I think transdermal (sustain alpha), IBE Reverse or maybe try a sublingual like LG T-911. However, they are not always the cheapest. As far as just regular resveratrol, Bioperine and quercetin are used to help increase the bioavailability. You can always try nutra's bulk caps that includes bioperine. You can fine LG T-911 for around $25 if you look around. Resveratrol is not cheap and it will be hard to find an effective product that is very inexpensive.
