After an acute viral illness, many people still feel unwell because their bodies are low on vitamins and trace elements. This insight comes from Olga Shuppo, the scientific director of the Grand Clinic network of immunorehabilitation and preventive medicine clinics, who spoke with socialbites.ca.
She notes that during illness the body mobilizes every available resource to fight the infection, often drawing on internal reserves. When recovery begins, the body can enter a state of “deficiency,” particularly if there is no deliberate replenishment of vitamins and minerals. The result can be lingering fatigue, reduced energy, and a slower pace of healing. A proper recovery plan should consider replenishing these nutrients to support the body as it returns to full strength.
The doctor emphasized that post-recovery vitamin and micronutrient replenishment is important, but professional medical guidance is advised because certain nutrients can interact with conditions or medications. A clinician can determine which supplements are appropriate and establish safe dosages.
Deficiencies in zinc, vitamin C, vitamin E, selenium, magnesium, vitamin D, and B vitamins are commonly observed after viral illnesses. B vitamins, in particular, play a critical role in supporting detoxification processes, helping the body eliminate accumulated toxins that can hinder overall well-being after an infection. When B vitamin levels are low, detoxification may be impaired, allowing toxins to accumulate and potentially impact health outcomes. [Shuppo, Grand Clinic]
Additionally, lingering weakness and daytime sleepiness can be attributed to mitochondrial dysfunction. Mitochondria are the cellular powerhouses responsible for energy production. Viral infections such as influenza and coronavirus infections can damage mitochondria, reducing energy output at the cellular level and contributing to a sense of fatigue. This underlines the importance of addressing energy metabolism in recovery plans. [Shuppo, Grand Clinic]
According to the doctor, physical therapy can be a valuable component of recovery. Health professionals may suggest approaches such as intermittent hypoxic training, hydrotherapy, or advanced breathing and pressure therapies to support energy restoration and functional resilience. These modalities can help improve circulation, oxygen utilization, and overall vitality as healing progresses. [Shuppo, Grand Clinic]
In any case, increasing daily water intake is a simple, practical step after an illness. Hydration supports metabolic processes, helps maintain electrolyte balance, and aids in toxin elimination. Some clinicians advocate temporarily using alkaline mineral waters to help rebalance body pH during the recovery period, followed by a return to a balanced hydration strategy as the system stabilizes.

Despite the guidance above, it is essential for individuals with allergies or other health considerations to consult with a healthcare professional before making changes to their supplementation or treatment plan. A personalized assessment can ensure that choices align with medical history, current medications, and specific health goals. [Shuppo, Grand Clinic]
