6′,7′-Dihydroxybergamottin (DHB) is a natural furanocoumarin found mostly in grapefruit juice and Seville orange juice. DHB is believed to be responsible for so-called grapefruit juice effect.
Why is 6′,7′-Dihydroxybergamottin Found in Supplements?
6′,7′-Dihydroxybergamottin is sold as “anabolic amplifier” and is supposed to increase the absorption of supplements, drugs, oral anabolic steroids and even food. DHB was reported to be very effective at inhibiting the cytochrome P450 CYP3A4 enzyme activity in intestine and liver , which is responsible for decreasing small foreign organic molecule absorption.
Active ingredients (such as 6′,7′-DHB) in grapefruit juice are responsible for greater bioavailability of drugs after oral dosing but not after intravenous administration of the same drugs. It has been shown that 6-beta-hydroxylase activity (exhibited by CYP3A4 enzyme ) plays and important role in metabolism of the anabolic steroids [6]. Both in vivo and vitro hydroxylation at 6-beta-position catalyzed by CYP3A4 enzyme was reported for testosterone, progesterone, cortisol and androstenedione, as well as for the synthetic compounds, methandrostenolone (metandienone [trade names Averbol, Dianabol, Danabol, Dbol]), budesonide and dexamethasone . Therefore, many bodybuilders couple their oral anabolics with 6′,7′-DHB and/or bergamottin. In this case, with greater bioavailability comes greater toxicity and adverse reactions (most commonly gynecomastia, high blood pressure, acne and male pattern baldness).
In 2014 Karen M. VanderMolen et al. [7] analyzed six sports nutrition supplements that were labeled to contain the furanocoumarin(s) bergamottin and/or 6′,7′-dihydroxybergamottin. Contrary to the product labeling, four of the supplements contained no detectable quantities of either furanocoumarin, while two of the supplements contained minimal amounts. CYP3A inhibition by this low amounts of bergamottin and DHB was greater than it could be accounted for by the two furanocoumarins which suggests the presence of other potent or highly abundant CYP3A inhibitors.
