Or Is It?
While there are a few studies negating the benefits of grapefruit seed extract, many other studies provide substantial data that’s good to know about. And then there’s lore from tradition, which also has proven merit.
One study published in 1999 and another in 2021, indicate that the perceived benefits of grapefruit seed extract were more of an effect of the presence of synthetic antimicrobial compounds[1]https://www.herbalgram.org/news/press-releases/2017/botanical-adulterants-bulletin-highlights-the-presence-of-synthetic-antimicrobial-compounds-in-grapefruit-seed-extract/ and/or the solvent (solution) used for extracting GSE. [2]https://pubmed.ncbi.nlm.nih.gov/10399191/[3]https://pubag.nal.usda.gov/catalog/7297762 Conversely, many other studies have provided what would seem to be a plethora of substantial data.
So we’re sharing here, common uses and benefits of grapefruit seed extract as well as the links to scientific studies, so that you can discern for yourself, what makes the most sense to you.
One Source of Confusion on GSE
Another issue with the information on grapefruit seed extract (GSE) is that it is often confused in articles online with another seed with beneficial properties: grape seed extract, which is also called GSE!
The benefits of grapefruit seed extract are different than the benefits of grape seed extract.
While grapefruit seed extract is often cited as being good for teeth, we didn’t find the research to substantiate that. When searching for grapefruit seed extract benefits, the majority of the search results present grape seeds rather than grapefruit seeds.
The other — and ongoing — source of confusion on just about anything and everything, are the claims by manufacturers of products. The challenge becomes one of discerning fact from hype verified research versus advertising spin.
So friends, until more studies are done, we have to put on our own Sherlock Holmes deerstalker hat and do some of our own armchair research with our specific ailment and possible remedy in mind.
And of course, it is always advisable to consult with your trusted health professional for guidance and best uses.
Even though GSE is identified as a natural antimicrobial, this observation suggests that the GSE antibacterial activity is derived from these synthetic substances such as benzalkonium chloride. Therefore, further research is needed about these controversial issues.
More Studies Are Needed for Greater Clarity
This doesn’t mean that there aren’t any significant benefits to grapefruit seed extract, but rather, that there is confusion and a lack of clarity because of differing results in differing studies.
What’s needed are studies of grapefruit seed extract that do not include any kind of antibacterial medium, but rather, a neutral carrier, such as water or vegetable glycerin rather than alcohol, or synthetic substances that may also have medicinal effect.
We — at GardensAll — are keenly interested in the topic of natural health and healing, especially through the foods we can grow. We’ve had first hand experience of the powerful healing properties of plants and natural foods and herbs. However, we are researchers, writers and editors, not scientists.
While we have researched and studied this topic exhaustively, the more we researched, the less conclusive we became. We started this article with the certainty that we needed only to present examples of the proven benefits. What we found was staunch support, but also valid opposing results
So we present these studies for you to peruse and make your own informed opinions.
Our Take on the Benefits of Grapefruit Seed Extract
How we plan to proceed from here is to continue using grapefruit seed extract, while carefully observing any and all benefits noted.
Further, before using GSE for any of the benefits attributed, we will again dive into the research, of both studies and herbology, of science and lore. We value the relevance of both, and consider first hand experience as important as the exhaustive clarity of laboratory studies.
