Quercetin with Bromelain: Immune Support, Natural Anti-inflammatory and Respiratory Health - Advanced Synergy For Vitality and Cellular Protection

Quercetin with Bromelain, Nutricost is an advanced dietary supplement formulated to support immunity, combat inflammation and support respiratory system health. The product contains 880 mg of quercetin (in the form of quercetin dihydrate extracted from flower buds of Sophora japonica) and 165 mg of bromelain (proteolytic enzyme extracted from pineapple stem, standardized to 395 GDU). This synergistic combination merges the antioxidant, antihistamine and anti-inflammatory effects of quercetin with the digestive, anti-inflammatory and absorption-supporting action of bromelain.

Quercetin is a natural flavonoid found in numerous fruits and vegetables, known for its antioxidant and immunomodulatory properties, while bromelain is an enzyme with systemic and local action, which improves the bioavailability of quercetin and contributes to reducing inflammation. Together, these two ingredients create a powerful supplement intended for people seeking immune system support, respiratory health and a healthy inflammatory response.

 

Detailed Benefits of Quercetin with Bromelain

 

• Advanced support for the immune system

One of the most important functions of quercetin is supporting natural immunity by regulating the body's inflammatory and oxidative responses. This flavonoid acts as an immunomodulator, supporting the balance between activation and calming of the immune response in the face of external stressors, viral or bacterial infections.

Quercetin:

✓ Helps regulate the activity of immune cells (lymphocytes, macrophages)
✓ Reduces the release of histamine and inflammatory cytokines
✓ Supports the body's oxidative balance, limiting cellular damage

Bromelain contributes to these effects by:

✓ Improving the absorption of quercetin at the intestinal level
✓ Supporting blood circulation and lymphatic drainage
✓ Reducing edema and inflammation associated with infections

This combination makes Quercetin with Bromelain particularly useful during periods of increased immune demand, such as the cold season, exposure to allergens, or during post-viral recovery.

 

• Natural antihistamine effect and control of seasonal allergies

Quercetin is recognized for its ability to inhibit histamine release from mast cells - a key mechanism in allergic reactions. Through this action, it helps:

✓ Reducing nasal congestion, sneezing, and eye irritation
✓ Controlling upper respiratory tract inflammation
✓ Improving breathing quality and comfort during allergy season

Bromelain has an adjuvant role in reducing allergic symptoms by:

✓ Breaking down excess mucus in the airways
✓ Supporting sinus function and reducing mucosal inflammation
✓ Enhancing the anti-inflammatory action of quercetin

For people suffering from seasonal allergies or inflammatory reactions to pollen, dust, or other environmental allergens, Quercetin with Bromelain offers a natural alternative to classic antihistamines, without sedative side effects.

 

• Antioxidant protection and support for cellular health

Oxidative stress is one of the major causes of premature aging and cellular deterioration. Quercetin, through its flavonoid structure, is a powerful antioxidant that neutralizes free radicals and prevents damage to cellular lipids, proteins, and DNA.

Among the antioxidant benefits are:

✓ Protecting cells against oxidative stress induced by toxins, radiation, or pollution
✓ Supporting cardiovascular health and vascular endothelium
✓ Preventing chronic inflammation and associated degenerative diseases

Bromelain enhances these effects by:

✓ Decreasing the level of prostaglandins and bradykinin (inflammatory factors)
✓ Supporting systemic detoxification processes and tissue healing
✓ Improving circulation, facilitating the transport of nutrients and oxygen

This cellular protection has important implications not only in preventing chronic diseases but also in maintaining daily health, vitality, and the regenerative capacity of the body.

 

• Respiratory health and optimal lung function

Quercetin and bromelain have been studied for their role in supporting respiratory tract health, especially in contexts of inflammation, allergies, or viral infections. Quercetin reduces inflammation and hyperreactivity of the airways, while bromelain helps thin mucus and support lung function.

Through these mechanisms, the product:

✓ Improves breathing and lung capacity
✓ Reduces respiratory discomfort, congestion, and cough
✓ Supports recovery after respiratory or viral infections

It is an excellent choice for people suffering from recurrent sinusitis, asthma, allergic rhinitis, or other inflammatory respiratory conditions.

 

• Systemic anti-inflammatory support

Chronic inflammation is involved in numerous modern conditions: autoimmune diseases, arthritis, cardiovascular, metabolic, or neurological disorders. Both quercetin and bromelain are natural anti-inflammatory agents, capable of modulating the inflammatory response without negatively affecting the gastric mucosa or liver, as happens with classic anti-inflammatories.

Anti-inflammatory effects include:

✓ Decreasing edema and pain in joint conditions (arthritis, bursitis)
✓ Reducing muscle inflammation and accelerating post-workout recovery
✓ Supporting mobility and physical comfort

By combining the two substances, Quercetin with Bromelain offers an efficient and well-tolerated solution for people facing chronic pain or inflammation.

 

• Cardiovascular health and vascular protection

Quercetin is also known for its beneficial effects on the cardiovascular system. It helps with:

✓ Reducing blood pressure by relaxing blood vessels
✓ Improving vascular elasticity and blood flow
✓ Preventing oxidation of LDL cholesterol and formation of atheroma plaques

Bromelain contributes to cardiovascular health by:

✓ Antiplatelet effect - reduces the risk of excessive coagulation
✓ Supporting blood fluidity and tissue oxygenation
✓ Reducing inflammation in blood vessels

Together, these effects support the prevention of cardiovascular diseases and the maintenance of a healthy circulatory system.

 

• Unique synergy for high absorption and efficiency

One of the challenges of using quercetin is reduced absorption at the intestinal level. Studies show that bromelain not only has its own powerful effects but also significantly improves the bioavailability of quercetin. This synergy leads to:

✓ Increased efficiency in smaller doses
✓ Faster and more durable action in the body
✓ More intense response of the body to inflammation, allergies, or oxidative stress

This Nutricost formula is specially designed to maximize the effects of each ingredient and to provide complete, safe, and efficient support for general health.
