vitamin e is supposed to be good to soften scar tissue. But, I would investigate in getting these things the natural way, rather than just popping pills because vitamin pills are usually not as easily absorbed by the body as the vitamins are if taking in via food. Maybe add some foods that are rich in vit e and folic acid to your diet.

From what I read when it comes to healing after a VBaC, all the healing is done within the first 3-6 months. So it is probably not really about healing your uterus, but rather about making the scars more pliable and strengthening the uterus.

All the best with the planned pregnancy and VBa2C. And good on you for being so positive and pro-active.
