Your hands are humming. Your heart is going faster than the task in front of you. You've had two coffees before 10am and now you're too switched on to think straight. You want to feel clear and steady again, and you want your next morning to start better than this one. You cannot flush caffeine out on demand, but you can ride out an episode with water, food, a walk and slow breathing while your body metabolises it, and prevent the next one by keeping your morning dose measured and spaced.
The reason this works is unglamorous. Your body metabolises the caffeine on its own and your nervous system settles. Hydration eases some symptoms like shaky hands or nausea. Light exercise, like a walk, helps your body handle the jittery feeling from the extra adrenaline. Prevention is the better half of the equation, because jitters happen when you take in more caffeine than your body needs or wants. If it destabilises your nervous system, that is not energy. That is stress.
Key takeaways
- Jitters are the shaky, restless feeling after coffee. Symptoms include shaky hands, a racing heart, dizziness, nausea and shortness of breath. They show up when your caffeine intake outruns what your body wants.
- Nothing removes caffeine on demand. Your body metabolises it and your nervous system calms down. Water, food, light movement and slower breathing make the wait bearable.
- Caffeine blocks adenosine, the chemical that normally helps you feel sleepy. It revs up your central nervous system. Past a point, that stimulation turns unpleasant.
- A grande-size coffee drink carries over 300 mg of caffeine, three times a regular cup. Hoola's serve is a published 100 mg, roughly equivalent to one standard cup of brewed coffee.
- Timing beats coffee stacked on coffee. Take Hoola in the morning or early afternoon, and keep it away from bedtime. There is no half serve, no double serve and no weekly total. One 10 g scoop a day.
What are caffeine jitters, and how do you know that's what you're feeling?
Caffeine jitters are the shaky, restless feeling you get after drinking coffee. You know it's caffeine and not a bad mood because of the physical signature: shaky hands, a racing heart, dizziness, nausea and shortness of breath.
They are unpleasant reactions to too much caffeine, including restlessness, anxiety, a rapid heartbeat and trouble sleeping. Drink a large amount quickly and the restlessness can look like slight shaking of the hands or a subtle tremor.
The line is simple. Jitters happen when you consume more caffeine than your body needs or wants. Caffeine does good work, and for some people it also arrives with this downside. It is that anxious, shaky state after too many cups, where concentrating gets harder and you end up frazzled rather than focused.
That last part is the giveaway. Real focus feels quiet. Jitters feel loud. If you are alert but cannot hold a thought for a full minute, you have overshot the dose (and no, nothing cancels your 11am meeting).
How do you calm caffeine jitters down fast right now?
Fastest route: drink water, eat something, walk for ten minutes and slow your breathing while your body does the actual work. Your body metabolises the caffeine on its own and your nervous system calms down. Everything below makes the wait shorter in feel, not in chemistry.
Water first. Caffeine is a diuretic, so it causes you to lose more fluids through urination. Drinking water counters that dehydrating effect and keeps you properly hydrated. It also dilutes the concentration of caffeine in your bloodstream, which reduces its stimulant effect on your nervous system. Hydration eases symptoms like shaky hands or nausea.
Then food. Eating with coffee slows caffeine absorption and smooths out its effects. Then move. Light exercise, like taking a walk, helps your body manage the jittery feeling caused by the extra adrenaline.
Then breathe. Long exhale, longer than the inhale, for a couple of minutes. That is your nervous system exhaling with you.
Hoola exists for people with busy schedules and high ambition, and the point of the formula is to help you feel bright, steady in mind, clear in thought and energised in action. Sitting at your desk vibrating is the opposite of that.
Why does caffeine make you feel wired and shaky in the first place?
Because caffeine removes your brake and presses your accelerator at the same time. Think of adenosine as your body's tiredness meter. Caffeine blocks it, the chemical that normally helps you feel sleepy. Adenosine builds up in your brain through the day and makes you feel tired, and caffeine prevents that from happening. It works primarily by blocking adenosine receptors in the brain.
The accelerator half is the nervous system. Caffeine is a powerful stimulant that mainly affects the central nervous system. It is a central nervous system stimulant, full stop. The biology is simple: caffeine stimulates the nervous system and lifts alertness. Jitters happen because that stimulant revs up your central nervous system.
