The Runner’s Supplement List: What Works & What’s Hype

There’s no doubt that supplements have come a long way from the early days of "bro-science" and speculative evidence. I still remember a time before social media when we’d pore over magazines to see what the fittest athletes were taking, never once stopping to think, "Hey, maybe they’re just getting paid to say this." For some reason, we just trusted the opinions of whoever had the physique or the race results we wanted.

Social media has only made this worse. At the time of writing, the FDA reports there are more than 10,000 supplements on the market. That isn’t a typo. Nutritionists generally agree we should eat around 20 different foods a day, or at least 30 unique plants a week - to get a healthy dose of nutrients. Yet somehow, as of 2022, 66% of Australians are considered overweight or obese. It begs the question: Are we horrible at following advice, or is the advice just wrong?

From the athletes we coach at Wild Blue, most come to us either to hit a specific race target or just to get "healthier." They aren’t elites; they’re everyday people looking to better themselves. Ironically, they are also the primary target for the supplement industry. If the average Australian is spending $427 on supplements annually, we need to know: What is actually worth our money?

Australian Vitamin & Supplement Spend per Generation

...So a question we think we should answer is, what is actually worth our money?

To find the answer, we went deep into the 2026 ISSN (International Society of Sports Nutrition) Position Stand on Dietary Antioxidants. It’s a massive 50-page review that essentially audits everything we put in our bodies to "get faster."

Below is the breakdown of the top 10 things runners need to know, from the "must-haves" to the ones that are literally stopping your progress. It's s also worth noting that I'm a run-coach, not a doctor. We’ve spent years studying human movement and the science of performance, but you should always chat with your GP before starting a new supplement routine, especially if you have underlying health stuff going on.

1. Creatine Monohydrate (The Heavy Hitter)

Most runners still think creatine is just for bodybuilders trying to get "huge." The 2026 data shows otherwise. It is one of the most effective ways to support brain health and neuromuscular recovery. If you want your brain to talk to your feet more effectively during those hill sprints, this is top-tier.

• The Dose: The paper recommends 0.1g per kg of body weight daily. If you’re a 70kg runner, that’s 7g, not the standard 3g scoop you see on most tubs.

2. Omega-3 Fatty Acids

Think of these as your internal anti-inflammatory insurance policy. For the everyday runner dealing with the "rusty gate" feeling in the morning, Omega-3s support heart health and joint mobility without the side effects of over-the-counter painkillers.

• The Dose: Aim for 1–2g of combined EPA and DHA every day.

3. Tart Cherry

The 2026 study highlights Tart Cherry as a powerhouse for reducing muscle soreness. The best part? Unlike some anti-inflammatories, it doesn't seem to blunt your body’s natural ability to get stronger after a run.

• The Dose: 240–350ml of juice or 480mg of powder, twice a day, around your hardest sessions or races.

4. Astaxanthin

This is a potent antioxidant found in algae and seafood. It helps protect your cells from the "rust" (oxidative stress) of heavy training blocks. It’s becoming a favourite for runners who want to protect their "Hardware" without the downsides of synthetic vitamins.

• The Dose: 4–12mg per day, ideally taken with a meal that has some fat in it.

5. Whole Food Polyphenols (Berries over Pills)

The study was very clear: you can’t out-supplement a bad diet. Getting your nutrients from dark berries, cocoa, and leafy greens provides a "cocktail" of benefits that a single pill just can’t replicate.

• The Logic: If it’s deep purple, dark green, or bright red, it belongs on your plate. Aim for 1-2 cups of mixed berries daily.

6. Vitamin D (The Australian Paradox)

This isn't just in the ISSN paper; it’s a reality for us in Australia. Despite the sun, about 25% of Australians are Vitamin D deficient. For runners, low Vitamin D means fragile bones and weaker muscles.

• The Advice: Get a blood test before you supplement, but if you live in the southern states, don't assume the yearly trip to the Gold Coast sun is doing all the work for you.

7. Magnesium (For the Twitchy Runner)

While the ISSN paper focuses on antioxidants, magnesium is the silent partner in recovery. It’s involved in over 300 reactions in your body, including muscle relaxation and sleep. If your legs feel "restless" at 3:30 PM, you might be low.

• The Form: Look for Magnesium Glycinate for better absorption and less "tummy trouble."

8. Electrolytes

In a country where a "cool morning run" can be 24 degrees, electrolytes are non-negotiable. But forget the sugary "sports drinks." You need sodium to keep your electrical system firing so your "Software" doesn't glitch out 10km into a long run.

• The Strategy: Focus on sodium-heavy mixes, especially if you find salt crusting on your face after a run.

9. Probiotics

The 2026 review touches on how a healthy gut reduces the "upper respiratory tract infections" (the classic runner’s cold) that pop up during heavy training. If you’re constantly getting sick after a big race, your gut might be the missing link.

10. The Dangers of TOO Much Vitamin C & E

This is the most controversial part of the study. Taking massive, chronic doses of Vitamin C (1000mg+) and Vitamin E (400 IU+) in pill form can actually "blindfold" your muscles. It stops your body from sensing the stress of the run, which means your body doesn't bother getting faster or stronger.

• The Takeaway: Eat your oranges; don't take the mega-dose pills unless you're actually sick.

The Bottom Line

We spend a lot of time (and money) looking for the "magic pill" that will shave two minutes off our 5km. But the science in this 2026 ISSN report is pretty clear: supplements are the final 1%.

If you’re tipping back $427 worth of powders every year but you’re still moving like a "rusty gate" or ignoring your basic mechanics, you’re essentially putting premium fuel into a car with square wheels.

Focus on the way you move, eat your berries, take your creatine, and let the rest of the 10,000 supplements on the market be someone else’s expensive hobby.
