Supplements: Which Ones To Take For Your Health And Sport Performance

Caitlyn Davey • July 8, 2025

Walking through a chemist, health store or even supermarket, there can seem to be endless number of jars of vitamins promising health benefits from better sleep to glowing skin, fat loss, hair growth and reduction in inflammation to name a few. The supplements industry in general can be quite difficult to figure your way around. Sean says, “it’s a fake industry built around just trying to sell things.” And so, it is important to only go for supplements that have enough research and evidence on them to prove that they actually work. You shouldn’t blindly believe just any advertisements or the word of, say, influencers. As James says, “when it comes to the advertising on [supplements], the thing to remember for the general population is if it’s too good to be true, then it often is.”What is important to remember is that supplements are supposed to supplement your diet, not replace the nutrients that you can easily receive from food. They’re just supposed to help, but they’re not magic or a quick fix.  View this post on InstagramA post shared by Rebuild Health and Fitness (@rebuildhealthandfitness)  Supplements for healthThe coaches at Rebuild recommend a few supplements that are proven to have a positive impact on health. Some of these are fish oils, vitamin D, and whey protein.Fish oil contains two omega-3s called docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). It has cardiovascular benefits, it helps to reduce inflammation, might increase strength and size, and might improve fat loss. The amount of fish oil one’s body requires primarily depends on how much fish they eat. James says, “my advice to people is to take fish oil on the day that they don’t eat fish. I advise most people to take it.” There are also some vegetarian sources such as algae, flax seeds, and chia seeds. When it comes to supplements, the dosage depends on the goal of an individual but usually, about 300 to 1800 milligrams per day is good.Vitamin DVitamin D has become one of the most researched areas of supplements. Vitamin D is acquired and synthesised within the body when the skin comes in contact with sunlight. And so, with the ongoing pandemic, more and more people are being diagnosed with vitamin D deficiency. The problem with it is that a very small amount can be found in a person’s diet. Laughing, James says, “to get vitamin D from food, you would have to have 6,250ml worth of whole milk or a very impressive 143 large eggs per day to hit the recommended RNI.”It’s better to just get a bit of sunshine each day. A lack of vitamin D can cause various issues, including depressive symptoms. An optimal amount improves functioning of the immune system, improves bone health, potentially improves general health, and potentially improves fat loss. How much the body needs, and its dosage, depends on many things such as the skin tone, how your body functions, where you live and your ethnicity. It can be taken daily, weekly, or monthly. Ideally, people should get their blood tested first to know exactly how much is required by the body.Supplements for sport performanceHere, the boys talk about evidence-based supplements that can help with sports performance. Some of these are caffeine, creatine monohydrate, beta alanine, sodium bicarbonate, and HMB (hydroxymethylbutyrate).It is important to note that there are no fat loss supplements and as James says, “there are a few things that might facilitate it, but nothing directly helps weight lost by calorie deficit.” So, it is a better idea to focus on supplements that’ll perhaps improve performance to assist with fat loss.CaffeineCaffeine is one of the most popular supplements in the world, even if people don’t realise it. It can be found in coffee, chocolate, and various other common foods. Tolerance to caffeine increases depending on how used to it you are. And because it is so commonly consumed, figuring out what counts as a “good amount of coffee” for your body is very important.Caffeine has many performance benefits. It helps train for longer. It reduces reaction time so that makes you sharper and increases alertness. It also helps improve decision-making, especially when you are sleep deprived. Additionally, it can increase strength and force, improve muscular endurance and endurance performance. Overall, it ensures that you perform better.Ideally, it should be consumed about 60 minutes before exercise or competition. The dosage would range between one and six milligrams per kilo of body weight.When it comes to caffeine, it is extremely important to not depend on it. James says, “I think a lot of people are dependent on it. You never wanna become dependent on a stimulant to make sure you are training right.”Creatine MonohydrateCreatine monohydrate is one of the best, and arguably one of the cheapest supplements out there.It has so many benefits such as an increase in strength only after a few days of supplementing. It can help improve the overall training load compared to what could be tolerated previously and help increase muscle hypertrophy. It can also massively improve recovery. It is perhaps most useful for endurance athletes because it allows to go on for longer. It also improves cognitive function and helps with sleep deprivation. Additionally, it has been shown to increase lean tissue performance in vegetarians.It is best to take it every day and at a routine time. About 20 grams a day for five to seven days works great. Want help with your nutrition or supplements? Get in touch with Rebuild Health and Fitness to hear about our nutritional programmes.

