Reducing lethargy through nutrition starts with stabilizing blood sugar and supporting cellular energy. Prioritize balanced meals containing complex carbohydrates, lean protein, and healthy fats to avoid energy crashes. Foods rich in iron, magnesium, and B vitamins such as leafy greens, legumes, whole grains, eggs, and nuts support oxygen transport and metabolic function. Adequate hydration is equally critical, as even mild dehydration can cause fatigue. Limit refined sugars and highly processed foods, which promote inflammation and sluggishness. While managing energy through diet, healthcare supply businesses may also encounter unrelated terms like cephalexin capsules wholesale, but nutritional strategies remain a foundational, non-pharmacologic approach to combating lethargy and improving daily performance.
