Few remedies can be used for various ailments and applications without adding other components.  Grapefruit seed extract is one of those all in one toxic-free solutions that can be used internally, externally and as a potent cleaner and disinfectant.
For those traveling internationally its an amazing solution for treating water and leafy greens that can produce infections and diarrhea in those with sensitive stomachs.  In most cases, just 6-10 drops in an 8-ounce glass of water will do the trick.

“Grapefruit Seed Extract is associated with the following potential health benefits:

  • Powerful natural antiseptic.
  • Antiviral and anti-fungal agent.
  • Possible anti-cancer properties.
  • Promotes the healing of wounds and scar tissue.
  • Possible cholesterol-lowering properties due to the presence of the flavonoid naringin (a well-known plasma lipid reducer and plasma antioxidant activator).
  • Excellent remedy for toenail fungal infections.
  • Treatment for sinus, vaginal and topical skin infections.
  • Environmentally-friendly fruit and vegetable wash for removing toxins.
  • Effective preventative for Candida and other forms of yeast infection.
  • Inhibits the formation of harmful intestinal organisms, including Giardia, without reducing levels of healthy bowel flora.
  • Acts as a natural preservative for cosmetics.
  • Can replace chlorine in swimming pools, public baths, water, and sewage treatment centers, and it also used as a general water-purifying mechanism.
  • May reduce the chances of developing coronary heart disease in high-risk patients due to high pectin content in Grapefruit seed extract.
  • Possible anti-biotic activity.
  • Aids to alkalize the body, and is one of the world’s most alkaline forming foods, helping to stabilize acidic pH levels, a central component for health rejuvenation.
  • Great general immune system booster. A study from The Journal of Alternative and Complementary Medicine found that grapefruit-seed extract was effective in killing over “800 bacterial and viral strains, 100 strains of fungus, and a large number of single and multi-celled parasites.”² No other naturally-occurring anti-microbial can come close to these results.”

grapefruit seed extractWhy would I want to use this product?

As a natural, non-toxic compound, our GSE liquid concentrate has many uses. Internally, the concentrate is useful as a supportive treatment for a wide variety of ailments, including Candida infections, sore throats, and intestinal upset.

How can the product be non-toxic if it is so potent?

Extensive testing by independent laboratories and universities around the world has proven the concentrate to be safe for human consumption. It is effective against pathogens because it belongs to a family of compounds known as quaternary compounds. This family is best known for benzylkonium chloride and benzylthonium chloride, as well as the infamous quaternium group, a very toxic antimicrobial preservative used in the cosmetics industry. While grapefruit seed extract is molecularly similar to these compounds, there are some profound differences in structure and function. Studies to date indicate that there is little danger from either short-term or long-term internal use.

What is the pH of this product?

The concentrate is about 2.2 — very acidic. This is why we recommend that you dilute it before use. We do not know if the product becomes alkaline when ingested the way orange juice and other citrus foods do.

Is this product safe for use with children?

Yes. The extract is frequently used in pediatric medicine in applications for diaper rash, ear infections, abrasions, etc. Common sense dictates using a very diluted solution on an infant.

What about using it for my pets?

Since the concentrate is safe for consumption, it is well-suited for animal uses. The extract can be added to an animal’s water or food.

What about the “grapefruit juice effect”?

There is a phenomenon known as the “grapefruit juice effect”. Two components found in grapefruit juice, naringin and naringenin**, inhibit production of an enzyme in the intestinal tract, thus increasing the rate of absorption for certain classes of drugs (including some antihistamines, birth control pills, anti-epilepsy medications, and some antibiotics).

In some instances, as in low-dose birth control pills and some uses of antibiotics, this can be favorable because the net result is more efficacy, less drug. In other cases, especially for anti-seizure medicines, blood levels need to be monitored and maintained very carefully. The customer would be well-advised to check with his doctor or pharmacist to see if there is any interaction between his medication and the naringin and naringenin**.

**NOTE: NutriBiotic GSE contains only 0.1% of these compounds.

Is there anything I can’t use the concentrate for?

We do not recommend using it in your eyes, even in a dilute form. We also advise users to dilute the extract before use. If you place a drop of the product on your tongue, it will burn. Sensitive skin areas also will end up with an unpleasant irritation if the concentrate is used full-strength.


Vegetable Glycerin (67%). An inert substance derived from palm and coconut. Used as a carrier for the active ingredient. We use only food-grade vegetable glycerin that tests free of pesticide residues.

Citricidal (33%). Extract of the pulp, seed, and inner rind of grapefruit. The raw material goes through a multi-stage patented process.

You can purchase GSE at your local healthfood store or online.
