Meticore is a dietary supplement which claims to cause weight loss by increasing core body temperature.
In this article we’ll review every ingredient in Meticore based on medical research to give our take on whether the supplement is likely to be effective for weight loss. We’ll also highlight some questionable marketing practices the company engages in, and explain why we don't recommend buying Meticore on Amazon.
There are several weight loss supplements selling a product called "Meticore" and it's unclear if there is one official manufacturer. The ingredient list shown above is the only Meticore ingredient list we could access from any of the retailers. Many of the Meticore websites and Amazon listings failed to publish an ingredient list.
We do not consider Vitamin B12 to be an effective weight loss ingredient. While Vitamin B12 deficiencies are associated with obesity in medical research, we haven’t seen a single study suggesting that its supplementation directly causes weight loss, so we will consider this to be an ineffective ingredient.
As we discussed in our Plexus Slim review of another weight loss supplement, we consider the mineral chromium to be ineffective for weight loss, and we believe it's significantly underdosed in this formulation regardless. A 2010 clinical trial on chromium for weight loss found it ineffective even at a dose of 1000 micrograms (mcg), which is 28x the dosage in Meticore.
The rest of this supplement is a proprietary (prop) blend called the "Meticore Formula Blend." We disagree with the use of prop blends and recommend that consumers avoid supplements listing ingredients in this manner.
Listing the ingredients as a prop blend allows companies to list only the total dose but not the individual dose of the ingredients contained in the blend, making it harder for consumers and researchers to determine if each ingredient is effectively dosed.
Turmeric may be effective as a weight loss supplement, but is almost certainly underdosed in this product because a medical review of curcumin (the active chemical compound in turmeric) and weight loss analyzed studies which nearly all contained dosages at or over 500 milligrams (mg), which is double the dose of every ingredient in Meticore combined.
African mango seed may be effective for weight loss, but we consider it underdosed in Meticore. We identified two studies on African mango seed for weight loss that yielded favorable outcomes, but the doses were 350 mg and 150 mg, respectively. Since the average dosage of each ingredient in Meticore's prop blend is only 42 mg we will consider this ingredient ineffective.
It’s also important to note that both studies above used an extract of African mango seed, which is more potent than the raw African mango seed in Meticore.
Ginger is another good ingredient choice that we find to be underdosed in this formulation. A medical review of 14 clinical trials on ginger supplementation for weight loss found it to be effective, but the lowest dose used in any of the trials was 200 mg and most trials used closer to 1,000 mg. Since the average ingredient dose in Meticore's prop blend is 42 mg, we will consider this ingredient underdosed and ineffective.
Moringa leaf is the fourth-listed prop blend ingredient in Meticore, and again the brand uses the raw botanical ingredient rather than a more potent extract version. Moringa leaf extract has been shown in two animal studies (1, 2) to have anti-obesity effects, but we can't identify any medical research suggesting that raw moringa leaf (what's in Meticore) is effective for weight loss.
Citrus bioflavonoids were found to be effective for weight loss in one animal study, but the animals consumed diets with two separate bioflavonoids at 0.3% and 3% of their diet by weight. This is many times higher than the relative dose of bioflavonoids a human would get from Meticore, and so we will again consider this ingredient underdosed and ineffective.
Fucoxanthin is an ingredient derived from brown algae. We can only locate one human study on its weight loss effect. While the study did show an anti-obesity effect, 300 mg of pomegranate seed oil was also used so the effect can’t be ascribed to fucoxanthin alone.
This Meticore formulation is free of any harmful inactive ingredients like artificial color, flavoring or titanium dioxide which is a good thing.
Overall we find this to be an underwhelming formulation, and we don't believe it will be effective for weight loss. While many of the ingredients have some medical research backing for weight loss, we cannot identify one single ingredient that we consider effectively dosed.
Questionable Health Claims
At the time of initially writing this article, Meticore’s site had several health claims that we strongly disagreed with. The website claimed that Meticore was “safer than your daily multivitamin” without any medical citation.
