From our initial summary, it’s plain to see that both products have similarities.

They both claim to help support you on your journey as you look to hit your goals.

Leanbean has been endorsed by famous sportswomen such as Bree Kleintop, while Instant Knockout boasts of testimonials from Pro Athletes like MMA Fighter Diego Sanchez and World-Class MMA Coach Greg Jackson.

One big difference between the two is the caffeine content, Instant Knockout contains 350mg of Caffeine Anhydrous, a pretty strong form of caffeine.

The Bottom Line: Besides being formulated for different genders, both Leanbean and Instant Knockout are similar in many ways. Both products are manufactured by reputable companies, use good ingredients, and most importantly, they do not use proprietary blends.

For this round it’s a tie.

The Servings

For consistent results, choosing a supplement that provides adequate servings is crucial.

Some cheap products only provide one or two servings per day. Generally speaking, one or two servings simply aren’t enough to supercharge your results.

The best supplements usually provide at least 4 servings per day, as spreading out the servings supplies your body with consistent supplementation throughout the day.

Thankfully both Leanbean and Instant Knockout provide 4 servings per day. At $59 this ensures you are getting great value for money and a full 120 capsules per month.

Bottom Line: Both supplements offer adequate servings, something that many cheaper products in the market lack. For this round, it’s also hard to pick between the two. Both have emerged as winners when it comes to servings.

Ingredients and Dosages

When it comes to any supplement, it’s not about the quantity of ingredients – it’s about the quality and effectiveness of the natural compounds themselves.

Let’s look at the ingredients labels of both products.

The Leanbean Ingredients label

A look at the ingredients labels of both supplements and it is notable that both have avoided proprietary blends.

We never like proprietary blends as it’s a trick that manufacturer’s use to hide the actual dosages of the ingredients. With proprietary blends, it’s hard to determine whether a product is overdosed, under-dosed, or whether it’s just a cheap formula with barely anything in it at all.

Fortunately, these two supplements list everything transparently.

As you can see, the ingredients in both supplements are pretty good.

Instant Knockout uses a couple of ingredients like Glucomannan and Caffeine Anhydrous in larger doses, whilst Leanbean includes some added extras not found in its rival, including Turmeric and Garcinia Cambogia.

The shared ingredients include:

• Glucomannan
• Green Tea Extract
• Cayenne Pepper
• Green Coffee Bean Extract
• Chromium
• Black Pepper Extract (Bioperine)
• Vitamins B6 and B12

Leanbean contains some important ingredients such as Chromium and Glucomannan, as well as some key B Vitamins.

Instant Knockout is packed with caffeine anhydrous and zinc, both of which are missing in Leanbean.

The Bottom Line: Both supplements contain some of the best and most effective ingredients out there. Reviewing them closely, Leanbean has a strong focus on female-friendly ingredients, whilst Instant Knockout uses a hard-hitting stimulant approach.

Potential Side Effects

Both Instant Knockout and Leanbean contain Caffeine. However, because bodybuilders typically tolerate caffeine in high doses, Instant Knockout packs a whopping 350g of Caffeine Anhydrous. For some women, this may well be slightly too much.

Leanbean, on the other hand, contains a smaller amount of natural caffeine from Green Tea Extract and Green Coffee.

The Bottom Line: If you are sensitive to stimulants then Leanbean might be a good choice for you.

Instant Knockout vs Leanbean – The Prices

Finally, which supplement provides better value for money?

As with any product out there, you get what you pay for. Given both products are made in similar facilities and use a high-quality standardized ingredients it is no surprise that they are priced similarly.

The Leanbean pills are currently priced at $59 and are available for purchase at the manufacturer’s website.

Instant Knockout is also currently being sold at $59 for a full month’s supply and is only sold direct as well.

So, if you’re looking to buy Leanbean or Instant Knockout on GNC, Amazon, or other third-party sellers, you might want to think twice as the products you find there are unlikely to be genuine.

Both products offer an extra bottle for every 3 bottles purchased, not to mention free delivery and a 90-Day Money Back Guarantee. Leanbean includes a free workout guide too.

The Bottom Line: Given the quality of their formulas, we can confidently say that both Leanbean and Instant Knockout offer solid value for money.
