Improve Your Respiratory Health with Respivits

Respivits is an innovative dietary supplement whose unique composition includes active ingredients carefully selected for their ability to enhance respiratory function and strengthen the body's natural defenses.

Respivits provides support for the upper respiratory tract, which is often exposed to allergens and environmental pollutants that can impair its function and overall health. During blooming periods or in polluted environments, the respiratory pathways can become irritated, leading to unpleasant reactions such as sneezing, a runny nose, and a feeling of congestion.

Our respiratory system is a first line of defense against external attacks. Keeping it healthy is crucial not only for breathing but also for overall immunity. A healthy respiratory tract more effectively filters and eliminates harmful particles and microorganisms, thereby reducing the risk of allergies. Respivits offers natural support with ingredients known for their effectiveness in enhancing resistance against environmental and seasonal aggressors.

Phytosome™ Technology: Optimization of Absorption and Solubility

  • The Phytosome™ technology, central to the formulation of Respivits, is an advanced delivery system that encapsulates quercetin in phytosomes. These phytosomes are spherical structures composed of phospholipids, similar to those of cell membranes, which offer several significant technical advantages:
  • The unique structure of phytosomes increases the solubility of quercetin, a naturally poorly water-soluble flavonoid. By enhancing its solubility, the Phytosome™ technology facilitates the intestinal absorption of quercetin, allowing for greater availability of the active compound in the bloodstream and thus increased efficacy.
  • Phytosomes improve the cellular assimilation of their contents due to an increased affinity with lipid cell membranes. This compatibility enables the phytosomes to merge more easily with the membranes of target cells, delivering quercetin directly inside the cells without prior degradation by digestive juices or by the liver's first-pass metabolism.
  • The Phytosome™ technology helps maintain the integrity of quercetin to avoid intestinal degradation.
  • Phytosomes offer protection against oxidation and decomposition of quercetin, ensuring prolonged preservation of its purity and biological activity.

Discover Clinically Proven Health Benefits for Respiratory Health

  • Superior Bioavailability: Quercetin, a flavonoid, is presented here in the patented form Quercefit®. Thanks to Phytosome™ technology, this form of quercetin is encapsulated in a phospholipid matrix, significantly improving its solubility and bioavailability. This means that the body can absorb and use quercetin more effectively. Although quercetin does not yet have any health claims, numerous studies have shown favorable developments in respiratory function, allergic manifestations, and quality of life.

The chart illustrates the effect of Quercefit® on daytime and nighttime manifestations of asthma for two levels of severity: Intermittent Asthma and Mild Persistent Asthma. It compares the reduction in manifestations with standard medical treatment (SM) alone, and SM combined with 250 mg or 500 mg of Quercefit®.

This chart presents the effect of Quercefit® on lung function, specifically on peak expiratory flow (PEF) and maximum expiratory volume in one second (FEV1). It shows the percentage improvement of these measurements over 30 days for both stages of asthma, highlighting the benefits of adding Quercefit® to the standard treatment. A dose-dependent improvement is demonstrated, with a higher dose of Quercefit® showing more substantial improvements in lung function.

  • Clinically Proven Efficacy: Studies have shown that Quercefit® offers significantly higher absorption compared to standard quercetin.

  • Greek Mountain Tea and Blackcurrant Extract:

Rich in Antioxidants: Blackcurrant, containing vitamin C, is a natural antioxidant. Greek mountain tea, known for its concentration of flavonoids, and blackcurrant, rich in vitamin C and polyphenols, work together to support the normal functioning of the immune system in the case of allergies and protect cells against oxidative stress, a key factor in many respiratory problems and allergies.

Tradition and Science: The traditional use of these plants is validated by modern scientific research confirming their efficacy as cellular protectors.

  • Patented Vitamins C and E:

Cellular Protection: The patented forms of these vitamins ensure increased stability and effectiveness. Vitamin C contributes to immune health which plays a crucial role in combating allergies. Vitamin E, a powerful antioxidant, protects cells against damage caused by free radicals.

  • Synergy of Components: The combination of these vitamins with Quercefit® creates a synergy that helps the body function better in response to external attacks on the respiratory tract.

FAQ: Everything about the dietary supplement Respivits

Why choose Respivits for seasonal allergies?

Respivits is enriched with Quercefit®, an optimized form of quercetin. Although it does not yet have any health claims, numerous studies have noted a favorable development of respiratory function and allergic manifestations.

How does the Phytosome™ technology enhance the effectiveness of Respivits?

The Phytosome™ technology encapsulates active compounds such as quercetin in a phospholipid matrix, which mimics cell membranes. This not only increases the solubility and absorption of the active compounds but also their ability to cross the intestinal barrier and reach target cells, thus enhancing effectiveness.

What other ingredients are present in Respivits and their benefits?

Besides Quercefit®, Respivits contains Greek mountain tea extract, known for its richness in flavonoids, and blackcurrant, which is a concentrated source of vitamin C and polyphenols. Vitamin C works in synergy with Greek mountain tea to strengthen the immune system in the case of allergies and helps combat oxidative stress with the addition of vitamin E.

Vitamin C is mentioned as patented in Respivits. What is its specific role?

The patented form of vitamin C in Respivits provides increased protection against oxidative stress, a factor often exacerbated by allergic manifestations. Vitamin C also supports normal immune function, essential during allergy seasons.

Is Respivits suitable for everyone?

Respivits is formulated for use by adults who seek to optimize their immunity to cope with allergies and support their respiratory health. However, it is not recommended for children under 12, pregnant or breastfeeding women without prior medical advice.