There is a second layer. Caffeine increases the release of neurotransmitters like dopamine and norepinephrine, which makes you feel more alert and awake. By increasing neuron firing and that neurotransmitter release, caffeine can improve mood and concentration. Useful. Up to a point. As you take in more and more, excessive stimulation of the CNS produces the unpleasant jittery effects.
Your point sits somewhere different from everyone else's. How strongly you react depends on dose, timing, body size, genetics and whether you take caffeine on an empty stomach. Your genetics, age, weight, tolerance and liver all shape how quickly you process it.
We do not chase intensity. We support regulated energy, clear thinking and capability that lasts. Not pushing harder, just operating brighter.
Why does a measured 100 mg feel different from a big coffee?
Because you know the number, and it is a modest one. Hoola contains 100 mg of caffeine per serve, roughly equivalent to one standard cup of brewed coffee. It is included at a measured dose so it can do its job for alertness and focus without dominating the rest of the formula.
Coffee gives you no such certainty. Caffeine in beverages varies enormously depending on the strength of the drink and how much you consume. Standardising the measurement is tough, because it depends on bean origin, flavour, roast and grind, plus water temperature and brewing time. A typical cup of brewed coffee runs from 65 to 120 milligrams, while a shot of espresso ranges from 40 to 75 milligrams. One cup means 8 ounces, about an average mug. A grande-size coffee drink carries over 300 mg, three times a regular size cup.
| Caffeine | How certain is the number? | |
|---|---|---|
| Standard cup of brewed coffee | 65 to 120 mg | Varies with bean, roast, grind, water temperature and brewing time |
| Shot of espresso | 40 to 75 mg | Varies with the strength of the drink and how much you consume |
| Grande-size coffee drink | Over 300 mg | Three times a regular size cup |
| Hoola, one 10 g scoop | 100 mg | Published per gram and per serve on the ARTG |
Caffeine is a powerful stimulant that can lift alertness, concentration, endurance and overall mind-body performance. We keep it modest and let the rest of the formula carry the day. enXtra works alongside caffeine to support a smoother, more sustained sense of focus, so the dose can stay modest. In Hoola, caffeine supports mental alertness, reaction time and focus, supports natural energy levels and helps temporarily relieve fatigue.
People no longer want energy that spikes, focus that jitters or calm that sedates. They want brightness: energy that feels clean, clarity that feels steady, calm that feels capable. A gentle lift, not the shakes.
What exactly is in Hoola, and where can you check the caffeine number yourself?
You can check it yourself on the public ARTG register. Hoola is a Listed Medicine on the Australian Register of Therapeutic Goods, AUST L 508472, with an ARTG start date of 8 August 2025 and sponsor Hoola Australia Pty Ltd. The certificate lists all 27 active ingredients with exact quantities per gram. Caffeine is 10 mg/g, which is 100 mg in the 10 g serve.
We are transparent about what is inside. Every ingredient is delivered at a clinically efficacious dose, and every quantity is published. No proprietary blends. Every per-serve figure is the per-gram figure times ten, and both are published.

How do you set up a morning that doesn't leave you jittery?
Give yourself one known dose, early, with water and food, instead of coffee stacked on coffee. Dehydration is another reason jitters show up, so the water is doing real work.
The ritual is one scoop. Mix one 10 g scoop into 300-400 ml of cold water each morning. There is no half serve, no double serve and no weekly total. Hoola is one 10 g scoop a day. Take it in the morning or early afternoon, and avoid it close to bedtime because of the caffeine.
Then leave it alone. The value shows up with repetition, not with a bigger dose. Most of our customers feel the biggest benefits with consistency, and adaptogens may take 4-6 weeks for their full benefits. The 150 g pouch is two weeks. Start there and see how you feel.
Hoola sits at the intersection of calm and capability. One scoop, steady energy, all day, with no second coffee at 2pm to paper over the first one. More from us at the Hoola blog.
Frequently asked questions
How long do caffeine jitters usually last?
Until your body has metabolised the caffeine, which varies from person to person. Your body metabolises it on its own and your nervous system calms down. How strongly and how long you react depends on dose, timing, body size, genetics and whether you took it on an empty stomach. Your genetics, age, weight, tolerance and liver all play a role in how quickly you process caffeine. Two people, same coffee, very different afternoons.
