Before starting any type of dietary supplement, you should consult with your health care professional to go over the ingredients.  This way you can be sure there will be no allergic reactions, and you want to be sure that it won’t interact with any medications that you may be taking on a regular daily basis. 

The ingredients as a whole in Instant Knockout may be natural and safe in general, but individually they could have a slight chance for occurrence of side effects.  The stimulants, caffeine specifically, in Instant Knockout could become overstimulating, particularly to those who may be sensitive to caffeine.

  • Rapid heartbeats
  • Jitters
  • Anxiety
  • Irritable
  • Headache
  • insomnia
  • Aggressive
  • Difficulty focusing

You won’t want to take this in conjunction with any other supplement that has caffeine in it.  You also won’t want to indulge in caffeinated products while taking the product.

Glucomannan is a thickening agent and it is necessary to drink loads of water with this particular ingredient so that there is no likelihood for it to expand and cause any kind of choking issue or bloating within the stomach. This dose is pretty low, though, so side effects are unlikely.

Overall, as the company claims, these are plant extract ingredients along with vitamins and minerals which are completely natural and should be healthy with no adverse side effects.


Instant Knockout comes in small capsule form (750 mg) taken orally

  • 1 capsule taken 4 x each day along with a glass of water
  • Immediately following waking in the morning prior to breakfast
  • In between your breakfast and lunchtime
  • One hour post lunch
  • One hour prior to dinner

You want to take your last dose at least five hours before going to bed so the caffeine doesn’t keep you awake

The reviews for Instant Knockout were basically split down the middle with the folks who felt that it worked and those that saw no results at all.  Some saw immediate results, but they combined it with exercise and strict diets in conjunction.  They were very happy, definitely would highly recommend it and were going to continue with the use.

There were others who found absolutely no results of any kind and actually some who gained weight while taking the supplement.  A few said that they had also been exercising and eating right with the product, but that it just wasn’t what it claimed to be even after taking it for the recommended 90 days. 

There were many people who took issue with Instant Knockout’s customer service, the money-back guarantee, and refund policies.  All of these folks were very unhappy with each of these things.  They said it is virtually impossible to get your money back once you buy the product and considered the company to be a ‘scam’.

It’s really difficult to know if the ones who had bad results were following the directions as closely as what they should have because the dosage and how you’re to take it are very specific.  It’s also very clear that you are to take this along with an exercise and healthy diet regimen.  That’s not saying that these folks did not do that.  The ones who lost the weight may have done so simply because they followed a very stringent exercise and diet routine.  It’s difficult to know.


Instant Knockout is a very popular supplement with great endorsements and a large following.  Does that mean it works?  The ingredients don’t really stand out as anything extraordinary or unusual from that of any other supplement.  In their combination and at their doses, they’re obviously doing something right. It’s a leading supplement on the market for a reason.
