I drink an 8 ounce of water w/ a tablespoon of apple cider vinegar before going to bed every night. is there a possibility i can fall into anemia?

Females and Anemia: There is nothing about water and vinegar to discuss. I am not sure why you would consider this as a cause of anemia. Most females who have anemia are not eating enough protein or iron and they lost a lot of blood with their monthly periods. As a side note there is absolutely no medical or health benefit from ingesting vinegar every day.