If you live in Wynnum or Capalaba , chances are you’ve seen a bootcamp in action — high-intensity sessions in parks, with lots of burpees, sprints, and shouting. While bootcamps can be a fun way to get sweaty, there’s a reason more people are choosing structured strength training instead. At Rebuild, we often meet people who’ve jumped from one bootcamp to another, chasing results they never quite achieve, or can’t maintain. Here’s why strength training, not bootcamp-style fitness, is the smarter long-term approach for your health and body. 1. Progress Over Punishment Bootcamps often focus on burning calories and pushing people to their limits every session. It feels intense — but it’s usually random. There’s no plan beyond “go hard”. Strength training is different. It’s measured, progressive, and adaptable . Whether you’re lifting a barbell or doing bodyweight movements, the goal is to build skill, strength, and confidence over time. You're not punished for where you're at — you're coached toward where you want to be. 2. Stronger Muscles = Better Results Cardio-heavy bootcamps might help you lose weight quickly, but they rarely help you build muscle, and muscle is the key to long-term fat loss, strength, and mobility . When you train with resistance (weights, bands, or bodyweight), your body becomes more efficient. You burn more calories at rest, move better, and feel more capable in everyday life. And unlike bootcamps, strength training actually preserves lean mass while you're in a calorie deficit — which matters if your goal is body composition, not just weight loss. 3. Individual Coaching Matters Most bootcamps have one instructor yelling instructions to a big group. There’s rarely time to check your technique, let alone adjust for injuries, experience, or confidence levels. At Rebuild, our group sessions are coach-led and purpose-built . We take time to teach proper form, scale movements to your ability, and track your progress. You're not just surviving a workout — you’re learning how to move better and train smarter. 4. It’s Not Just About Today’s Workout Bootcamps often lack structure. You show up, do something exhausting, and leave. There’s no continuity or long-term planning. Strength training follows a programmed approach , meaning each week builds on the last. You’ll have sessions designed to improve specific movements and outcomes — whether that’s lifting more weight, increasing core strength, or mastering your first pull-up. That structure keeps you consistent, motivated, and injury-free. 5. Sustainability Over Shock Tactics If you’re tired of the “go hard or go home” mentality, strength training is for you. It’s adaptable to all ages, bodies, and goals . You’ll get fitter, stronger, and more confident — without burning out or breaking down. Ready to train with purpose? If you're looking for something better than a bootcamp in Wynnum or Capalaba , join us at Rebuild. We coach real people — not fitness models — to get real results. 📍 Structured training 📍 Expert coaches 📍 Community that has your back You don’t need to be fit to start. You just need to start.

A lot of people have completed a marathon but how many people have collapsed at 40km?

Sometimes you do everything right, and shit still doesn’t go to plan.
 Last weekend I ran in the Gold Coast Marathon, my first ever marathon. I trained properly, my body felt relatively good (all things considered when preparing to run 42.2km), I carb-loaded, and my race day nutrition was dialled in.
 I was ready.
 We set off. Jess and the kids met me at different points on the course with signs, the atmosphere was great. I loved seeing the kids with their signs. Pacing felt on point. The first 21km? Easy. I felt great. Maybe I should’ve drunk more water, but I didn’t think too much of it at the time.
 At 25km, I felt slower, but pace wise I was still holding well. I’d kept telling myself throughout the day "The race starts at 30km." And let me tell you, it does.
 By 30km, the sun was out, and I was starting to struggle. My watch started glitching so I had no real idea of my splits. I thought I was slowing down a lot (turns out I wasn’t), but the effort to keep the same pace suddenly felt 10x harder.
 I hadn’t taken on enough water. Usually, I can get away with lower fluids. Not this time. Dehydration crept in. hard.
 At 35km I was in survival mode, one foot in front of the other, flicking between moments of pain and little short lived waves of “let’s go.” But by 39km I was delirious. I could see the finish line, I hit the 40km mark (where I thought enjoyment might return to finish), and I collapsed.
 I was gone. Scary stuff.
 The last few hundred metres were a complete blur. All I remember is the crowd, the medics, and about five paramedics suddenly around me. I was vomiting, shaking, confused, in and out of it. I had this overwhelming, indescribable feeling, and honestly, for a moment, I thought I could die.
 My memory went. I couldn’t recall the day, the year, where I lived, or how to spell. I only knew who Jess and the kids were, and that I didn’t want them to see me with wires in me. 
 My temperature had hit 40°C. Blood pressure crashed. Thankfully, the medics and paramedics were incredible, I had a drip running into me within 10 to 15 minutes.
 As I already knew, I’m stubborn. I wanted to run it all. Not walk. Not stop and breathe and In hindsight, I should have. 
 Seems like my mind was just a bit stronger than my body on the day. I never thought I could push myself there in all honesty. 

Am I gutted? Of course, I was only 2km away but I gave it everything I had on that day. Heat stroke, exhaustion, and dehydration got me. 

I am always reminded here of the quote ‘The man in the arena’ look it up if you need. 
 Will I run 42.2km again? Yes, I feel I need to. 

Would I do things differently, now I’ve run 40km under race conditions? You bet, lessons learnt. Always lessons. Never be scared to not succeed. Be scared to never try in the first place. 
 We go again.
