Immune system: the support of Nutraceuticals for natural defenses

The immune system plays a vital role in our overall health.
It defends us against disease and infection, enabling us to prevent viral and bacterial illnesses, especially during periods where seasonal ailments force millions of people to bed.

To ensure optimal immune system function, more and more people are turning to nutraceuticals, which offer natural and effective support.
Vitamins, minerals, plant extracts and other key ingredients can strengthen immune defenses and help maintain a healthy immune system.

Strengthening the immune system: the benefits of nutraceuticals

The immune system plays a crucial role in our overall well-being, defending us from pathogens and keeping us healthy, so it is essential to understand how the immune system works and the importance of properly supporting it.
Nutraceuticals prove to be valuable allies in boosting the immune system without any particular contraindications and effectively.

Dietary supplements enriched with vitamins, minerals and plant extracts can provide our immune system with the nutrients it needs to function optimally. These nutraceuticals can help boost immune responses and promote a healthy balance of gut flora. Integrating them easily into your daily routine will provide optimal protection and valuable support for your immune system, strengthening your body’s natural defense.

But what exactly are nutraceuticals? These are food or supplement products that combine elements of nutrition and pharmacology to provide health benefits. Unlike drugs, nutraceuticals harness the beneficial properties of vitamins, minerals and plant extracts to strengthen the immune system. These powerful ingredients work synergistically to boost the immune system. Essential vitamins and minerals help strengthen the immune system, while plant extracts help thin bronchial secretions, promoting their elimination. Natural antioxidants reduce free radicals derived from inflammation, while probiotics balance gut flora, which is critical for optimal immune health. In addition, amino acids support cell function by enhancing the immune response.

Immune defenses: how they work and why it is important to strengthen them

The immune system is a complex mechanism comprising several essential components.

Some of the key elements of the Immune System

There are two types of immune response:
1. Innate immunity, which is nonspecific, rapidly activated and always operative;
2. Acquired or adaptive immunity, which is specific, activated more slowly and is dependent on infection and can develop an immunological memory.

The immune response begins with the recognition of surface antigens, molecules that identify what does not belong to the organism. Immune system cells are activated to boost defenses, while a regulatory system ensures that the response is balanced to prevent damage to the body.

At the end of the process, most white blood cells are self-destructed or phagocytized, while other cells may persist as memory cells.

One of the conditions that stimulate immune system activation isseasonal influenza, a contagious respiratory infection caused by particularly harmful viruses.

Seasonal flu: protecting the elderly and children from violent symptoms

From what we learn from timely reports from InfluNet-the national epidemiological and virological influenza surveillance system-the seasonal flu of 2022-2023 has reached unprecedented peaks.
Not only in the number of cases, but also as symptomatology, with very high fever spikes and really violent upper and lower respiratory inflammatory reactions.
Although most people take a few days to two weeks to fully recover, some fragile categories develop major complications, which can cause problems for life.
These include people over the age of 65, individuals with certain chronic medical conditions (such as asthma, diabetes, or heart disease), pregnant women, and children under the age of 5.
And it is precisely for these at-risk individuals that Alsa Lab has developed its“Flu Line” line of immune defense supplements designed to prevent flu symptoms and support recovery during the convalescence phase.

The best supplements for the immune system: the proposal of Alsa Lab

When weakened immune defenses are not caused by specific diseases or we simply want to strengthen our immune system, the use of natural remedies and supplements can be helpful.

High-quality immune system nutraceuticals can make a difference in promoting effective natural defense.
Alsa Lab has developed a line of products aimed at boosting immunity based on highly effective ingredients to combat seasonal ailments and provide relief:

  • Vitamin C, a powerful antioxidant that not only boosts the immune system but also fights oxidative stress;
  • Vitamin D, synthesized through sun exposure or through supplements, plays a crucial role in regulating immune responses;
  • Zinc, an essential mineral for supporting the immune response;
  • Echinacea extract, a medicinal herb with antiviral and immune-stimulating properties, a valuable ally for immune health.
