Theacrine Review 2018 – Benefits & Side Effects (Updated July 2019)

What is Theacrine?

We all want to be fit, build up stamina and look good! When we start working out we all have to follow various work-out regimes, diet plans, protein shakes and drink teas and a variety of caffeine drinks which are used prior to the workouts especially coffee. We may be happy about the fact that coffee helps us to keep up our energy levels and boost metabolism but we can just overlook the side effects. Elevated heart rate, elevated blood pressure, shakiness etc are the common side effects of coffee. Imagine after all the health conscious efforts instead of feeling good you have the above symptoms. Not good, right?


To avoid all these hassles and make our fitness or weight loss journey easier there is an amazing product for you in the market! Theacrine is the miracle drink which I’m sure we all would love to try out. Let’s find out more about Theacrine.


How does it work?

Theacrine is primarily found in the leaves of camellia assamica var which is called as Kucha. Theacrine has been a major component in the Chinese tea known as Kucha. Theacrine is a small alkaloid molecule that is basically a structured version of caffeine. The chemical is actually synthesized from caffeine in certain plants as mentioned above known as Kucha. This component now appears in the pre-workout and energy drinks. The product works a lot like caffeine. It helps to boost energy and performance at the same time decreasing fatigue! Theacrine prevents dopamine from being reabsorbed after it is released in the brain. This causes the levels of dopamine to rise. This increase in the dopamine levels helps in improving mood, increase in energy levels and also provides greater mental focus. While the dopamine levels increase the adenosine is blocked. Adenosine is responsible for the feelings of sedation and relaxation. By a decrease in the adenosine and the increasing levels of dopamine, it increases alertness, physical performances, wakefulness, and coordination. Caffeine’s stimulating properties can make it hard to wind down or fall asleep following a late-night workout. As mentioned above Theacrine is gentler, helping your body return to a state of calm after use.

It’s not likely you will have to keep adjusting your Theacrine dosages over the time. In contrast, the longer you take products containing caffeine, the more your body becomes habituated to it. You must take more and more to produce the same level of stimulation or to get the same effects. But the good news is that it does not appear to work in the same way. A study was taken in 2016 in which 60 participants took 300mg of the product for 60 consecutive days. The participants showed no signs of getting used to the product. This pretty much proves the point that it is a lot safer than caffeine.

In the market, there are various types of Theacrine products available such as:

  • powder
  • capsules
  • tea

Studies related to Theacrine:

A study was conducted by the department of exercise and sports science, human performance lab and exercise biochemistry lab, University of Mary Hardin-Baylor, Belton, TX, USA, wherein a placebo-controlled study  Theacrine demonstrated non-habituating effects in 60 healthy humans over 8 weeks of daily use at up to 300mg/day. In this study, it was demonstrated that Theacrine does not result in a fatigued crash or lead to tolerance build up over time. Also unlike caffeine, Theacrine does not seem to affect blood pressure, cause anxiety or lead to insomnia. In addition to this, it may have benefits that caffeine does not have such as decreasing inflammation and relieving pain. However, it was also demonstrated that if these two compounds i.e. Theacrine and caffeine when taken together; caffeine increases the bioavailability and the positive effects of the substance.

Data published at the 2017 International Society of sports nutrition conference demonstrated a large improvement in reaction time among soccer players after they took a combination of “Teacrine”, a pure form of Theacrine, and caffeine. Researchers suggested that the athletes were able to sustain greater focus under fatigue for a longer period when combining the two ingredients. In addition to fuelling physical exertion, it also delivers a smooth increase in energy that can help boost brain power. When combined with caffeine, it can make it easier to concentrate on the task at hand and help reduce mental fatigue. Data published in the journal of nutrients demonstrated improvements in feelings of attentiveness, alertness, etc.

Another study was done in 2017 study showed that a single 200mg dose of Teacrine significantly improved energy and reduced fatigue. When taken consecutively for seven days the participants noticed improvements in their energy, fatigue, concentration, anxiety, and motivation to exercise.

According to a study done in 2015, after seven days of Theacrine supplementation, subjects showed no signs of desensitization. This means that your first dose is as strong as the 200th dose!


Theacrine dosages, Benefits, and side-effects of Theacrine:

Theacrine appears to have a biphasic dose response. Biphasic does mean that it acts as a sedative at lower doses and ha stimulatory properties at higher doses. It is recommended 50 to 300mg/day. If the Theacrine dose is less than 50 mg/ day the effect is more relaxation inducing whereas the does close to 300mg are stimulatory.

We recommend you to take a qualified physician’s advice as the dosages might differ according to the need of the subject.

The product has a lot of benefits which are better than the caffeine. Below are the health benefits of Theacrine:

  1. Theacrine increases energy, focus and motivation: it is a brain or nervous system stimulant that became popular in sports nutrition as a pre-workout and a fat burner supplement. Theacrine enhances physical activity; this effect is mediated by the adenosine and dopamine systems.
  2. Theacrine improves mood and may help with depression: Theacrine consumed at high doses activates the dopamine receptors. High dopamine levels result in perceived feelings of energy, improved mood, and sensations of pleasure. It also increases the activity in the brain which is associated with pleasure and reward.
  3. Theacrine improves sleep: A low dosage of the substance shortened wake time and increased the sleep time it also reduced caffeine-induced insomnia.
  4. Theacrine reduces inflammation and pain: Theacrine reduces the inflammation and has pain relieving properties.
  5. Theacrine decreases cholesterol: Polyphenols in Theacrine can inhibit the absorption of dietary cholesterol and decrease blood cholesterol levels.
  6. Theacrine combats stress: Theacrine has protective effects on the liver damage which is induced by stress in the body.

As we say a coin has two sides and so does a product. There are a lot of benefits but let’s talk about the side effects as well!

Theacrine has a lot of benefits but as proven it has a very few side effects. In comparison to caffeine, the product has virtually no side effects. One side effect of the substance is the tolerance builds up: over time, your body grows tolerant to caffeine, which means you have to keep taking more and more of it to achieve the same desired effects. Although, this may differ from person to person.

After all the good and the bad effects of Theacrine, it’s always a pleasure to see what the consumers have to say from their personal experiences!

Consumer reviews of Theacrine

“In general, it has essentially all the same effects of caffeine, but slightly weaker stimulation at the same dose and much less noticeable negative side effects like jitters. It also lasts about 6 hours for me as opposed to 3-4 hours of full worth from caffeine”

“As a sleep-deprived college student, 100 mg of this is enough to get me awake enough to get through class and mild compared to caffeine.”

“It works so much better for me than caffeine. It is smoother, longer lasting and the effects are consistent. Sometimes I mix in a bit of caffeine for a little more kick. They work very well together.”

“I took this all on it won as to not confound results from other supplements and saw no noticeable benefits. I took it consistently every day until the bottle was finished. I will not reorder.”

“It is still a very new supplement without a lot of studies. The effects are like milder caffeine. I have noticed an improvement in cognitive abilities and a reduction in fatigue, which seems to last most of the day. Supposed to be no tolerance to it as well. I don’t take it daily, so I can’t speak from experience on that.”

Well, these were the reviews by the very people who used it. I hope that the above information about it might help you make your decision. Also, it is advisable to ask your physician or dietician before consuming any supplements.
