The most useful supplements for tradies are simple ones: an electrolyte drink for hot days, a protein top-up for long shifts and, if your knees are complaining, a collagen powder with realistic expectations. None of them replace water, proper meals and safe work habits, but they can make a long day on the tools easier. Here is what is worth buying in Australia, what the evidence actually says and what to skip, with prices in AUD.

Prices are at the time of writing. If you only buy one thing before summer, make it an electrolyte mix for the days you sweat through your shirt by smoko.
Working in heat: know the risks first
Heat is a genuine safety issue on site, not just discomfort. Safe Work Australia's guide to managing the risks of working in heat explains that heat-related illness happens when your body has to work too hard to keep cool. The guide says employers must give workers access to cool drinking water, and workers should take more regular breaks and ease off the pace in the heat. It also points out that thirst is satisfied before your fluid losses are fully replaced, so you cannot rely on thirst alone.
Know the warning signs of heat stroke from the same guide: a body temperature above 39°C, confusion, irritability or poor judgement, headache, dizziness, nausea, and in some cases no sweating at all. Heat stroke is an emergency. Call 000, move the person somewhere cool and start cooling them while you wait. Getting used to the heat helps your body sweat more efficiently, but Safe Work Australia warns this is not a reliable control on its own.
Hydration: water first, electrolytes when you sweat
Water should be your main drink all day. When you are sweating heavily for hours, you also lose salt, and that is where an electrolyte drink earns its place. Safe Work Australia's first aid advice for dehydration is to use oral electrolyte drinks that contain salt and potassium, and to drink an electrolyte solution for heat cramps. It also advises avoiding caffeinated, carbonated and alcoholic drinks and salt tablets when someone is dehydrated.
- Dr. Hydrate Electrolytes is our best-selling electrolyte over the last six months. Each 9 g scoop has 250 mg sodium, 160 mg potassium, 160 mg calcium and 63 mg magnesium, with no added sugar, and the jar holds 30 serves for $49.95, about $1.67 a bottle. The brand states it is HASTA certified.
- R1 Lytes+ gives 200 mg sodium and 220 mg potassium per scoop with no stimulants, 40 serves for $39.95.
- R1 Lytes 10 serves is a small tub for $10.00, handy for the glovebox or toolbox if you want to try electrolytes before buying a full tub.
Mix one serve into a large bottle of cold water and sip it through the hottest part of the day, alongside plain water. For more detail, read our hot weather hydration and electrolytes guide, compare options in our best electrolytes guide or browse the full hydration and electrolytes range.
Protein for long days on the tools
Early starts, a servo pie at smoko and a late dinner can leave you short on protein, especially if you also train after work. The ISSN protein position stand suggests active people aim for roughly 20 to 40 g of protein per meal, spread every three to four hours. Real food comes first: eggs, tuna, chicken, yoghurt and milk all work. A shake is simply the easiest way to fill a gap when you are on site.
Next Generation Protein Delicious 1.25 kg is Australian made and gives 24 g of protein per 28 g serve (Chocolate), with 44 serves for $99.95. That is about $2.27 a shake at the time of writing. Put a scoop in a dry shaker in the morning and add cold water at smoko. Keep the powder out of the sun on the dash. See more in our whey protein range.
Joint support: what actually helps
Kneeling, lifting and climbing ladders all day takes a toll. Be honest with yourself about what helps most: good lifting technique, knee pads, a few minutes of warm-up and regular strength training for your legs and back. Supplements come a distant second.
Collagen has the most interesting early research. In a 2017 study by Zdzieblik and colleagues, 139 young athletes with knee pain during activity took 5 g of a specific hydrolysed collagen a day for 12 weeks and reported less pain during activity than the placebo group. The study used one branded collagen ingredient and was funded by the company that makes it, so the results may not carry over to every collagen powder. The AIS rates collagen support as Group B, meaning the evidence is emerging but not yet strong.
If you want to try it, R1 Collagen by Rule 1 gives 10 g of hydrolysed bovine collagen, 80 mg of hyaluronic acid and 90 mg of vitamin C per scoop, with 25 serves of Unflavoured for $54.95. Give it at least eight to twelve weeks before you judge it. Our post comparing collagen, glucosamine and omega-3 for joints covers the other options, and you can browse the full bones and joints range. If a joint is swollen, locking or painful for more than a couple of weeks, see your GP or a physio rather than reaching for a supplement.
Energy: food and sleep beat any tub
Most tradies run on coffee, and that is fine for alertness. Just do not count it as your hydration in the heat, and keep energy drinks for the occasional day rather than your daily water bottle. Steady energy on a long shift comes mostly from a proper breakfast, a decent lunch with carbs and protein, and enough sleep. Save stimulant pre-workouts and fat burners for the gym, not a hot roof.
Our pick for tradies
If you work outdoors, start with Dr. Hydrate Electrolytes for summer and keep an R1 Lytes 10 serve tub in the ute as a backup. Add Next Generation Protein Delicious if your meals are rushed or you train after work. Try R1 Collagen only if your joints are a real issue, and think of it as a trial rather than a fix. Order online with Australia-wide delivery, or use click and collect at a store near the job.

FAQs
What supplements should tradies take in summer?
Start with plain water and an electrolyte drink for the days you sweat heavily. Safe Work Australia's heat guide recommends drinks containing salt and potassium for dehydration and an electrolyte solution for heat cramps. A protein powder helps if your meals are rushed. Everything else is optional. No supplement replaces shade, regular breaks and knowing the warning signs of heat illness.
Are electrolyte drinks better than water for working outside?
Not instead of water, but alongside it. Water should be your main drink, because most of what you lose in sweat is fluid. When you sweat heavily for hours you also lose salt, and an electrolyte drink helps replace it. A sensible approach is plain water through the day plus one or two bottles of an electrolyte mix during the hottest stretch of work.
Do joint supplements actually work?
The evidence is mixed and mostly early. Collagen has some promising studies, such as a 2017 trial where young athletes taking 5 g of a specific hydrolysed collagen a day reported less knee pain during activity, but the AIS still rates collagen support as Group B. Good technique, knee pads and leg strength training usually help more. If pain lasts more than a couple of weeks, see your GP or a physio.
Are energy drinks okay to drink on site?
An occasional energy drink is fine for most healthy adults, but it should not be your hydration drink on a hot day. Safe Work Australia's first aid advice for dehydration is to avoid caffeinated, carbonated and alcoholic drinks. Count every coffee and energy drink in your daily caffeine, and keep a water bottle and an electrolyte mix in the ute for the hottest days.
How much protein does a tradie need?
It depends on your size, workload and whether you also train. A practical target for active people is about 20 to 40 g of protein at each meal, spread every three to four hours, as the ISSN suggests. If breakfast is a coffee and lunch is a pie, a protein shake at smoko is an easy fix. Eggs, tuna, chicken, yoghurt and milk work just as well.