What is the fastest way to take the edge off caffeine jitters?
Drink water, eat something, then walk. Hydration eases symptoms like shaky hands or nausea. Drinking water counters caffeine's dehydrating effect and keeps you properly hydrated. Eating with coffee slows caffeine absorption and smooths out its effects. Light exercise, like taking a walk, helps your body manage the jittery feeling caused by the extra adrenaline. Do all three and the next twenty minutes get a lot more liveable.
What are the symptoms of caffeine jitters?
Caffeine jitters are unpleasant reactions to too much caffeine, including restlessness, anxiety, a rapid heartbeat and trouble sleeping. The physical symptoms include shaky hands, a racing heart, dizziness, nausea and shortness of breath. Take in a large amount quickly and you can get a jittery restlessness that resembles slight shaking of the hands or a subtle tremor.
Why do caffeine jitters feel so much like anxiety?
Because your body runs the same stress program. A sudden intake of caffeine can raise your stress hormones and put your body into fight or flight mode. Too much coffee can leave you anxious and restless. When the stimulation gets too strong, you feel it as jitters. Your body cannot tell the difference between a hard deadline and a triple shot. Stress hits too quickly either way.
Are caffeine jitters a normal reaction?
Yes. Jitters happen when you consume more caffeine than your body needs or wants. For some people, caffeine arrives with that downside. It leads to jitters or shakiness especially in people who drink large amounts or who are particularly sensitive to it.
Why do you get jitters after only one cup of coffee?
Because one cup is not a fixed amount, and you are not a fixed variable. A typical cup of brewed coffee has caffeine levels from 65 to 120 milligrams, while a shot of espresso ranges from 30 to 50 milligrams. Standardising it is tough, because it depends on bean origin, flavour, roast and grind, plus water temperature and brewing time. Then there is you. As you get older, your body's ability to metabolise caffeine may slow down, making you more susceptible to the jittery effects. People with faster metabolisms process caffeine more quickly, which can also mean the stimulant effects hit harder and faster.
What helps dizziness after drinking coffee?
Water and food, and give it time. When you become over-caffeinated, one potential symptom is lightheadedness. A sudden influx of caffeine can go straight to your head and make you feel dizzy. Too much coffee can leave you jittery, anxious or dizzy, signs your body has had excess caffeine. Caffeine is also a diuretic, so it causes you to lose more fluids through urination, which is why hydrating helps.
Does eating something help with caffeine jitters?
Yes. Eating with coffee slows caffeine absorption and smooths out its effects. Slower absorption means a gentler curve instead of a spike, and less of that hollow, shaky feeling that comes from caffeine on an empty stomach.
Can you prevent caffeine jitters instead of treating them?
Prevent them. Know your number and keep it steady. Caffeine in beverages varies enormously depending on the strength of the drink and how much you consume, which makes coffee a moving target. Hoola's caffeine is included at a measured dose so it can do its job for alertness and focus without dominating the rest of the formula, at 100 mg per serve, roughly equivalent to one standard cup of brewed coffee. Drink water alongside it, since water dilutes the concentration of caffeine in your bloodstream and reduces its stimulant effect on your nervous system.
What can you drink instead of a second coffee?
One 10 g scoop of Hoola mixed into 300-400 ml of cold water, taken in the morning. There is no half serve, no double serve and no weekly total. One scoop a day, so the 2pm decision stops being a decision.
How much coffee counts as too much?
It depends on the cup, and the cup keeps changing size. One cup is 8 ounces, about an average mug of coffee. A grande-size coffee drink has over 300 mg of caffeine, three times as much as a regular size cup. Order the large and you have had three coffees, whatever the count in your head says.
Do supplements help with caffeine jitters?
The useful ones let you keep the caffeine dose low. In Hoola, enXtra works alongside caffeine to support a smoother, more sustained sense of focus, so the dose can stay modest. Cordyceps is the energised performance counterpart: where caffeine offers a short, sharp lift, Cordyceps is included for sustained, lower-key energy support throughout the day. Ashwagandha carries the calm clarity side, helping support the body's natural stress response. Energy that lifts but never shakes.
