To naturally enhance your hemoglobin levels in 10 days, focus on incorporating iron-rich foods like spinach, red meat, lentils, and fortified cereals into your diet, while also including vitamin C sources such as citrus fruits, strawberries, and bell peppers to aid in iron absorption. Avoid consuming calcium-rich foods or beverages like dairy products alongside iron-rich foods, as they can inhibit absorption. Stay hydrated, get plenty of rest, and avoid tea and coffee, which can hinder iron absorption. Consider incorporating herbal supplements like nettle and dandelion under the guidance of a healthcare professional, and engage in regular exercise to improve blood flow.
