Does theacrine increase heart rate?
Heart Rate and Blood Pressure As can be seen in (Table 3), theacrine at either dosage resulted in a negligible increase in HR in both men and women. For example, the largest increase of approximately 3 bpm was noted for women between pre and 0. Studies indicate that theacrine provides longer-lasting, smoother energy than caffeine. Longer-term studies do not indicate any negative side effects such as jittery feelings or heart-rate increases with theacrine (see Kuhman et al. Taylor et al.Like caffeine, theacrine stimulates the central nervous system at higher doses and decreases central nervous system activity at lower doses. But unlike caffeine, theacrine does not seem to affect blood pressure. Theacrine might also lessen liver damage caused by stress and reduce pain and swelling.In addition to the benefits mentioned in clinical trials, animal model data have indicated that theacrine increases locomotive activity in rodents, without promoting tolerance of the body to supplementation, as occurs with caffeine [4,12]. The literature has also shown the safety of its use in humans [9].Dietary supplement with 5–850 mg theacrine would improve mood, energy and focus, accompanying with reduction of anxiety or fatigue (25). A formula containing theacrine and caffeine with weight ratio 2:1 to 4:1 induced an increase in energy of at least 8%, accompanying with a decrease in fatigue at least 6% (26).
Is theacrine addictive?
A human study of a branded form of theacrine known as TeaCrine® found that supplementing with up to 300 mg daily for more than eight weeks is considered clinically safe and not habit-forming. TeaCrine ®, a patent-pending compound, has energy-boosting effects similar to caffeine, but without the jitters, crash and habituation that often accompany caffeine. It also delivers mental clarity, and improved motivation and mood.These findings support the clinical safety and non-habituating neuro-energetic effects of TeaCrine® supplementation over 8 weeks of daily use (up to 300 mg/day). Moreover, there was no evidence of a tachyphylactic response that is typical of neuroactive agents such as caffeine and other stimulants.TeaCrine provides a lot of benefits to athletes and gym-goers. In addition to increasing one’s energy before a workout, it can also help to improve mental clarity and cognitive abilities.In addition to the dopamine boosting effects, TeaCrine is also thought to inhibit adenosinergic activity. Adenosine plays an imperative role in biochemical processes, that promote fatigue and relaxation. By inhibiting the activity of adenosine receptors, TeaCrine may help delay perceived feelings of fatigue [R].Unlike caffeine, TeaCrine® had no impact on blood pressure, heart rate, irritability or jitters from acute dosing (125mg). This means TeaCrine® is not a stimulant, though it pairs well with stimulants like caffeine. This is important for those who are sensitive to caffeine, but want improved energy without the crash.
Does theacrine affect sleep?
Perceptions of sleep and arousal were largely unaffected by the consumption of theacrine. Participants perceived a significantly longer sleep onset latency when consuming the 400 mg dose of theacrine 12 h prior to bedtime compared to the placebo, despite no significant effect when assessed objectively. Tranquil energy – Unlike caffeine, which can give you a temporary energy boost and then leaves you crashing, theacrine may provide smoother, sustained energy. The effects can last as long as 8 hours, as opposed to the 4 hours of energy that coffee offers.These effects can include increased breathing and heart rate, and increased mental alertness and physical energy. Depending on the individual, these effects can last up to 12 hours. Some of the signs and symptoms of having too much caffeine include: a rise in body temperature.Structurally, caffeine (and the other methylxanthines) resembles the purines. The mean half-life of caffeine in plasma of healthy individuals is about 5 hours.Studies indicate that theacrine provides longer-lasting, smoother energy than caffeine. Longer-term studies do not indicate any negative side effects such as jittery feelings or heart-rate increases with theacrine (see Kuhman et al. Taylor et al.
Is theacrine stronger than caffeine?
Both caffeine and Theacrine can fuel your day but they do so differently. Caffeine delivers fast energy with potential side effects, while Theacrine offers a cleaner, longer-lasting boost with fewer jitters. Depending on your needs, one might suit you better—or you might benefit from using both accordingly. Like caffeine, theacrine stimulates the central nervous system at higher doses and decreases central nervous system activity at lower doses. But unlike caffeine, theacrine does not seem to affect blood pressure. Theacrine might also lessen liver damage caused by stress and reduce pain and swelling.The dopamine difference for theacrine was illustrated by a human study of 200mg theacrine that increased feelings of energy, motivation to train, willingness to exercise, and concentration vs. Ziegenfuss 2017). No changes in heart rate or blood pressure were noted – something very unlike caffeine.
