6,7-Dihydroxybergamottin
Mechanism of Action +
DHB acts as a mechanism-based (irreversible) CYP3A4 inhibitor, meaning its inhibition is time- and concentration-dependent and not immediately reversible. Pharmacokinetic data from grapefruit juice studies (which contains DHB as a primary active constituent) show serum concentrations of 38–43 µmol/L following consumption. IC50 for CYP3A4 inhibition is reported at approximately 25 µM. DHB does not appear to directly inhibit P-glycoprotein. Tmax and standalone half-life data for isolated DHB supplementation in humans are not well established in the available literature.

Everything About 6,7-Dihydroxybergamottin Article
## What is 6,7-Dihydroxybergamottin?
6,7-Dihydroxybergamottin, also known as DHB, is a natural compound found in grapefruit and other citrus fruits. In the dietary supplement industry, it is included in formulas with the theoretical purpose of enhancing the bioavailability of other ingredients. It is believed to work by inhibiting certain enzymes in the digestive system that would normally break down other compounds before they can be fully absorbed.
## What It Does: The Theory
The intended mechanism of 6,7-Dihydroxybergamottin is the inhibition of cytochrome P450 enzymes, particularly CYP3A4, which are located in the liver and intestinal wall. These enzymes are responsible for metabolizing a wide range of substances, including many dietary supplement ingredients and pharmaceutical drugs. By inhibiting these enzymes, DHB may allow co-administered compounds to bypass this 'first-pass' metabolism, potentially leading to:
* Higher peak blood concentrations (Cmax) * Increased total absorption (bioavailability) * Longer duration of action (extended half-life)
**It is critical to note that the provided source materials for this analysis contained no scientific studies to confirm these mechanisms or effects.** The information presented here is based on the theoretical reason for its inclusion in supplements.
## What The Research Says
Unfortunately, the provided sources yielded no clinical research on 6,7-Dihydroxybergamottin. The primary evidence sources from Examine.com and PricePlow.com both resulted in '404 Page Not Found' errors. Therefore, based on the available materials, there are no human trials, meta-analyses, or scientific reviews to support any claims regarding its efficacy, safety, or mechanism of action.
The only available data is from a survey of commercial products, which indicates that supplement manufacturers commonly include it in their formulas, but this does not constitute scientific evidence.
## Dosing Guide
There is no clinically established dosage for 6,7-Dihydroxybergamottin, as no research was provided. A survey of 19 products in the market found a consistent dose of **50 mg**. However, this dose is based on industry practice rather than clinical evidence. Without scientific studies, it is impossible to determine a minimum effective dose, an optimal dose, or a safe upper limit.
## Forms Compared
Insufficient data was available to compare different forms of 6,7-Dihydroxybergamottin.
## When & How To Take It
Given its theoretical role as a bioavailability enhancer, 6,7-Dihydroxybergamottin should be taken concurrently with the other ingredients it is intended to affect. It is almost always found within a multi-ingredient pre-workout, fat burner, or other similar formula, so it should be consumed as directed on the product's label. There is no information on whether it should be taken with or without food.
## Stacking
6,7-Dihydroxybergamottin is exclusively a 'stacking' ingredient. Its sole purpose is to be combined with other compounds to enhance their effects. However, since no studies were provided, any specific stacking recommendations would be purely speculative.
## Who Should Take It
There is insufficient evidence from the provided sources to recommend 6,7-Dihydroxybergamottin for any specific population or goal.
## Who Should NOT Take It
**Crucially, anyone taking prescription or over-the-counter medications should avoid 6,7-Dihydroxybergamottin.** Its potential to inhibit drug-metabolizing enzymes could lead to dangerously elevated levels of medication in the bloodstream, increasing the risk of side effects and toxicity. This is the same reason patients on certain medications are advised to avoid grapefruit juice. Always consult with a physician before using any supplement containing this ingredient if you are on medication.
## The Bottom Line
6,7-Dihydroxybergamottin is an ingredient used in supplements with the goal of enhancing the absorption and longevity of other active compounds. While the theory behind its mechanism is plausible, the provided sources contained a complete lack of scientific evidence to support its use. The only data available is its common inclusion in products at a 50mg dose. Due to the potential for serious drug interactions, extreme caution is advised, especially for individuals on medication.
