Meticore is a weight loss supplement which claims to increase core body temperature thus increasing metabolism and weight loss.

In this article we’ll review the ingredients in Meticore based on medical research to determine if it’s likely to be effective. We’ll also highlight some practices this business engages in which we believe to be unethical and deceptive.

Formulation Review

Meticore doesn’t publish the ingredients in their product anywhere on their site. This alone should be a huge red flag to customers. We don’t recommend trusting brands that won’t even tell you what’s in their products. 

Not only is this almost certainly against FDA regulations for supplement companies, it’s just generally deceptive. It disallows consumers (and researchers like us) from determining if the product is likely to be safe and effective.

Thankfully, we were able to source the ingredients list from an image in an Amazon review of the bottle, which matched the ingredients list in a popular review of this supplement, so we can be almost sure these are the ingredients in Meticore: 

  • Vitamin B12
  • Chromium picolinate
  • 250 milligram (mg) proprietary blend containing turmeric, african mango seed, ginger, moringa leaf, citrus bioflavonoids and fucoxanthin.

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 can assume this is an ineffective ingredient.

As we discussed in our Plexus Slim review of another weight loss supplement, the mineral chromium is ineffective for weight loss, and is significantly underdosed in this product regardless. A medical study on chromium picolinate for weight loss found it ineffective even at a dose of 1000 mcg, which is 28x the dosage in Meticore.

The rest of this supplement is a proprietary (prop) blend, which is a deceptive practice manufacturers use to hide the individual ingredient doses. 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 likely to be 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 in turmeric) and weight loss used studies which nearly all contained dosages at or over 500 mg, which is double the entire dose of all ingredients in Meticore.

African mango seed may be effective for weight loss, but not at the dosage in Meticore. We identified two studies on african mango for weight loss that yielded favorable outcomes, but the doses were 350 mg and 150 mg. Since the average dosage of each ingredient in Meticore is 42 mg we can conclude this is underdosed and ineffective.

It’s also important to note that both studies used an extract of african mango seed, which is a more concentrated product than the raw botanical. Meticore just uses african mango seed, not extract, which makes it less likely to be effective based on medical research.

Ginger is another potentially-effective yet underdosed ingredient. A medical review of 14 different studies on ginger supplementation for weight loss found it to be effective, but the lowest dose used in any of the studies was 200 mg and most studies used around 1000 mg. Since the average ingredient dose in Meticore is 42 mg, we can conclude this ingredient should be ineffective.

Moringa leaf is the fourth-listed prop blend ingredient in Meticore, and it again appears they used the wrong version. Moringa leaf extract has been shown in two animal studies (1, 2) to have anti-obesity effects, but again the extract is more potent than the raw powder, which isn’t proven to be effective.

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 factors higher than the relative dose of bioflavonoids a human would get from Meticore, and so we can conclude again that this ingredient should be ineffective.

Fucoxanthin is a chemical derived from brown algae. We can only locate one human study on its weight loss effect. While the study did show an antiobesity effect, 300 mg of pomegranate seed oil was also used so the effect can’t be ascribed to fucoxanthin alone.

Overall we find this to be a poorly formulated supplement for weight loss. While some of the ingredients have been tested for weight loss in medical studies, Meticore often uses an ineffective dose or an ineffective form of the active ingredient.

Misleading and Dangerous Health Claims

Meticore’s site contains several misleading and dangerous health claims. They claim their product is “safer than your daily multivitamin”. That is absolutely untrue, as they have neither funded scientific studies on their product nor published any testing data proving their product is accurately labeled and free of contaminants like heavy metals or pesticides.

Multivitamins, on the other hand, have been studied extensively and are conclusively safe for long-term use. We don’t recommend them for most people because there is no benefit unless you have a nutrient deficiency, but there is much more clinical research proving multivitamins are safer than Meticore.

Meticore also claims 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”.

This, again, is totally untrue. There are no doctors researching this product, as there is no published clinical research on Meticore at all. This is just a blatant type of false advertising to influence consumers to purchase more products.

Misleading Medical Logos

Meticore misleading logos

Meticore’s website highlights logos from various medical institutions right under their product pictures, suggesting their products are recommended by these institutions which is totally untrue. 

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 it has studied Vitamin C. It’s a totally unrelated organization. 

What Meticore seems to be doing here is a very blatant type of false advertising and copyright infringement which we don’t agree with ethically, and which should prompt educated consumers to avoid the brand altogether.

Meticore is a poorly formulated supplement, and we don’t believe it will be effective at all for weight loss due to the underdosed ingredients in its formulation.

We believe taking Meticore is a risk to your health based on how actively deceptive the company is, and how they fail to publish any medical research proving the efficacy or safety of their products.

There is no publicly listed team behind this product, which is a huge red flag in and of itself.

We recommend that consumers avoid this brand entirely.
