If you have Crohn's disease, you might need supplements to help get the necessary nutrients, as the condition can affect nutrient absorption. Your doctor may recommend certain supplements to manage symptoms and prevent deficiencies. Key supplements include: Calcium with vitamin D for bone health, Folic acid for healthy cells, Iron to prevent anemia, Magnesium for energy and muscle function, Potassium for muscles and blood pressure, Vitamin B12 for nerve health, Vitamin D for calcium absorption and inflammation control, Vitamins A, E, and K for cell health and infection fighting, and Zinc for immune support. Some liquid supplements like Enlive and Peptamen might be suggested if eating is difficult. Always consult your doctor before starting any supplements, as some may trigger symptoms or have side effects.
