Youve most likely taken in caffeine almost every day of your adult life if youre anything like the huge bulk of Americans.
The concern is, do you do it due to the fact that you like it, or because you need it?
In a March 2022 study performed by the International Food Information Council (IFIC), respondents over the age of 65 usually stated they drink caffeinated beverages due to the fact that they take pleasure in the taste, while under-45s were most likely to report taking caffeine entirely for its popular benefits as a stimulant. [1] But these benefits belong to a compromise that may not be worth it if you do not actually look after the taste– or possibly even if you do.
Factors to Avoid Caffeine
Although caffeine can certainly lift your energy levels and improve physical and mental efficiency, it can likewise leave you feeling jittery and– as soon as the notorious “caffeine crash” kicks in– seriously tired out.
Insomnia, high blood pressure, heart palpitations, headaches, dizziness, intestinal distress, and anxiety are among caffeines most typical adverse effects, and day-to-day usage also includes the threat of developing a tolerance (so you require more and more to feel the exact same stimulating result) or becoming addicted, which can mean suffering withdrawal symptoms, too.
Some wonderful, natural alternatives to caffeine can be found in todays market that can offer you with a comparable energy and performance increase, but in a much healthier way– so no jitters, no crash, and no getting hooked.
Here are three of the best, with a rundown of the science behind them:
Zynamite
Established by Spanish nutraceutical company Nektium and released commercially in 2018, Zynamite is a patented extract of Mangifera indica (mango tree) leaf that wowed judges at the 2018 NutraIngredients Awards, where it won Ingredient of the Year in the Sports Nutrition classification– with its clinically proven “ability to replace caffeine without any of the typical side-effects.” [2] Unlike other mango leaf extracts, Zynamite is standardized to consist of a minimum of 60% mangiferin, which has the ability to cross the blood-brain barrier and upregulate dopamine in a method similar to caffeine however accomplishes this without obstructing the adenosine receptors [3]– the system accountable for both the advantages and negative effects of caffeine.
Rather, mangiferin hinders the catechol-O-methyltransferase (COMT) enzyme that breaks down dopamine in the prefrontal cortex, [4] thus boosting dopamine levels without triggering the accumulation of adenosine that typically leads to caffeine crash. [5]
A 2020 study led by teacher David Kennedy, director of the Brain, Performance & & Nutrition Center at Northumbria University in the UK, found that a single dosage of Zynamite in healthy adults resulted in substantial improvements across a vast array of brain functions for up to 6 hours– cognitive benefits that the studys authors noted were “broader and longer lasting than those that would be anticipated after caffeine.” [6] 9]
EnXtra
Another acclaimed caffeine alternative is EnXtra, a proprietary extract of Alpinia galanga (galangal– a herb from the ginger family) developed by Mumbai-based ENovate Biolife that took home prizes for Ingredient of the Year in the Sports Nutrition and Cognitive Function categories at the 2019 NutraIngredients Awards and the 2021 NutraIngredients-USA Awards, respectively. [10] EnXtra operates in similar method as caffeine, suppressing adenosine receptors and hindering dopamine reuptake, however with one crucial difference: whereas caffeine is a vasoconstrictor that increases blood pressure and decreases cerebral blood circulation– the main reason for caffeines unpleasant cardiovascular adverse effects, colloquially called jitters– EnXtra has no negative effect on blood circulation or heart rate. [11] Even in the locations where caffeine excels as a stimulant– increasing psychological awareness, focus, attention, and energy– EnXtra surpasses its competitor, with the Alpinia galanga extracts no fewer than 8 recognized dopaminergic bio compounds [ 12] interacting synergistically to provide longer-lasting and superior neurostimulator benefits.
Current studies have discovered that EnXtra consistently improved awareness [13] and focused attention [14] over five hours, whereas caffeine temporarily improved ratings in these locations before causing a crash at around the three-hour mark. Unlike caffeine, which normally displays a “ceiling effect,” whereby a tolerance is rapidly constructed up and the chemical ceases to provide further advantages after even a short period of consistent (i.e. everyday) light-to-moderate usage, EnXtra “showed a constant and acute enhancement in alertness and did not decline throughout the 180 days of use,” according to a long-lasting security and effectiveness study conducted in 2019. [11] The results of the security research study likewise showed that there are no withdrawal signs related to abstinence from EnXtra after an extended duration of twice-daily intake– once again, unlike caffeine.
TeaCrine
Marketed as “a patented compound that delivers energy, mental clearness, and enhanced inspiration and state of mind,” [15] TeaCrine was established by California-based nutraceutical firm Compound Solutions and made its commercial debut in 2015.
TeaCrine is structurally comparable to caffeine, and for that reason acts through the very same dopaminergic and adenosinergic pathways, but has a half-life of around 20 hours– a lot longer than caffeines approximate five-hour half-life [16]– and so stays active within the bloodstream for much longer.
The adenosinergic activity of TeaCrine compared to caffeine is likewise somewhat various; while caffeine blocks adenosine receptors completely– which causes an accumulation of the chemical sleep signals that eventually overwhelm the brain, causing the familiar caffeine crash result– TeaCrine is much less antagonistic, consequently preventing an unexpected crash. [17] An early pilot research study found that TeaCrine dramatically minimized fatigue and anxiety while substantially increasing energy, motivation, concentration, and sex drive, over the course of 6 hours after a single dose, [18] therefore showing that the impacts are much longer-lasting than those of caffeine.
A later safety research study likewise found that TeaCrine has no observable influence on heart rate or blood pressure, might in fact lower cholesterol levels, and– crucially, unlike caffeine– is entirely non-habituating. [19] Final Thoughts
Many individuals enjoy caffeinated beverages, however if youre one of the growing variety of people who just consume them for their health and efficiency benefits, the side results of caffeine probably arent worth it.
Even if you do take pleasure in caffeine drinks like coffee or energy beverages, you might still be keen to discover a less addicting option, one that doesnt put your long-term health at danger.
Thankfully, the caffeine alternative market is blowing up today, and nutraceutical products such as Zynamite, EnXtra, and TeaCrine have real science to support their claims of efficiency.
With these products scientifically shown capability to increase energy and focus– similar to caffeine, and in lots of cases even much better than caffeine– without triggering jitters, crashes, tolerance, or dependency, might the worlds most popular stimulant soon be a distant memory?

— the mechanism accountable for both the benefits and side impacts of caffeine.
EnXtra works in much the exact same method as caffeine, suppressing adenosine receptors and inhibiting dopamine reuptake, but with one crucial distinction: whereas caffeine is a vasoconstrictor that increases blood pressure and minimizes cerebral blood circulation– the main cause of caffeines undesirable cardiovascular side impacts, informally understood as jitters– EnXtra has no adverse result on blood flow or heart rate. Unlike caffeine, which usually shows a “ceiling result,” where a tolerance is rapidly built up and the chemical ceases to offer more benefits after even a brief period of constant (i.e. daily) light-to-moderate usage, EnXtra “showed a acute and constant improvement in alertness and did not decline throughout the 180 days of usage,” according to a long-term security and efficacy study carried out in 2019. The adenosinergic activity of TeaCrine compared to caffeine is likewise a little various; while caffeine obstructs adenosine receptors entirely– which leads to a build-up of the chemical sleep signals that ultimately overwhelm the brain, causing the familiar caffeine crash impact– TeaCrine is much less antagonistic, consequently avoiding an unexpected crash. A later safety study likewise discovered that TeaCrine has no observable impact on heart rate or blood pressure, may in fact reduce cholesterol levels, and– most importantly, unlike caffeine– is completely non-habituating.
