Smart Caffeine Review

Smart Caffeine is a fairly simple but effective supplement that consists of only two ingredients – natural caffeine and l-theanine.

Smart caffeine review

Its formula is pretty much the same as of other similar products with one important difference – the company which developed the product (Natural Stacks) is using only the purest ingredients possible, and it is known for its high-quality products.

I’ve been taking similar kind of products before and most of the time I was satisfied with the effects.

And the same is true for Smart Caffeine.

I’ll be totally honest with you – I love drinking coffee. I love the smell of it, I love the taste, I love the whole procedure of making it.

Even though coffee gives me tons of energy (especially the Bulletproof Coffee), I personally hate the crash that follows after drinking it.

Whenever I have a chance, I try to drink coffee in the morning, and then combine it with green tea a couple of hours later.

But if you don’t like this combo, or if your search for a simpler solution that brings similar effects, Smart Caffeine is a product to check.

Since it contains caffeine + L-theanine, I experienced no crash or jitters after taking it. This supplement will give you a lot of energy and focus without feeling the adverse side effects of drinking coffee.

During my test period, I experienced no issues whatsoever and I simply love it.

Smart Caffeine supplement is not much different from other similar products, but since I know the company behind it, I’ll stick with it.

Smart Caffeine Ingredients

Here is the list of both ingredients in Smart Caffeine:

  • 100 mg Natural Caffeine
  • 200 mg L-Theanine from green tea

The formula of Smart Caffeine is pretty simple and straightforward.

Smart Caffeine Ingredients


L-Theanine is a naturally occurring amino acid with benefits that include mental relaxation, reduced stress, improved working memory, enhanced learning, and increased alpha brain wave activity.

It is one of my favorite nootropics that has the role of a relaxing agent without sedation. The relaxing and attention promoting properties of L-Theanine have its most significant supplemental role in attenuating the edge of many stimulants.

A combination of L-Theanine with caffeine is noted to promote cognition and attention. [1]

Natural Caffeine

Caffeine is the world’s most popular natural cognitive enhancer.

It is a powerful stimulant which is used to improve physical strength and endurance. Why is it classified as a nootropic?,

Mainly because it sensitizes neurons, and also because it provides mental stimulation. Caffeine’s main mechanism concerns antagonizing adenosine receptors.

It causes alertness and wakefulness. The inhibition of adenosine can influence the dopamine, serotonin, acetylcholine and also adrenaline systems. [2]

Smart Caffeine Dosage

The suggested dosage of Smart Caffeine is 1-2 capsules whenever focus and attention are desirable.

According to Natural Stacks, it is not recommended to take it in the evening or before sleep.

Also, it is not recommended to take more than 6 capsules per day.

Whenever I need an extra push, I take 2 capsules of Smart Caffeine, but I avoid taking it daily.

I prefer to take it in the morning after breakfast.

I’d definitely advise you to NOT take the supplement after 2 PM just to avoid any sleep-related issues.

For the ultimate performance, I’d recommend you combining Smart Caffeine with my favorite nootropic stacks.

Smart Caffeine Reviews

Alongside all other products of Natural Stacks, Smart Caffeine has also a great reputation! Natural Stacks’ reputation is definitely not in vain.

There are many feedbacks and reviews of this product and here I listed few of them:

“Smart Caffeine provides a boost in mental alertness and focus without any of the jitteriness that comes with other caffeine products. It’s a great product and I highly recommend it!”

“Love this product. I’m usually a 2 – 3 cup of coffee a day. With Smart Caffeine I maintain focus and mental energy with no jitters or crash.”

“Simple yet effective product for a great price. I’m not a big coffee drinker so I thought it still might give me the jitters (even with the l-theanine), but it hasn’t at all. I feel a nice sustained energy from it without the anxious and jitters feeling you can get from drinking coffee or anything with a lot of caffeine. Will buy again.”

“I can unequivocally recommend this product. I have been experimenting with Nootropics for about 2 years with varying results. Personally, I find it hard to quantify how effective some of them are. Sometimes the effects are obvious, other times not so much but when you look back on the time you were taking them and what you got done the advantages becomes a lot clearer. This is one of those rare nootropics products which it’s clear to see the effects immediately. Essentially it does what it says on the tin, energy and focus without the shakes.”

Where To Buy Smart Caffeine?

I’d recommend Smart Caffeine to everyone who is searching for:

  • Increased focus and alertness
  • Improved cognitive function
  • Enhanced short-term memory retention
  • More ability to ignore distractions
  • No overstimulation

You can buy Smart Caffeine here. 

At the price of 19,95 USD, it’s very affordable. 

I’m sure you will love it.
