Energy drinks get talked about in extremes. Either they are the reason you finished the shift, or they are the reason you could not sleep until 3am. The truth is duller and more useful. Caffeine is a tool. It works very well for some situations and does almost nothing for others.
Here is an honest look at when a can of Black actually earns its place, and when you are better off with water and an early night.
What is actually in the can
Black contains 32mg of caffeine per 100ml. That works out at roughly:
- 250ml can: about 80mg of caffeine, the same ballpark as a strong espresso
It also contains taurine, and B vitamins including niacin, pantothenic acid, B6 and B12. The classic version has around 25g of sugar in a 250ml can. The zero sugar version uses sweeteners instead and comes in at around 5 calories per can.
Worth knowing, because the number on the label is the thing that decides whether a can is a sensible pick me up or one too many.
When caffeine genuinely helps
Before training
This is the strongest case. Caffeine is one of the most researched performance aids there is. It reduces how hard effort feels, improves endurance, and helps with focus during a session. European food safety guidance notes that a single dose of up to 200mg does not raise safety concerns for healthy adults, even when taken less than two hours before intense exercise.
Practical version: one can, roughly 30 to 45 minutes before you train. That timing lines up with when caffeine peaks in your system. Drinking it in the car park on the way in means it kicks in around your third exercise, not your first.
If you train in the evening, this is where you need to think. A can at 7pm is still working at midnight.
Long shifts and early starts
Hospitality, healthcare, security, logistics, retail during peak season. Malta runs on shift work, and a lot of it happens when the body would rather be asleep.
Caffeine is genuinely useful here. It improves alertness and reaction time during the parts of a shift where attention starts to slip, typically the middle hours and the final stretch. For anyone driving home after a night shift, that matters beyond just feeling awake.
The trick is one can at the right moment rather than steady sipping all night. Have it before the dip, not after it has already flattened you.
Study sessions and exam season
Caffeine helps with sustained attention and staying awake. It does not make you smarter, and it does not do much for learning material you have not read yet.
Where it works: a long revision session in the afternoon, or a morning exam after a bad night. Where it does not: an all nighter before a paper. Caffeine can keep your eyes open through the night, but sleep is when memory actually consolidates. Trading sleep for study hours usually costs you more than it gains.
When caffeine does not help
When you are actually just tired
Caffeine blocks the signal that tells you that you are tired. It does not replace rest. If you have been running on five hours of sleep for a week, a can will not fix that, and stacking more cans through the day will make sleep worse that night. This is the loop that gives energy drinks a bad name, and it is usually a sleep problem rather than a caffeine problem.
In serious heat
A Maltese July afternoon is not the moment for a stimulant. If you are working outdoors, at the beach or training in the heat, hydration comes first. Water, then caffeine if you still want it. A cold can is not a substitute for fluids on a 35 degree day.
Late in the day
Caffeine hangs around. Roughly half of it is still in your system five to six hours after you drink it, and as little as 100mg in a single dose is enough to make some people take longer to fall asleep and sleep less overall.
If you are in bed by 11, your last can should ideally be early afternoon. If you are a shift worker finishing at 6am, the same logic applies in reverse. Stop caffeine several hours before you plan to sleep, whenever that sleep is happening.
Alongside alcohol
Caffeine masks the feeling of being drunk without making you any less impaired. You feel more alert than you are, which is exactly the wrong combination on a night out.
If you are under 18, pregnant or sensitive to caffeine
Black carries a high caffeine warning on the can and is not recommended for children or for pregnant or breastfeeding women. Guidance for pregnancy is to stay under 200mg of caffeine a day from all sources.
A growing number of European countries now restrict energy drink sales to minors, and for teenagers the recommended intake is calculated by body weight rather than a flat number. Some adults are simply caffeine sensitive too. If one can gives you a racing heart or the jitters, that is useful information, not something to push through.
The simple rules
For healthy adults, the widely used guidance is up to 400mg of caffeine a day from all sources, and up to 200mg in one go. That is roughly five 250ml cans of Black across a day at the outer limit, but remember coffee, tea, cola and chocolate all count toward the same total. Most people who drink coffee in the morning have already used part of their budget before the first can.
Three things worth remembering:
- Time it. Around 30 to 45 minutes before you need it, not during.
- Count everything. Coffee counts. Tea counts. Two cans plus three coffees adds up faster than you think.
- Water alongside, especially in summer.
Used well, caffeine is a genuinely good tool for a hard session, a long shift or a heavy study week. Used to paper over lost sleep, it just moves the problem to tomorrow.
