@ktdolly How to Increase White Blood Cells Current research doesn't show that there's any specific diet that will increase your body's production of WBCs. But our bodies do use materials in proteins to make WBCs. Therefore you should: Eat high-quality proteins including fish, poultry, beef, eggs, milk, Greek yogurt, and beans. Take vitamin B12 and folate (folic acid), or a multivitamin with those ingredients, if you don't eat these proteins. The body uses vitamin B12 and folate to make WBCs. If you're having chemotherapy, talk to your doctor or nutritionist before taking supplements because some of them shouldn't be taken with some cancer treatments. In order to protect yourself, you: Wash your hands frequently with soap and water or a hand sanitizer. Stay up to date on your vaccines, including your flu and COVID shots. Avoid crowds, or wear a mask in a crowd. Prevent the spread of germs in the kitchen by washing fruits and vegetables before eating, using a separate cutting board for meat to avoid cross-contamination, and cooking meat to the proper temperature. Wear gloves when picking up pet waste or infant diapers with poop. Wash your hands when you've finished the task. Good Luck!!!

This is a good question and I have a similar one as to what happens when your immune system gets “too weak” on B cell depleters. I think the normal protocol is to not only monitor your wbc but also to see how your body reacts to sicknesses. I would def ask your doctor what the game plan is for your wbc and being on kesimpta long term. Have you discussed with them?
