April 03, 2010 - Saporo, Japan - Grapefruit juice improved intestinal absorption of coenzyme Q10 (CoQ10) by about 50 per cent, says Japanese researchers in a 2010 study.
The juice inhibits a protein in the membrane of cells called P-glycoprotein (P-gp), which thereby leads to an increased absorption of CoQ10, according to results of a laboratory study published in Food Chemistry.
“We have demonstrated that a higher cellular uptake of CoQ10 was achieved in the presence of grapefruit juice,” wrote the Japanese researchers, led by Ken Iseki from Hokkaido University.
