Grapefruit Seed Extract is one of three types of supplements that can be made from a grapefruit. The others include a concentrate that is made from the entire grapefruit including the skin and rind, an extract that is made entirely from the grapefruits rind, and lastly, an extract that is made from only the seeds which we will further review.

List of Ingredients

Research on the Grapefruit Seed Extract does not list any other ingredients other than the seeds from the grapefruit. The process involves grinding the grapefruit seeds and pulp into an acidic liquid that contains polyphenolic compounds that include quercitin, helperidin, neohelperidin, apigenin, naringin, campherol glycocide, poncirin, and rutinoside. Most times Vegetable Glycerin is added to subdue the bitter and acidic tastes.

Grapefruit Seed Extract can cost between $10 to $25 for a one month supply and provides about 130 mg per dosage. Not everyone can take Grapefruit Seed Extract, such as people that are taking immunosuppressant medications, any cholesterol lowering medications, and even antihistamines.

Product Features

Grapefruit Seed Extract is said to supply a remedy for IBS (Irritable Bowel Syndrome) that includes diarrhea, constipation, as well as abdominal cramping or discomfort. Grapefruit Seed Extract can help with germ-killing, but researchers cannot be sure that those abilities actually come from any preservatives in the extracts.

    i have taken this product. gse grapefruit seed extract 2 oz size by nutribiotic in lakeport ca 95453. it was recomended by a homeopathic dr corrine allen…it caused extreme lower abdomenal pain. therefore only took it briefly. i take ursodial 250 tabs twice daily, and furosemide 40 mg once or twice a day, and spironolactone 50 mg once or every other day…these are for primary biliary cirrosis of the liver (probably generational thing),diagnosed in 2002..are these compatible…my regular primary internal med dr recently said she had read in her new medical journal that gse can be helpful for the liver issue??? any info to share some light on this would be appreciated. thank you g
