2) Grapefruit Seed Extract and Gastric Lesions
3) Grapefruit Seed Extract as an Antifungal
Yeast cells can have induced programmed cell death due to grapefruit seed extract. Grapefruit Seed Extract has strong antifungal properties and destroys the mitochondrial ribosomal protein which leads to the death of the yeast cells [R11].
4) Grapefruit Seed Extract as a Diabetes Treatment
Diabetic rats were used to determine the effect of Grapefruit Seed Extract and its lowering effect on glucose and lipids. Rats that were treated with the extract exhibited significant decreases in total cholesterol, total triglycerides, and low-density lipids, which was similar effects to the popular drug metformin [R14].
Rats were studied to determine Grapefruit Seed Extract’s effect on lowering blood glucose levels and lipids as well as decreasing cardiovascular disease risk factors. Rats that had received the extract had a reduced risk for cardiovascular disease. The extract may also be able to manage type-2 diabetes [R15].

Negative Effects of Grapefruit Extract
1) Grapefruit Extract Negatively Affects Drug Interactions
Grapefruit juice inhibits cytochrome P450 isozymes involved in drug metabolism. This can lead to a possible overdose and dose-dependent adverse effects. This can lead to serious dose-dependent adverse effects (R).
Other grapefruit products besides the juice are also occasionally implicated, including grapefruit seed extract (R).
However, the inhibition of CYP enzymes seems insignificant. The main chemical that inhibits CYP enzymes is furanocoumarin. According to one analysis, grapeseed extract contains 1/1000 of the level in the juice (R). If this is true, then furanocoumarin would have insignificant effects on CYP enzymes.
2) Grapefruit Seed Extract Can Contain Synthetics
The extract has synthetic disinfectants such as benzethonium or benzalkonium chloride. A study showed that 7 out of 9 specimens had these synthetic disinfectants (R).
The grapefruit seed extract sold in the stores is different than the natural seed extract (R).
