How Does Smart Caffeine Work?
Smart Caffeine increases people’s focus and enhances alertness because of its two main ingredients. These ingredients are caffeine and L-theanine. While caffeine gives you the energy you need to pursue mental activities, L-theanine smooths out any side effects that are produced by the caffeine. Therefore, you can stay focused and alert without feeling jittery or experiencing a crash.
The ingredient listing in Smart Caffeine is pretty basic. It contains 100 milligrams of natural caffeine (from coffee beans) and 200 milligrams of L-theanine. The capsule is made up of cellulose, vegetable stearate, and silica.
Caffeine is a substance that can be found in over 60 plants in nature. Besides being extracted from coffee beans, caffeine is also found in tea leaves, kola nuts (used to flavor colas), and cacao pods (which are used to make chocolate).
Most people receive caffeine in their drinks. While the amounts can differ, an eight-ounce cup of coffee normally has about 95 to 200 milligrams of caffeine. Compare that with the same sized cup of tea, which contains about 14 to 60 milligrams. A can of cola in a 12-ounce size contains about 35 to 45 milligrams of caffeine, while an energy drink many contain from 70 to 100 milligrams of the stimulant. Typically, it is safe for most people to consume as much as 400 milligrams of caffeine daily.
Caffeine is considered a stimulant of the central nervous system (CNS), as it makes a person feel instantly awake and enhances his or her level of energy. The substance is also considered a diuretic. Therefore, its consumption permits you to get rid of additional water and salt. The intake of too much caffeine may interfere with calcium absorption. The product is known to increase the blood pressure as well.
While most people are familiar with caffeine, L-theanine is not an ingredient that is so familiar – unless, of course you have acquainted yourself with nootropic ingredients or supplements. L-theanine is an amino acid, or a building block for protein. It naturally occurs in the leaves of green tea. While it promotes relaxation, it does not have a sedative effect.
L-theanine is similar in its chemical structure to another amino acid – glutamate. Glutamate assists in the transmission of cerebral nerve impulses. This ingredient and supplement is often suggested for people who suffer from memory conditions such as dementia and Alzheimer’s disease.
However, it has also been shown that a person with a healthy brain can benefit substantially from L-theanine effects. The substance is unique, as it can easily cross over the blood-brain barrier. This means the ingredient takes a direct path to the brain.
Because of its calming effect, L-theanine lessens stress, as it increases the levels of serotonin and dopamine in the brain. These two chemicals give people a sense of euphoria. Therefore, they are often labeled as feel-good substances. As a result, teas, such as green tea or oolong tea, are known for their relaxing effects.
When L-theanine is combined with caffeine, you receive the best of both ingredients. L-theanine is highly recommended for stacking with caffeine because both ingredients, when working together, notably enhance cognitive performance. This synergistic effect supports an increased attention span and better focus.
Stacking caffeine with L-theanine is a popular brain-boosting choice, as it benefits anyone seeking mental benefits that are both affordable and easy to obtain.
Because Smart Caffeine is a highly efficient blend of caffeine and L-theanine, it provides lasting energy throughout the day without the jitters associated with caffeine. Users of Smart Caffeine comment that they enjoy the following advantages:
- Easier concentration or the ability to more easily ignore distractions
- Enhanced alertness and focus
- Improved cognitive functioning
- Better short-term memory retention
- No effects from over-stimulation
The “smart” combination of caffeine and L-theanine makes Smart Caffeine the ideal product to take for anyone who wants to perform at his or her level best, whether on the job or working around the house.
The supplement makes it possible for you to enjoy all the benefits of a cup of coffee without some of the unsettling side effects. In addition, the open source labeling on the product ensures that you will receive exactly what the label states.
If you took caffeine alone, you may be subject to the following side effects, provided you consumed too much:
- Shakiness or restlessness
- Abnormal or rapid heart beat
Some people develop a dependency on caffeine if they consume too much. However, caffeine is combined with L-theanine in Smart Caffeine to protect the user from feeling jittery or out of sorts. Nevertheless, if you are especially sensitive to caffeine, you may need to cut down on the dose you take.
The manufacturer of Smart Caffeine suggests users take one to two capsules whenever they require more focus and energy. The company also recommends that the user avoid taking the product in the evening. Doing so can lead to sleep problems. Users of the product should not take any more than six capsules per day.
While the company says the product can be taken on a daily basis, it suggests refraining from taking the supplement one or two days per week, such as over the weekend.
If customers have complained about any problems with Smart Caffeine, it has to do with some of the side effects experienced when a person over-consumes caffeine.
These side effects include:
- problems with sleeping
- abnormal heart beat
- problems with sleeping
However, the website of the manufacturer does provide tips on its blog and in its newsletter to prevent these issues from occurring.
If you are highly sensitive to caffeine, you may need to adjust your dosage if you feel dizzy or anxious. Otherwise, it may be better to seek a non-caffeine product if you are having any problems with the caffeine.
If you find this to be the case, you may want to consider Ciltep, which is another brain booster offered by Natural Stacks. Natural Stacks also features two other products that do not contain caffeine – Acetylcholine Brain Food and Dopamine Brain Food.
Most customers report that they love taking Smart Caffeine to sharpen their focus and to get things done. For example, verified buyers have provided the following testimonials.
One customer who was over 55 years old, said that he loved Smart Caffeine. The former coffee drinker elaborated on the point further. He said, “With Smart Caffeine I maintain focus and mental energy with no jitters or crash.” He said he only took one capsule per day.
Another customer, aged 25 to 34 years old, said that Smart Caffeine was an exceptional product. He commented as follows, “These guys are the tried and true kings of the supplement industry. Never been disappointed. . . .”

Yet another customer commented that Smart Caffeine was his new morning coffee. He said, “[Smart Caffeine] helps me get up in the morning and stay focused throughout the day.”
