It is completely natural to want to strengthen your body after recovering from COVID-19, especially while tapering off your steroid, Medrol (methylprednisolone). Since steroids temporarily suppress your immune system, the safest approach right now is focusing on gentle, natural recovery. Prioritize nutrient-rich foods, stay well-hydrated, and ensure you get plenty of restorative sleep. Gentle movement, like short walks, is wonderful, but avoid intense exercise until you have fully finished your taper. Please consult your prescribing doctor before starting any new supplements or vitamins to ensure they do not interfere with your gradual steroid taper.
