Blueberry Bran Muffins

I've had low iron which means iron supplements which means problems with constipation so I've been trying to add more fiber into my diet.  After eating all the storebought muffins we purchased I decided to make my own bran muffins and hopefully make them a bit healthier.  I found this recipe on recipezaar and made them pretty much as written.  I think they took about 25 minutes to cook and I used blueberry yogurt.  I would advise people to use the half applesauce, half oil combination but I didn't because I couldn't find my applesauce.  It would make the recipe that much healthier.  Hope you enjoy!
