Caffeine can increase alertness and reduce sleepiness. Think of it as support for feeling more awake, not a replacement for rest.

Explore the benefits
Caffeine is a stimulant with well-studied effects. Here’s where the evidence is strongest, with a little context that matters.
Caffeine can increase alertness and reduce sleepiness. Think of it as support for feeling more awake, not a replacement for rest.
The science 1Feeling awake can make a difference when it’s time to engage with your day. Your response depends on sensitivity, sleep and how often you use caffeine.
The context 1, 2Research shows caffeine can improve some exercise outcomes, especially endurance. Study doses vary; these findings don’t establish the effect of a single 50 mg capsule.
The research 3These are findings about caffeine generally, not results from clinical testing of Voltaire. Individual experiences vary.

MEET VOLTAIRE
50 mg of caffeine per capsule, in a format that fits into your day. No brewing. No cup to carry. Just a clearly stated amount of caffeine.
CAFFEINE
PER CAPSULE
A defined amount helps you keep track. It doesn’t guarantee a particular effect or make caffeine right for everyone. Follow the product label.
Be first in lineA café coffee runs five or six dollars. An energy drink is three or four. Do that every weekday and you’re spending well over a thousand dollars a year on caffeine, plus sugar, plus the cup, plus the line. Voltaire delivers a known 50 mg for a fraction of that, with nothing to brew, chill or carry. Keep the coffee you love. Skip the ones you don’t.
Every Voltaire capsule is 50 mg, so you always know how much you’ve had. That makes caffeine easier to plan around. It doesn’t change how it feels or guarantee it won’t touch your sleep. Timing, sensitivity and caffeine from other sources still matter.
The pre-meeting lift. The plans after work. The days that ask a little more of you. Voltaire is our take on everyday caffeine: 50 mg per capsule, in a small, straightforward format.
Knowing the amount helps you track your intake. It does not guarantee how caffeine will feel or that it will leave your sleep unaffected. Timing, sensitivity and caffeine from other sources still matter.
Our caffeine guide and research reading room explain the evidence with its limitations. We distinguish research on caffeine from research on coffee, and neither is presented as clinical testing of Voltaire.
02 , YOUR RITUAL
A good caffeine routine starts with awareness. More isn’t always better.
Coffee, tea, energy drinks and supplements all count. Check labels and include every source when tracking your caffeine.
Caffeine can interfere with sleep, including at relatively small amounts near bedtime. Plan around your sensitivity and your evening.
Jitters, anxiety or a racing heart can be signs of too much caffeine. Reduce your intake and discuss symptoms with a health professional.
03 , GOOD QUESTIONS
The caffeine itself is handled the same way by your body, whether naturally present or added. The format, caffeine amount and other ingredients can differ. A capsule is not inherently safer or more effective than coffee. [2]
No. Sensitivity, regular caffeine use and individual differences affect your response. A stated amount helps you track intake; it cannot predict how you will feel. Follow label directions and account for other caffeine. [2]
No. Feeling more alert is not the same as being well rested. Caffeine can reduce sleepiness, but it can also disrupt sleep. Rest belongs at the center of your routine. [1]
If you’re pregnant, trying to become pregnant or breastfeeding, discuss caffeine with your clinician. Also ask if you take medications, have a medical condition or are sensitive to caffeine. This page is intended for adults. [2]