Multivitamins have been studied extensively and are conclusively safe for long-term use. We don’t recommend their use, but we found this statement to be highly questionable given that Meticore has never been studied in a legitimate clinical trial published in a medical journal.
The website also claimed that “doctors researching these natural ingredients recommend you take Meticore for at least 90 days to 180 days to ensure you reach your desired weight”.
There was no reference to which doctors were making these claims, and we found this statement to be misleading.
It appears that Meticore has since updated the language on their website, possibly due to our comments. The first statement has been removed, and the second statement has been changed to a more standard marketing claim that we take no issue with:
"For optimal results, consumers should take the pills regularly for at least 90-180 days."
There are still health claims we disagree with on the Meticore site, such as the uncited claim that low body temperature is the root cause of slow metabolism. We have not seen any medical evidence of this.
Questionable Marketing Practices
Meticore’s website highlights logos from various medical institutions right under their product pictures, which indirectly suggests that these institutions recommend their supplement. We very strongly disagree with this marketing practice, and find it to be misleading.
The logos of the National Center for Biotechnology Information (NCBI), International Journal of Obesity, American Clinical Laboratory Association (ACLA), and the Journal of Applied Physiology are shown.
It’s unclear why these associations were selected, but it’s likely because some of the ingredients used in Meticore were referenced by these associations. That does not infer a recommendation of Meticore by any of these associations.
If a supplement company uses Vitamin C in their formulations, it doesn't mean they can claim that the Council for Responsible Nutrition backs their product just because that organization has studied Vitamin C.
We believe that the Federal Trade Commission (FTC) should look into this practice for potential false advertising.
Our Weight Loss Supplement Recommendations
We recommend the food product dietary fiber as a safe and effective weight loss supplement.
An extensive medical review published in The Journal of Nutrition found that dietary fiber intake directly predicts weight loss when consumed at a high enough dose. It's zero-calorie plant matter that makes you feel full faster, and consume fewer calories overall.
The fiber supplement we recommend is SuperGut Fiber Mix. It contains a clean and effective formulation: a blend of three different types of unflavored dietary fiber and zero additive ingredients. It can be mixed into liquids or foods. Interested consumers can buy SuperGut fiber at this link.
We recommend using two fiber mixes per day, which provides 16 g of fiber. This is within the effective fiber dosing range associated with the greatest weight loss outcomes in the above-linked study (8-29 additional grams per day).
Medium-chain triglyceride (MCT) oil is another dietary supplement which has been shown in clinical trials to cause weight loss.
MCT oil is quickly absorbed by the body and increases metabolic rate, which causes fat loss. A meta-study on MCT oil documented average weight loss of 0.51 kilograms (kg), which equates to 1.12 pounds (lbs). The trials lasted 10 weeks on average. This equates to a potential annualized weight loss of 5.84 pounds with MCT oil supplementation.
We recommend Bulletproof MCT Oil as our top MCT oil product, because it has a clean and effective formulation. The only ingredient is MCT oil derived from coconuts, and the product has no questionable additives. Interested consumers can buy Bulletproof MCT Oil at this link.
The effective dose range of MCT oil for weight loss (based on the medical review) is 1.7 g to 10 g per day. Bulletproof's MCT oil provides 14 g in one tablespoon, so around two-thirds of one tablespoon should be a maximally-effective dosage.
Avoid Meticore on Amazon
For consumers intent on purchasing Meticore, we would recommend purchasing directly from the manufacturer's website (which we don't want to link here because we do not support their business) as opposed to purchasing on Amazon.
As referenced in the intro to this article, there are many different Meticore products available on Amazon, and none of the ones we examined published an ingredient list. It's highly unsafe to purchase a dietary supplement without an ingredient list.
What appears to be the official Meticore manufacturer website has the ingredient list we shared above, and which we analyzed in this review.
Purchasing from the official manufacturer will allow consumers to know what ingredients are in the product they're buying.
