Best Fat Burner That Doesn’t Make You Jittery

In a market filled with supplements, it’s hard to determine which products are safe & effective, and which ones will cause side effects.

Well, one of the most common side effects from taking fat burner supplements is that ‘jittery’ feeling. It’s something we all want to avoid, and we’re here to show you exactly how to do this.

In this article, you’ll learn:

  • What are fat burner supplements?
  • Why do they make you jittery?
  • How to avoid jitters
  • Best fat burner that doesn’t cause jittery feelings
  • Conclusion

What are fat burner supplements?

As always, we’re writing this article so those new to supplements can understand everything. If you already know what fat burner’s are, then skip to the next section and stop hating bro.

How they work 

Anyway, these are pretty self explanatory, but fat burner supplements are designed to help you lose body fat at an accelerated rate, by delivering certain benefits.

These include:

  • Raised metabolism
  • Suppressed appetite
  • Elevated energy levels

We believe that the benefits listed above are those that should be offered by all fat burner supplements. However, the problem is that the market is also filled with cheap, ineffective products that don’t work.

Not only that, you’re here because you’ve experienced ‘jitters’ after taking these fat burners before (but we’ll expand on this in the next section).

How to take 

All fat burner supplements offer different daily serving sizes. Some offer 1-2 capsules per day, while others offer 3-4 capsule servings.

Which is the best serving size? Well, studies have proven that consuming 3-4 capsules will keep your body fuelled with the nutrients it needs to boost your metabolism – helping you burn fat faster.

Think about when you were last prescribed antibiotics or medicine; the doctor would have recommended you to take 3-4 pills per day for the same reason. Makes sense, right? Yes, bro.


Why do they make you jittery?

Right, so we’ve come to the conclusion that fat burners can cause that ‘jittery’ feeling. Well, this is because these supplements can contain massive amounts of caffeine.

If you’ve ever consumed too much coffee before, then you’ll know that it’s this same ‘jittery’ sensation, for the same reason.

Ultimately, consuming too much caffeine at once will inevitably cause this side effect.

How much caffeine is ‘too much’?

Caffeine can be very beneficial when consumed in sensible dosages; this stimulant can improve your strength, endurance, focus and energy levels (which are all key benefits that can boost your gym sessions and take the edge off low-calorie diets).

However, when you consume over 100mg per capsule, then caffeine will cause jitters and energy crashes. So it’s important to check the exact dosage of this stimulant on the supplement you’re interested in.

How to avoid jitters

The answer to this question is pretty obvious. But we know that many of you will have been skim-reading this article, so we’ve created a specific subsection for this – we hope that you feel special brah.

So, the best way to avoid that ‘jittery’ feeling is by consuming less than 100mg caffeine per capsule.

However, it’s important to know that caffeine isn’t the only stimulant added to fat burners. In fact, as we mentioned before, caffeine is a key ingredient; this stimulant can help raise your energy levels while you cut carbs and calories from your diet, in order to lose body fat.

For this reason, we’ll list the stimulants that are added to certain fat burners, that you should avoid.

Here’s the stimulants to avoid in fat burners:

  • Synephrine (Citrus Aurantium/Bitter Orange Peel)
  • Yohimbe
  • Ephedrine
  • Raspberry Ketones
  • Guarana Seeds

Ultimately, consuming fat burners that contain high amounts of stimulants (over 100mg per capsule) will cause the ‘jittery’ feeling that you want to avoid.

As a result, by avoiding these supplements and choosing fat burners containing sensible caffeine dosages – you’ll stay safe from unwanted side effects.

However, remember that caffeine isn’t the only stimulant found in fat burners. We’ll also recommend that you avoid any supplements containing more than 1 stimulant too.

Personally, we achieved great results using Instant Knockout CUT, which is why it’s SpotMeBro’s #1 fat burner this year. Most importantly, it didn’t cause any jitters, crashes or any other side effects.
