๐ŸŠโ€โ™‚๏ธ What Supplements Actually Work for Swimmers? A Breakdown of the Latest Research

In the world of competitive swimming โ€” even at the Masters level โ€” athletes are always searching for the edge that gets them stronger, faster, and more resilient. But when it comes to sports supplements, it can feel like youโ€™re drowning in hype and conflicting advice.

A 2025 systematic review has cut through the noise, analysing 23 peer-reviewed studies involving 422 competitive swimmers across events from 50m to 800m. Hereโ€™s what the science actually says โ€” and how Masters swimmers can apply it.

๐Ÿง  The Takeaway: Which Supplements Are Worth It?

โœ… Creatine

Best for: Sprint & mid-distance events
Creatine consistently shows ergogenic benefits, helping swimmers enhance power output and recovery. This is especially useful for Masters athletes balancing intensity and longevity.

โœ… Caffeine

Best for: All distances
Administered at 3โ€“6 mg/kg bodyweight ~60 minutes pre-race, caffeine was linked with statistically significant performance improvements. The key? Timing and dosing โ€” both critical to avoid side effects or missed benefits.

โš ๏ธ Sodium Bicarbonate & ฮฒ-Alanine

Best for: Longer races (200mโ€“800m)
These buffering agents may help reduce lactic acid accumulation. While results are promising, individual response can vary โ€” so test during training, not on race day.

โŒ Beetroot Juice & Citrulline/Arginine

Best for: None (yet)
Despite popularity in endurance sports, these supplements didnโ€™t show meaningful performance gains in swimmers based on current data. Future studies may change that, but for now: low ROI.

๐Ÿ‘ฅ What This Means for Masters Swimmers

As a Masters athlete, your goals might include performance, longevity, and consistency โ€” not just shaving tenths off your time. Supplements like creatine and caffeine offer measurable support, but should always be integrated with proper strength training, sleep, and periodised nutrition.

If youโ€™re not sure where to begin, get a personalised supplement strategy aligned with your race calendar and training phase.

This study reinforces the value of smart, individualised supplementation โ€” especially when combined with solid coaching and recovery strategies. Itโ€™s not about taking more, itโ€™s about taking what actually works, when it works.

For Masters swimmers who want every edge, science-backed support is now non-negotiable.
