PhenGold Review: Does the "Natural" Fat Burner Work?

PhenGold Review: Does the "Natural" Fat Burner Work?

| |
| |

PhenGold is a weight loss supplement manufactured by a brand called Health Nutrition Limited. The brand claims that their supplement “enhances your body’s natural fat-burning abilities” and “reduces cravings” with their “clinically proven ingredients.”

But does PhenGold actually have research-backed ingredients for weight loss, or are these just marketing claims? Does the supplement contain any questionable additive ingredients? And how do real users rate and describe its effects?

In this article we’ll answer all of these questions and more as we review the ingredients in PhenGold based on medical research to give our take on whether the supplement is likely to be effective for weight loss or if it’s a waste of money.

We’ll also publish our thoughts on whether or not PhenGold is likely to cause side effects, highlight some questionable health claims made by the brand, and share real, unsponsored user reviews of PhenGold

Ingredient Analysis

PhenGold Supplement Facts label

PhenGold contains 11 active ingredients, and some do have research backing for weight loss.

Green tea was shown in a 2012 meta-study to modest weight loss ranging from 0.4 pounds to 7.7 pounds over the course of 12 weeks. The dose in PhenGold is equivalent to the doses used in the lower range of the clinical trials analyzed, so we would expect any weight loss effect to be closer to 0.4 pounds than 7.7 pounds.

Caffeine intake is also associated with weight loss, and the 225 milligrams (mg) in PhenGold is an effective dose. It’s equivalent to slightly more than two cups of coffee.

A medical review published in the Critical Reviews in Food Science and Nutrition journal found that caffeine causes weight loss and fat loss.

Green coffee may be effective for weight loss. As we documented in our review of another weight loss supplement called Truvy, clinical trials have shown this ingredient to have a dose-dependent effect on weight loss, and the 4:1 extract at a 100 mg dose is effectively dosed.

We can’t identify any other ingredients in this supplement that we consider effective for weight loss.

Cayenne pepper is included at what seems to be a strangely low dose of 200 mg. This is 9x less than the amount in one single teaspoon of cayenne pepper, according to the USDA.

Overall we consider PhenGold to be potentially effective for weight loss given that it contains three research-backed ingredients which appear to be effectively dosed.

We don’t recommend the supplement overall. Since only three of the 11 ingredients are effectively dosed for weight loss based on our research review, we don’t believe it’s worth $59.99. That being said, it is a better formulation than the majority of weight loss supplements we’ve reviewed on Illuminate Health.

Questionable Health Claims on PhenGold Website

PhenGold questionable health claim 1

There are a number of questionable health claims on the PhenGold website, including the chart above which has no citation. PhenGold does not appear to have been studied in any clinical trials, so what data is the manufacturer using to create this chart?

If this chart is just made up for illustrative purposes, with no data backing, that would be confusing and unfair to consumers. We hope that the brand clarifies this.

The brand also makes strange claims about some of the ingredients in their supplement.

PhenGold questionable health claim 2

They claim that the plant Rhodiola rosea burns fat. We have not come across any medical studies suggesting that this plant causes fat loss, and the citation that the brand links to has nothing to do with fat loss – it suggests that rhodiola can reduce feelings of weakness.

PhenGold questionable health claim 3

The manufacturer also claims that l-theanine, which is an amino acid typically taken for stress reduction, “boosts metabolism.” 

PhenGold questionable health claim 4

We haven’t come across any clinical evidence of this effect, and there are no citations on their website that prove it.

Will PhenGold Cause Side Effects?

Since PhenGold has not been studied in any clinical trials, it’s impossible to determine for certain whether or not it causes side effects. However, we can make an educated guess based on its active ingredients.

Caffeine is the only ingredient in this formulation we consider to have a chance to cause side effects. It’s included at a safe dose for healthy adults, but individuals sensitive to caffeine may experience side effects like anxiety from a 225 mg dose, and those individuals should probably avoid this supplement.

There are no other ingredients in this formulation that we consider likely to have side effects, and there are no ingredients overall that we consider a health risk. It’s also a good thing that the inactive ingredients are entirely safe and non-toxic.

Overall we do not consider PhenGold likely to cause side effects in most consumers.

Real, Unsponsored PhenGold User Review

A YouTube channel called “Total Shape” published a video on PhenGold that includes a review of the ingredients and their personal experience taking the supplement. The packaging has been since rebranded but this is the same supplement we’ve reviewed in this article:

Our Clean Weight Loss Picks

There are food-based nutrients which have been shown in medical studies to be effective for weight loss.

Dietary fiber was shown in a medical review published in The Journal of Nutrition to cause 16 pounds of weight loss in 6 months when combined with moderate caloric restriction (750 calories per day below baseline).

MBG Organic Fiber Potency+ is our top fiber pick because it's certified organic, provides 7 g of fiber per serving and costs under $1.85 per serving at the time of updating this article.

MCT oil was shown in a meta-study to cause more than one pound of weight loss over 10 weeks. This equates to potential annualized weight loss of 6 pounds per year with less than one tablespoon's worth of MCT oil per day.

Bulletproof MCT Oil is our top MCT oil product, because the only ingredient is MCT oil derived from coconuts. and it currently costs only $15.50 for over a month's worth of product.

Ginger intake "significantly decreased body weight" according to a 2019 meta-study on ginger and weight loss that analyzed data from 14 clinical trials.

Pique La Ginger is our top ginger product, because it's an organic tea in convenient crystallized form, and all that's needed is to pour the powder into a glass and add hot water.

All three of the products mentioned in this section are entirely free of additive ingredients that we consider to be unhealthy or unsafe.

Where to Buy PhenGold for the Best Price

PhenGold is currently sold at Amazon and the brand's website. Here's a price breakdown for a one-time purchase at the time of updating this article:

Amazon: $69.99 (free shipping, link to Amazon listing)

Brand website: $64.99 (free shipping, link)

PhenGold is currently 7% cheaper on Amazon than on the brand's website, and the Amazon listing is from a third-party seller, so the brand's website may be the safest purchase option.

Stay up-to-date on our research reviews


PhenGold may be effective for weight loss because it contains several research-backed ingredients at appropriate doses. It’s free of any harmful or questionable ingredients which is a good sign.

We do not recommend this supplement overall as we don’t consider it to be a cost-effective way to achieve weight loss, but we don’t have any issues with consumers taking it.

For those interested in trying PhenGold, you’ll need to purchase it on the official brand’s website because the supplement is not currently sold on third-party retailers like Amazon or Walmart.

There are a number of questionable and uncited health claims on the PhenGold website, and we hope that the brand either removes these claims or updates them to include proof.

We do not believe that PhenGold is likely to cause side effects except for in consumers sensitive to caffeine.
