How it works
The Quercetin-Bromelain Complex from Douglas Laboratories® is a powerful supplement designed to support overall health and wellness. This unique formulation combines three key ingredients—quercetin, buffered vitamin C (magnesium ascorbate), and bromelain—each carefully selected for their complementary health benefits. Together, these ingredients provide a potent antioxidant boost, enhanced immune support, and digestive aid.
Quercetin is a bioflavonoid known for its exceptional antioxidant properties. As a natural compound, it helps protect the body from oxidative stress and supports the immune system. By reducing free radicals, quercetin aids in maintaining healthy cells and tissues, making it an essential addition to your daily wellness routine. This bioflavonoid also has anti-inflammatory effects that can contribute to joint and overall tissue health.
The inclusion of buffered vitamin C in the form of magnesium ascorbate further enhances the antioxidant activity of quercetin. Vitamin C is vital for immune function, skin health, and tissue repair, and when paired with quercetin, it provides synergistic support to bolster the body’s natural defense mechanisms. The buffered form of magnesium ascorbate ensures better absorption and minimizes potential gastrointestinal irritation, making it a gentle yet effective choice.
Bromelain, a proteolytic enzyme derived from pineapple, adds an extra layer of support to this formula. It helps to break down proteins and may assist with digestive health by promoting proper digestion. Bromelain is also known for its anti-inflammatory benefits and its ability to improve nutrient absorption, allowing your body to maximize the effectiveness of the quercetin and vitamin C combination. Whether you’re looking to support your immune system, reduce inflammation, or promote digestive health, the Quercetin-Bromelain Complex is a versatile supplement that delivers multiple benefits for your body’s needs.
This combination of powerful antioxidants and enzymes makes the Quercetin-Bromelain Complex an ideal supplement for anyone looking to maintain optimal health and wellness. With its synergistic effects on immune function, inflammation reduction, and digestion, this supplement is an excellent choice for supporting your body’s natural processes every day.
