AVG Rating: 3.5/10

You need to stay informed of the product being sold out there for weight loss. That’s because if you’re looking for an extra edge in losing weight, supplements might seem tempting – but if you go in without knowing enough about them, you might end up wasting money. Worse, you might end up endangering your health. That’s why we’ve assembled these reviews of weight loss products, to make sure you’re up to speed on the latest in diet pills and supplements.

These are the Top 10 most-recommended pills that can help you with weight loss.

Instant Knockout Overview

Instant Knockout is a weight loss supplement that’s meant to help you burn fat for a leaner physique. It comes in bottles of 120 capsules, which may sound like a lot, but since you have to take 4 pills a day (according to the company) you’re only getting one month of use out of a bottle. Each bottle costs $60, but if you purchase more than one at a time, there are discounts offered. The company offers a 90-day guarantee on this product, and they ship worldwide.

Instant Knockout is made by Roar Ambition, a nutritional supplement company based in the UK. This company makes grand claims about their business, but according to customer reviews, they appear to be a nightmare to work with. Customers said they had difficulties making returns, and that the company specifically tried to stall for time and reject claims for refunds. Others have complained about the customer service, leading us to believe that this company may be problematic to deal with.

Check out these Top 10 pills that can help you with your weight loss journey.

Instant Knockout Claims

Instant Knockout is supposed to do three main things. First, it’s supposed to increase your energy levels, making you able to power through your workouts.

Second, it’s supposed to make your body burn fat by “turning off” a receptor in your body that causes fat to accumulate. Third, it’s supposed to work as an appetite suppressant, filling you up so that you aren’t hungry enough to overeat, allowing you to lose weight faster.

Here’s our list of the best new weight loss pills on the market.

Instant Knockout Ingredients

Instant Knockout’s ingredients include the following:

  • Pyroxidine
  • Cyanocobalamin
  • Chromium
  • Green Tea Extract
  • Caffeine
  • Glucomannan
  • Cayenne

Chromium is a mineral that helps the body to move blood sugar into the cells, where the sugar is used for energy. Green Tea extract is made from the green tea leaf, and according to Instant Knockout, can “turn off” the receptor involved in fat accumulation. However, it’s also dangerous, and has been associated with heart and liver problems in certain doses, as well as side effects like diarrhea and vomiting (WebMD).

Caffeine is a stimulant used for energy. Glucomannan is made from the konjac root, used as an appetite suppressant. It’s also associated with being a choking hazard, since it can expand while still in the throat (Health Canada).

The Science Behind Instant Knockout

This product claims that the green tea extract “tells” your body to stop accumulating fat, that the caffeine gives you the energy to be active, and the glucomannan keeps you from being hungry, suppressing the appetite.

While caffeine is well-known to be a popular stimulant that can give you energy, there’s “insufficient evidence” that green tea extract has any effect on obesity and weight loss, unfortunately (WebMD). Glucomannan has been shown in trials to show “no significant difference” in helping people lose weight compared to placebo (Keithley, J et al: “Safety and Efficacy…” J Obes, 2024).

Word on the Street About Instant Knockout

You need to make sure you have an unbiased source of customer reviews when you’re considering a product, but unfortunately, we couldn’t find any customer reviews from any legit third-party source. The only customer reviews we found were from their own website, which of course only provides positive feedback from users.

We also don’t know how legit these reviews are, what the circumstances of their testimonials were (if they’d been reimbursed, paid, or given free product), or if they’re affiliated with the company somehow, leading to a conflict of interest.

Out of all the diet pills we’ve looked at, these are the best.

Is Instant Knockout Worth Trying?

We would say no. For one thing, the company has lots of bad customer experiences associated with them, leading us to worry that they don’t take customer satisfaction seriously. The product also contains ingredients that either have no clinical proof of working (glucomannan) or have been associated with severe health problems and uncomfortable side effects (green tea leaf extract). Lastly, problem is that you can only find the product – and customer “reviews” – on the main website, meaning there’s no third-party source of reviews about the product, making it less trustworthy.

We recommend skipping Instant Knockout in favor of better products.

The best pills for helping you with losing weight are all on this easy list.

Instant Knockout vs LeanBean

These products are fairly similar, but have notable differences. Both of them claim to help users burn extra fat as a part of a weight-loss regimen. Instant Knockout seems to be aimed at both men and women, while LeanBean is aimed exclusively at women. Both contain glucomannan, chromium, and green tea extract, but LeanBean has extra ingredients like garcinia cambogia and raspberry ketones. Both of them cost the same – for a one month supply.

Instant Knockout vs Hydroxycut

These pills both claim to help you burn fat and lose weight quicker than when using other (or no) products. Both contain caffeine as stimulants, but Instant Knockout contains green tea extract and glucomanna, while Hydroxycut contains more fruit and vegetable extracts as a part of its formula. As with the previous product, these pills both cost the same: around $60 (not including shipping) for a one-month supply.

Instant Knockout vs Blade

Both of these product claim to help you burn fat, but in different ways. Instant Knockout claims to prevent fat accumulation by affecting the “Alpha-2 receptor,” while Blade claims to induce the release of norepinephrine, a hormone associated with fat burning. Both contain caffeine, but Blade contains yohimbe, a notorious stimulant that’s associated with heart problems, as well as bitter orange (which can also cause heart problems).
