Hi, Iron deficiency can be treated using natural remedies, including: * Eating iron-rich foods: Include foods like leafy greens, red meat, poultry, seafood, beans, lentils, nuts, and seeds in your diet. * Vitamin C: Eat foods rich in vitamin C such as citrus fruits, bell peppers, tomatoes, and broccoli as they enhance the absorption of iron. * Blackstrap molasses: It is a good source of iron and can be added to drinks or used as a sweetener. * Herbs: Nettle, dandelion, and yellow dock are herbs that are rich in iron and can be brewed as a tea. * Cooking in cast-iron pans: Cooking acidic foods in cast-iron pans can increase the iron content in the food. Regarding Injectafer, it is important to follow the advice of your healthcare provider regarding how often to receive treatment. The frequency of treatment may depend on the severity of your iron deficiency and your response to treatment. If you are experiencing bad headaches as a side effect of the treatment, it is important to discuss this with your healthcare provider. They may be able to adjust the dose or suggest alternative treatments. There are liquid iron supplements available, such as ferrous sulfate liquid or ferrous gluconate liquid, but it is important to discuss the use of these supplements with your healthcare provider before taking them. They may be able to suggest the best supplement for your individual needs and monitor your response to the supplement. Take care. Hope I have answered your question.
