I would start with diet - cutting out all junk foods and eating as healthy as possible, then add vitamins & supplements..

Consider testing to find out what your vitamin levels are at now with a full blood work up..
Then use that info to add vits & supps for best results..

If you smoke that is a whole other negative to health..and more vitamins /supplementing are needed to offset that if you can't quit..

The useful sticky threads in upper area of each forum have saved info - and our search tool can be very helpful too..

Maybe something it this forum might be helpful too..

Sometimes vitamins & supplements just can't do it all...
