MetSlim Pro: Review the Met Slim Pro Weight Loss Diet Pills

MetSlim Pro, or Met Slim Pro, is a healthy weight loss supplement by James Carr that utilizes natural plant-based vitamins and minerals to help burn belly fat effectively and safely without side effects.


MetSlim Pro is a diet pill that claims to help with weight loss.

By taking MetSlim Pro daily, you can purportedly enjoy powerful weight loss results with limited hard work, exercise, or dieting. The supplement uses ingredients like vitamin E and green tea extract to kickstart your body’s natural weight loss processes.

Obviously, many diet pills make similar claims – and many of them don’t work as advertised. Let’s take a closer look at how MetSlim Pro works to see if it’s the right weight loss aid for you.


What is MetSlim Pro?

MetSlim Pro is a diet pill sold exclusively online through

The diet pill uses herbal extracts, vitamins, and minerals to help you lose weight. You take two capsules of MetSlim Pro daily, then lose weight without significantly changing your diet or exercise habits, according to the official website.

MetSlim Pro is marketed online by a man named James Carr, a weight loss researcher with decades of experience. James used that experience to create MetSlim Pro, and now he wants to share his formula with the world.

Obviously, all diet pills make similar claims – so let’s take a closer look at how MetSlim Pro works.

How Does MetSlim Pro Work?

The makers of MetSlim Pro provide limited information about how the formula works or what the formula does. The supplement claims to use various vitamins and minerals to lose weight – similar to the vitamins and minerals found in any multivitamin supplement.

MetSlim Pro also contains ingredients you won’t find in an average multivitamin, including cat’s claw, green tea extract, stinging nettle, and mushroom extracts (including reishi, shiitake, and maitake mushroom extract).

These ingredients are similar to what we see in other weight loss aids available today. Many of these supplements contain vitamins and minerals mixed with herbal extracts. You take the supplement daily, then lose a significant amount of weight with no changes to your diet or exercise.

Based on the ingredients listed, MetSlim Pro seems like a combination of a detoxification formula and a weight loss aid: most diet pills contain thermogenics (like caffeine) or appetite suppressants (like fiber). MetSlim Pro simply contains herbal extracts that encourage your body to release toxins. These ingredients could help you lose weight, but they work differently than a typical diet pill.

However, the makers of MetSlim Pro claim the supplement doesn’t specifically target weight loss or detoxification: it targets the thyroid, which is the root cause of your weight problems. It’s unclear how MetSlim Pro targets the thyroid or what it does, but the company claims the formula will impact your thyroid in some way.

Without knowing the full list of ingredients or dosages in MetSlim Pro, it’s hard to compare the formula to other diet pills.

Overall, there’s limited information online about how MetSlim Pro works, what’s in the formula, or why it’s better than other diet pills or multivitamins sold online today for a fraction of the price.

The Story Behind MetSlim Pro

As part of a 2020 marketing campaign, the makers of MetSlim Pro share the story of a man named James Carr.

James is a 57-year old man living near Austin, Texas with his wife, Daisy. James has years of experience researching weight loss solutions. Now, nearing the end of his career, James wants to share those solutions with the world.

In a sales page and video, James shares tips for losing weight, then recommends taking MetSlim Pro to accelerate weight loss results.

James has a personal reason for marketing MetSlim Pro, claiming he witnessed significant weight loss results from the formula.

James claims he formulated MetSlim Pro based on strict requirements. He designed the supplement to help anyone lose weight, claiming it’s 100% effective and clinically proven to work as advertised.

MetSlim Pro Ingredients

Let’s take a closer look at the ingredients in MetSlim Pro to see what James Carr created:

Green tea extract

Stinging nettle extract

Mushroom extract (maitake, reishi, and shiitake)

Cat’s claw extract

Vitamin E, vitamin B6, zinc, and selenium

You can get green tea extract and vitamins and minerals from ordinary supplements – including multivitamins or green tea.

However, the other ingredients in MetSlim Pro are more unique, including stinging nettle extract and cat’s claw extract. These plant-based ingredients have been used in traditional medicine for centuries to support various health and wellness benefits.

Unfortunately, MetSlim Pro does not disclose its ingredients label upfront, nor does it list specific dosages of any ingredients. We know MetSlim Pro contains some of the ingredients listed above, but it’s unclear if it contains more ingredients – or at what dosages.

Next, we’ll review the science behind these ingredients.

Scientific Evidence for MetSlim Pro

MetSlim Pro has not completed any clinical trials or scientific studies to verify it helps with weight loss. It’s unclear if the formula is safe or effective, as it has not been tested on any humans or animals.

However, that’s not unusual for nutritional supplements, as most companies don’t invest in clinical testing.

Fortunately, individual ingredients in MetSlim Pro have been tested in various weight loss studies. Some studies show these ingredients could help with weight loss, while others show they’re no better than a placebo.

First, stinging nettle is frequently found in herbal detoxification supplements. People have used stinging nettle for centuries to detoxify the body. Today, some diet pills use stinging nettle to block fat, and Men’s Health even recommends eating nettle soup to lose weight more easily. Most studies suggest using a dosage of 400mg of stinging nettle extract or higher to block fat and lose weight, although there’s limited research overall verifying the weight loss benefits of stinging nettle.

Many people weight loss supplements contain green tea. Green tea is a common fat burner that contains a small, natural dosage of caffeine (typically about 5% to 10% of the caffeine dosage, or less, of an average cup of coffee). Green tea extract is also rich with EGCG, antioxidant-rich compounds that could support healthy inflammation throughout the body.

Some studies have shown green tea has genuine weight loss benefits. This 2014 study published in the Canadian Pharmacists Journal analyzed 14 trials on green tea and weight loss with a total of 1,500+ participants. After analyzing all this evidence, researchers found that the green tea group lost an average of 0.2 to 3.5kg (0.4 to 7.8lbs) more than a placebo, although researchers did not find this different significant.

Similarly, this 2009 study showed that the EGCG and caffeine in green tea “have a small positive effect” on weight loss and weight maintenance.

The mushroom extracts in MetSlim Pro are not commonly found in diet pills. Mushroom extracts are typically used as adaptogens, which means they help your body manage stress. It’s possible the maitake, reishi, and shiitake mushroom extracts in MetSlim Pro help support stress in your body, indirectly helping with weight loss. However, without knowing individual dosages, it’s hard to verify these benefits.

The final ingredient in MetSlim Pro is cat’s claw extract. Cat’s claw is a woody vine that can purportedly support inflammation and detoxify the body. There’s limited specific evidence cat’s claw leads to significant weight loss, although it should be safe to use and could provide small support for various body processes.

The other ingredients in MetSlim Pro, including vitamin E and selenium, could help with various body processes, although the doses seem too low to significantly impact the body. You’re better off getting these ingredients from an ordinary multivitamin.

Overall, MetSlim Pro contains average to low dosages of a small number of common diet pill ingredients. The green tea extract, vitamins, and minerals are the most scientifically proven ingredients within MetSlim Pro, and you can find these ingredients in many cheaper formulas.
