Flu: the most effective dietary supplements

Influenza is a common respiratory infection, often seasonal, caused mainly by influenza A and B viruses. It spreads through droplets expelled when coughing or sneezing and presents with symptoms such as fever, muscle aches, and cough. While this illness is mild for some, it can be more serious for vulnerable people, such as the elderly or those with chronic conditions. Effective management relies on strengthening the immune system and appropriate symptomatic treatments. Influenza viruses are divided into three types (A, B, and C), with only A and B responsible for seasonal epidemics. The rapid mutation of strains, especially type A, complicates prevention through vaccination. Symptoms generally appear after an incubation period of 1 to 4 days and are characterized by high fever, body aches, intense fatigue, and respiratory symptoms.

Symptoms

The most common signs include high fever, muscle pain, headaches, and respiratory symptoms such as coughing and nasal congestion. In case of complications, influenza can progress to severe respiratory infections like pneumonia, especially in the elderly or immunocompromised individuals. It is common to confuse a cold with the flu because their symptoms are similar. However, the flu is generally more severe and has a more sudden onset than a cold. A cold, which can occur at any time of year, develops gradually with moderate symptoms such as a runny nose, mild fatigue, and a mild cough. In contrast, the flu comes on abruptly, often in winter, with fever, body aches, headaches, and profound fatigue that can immobilize the patient.

Immune Support

Phytotherapy Plants are well-known allies for combating the flu and strengthening the respiratory system. Elderberry (Sambucus nigra) is particularly recommended for its immunostimulant and antiviral effects; it can be taken as a syrup or infusion to relieve flu symptoms. Echinacea (Echinacea) is also beneficial, as it stimulates immunity, reducing the duration of flu symptoms and preventing respiratory infections. It is often used as a preventive treatment or at the first signs of infection. Essential oils such as eucalyptus (Eucalyptus globulus), which has decongestant and antiseptic properties, or ravintsara essential oil may also be used. Trace elements Trace elements are essential for immune support during the flu season. Copper, for example, has anti-infective properties and helps strengthen the body's defenses against viral infections. Zinc, known for its antiviral action, plays an essential role in the immune response and helps reduce the duration and severity of symptoms. Selenium, a powerful antioxidant, can help modulate the intensity of infectious symptoms. Lifestyle and Prevention Good lifestyle habits can be a key factor in preventing the flu or reducing its symptoms. Sufficient rest is essential to allow the body to mobilize its defenses against the virus. Regular hydration helps eliminate toxins and maintain good secretion fluidity. Finally, a diet rich in vitamins C and D contributes to strengthening immunity: vitamin C, found in citrus fruits, kiwis, and green vegetables, supports immune defenses. Vitamin D, found in fatty fish and eggs, plays a key role in immune regulation.
