DOES IT WORK?
HPBCD is a cyclodextrin derivative used in pharmaceutical and supplement formulations to improve the solubility and absorption of poorly water-soluble ingredients. It forms inclusion complexes where the hydrophobic molecule sits inside the cyclodextrin ring. It's been used to improve absorption of CoQ10, curcumin, resveratrol, and many drugs. No direct health benefits, but it can make other ingredients work significantly better.
