The most effective sports performance supplements are those backed by science and tailored to an athlete’s specific needs. For endurance athletes such as triathletes, proven options include beetroot extract for circulation and stamina, amino acids for recovery, and anti-inflammatory compounds like tart cherries.
While no supplement can replace disciplined training and a balanced diet, carefully chosen products can support energy, recovery, and resilience. In short, the right supplements to take for athletes are those that are safe, third-party tested, and proven to enhance performance.
The Challenge of Navigating the Supplement Market
With thousands of sports performance supplements lining store shelves and online marketplaces, it can be difficult for athletes to determine what actually works. Unlike prescription medications, supplements are not closely regulated before hitting the market. Labels may not always tell the full story, and exaggerated marketing claims can be misleading.
This is why companies like Sur Nutrition stand out. Every product is built on scientific research, designed for endurance athletes, and tested for purity and safety. For triathletes specifically, Sur has developed endurance supplements for triathletes that are plant-based, bioavailable, and formulated to deliver measurable results without unnecessary fillers.
The Upside of Supplements for Athletes
Athletes place heavy demands on their bodies, and it’s nearly impossible to meet every nutritional need through diet alone. Strategic supplementation can help bridge the gap. Here’s how:
-
Micronutrient support: Vitamins and minerals like iron, magnesium, and B12 are critical for energy metabolism and endurance. Deficiencies can hinder training progress and increase fatigue.
-
Macronutrient reinforcement: Protein powders and amino acid supplements help repair muscles and support lean tissue growth after long workouts.
-
Performance-boosting compounds: Specific supplements like nitrates can provide tangible performance gains.
When combined with balanced nutrition and training, these supplements create the foundation for sports performance supplements that deliver lasting benefits.
Key Supplements That Actually Work
Not every supplement lives up to its claims. But several categories are well-supported by research and widely used by athletes around the world.
1. Branch-Chain Amino Acids (BCAAs)
BCAAs are essential for reducing muscle breakdown and accelerating recovery. They can:
-
Decrease soreness after long or intense sessions
-
Provide an additional energy source during endurance efforts
-
Support lean muscle mass in calorie-deficit training blocks
Sur’s Organic Meal Shake incorporates a variety of plant-based proteins to create a complete amino acid profile, improving digestibility and effectiveness compared to single-source proteins.
2. Beetroot and Nitrate Supplements
Few supplements have garnered as much attention in endurance sports as beetroot. Rich in nitrates, beetroot supports vasodilation, enhancing blood flow and oxygen delivery to muscles. This leads to:
-
Improved stamina
-
Longer time to exhaustion
-
Greater oxygen efficiency
Sur offers two beetroot-based options:
-
Organic beetroot capsules: A natural source of circulation and energy support.
-
AltRed beetroot extract: A concentrated, bioavailable form that works synergistically with your body’s own nitrates for sustained endurance.
For triathletes, these are some of the most effective endurance supplements for triathletes available today.
3. Tart Cherries and Calcium Fructoborate
Recovery is just as important as performance. Tart cherries are rich in antioxidants and polyphenols that combat exercise-induced inflammation, reduce pain, and support faster recovery.
Sur’s Joint Support formula combines tart cherries with calcium fructoborate, a compound found naturally in fruits and vegetables that has been shown to support bone density and reduce inflammation.Together, these ingredients provide athletes with joint protection and recovery support, key for those logging long training sessions.
Why Athletes Trust Supplements
Studies confirm that many athletes rely on supplements to enhance performance and recovery. For instance:
-
International studies show that two-thirds of elite track and field athletes use supplements.
-
Surveys among US military personnel found that 41% of men and 36% of women used energy supplements, highlighting their widespread adoption among performance-driven populations.
Supplements are not shortcuts, but they can be strategic tools. For triathletes facing high training volumes, well-chosen supplements provide resilience against fatigue, injury, and burnout.
Be an Informed Consumer
Despite their benefits, supplements must be approached carefully. In 2024, the FDA issued warnings about bodybuilding products containing unlisted steroids that caused serious health issues. This highlights why transparency and testing are crucial.
Here are steps athletes should take when evaluating supplements to take for athletes:
-
Check third-party certifications such as Informed Sport, which verifies product safety and purity.
-
Review research evidence to confirm that a supplement has proven benefits.
-
Read the ingredient label carefully to avoid hidden fillers, artificial additives, or banned substances.
Sur Nutrition prioritizes these principles, ensuring athletes get clean, effective supplements with every product.

Supplements That Actually Work
So, do supplements really help athletes unlock their potential? The answer is yes, when they are chosen carefully, used responsibly, and supported by science. The best supplements to take for athletes are those that:
-
Enhance endurance (beetroot and nitrates)
-
Reduce fatigue (BCAAs)

Support recovery (tart cherries, calcium fructoborate)
