Flu: Most Effective Dietary Supplements

The flu is a common respiratory infection, often seasonal, primarily caused by influenza viruses A and B. It spreads through droplets projected during coughing or sneezing and manifests with symptoms such as fever, muscle pains, and cough. While mild for some, it can be more severe for vulnerable individuals like the elderly or those with chronic illnesses. Effective management relies on strengthening the immune system and tailored symptomatic treatments. Flu 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 for 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 cough and nasal congestion. In case of complications, the flu can progress to severe respiratory infections like pneumonia, especially in the elderly or immunocompromised individuals. It is common to confuse the common cold and the flu, as their symptoms are similar. However, flu is generally more severe and occurs more suddenly than a cold. The cold, which can occur at any time of the year, develops gradually with moderate symptoms such as a runny nose, slight fatigue, and mild cough. In contrast, the flu arrives abruptly, often in winter, with fever, body aches, headaches, and significant fatigue that can immobilize the patient.

Immune Support

Herbal Remedies Plants are recognized allies in combating the flu and strengthening the respiratory system. Elderberry (Sambucus nigra) is particularly recommended for its immune-stimulating and antiviral effects; it can be taken as syrup or infusion to soothe flu symptoms. Echinacea is also beneficial because it stimulates immunity, reducing the duration of flu symptoms and preventing respiratory infections. It is often used in preventive courses or at the first signs of infection. Essential oils such as eucalyptus (Eucalyptus globulus), with decongestant and antiseptic properties, or Ravintsara essential oil can also be used. Trace Elements Trace elements are essential for immune support during flu season. Copper, for example, has anti-infectious 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 hygiene can be a key factor in preventing the flu or alleviating its symptoms. Adequate rest is essential to allow the body to mobilize its defenses against the virus. Regular hydration helps eliminate toxins and maintain good fluidity of secretions. Finally, a diet rich in vitamins C and D contributes to enhancing 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.
