As long as you are eating fruits,vegetables,nuts,lean meats,whole grains,drinking enough water,and dairy products you will get enough vitamins,protein and minerals.Hopefully you are avoiding smoking
and drinking alcohol,drugs etc. the healthier you are the better your restoration will go.I doubt that any supplements would help much.You could ask your doctor about about HGH or topical testosterone cream which I have heard about some men using.
In this book ["The Joy of Uncircumcising"] I found Dr. Michael Scott. He prescribed testosterone cream for me four years ago. All I can say is, this stuff really works. It promotes skin growth on the shaft skin. If you want to use this, tape up as you normally would, then apply it behind the tape once or twice a day. You don't want to get any on the tape.
