Recent scientific studies have proven that COVID-19 is a systemic disease that affects not only the respiratory system but also the cardiovascular, digestive, immune, and other systems of the human body. Recovery after the virus is a long and difficult process, as the body weakened by such illness requires time and support.
The impact of COVID-19 on the immune system
The main defenders of the immune system are B- and T-lymphocytes. B-cells produce immunoglobulins (antibodies) and preserve memory of past infections, enabling a faster and more effective response to reinfection. T-cells destroy infected cells, preventing further spread of the virus.
Statistics show that 83% of people recovering from COVID-19 experience lymphocyte deficiency for 4–11 weeks after full recovery. This makes them more vulnerable to infections, including re-infection with SARS-CoV-2.
Post-COVID patients often experience symptoms such as:
- Frequent unexplained headaches;
- Increased fatigue and physical weakness;
- Apathy and lack of energy;
- Drowsiness and sluggishness;
All of these are linked to a weakened immune system. To restore balance, the body needs additional vitamins, minerals, and especially omega-3 fatty acids, which play a crucial role in immunity. The richest natural sources are cold-pressed plant oils such as camelina oil, flaxseed oil, and black cumin oil. These oils are also rich in natural antioxidants that protect the body from free radicals and slow oxidative processes, which typically intensify when the immune system is weakened.
Benefits of plant oils for immune system recovery
Cold-pressed oils for immunity are truly unique products. They contain vital bioactive substances essential for proper body function:
- Omega-3 fatty acids – strengthen cell membranes, reduce inflammation, and enhance the production of prostaglandins and resolvins, improving immune response;
- Antioxidants (especially vitamin E) – protect cells from oxidative stress, helping prevent flare-ups of chronic illnesses;
- Phytosterols – naturally reduce cholesterol absorption, improve blood flow, and lower the risk of cardiovascular problems;
Additionally, plant oils are necessary for the production of surfactant – a substance that coats the alveoli in the lungs, serving as a barrier against pathogens and viruses. Surfactant prevents harmful microbes from attaching to the respiratory tract and supports full lung function.
Important: only raw, organic, cold-pressed oils retain these valuable properties. You can buy them or even make them at home, ensuring 100% natural, fresh, and flavorful oils that support health, energy, and immunity.
