Fungus Eliminator Review: Can Pills Cure Toenail Fungus?

Fungus Eliminator Review: Can Pills Cure Toenail Fungus?

| |
| |

Fungus Eliminator is a dietary supplement sold by a brand called PureHealth Research. It's an oral supplement that's used to treat toenail fungus, and the manufacturer claims that each ingredient is "scientifically proven to combat unsightly toenail fungus deep in your nailbed where topicals can't reach."

But does Fungus Eliminator actually contain research-backed ingredients or are these just marketing claims? Does the supplement contain any questionable additive ingredients? Does it even make sense to take oral supplements for toenail fungus? And how do real users rate and describe the effects of Fungus Eliminator?

In this article we’ll answer all of these questions and more as we review the ingredients in Fungus Eliminator based on medical studies to give our take on whether or not the supplement is likely to be effective.

We'll also highlight some questionable health claims made by the brand, analyze whether it makes sense to take oral supplements for foot fungus based on medical research, and share real, unsponsored user reviews of this product.

Ingredient Analysis

Fungus Eliminator ingredients

Fungus Eliminator contains nine active ingredients, the majority of which are herbs and spices that can be found in a grocery store.

Oregano is a culinary herb included at a dose of 300 milligrams (mg). While there is published medical research on the antifungal effects of oregano essential oil, we cannot locate any medical studies suggesting that the raw herb is effective.

Garlic is an effective antifungal ingredient, but may be underdosed in Fungus Eliminator at a dose of only 100 mg.

A medical review on the therapeutic effects of garlic analyzed data from 110 clinical trials on the topic. The lowest dose used in any of the cited trials was 200 mg, and many of the trials used far higher doses.

To illustrate how low some of the dosages in this supplement are, this educational resource lists the dose of one single teaspoon of dried oregano at over 1,000 mg. This means that one teaspoon of dried oregano is over 300% of the dose of the highest-dose active ingredient in Fungus Eliminator.

We are unable to identify any medical evidence that the ingredients in this supplement, at their included doses, are effective for treating toenail fungus when taken orally. 

The brand does not cite any medical studies proving their supplement works, or that its ingredients are effectively dosed, on its product page.

The inactive ingredients are safe and non-toxic, so at least there are no questionable additive ingredients or any ingredients in this formulation that we consider a health risk.

Highly Questionable Health Claims on Website

Fungus Eliminator questionable health claim 1

There are a number of strange health claims on the Fungus Eliminator website. The brand claims, without any proof or citation, that caprylic acid can destroy fungus "in minutes."

Caprylic acid is a medium-chain fatty acid derived primarily from coconut which does have some anti-fungal effects. However, we have not come across any medical research suggesting it works in minutes when taken orally, nor have we come across any medical research suggesting it works at the dose included in this supplement.

Fungus Eliminator questionable health claim 2

PureHealth Research also claims on the product page that “ingredients in Fungus Eliminator have no reports of side effects,” which seems to be demonstrably untrue.

A medical review of wormwood, one of the ingredients in Fungus Eliminator, has an entire section dedicated to side effects of this botanical compound.

The study authors state the following: “long-term administration of [wormwood] leads to some neurotoxic effect due to the presence of thujone and its analogues."

We hope that PureHealth Research updates their website and provides proof of these health claims or removes them.

How Do You Prevent Toenail Fungus?

So far in this article we've discussed potential ways to treat toenail fungus, but even once it's treated it's important to take steps to prevent it from reoccuring and from suffering again.

Our Clean Antifungal Picks

There are some natural products with promising early research for treating fungus.

Medium chain triglyceride (MCT) oil was shown in a clinical trial published in the Nutrients journal to be an effective oral antifungal:

"MCT holds promise as a therapeutic intervention for reducing fungal colonization without significant impact on the bacterial composition of the host gastrointestinal tract."

Bulletproof MCT Oil is our top MCT oil pick, because its only ingredient is MCT oil derived from coconuts and it has zero additives. It currently retails for under $16.

Coconut oil may be an effective topical antifungal agent, as a 2007 medical review concluded that "Coconut oil should be used in the treatment of fungal infections in view of emerging drug-resistant Candida species."

Dr. Bronner's Organic Coconut Oil is our top coconut oil pick, as it's packaged in glass, virgin (meaning it's not heat-treated), and has no questionable additive ingredients. The only ingredient is organic coconut oil.

We're not suggesting that either of these products should be used to treat any disease or health condition; just sharing promising research on two natural compounds that individuals may wish to speak with their doctor or dermatologist about.

The top positive review of Fungus Eliminator from a verified purchaser is written by a user named “Nikki G” who claims the product cured their toenail fungus:

“Have had fungus on big toenails for years. Tried everything from vapor rub, listerene mouthwash soaks, vinegar soaks, and over the counter meds and tonics to apply to toenails… nothing worked. Don’t want to take a prescription med that I have to go have my liver or kidneys tested for every few weeks… too busy for that. Been taking for 2 months… not solved or perfect but a noticeable difference. Worth the money.”

The top negative review from a verified purchaser is written by a user named “Steve Barbre” who claims the product didn’t work:

“Good ingrediance but not string enough maybe”

Stay up-to-date on our research reviews


We do not recommend Fungus Eliminator. While the supplement does contain some active ingredients shown in clinical trials to have an antifungal effect, we cannot identify any ingredients that are dosed effectively based on clinical research.

We also can't identify any medical research suggesting that natural oral supplements are effective for treating toenail fungus. The only research we could find on oral treatments for toenail fungus involved prescription antifungals.

PureHealth Research makes a number of questionable and uncited health claims on their website, including that one of the ingredients in Fungus Eliminator destroys fungus "within minutes."

For consumers intent on purchasing Fungus Eliminator, it's currently much cheaper on Amazon than on the manufacturer's website.
