We take a close look at TigerEYE Smart Energy, to see if it could really give consumers these benefits and to see if it is safe to take.
TigerEYE Smart Energy is an energy supplement with just two ingredients, caffeine anhydrous, and L-Theanine. It is suggested that using these two ingredients together gives you the benefits of both of them, without the usual unwanted side effects, such as jitters or crash.
Smart Energy offers a combination of caffeine and L-Theanine, which supposedly improves your focus and increases energy levels as well. Its regular use provides improved focus with no crash or jitters. Studies have found that caffeine is a stimulant – it stimulates your central nervous system and makes you feel more alert and attentive. L-Theanine is supposed to promote relaxation without drowsiness. The issue is that how caffeine affects your central nervous system varies greatly from one person to another. Similarly, there is insufficient scientific evidence suggesting that an increased intake of caffeine will lead to a substantial increase in energy.
It is manufactured by TigerEYE Nutraceuticals, a US company based in Michigan. However, we have been unable to find out much more about this company which is very concerning.
People are likely to react differently to Smart Energy, due to the differences in the way people metabolize caffeine and the dosage taken. Side effects may include headache, insomnia, irritability, diarrhoea, nausea, increased heart rate and breathing, and high blood pressure.
TigerEYE Smart Energy costs $29.99 for 60 capsules from the official website, $19.98 from Amazon US, or £24.98 from Amazon UK. It is a relatively expensive product if the maximum dose of 4 capsules is taken every day, meaning one bottle would last only 15 days!
TigerEYE Smart Energy provides a combination of L-Theanine and caffeine to help you feel alert but relaxed. It claims to provide you with a cleaner form of energy, but experts believe that caffeine only masks the feeling of tiredness and does nothing to actually increase energy production. Once the effects wear off, you experience an energy crash that makes you feel worse. There are many other side effects associated with caffeine intake, and that is why L-Theanine has been included in the blend, which is supposed to counteract those negative effects. Unfortunately, studies do not support the use of L-Theanine to calm your nerves and reduce the side effects of caffeine.
The price of Smart Energy is a concern, especially if higher doses are taken regularly, particularly for a product containing only two ingredients, one of which is caffeine which is easily (and cheaply) available.
Overall, we do not recommend TigerEYE Smart Energy to our readers.

TigerEYE Smart Energy contains just two ingredients; caffeine and L-Theanine. It is an energy supplement that aims to give premium long-lasting energy and focus for 4-6 hours, ideal for productive activities that call for extended periods of focus and attention. It claims to do this without the usual symptoms of jitters and crash.
This combination of ingredients has been described as the number 1 cognitive performance stack and appears in a lot of other products also available on the market.
Caffeine is an incredibly popular stimulant. It is safe and well tolerated by most people, and ideal for providing a quick energy boost. The downside is that this energy boost is not effective as a cognitive enhancer and as we all know, drinking coffee can leave you feeling strung out, wired, and jittery.
This is where L-Theanine comes in. L-Theanine is an amino acid found naturally in the tea plant and nothing else, so it is not generally taken in dieting, unless you drink tea in high quantities. It is L-Theanine that causes the relaxing but non-sedative effect of tea.
Take 1-2 capsules whenever enhanced focus and energy is desired. Do not take more than 4 capsules per day.
The product description suggests that L-Theanine and Caffeine work well together because the L-Theanine helps to smooth the effects of the caffeine without losing that energy and motivation that caffeine can cause. It is important to remember that all tea does contain caffeine and L-Theanine so regular tea drinkers may already experience this energising yet relaxing effect (and at a more cheaper price!).
However, the effects will only be temporary and will not have a long lasting effect. It is probably best to be used occasionally as an energy and focus booster, rather than as an everyday supplement, especially as you are likely to build up a tolerance to it over time.
TigerEYE Smart Energy claims that it gives a smooth and long-lasting energy and focus, without the harsh unwanted side effects most energy supplements have, in a much cheaper alternative.
It is suggested that the user will feel a mind-energizing, fat burning, and enhanced focus with a sense of calm. It should also improve mood and memory, and help to reduce stress.
We think that is likely that a consumer may experience a slight boost in energy levels and focus for a short time after taking a capsule. However, the effects will be temporary, and if you are already a regular coffee drinker then you may not notice much of an effect. Plus, taking this supplement will require you to avoid caffeine from other sources so you won’t get to enjoy your cup of coffee.
In addition, although caffeine is well known as a stimulant, it is equally well known that as you become accustomed to it, you do build up a tolerance to the effects.
It contains L-Theanine that is supposed to reduce stress and relax your mind, but combining it with caffeine does not make much sense because you may be taking caffeine to stay alert. L-Theanine may help minimize the negative effects of caffeine, but you should not expect any significant improvement in alertness or concentration.
Smart Energy is also very unlikely to improve mood and memory with just these two ingredients.
There could be some side effects from the caffeine in those sensitive to it.
These include:
Caution:
Do not use if you are pregnant, nursing or under the age of 18. Consult with a healthcare practitioner before use.
There are lots of reviews on Amazon UK, the vast majority of which are very positive. However, we analysed the reviews using the FakeSpot website, which suggests a lot of them may be fake.
An example includes:
Just the second day of using this product and it’s fantastic. I normally don’t take any caffeine. Hate coffee and that product is giving me so much energy. Sufferer of MS and this is tackling my fatigue just 2 days.
There are also a few negative reviews which suggest the product gives side effects or doesn’t work at all.
This product works fine and with no jitters as it says. But it DOES give a big come down low (which feels like depression) that lasts for hours on just 1 tablet – let alone the 4 they recommend as the daily limit. In addition, if you are trying to lose weight, DO NOT use caffeine to do it as it makes you ravenous ALL DAY. That’s a lot of side effects for £24 odd. I’m moving over to Yerba Mate tea which has 85 grams of caffeine in 1 tablespoon of loose tea.
It is hard to know whether TigerEYE truly offers a money-back guarantee. There is no mention of it on their official website, however on Amazon they say:

Simply contact Tigereye Nutraceuticals for a full refund. What do you have to lose? Nothing! Unleash the Tiger inside of you today!
So it is hard to know whether they will fulfill these promises or not.
You can buy it from the official website for $29.99 with free shipping. It is also available on Amazon UK for £24.98 and Amazon US for $19.99.
