Immune defenses in autumn: how to strengthen them with natural remedies

With the arrival of autumn, our immune system is exposed to new challenges : temperature changes, an increase in respiratory viruses, and a physiological decrease in energy. The most common symptoms related to lowered immunity include frequent colds, fatigue, sore throats, muscle aches, and frequent relapses.

How can we naturally support our immune system in autumn?
In this article, we'll explore the most common causes of seasonal immune deficiency and the most effective natural strategies for addressing it—with targeted support from nutrition, herbal medicine, and supplements.

Why does the immune system weaken in autumn?

The immune system is a complex set of cells and molecules that protects the body from viruses, bacteria, and foreign agents. During autumn, certain factors tend to compromise its balance:

• Reduced sun exposure → less vitamin D, essential for immunoregulation.

• Return to a frenetic pace → stress and psychophysical load affect the immune response.

• A less varied diet → can lead to vitamin and antioxidant deficiencies.

• Longer periods spent in closed environments → facilitate the transmission of respiratory viruses.

A “tired” immune system responds less effectively to pathogens, increasing the risk of recurrent or longer-lasting infections.

How to strengthen your immune system naturally

Lifestyle care

To strengthen your defenses in autumn it is important to start from the basics:

• Diet rich in micronutrients : favor fruit, seasonal vegetables, whole grains and quality protein sources.

• Regular exercise : Even a daily walk improves circulation and reduces inflammation.

• Quality sleep : sleeping at least 7 hours a night promotes immune regeneration.

• Stress management : Meditation, outdoor activities, or scheduled breaks help maintain hormonal and immune balance.

Phytotherapy: plants that stimulate the immune system

Many medicinal plants have been shown to positively modulate the immune response . Among these:

• Echinacea : stimulates T lymphocytes and macrophages; useful for preventing and managing seasonal infections. It is found in liquid formulations such as Dr.Tili Echinacea Essenziali , or in combination with other active ingredients in Dr.Tili Immune Defense Syrup .

• Acerola : a natural source of vitamin C, it promotes the production of Natural Killer cells and helps counteract oxidative stress. It is present in both Dr. Tili's Acerola Essenziali Drops and Dr. Tili's Acerola Echinacea Vitamin C Tablets , along with echinacea and eleutherococcus.

• Papaya : Rich in antioxidants and digestive enzymes, it supports metabolism and immune response. Present in Dr. Tili Immune Defense Syrup .

• Eleutherococcus : adaptogenic tonic, improves resistance to viruses and bacteria, useful during seasonal changes. Included in Acerola Echinacea Vitamin C Dr.Tili .

• Blackcurrant : has a natural antihistamine effect, useful for allergies and seasonal inflammation. Dr. Tili Ribes Nigrum Essential Drops promote the anti-inflammatory response and help with sinusitis, colds, and allergic rhinitis.

• Cat's Claw and Astragalus : profound immunostimulants, they promote the production of lymphocytes and interferon, effective against respiratory viruses. They are present in Dr. Tili's T-Immuno Mix Immune Defenses , which also combines propolis and lactoferrin for rapid synergistic action.

Vitamin C and Vitamin D: Two Essential Allies

Vitamin C

Essential for the development of T lymphocytes and NK cells, vitamin C is a powerful immunostimulant and antioxidant. Concentrated plant sources like acerola ensure its bioavailability.

• Dr.Tili Essential Acerola Drops provide a highly titrated extract, useful during times of increased exposure to viruses.

• Dr.Tili's Acerola Echinacea tablet formulation is ideal for continuous use.

Vitamin D

In autumn, vitamin D deficiency is very common, especially in those who spend little time outdoors. Vitamin D3 is crucial for T-cell activation and proper immune regulation.

• Dr.Tili Vegan Vitamin D 2000 IU uses Iceland moss extract, also suitable for vegan diets.

• Vita D'oro Gocce Dr.Tili offers a highly bioavailable oily formulation, useful for maintaining optimal levels during the cold season.
