levels of histamines.*15, 16 Nature’s Life adds naturally-buffered vitamin C to Sinus Ease due to its safety, immune-supporting effects and potential effica­cy to reduce histamine release.*

Quercetin is a bioflavonoid found in many natural foods including citrus fruits, onions, apples, tea and lettuce. As with bromelain, quercetin helps reduce the natural inflammatory response by inhibiting the natural formation of the pro-inflammatory agents, prostaglandins and leukotrienes (white blood cells).*17,18  Quercetin also helps lessen the natural inflammatory response for children with sensitivities to inhalants.*19  Additionally, quercetin may help reduce the effects of harmful micro-organisms *20  Bioflavonoids at doses of 1,200 mg per day have reduced the natural inflammatory response in human studies in combination with 1,200 mg vitamin C,21 an outcome con­firmed in double-blinded research using 600 mg/day of bioflavonoids and 450 mg/day of vitamin C.*22

Substances which inhibit the natural inflammatory response rarely target just one part of the body.* While quercetin has yet to be tested in reducing the natural inflammatory response in sinuses specifically, doctors of natural medicine frequently use it for that purpose because of its proven ability to lessen the natural inflammatory response elsewhere in the body.*

Nature’s Life Sinus Ease™

Nature’s Life has combined these powerful phytonutrients to make Sinus Ease™. High potency Bromelain, Quercetin and vitamin C work to inhibit the natural pro-inflammatory response and encourage adequate sinus drainage.* No safety concerns have been identified with any of these ingredients.23, 24  It is recommended to take the three capsules per day between meals. Since bromelain is a proteolytic enzyme, if taken with a meal it will act on the protein in the food rather than the natural pro-inflammatory fibrin, so remember to take it between meals.*  Enjoy the winter season and find relief from allergens throughout the year!  Nature’s Life Sinus Ease™ can help.
