The best supplements for students are cheap, simple and backed by evidence: caffeine used with care, a multivitamin if your meals are patchy, and creatine if you also train. No supplement replaces sleep, regular meals and water, which do more for focus and energy than anything in a tub. This guide covers what is worth buying in Australia on a student budget, what to skip, and how much caffeine is too much.
Supplements for students at a glance
| Supplement | What it may help with | How strong is the evidence? | Our budget pick | Approx. cost per serve |
|---|---|---|---|---|
| Caffeine | Feeling less tired for a few hours | Good, but it can disrupt sleep | ON Amino Energy (100 mg caffeine per serve), or a coffee or tea | $1.67 |
| Multivitamin | Filling gaps when meals are rushed or limited | Useful for gaps, not needed if you eat well | Condemned Labz Multi | $2.00 |
| Creatine | Training, and possibly memory | Strong for training, small and mixed for memory | Beast Labs Creatine 250 g | $0.40 |
| Magnesium glycinate | Sleep, maybe | Weak, mostly small studies in older adults | Beast Labs Magnesium Bi-Glycinate | $0.50 |
| "Focus" or nootropic blends | Claims vary | Hard to judge, as blends mix many ingredients | Skip on a budget | Not needed |
Cost per serve is worked out from the price and the serve count on each label at the time of writing, so use it as a guide. Everything except the multivitamin costs under $50 a tub, and you can find more good-value options in our under $50 range.
Start with the free stuff: sleep, food and water
Before you spend a dollar, look at the basics. healthdirect recommends 7 to 9 hours of sleep a night for adults, and says teenagers need more than that. A late-night cram followed by a 6 hour sleep will hurt your focus the next day more than any supplement can help it.
- Keep a regular sleep window. Going to bed and getting up at similar times, even on weekends, makes it easier to fall asleep.
- Eat proper meals. Skipping breakfast and living on snacks and energy drinks is the fastest way to an afternoon crash.
- Carry a water bottle. It is free on campus and you will drink more if it is in your bag.
- Keep screens out of bed. healthdirect suggests a wind-down period before sleep without phones or laptops.
Caffeine: how much is safe for students?
Caffeine is the one study aid with good evidence behind it. The AIS rates it as a Group A sports supplement, and it works by reducing the feeling of tiredness. The catch is sleep. healthdirect suggests avoiding tea, coffee and caffeinated soft drinks for at least 3 to 7 hours before bed, so a late coffee during exam week can cost you the sleep you need to remember what you studied.
Food Standards Australia New Zealand (FSANZ) gives these limits from all sources combined:
- Adults: no more than 400 mg of caffeine a day, and no more than 200 mg in a single serving.
- Pregnant or breastfeeding: no more than 200 mg a day.
- Under 18: no more than 3 mg per kilo of body weight in a single serving, which is about 120 mg for a 40 kg teenager.
Count everything: coffee, energy drinks, cola, pre-workout and any caffeine product. FSANZ notes that pure and highly concentrated caffeine powders are banned from retail sale in Australia because of the serious risks. For a full breakdown of how much caffeine is in common drinks, read how much pre-workout caffeine is safe.
If you want a measured dose instead of guessing with energy drinks, Optimum Nutrition Amino Energy has 100 mg of caffeine and 5 g of amino acids in each 9 g serve, with 0 g of sugar (Blue Raspberry). A 30 serve tub is $49.95 at the time of writing. It also contains beta-alanine, which can cause a harmless tingling feeling. Browse more options in our focus and energy range, but check the caffeine per serve on every label.
Do students need a multivitamin?
Not always. healthdirect says most people can get all the vitamins and minerals they need from a healthy, balanced diet. A multivitamin makes more sense if you are living out of home for the first time, eating a lot of instant noodles, or following a restricted diet. It is a safety net, not a replacement for food.
One of our best-selling multis is Condemned Labz Multi. Each 2 tablet serve has 20 µg of vitamin D3, 11 mg of zinc, 400 µg of folate and the B group vitamins, and a bottle holds 30 serves. It is $59.95 at the time of writing, a little over $50 for the bottle. That is about $2.00 a day. The label lists no iron, so it will not cover iron needs. Do not double up with other vitamin products unless your GP suggests it. Compare more options in our best multivitamin guide or the full multivitamin range.
Creatine and magnesium: worth it for students?
Creatine
Creatine is one of the best-studied sports supplements, and the AIS lists creatine in Group A for specific uses in sport. If you go to the gym between classes, it is the most useful thing on this list. The brain link is less clear. A 2023 review of randomised trials found creatine improved memory scores compared with a placebo, but the effect was clearer in older adults than in younger people, and the trials were of moderate quality. Take it for training and see any study benefit as a possible bonus.
Beast Labs Creatine Monohydrate 250 g is single-ingredient micronised creatine, 5 g per serve and 50 serves per tub, for $19.95. That works out at about $0.40 a serve.
Magnesium
Magnesium is popular for sleep, but the evidence is weak. A 2021 review found only 3 small trials with 151 older adults, and rated the evidence as low to very low quality. If you sleep fine, you are unlikely to notice much. If you want to try it, Beast Labs Magnesium Bi-Glycinate gives 150 mg of elemental magnesium per capsule, with 60 capsules for $29.95. Fix caffeine timing and screen time first.
Under 18? Read this first
School students have different needs from uni students. Most teenagers do not need supplements, caffeine limits are lower, and some products are labelled for adults only. If you are under 18, talk to your GP or a sports dietitian before you buy anything, and bring a parent along. The same goes for anyone with a medical condition, anyone taking medication, and anyone who is pregnant. Our guide to supplements for teenagers explains what is and is not appropriate at that age.
Our pick for a student budget
- Spend nothing first: sleep 7 to 9 hours, eat real meals, and keep coffee to the morning and early afternoon.
- If you train: Beast Labs Creatine 250 g is the best value per serve on this list.
- If you want measured caffeine: ON Amino Energy at 100 mg a serve is easier to track than energy drinks.
- If your meals are patchy: a daily multivitamin such as Condemned Labz Multi covers the gaps.

FAQs
What supplements help students focus?
Caffeine has the best evidence for feeling less tired in the short term, as long as you keep within safe limits and away from bedtime. A multivitamin can fill gaps if your diet is patchy, and creatine is well supported for training, with small and mixed results for memory. Sleep, regular meals and water still matter more than any supplement.
How much caffeine can a uni student have in a day?
FSANZ guidance for healthy adults is no more than 400 mg of caffeine a day from all sources, with no more than 200 mg in a single serving. If you are pregnant or breastfeeding, the limit is 200 mg a day. Under 18s should have no more than 3 mg per kilo of body weight in one serving. Count coffee, energy drinks, cola and pre-workout together.
Do students need a multivitamin?
Most students who eat a varied, balanced diet do not need one, according to healthdirect. A multivitamin can be a useful safety net if you are skipping meals, eating a narrow range of foods or following a restricted diet. Choose one with sensible doses, do not double up with other vitamin products, and check with your GP if you think you are low in something specific like iron.
Can teenagers take supplements for study?
Most teenagers do not need supplements, and caffeine limits are lower for under 18s. Some products are also labelled for adults only. If you are under 18, talk to your GP or a sports dietitian before buying anything, ideally with a parent. Our supplements for teenagers guide covers what is appropriate at that age.
Is creatine good for studying?
Possibly, but do not buy it for that alone. A 2023 review of randomised trials found creatine improved memory scores compared with a placebo, but the effect was clearer in older adults than younger people and the studies were of moderate quality. Creatine has strong evidence for strength and power training, so it is best value if you also go to the gym.
