Grapefruit seed extract is a herbal remedy derived from grapefruit seeds and pulp, with high concentrations of flavonoids that act as antioxidants. It has been shown to have antibacterial, antifungal, and alkalizing properties and can promote skin regeneration and improve immune system function. However, its benefits depend on concentration and individual response, and claims of its effectiveness vary widely. While there are no established side effects, caution should be exercised and medical advice sought for serious symptoms.
Grapefruit seed extract, a combination of grapefruit seeds and grapefruit pulp reduced to a highly acidic powder or liquid, has a wide variety of health benefits for humans. Whether ingested or applied topically, the extract is considered beneficial on several fronts. Grapefruit seed extract benefits include relief from bacterial and viral infections and quick healing of cuts and wounds. The extract is scientifically recognized as an antioxidant and an alkalizing agent. The extract is a staple of alternative medicine practitioners, but it is not considered a medicine, and sales are generally unregulated in any country.
The extract is an herbal remedy, as it is derived entirely from plant matter. If chemicals are introduced into the grapefruit seed extract, they are generally used only to hold the extract together, like in a capsule, and do not affect or alter the potency of the extract. Grapefruit seeds, and by extension its extract, contain very high concentrations of naringenin, a flavonoid. Flavonoids act as antioxidants, which means that they destroy harmful free radicals present in the body.
Most of the benefits of grapefruit seed extract derive directly from the rich flavonoid content of the seeds themselves. Academic studies and other sponsored scientific studies have shown that the extract is a disinfectant, an antibacterial agent and an antifungal agent in different concentrations. It promotes skin regeneration and can improve the healing time of cuts and wounds, and is generally believed to improve the health and function of the immune system. Grapefruit seed extract has also been shown to be an alkalizing agent, meaning it can help balance a person’s internal pH.
Much of how grapefruit seed extract benefits will be obtained depends on how concentrated the extract is to begin with and how much of the extract is consumed or applied. The benefits will also depend on how each person’s body responds individually. The concentrations of grapefruit seed extract used in scientific tests are not always the same concentrations or even the same preparations that are commonly marketed and sold as grapefruit seed extract supplements in stores.
Grapefruit seed extract is marketed by numerous health food stores and vendors around the world, usually under the name “GSE.” The range of claims between brands as to what GSE is capable of curing varies wildly. Some claim that grapefruit seed extract benefits have to do with diet, weight loss, and complexion. Others extol benefits ranging from a “miracle cancer cure” to a convenient way to get rid of a cold sore in a hurry. Still others market GSE as an antifungal foot rub, a cure for ear inflammation, a relief for gastrointestinal upsets, or a daily pill to prevent degenerative diseases.
There are no established side effects from consuming the extract, and in some sense the potential benefits of grapefruit seed extract outweigh the risk of not achieving the desired results. However, herbal remedies should not be taken without some precautions. No remedy, even one as potentially potent as grapefruit seed extract, can truly cure all ailments. It’s a good idea to talk to a doctor about any serious symptoms before using or ingesting grapefruit seed extract.
