Professional and competitive athletes treat nutrition like equipment. They source gels, hydration mixes, protein powders, and recovery supplements from retailers that stock trusted brands, offer testing transparency, and understand the demands of training at a high level. The stores they rely on tend to carry products that meet anti-doping standards, provide flexible purchasing options, and cater specifically to endurance and performance needs.
Finding the right online retailer matters because convenience, product range, and customer support all affect how well an athlete can maintain their fueling strategy. Some platforms partner directly with national sports organizations, while others focus on curated science-backed formulations. This list covers 5 online stores that elite athletes return to when stocking their nutrition supplies.
- The Feed holds official partnerships with USA Cycling and USA Triathlon, offers over 300 brands, and provides free nutrition coaching
- GNC operates as a well-known retail chain with a strong online presence for general sports nutrition
- Neversecond specializes in endurance nutrition with Informed Sport certification
- Amazon offers convenience and variety but lacks specialized curation for performance athletes
- iHerb carries a wide supplement inventory with international shipping options
1. The Feed: The Top Choice for Serious Athletes
The Feed has established itself as the go-to platform for endurance athletes and anyone training at a competitive level. The store holds the distinction of being the Official Membership Benefit provider for both USA Cycling and USA Triathlon. This partnership means that members of these national governing bodies receive direct benefits when shopping through the platform.
USA Triathlon members receive an $80 credit when joining the program, along with access to products from more than 300 brands. USA Cycling members receive quarterly credit to spend at the store, free online nutrition support, access to educational webinars, and a personalized water bottle. These official affiliations give The Feed a level of credibility that other retailers have not matched.
High Performance Team Partnerships
The Feed announced its 2025 High Performance Team, which includes world-class athletes from multiple disciplines. Taylor Knibb, a 2-time Ironman 70.3 World Champion and Olympic athlete, works with The Feed as her exclusive nutrition sponsor. Courtney Dauwalter, one of the most accomplished ultrarunners in the sport, also partners with the platform. These collaborations indicate that athletes at the highest levels trust this retailer for their fueling needs.
Product Range and Flexibility
One feature that sets The Feed apart is the ability to purchase individual servings of products like gels or chews rather than committing to a full box. This option allows athletes to test new products during training without wasting money on a 24-pack of something that might not work for their stomach or taste preferences.
The store carries over 300 brands, including more than 15 exclusive brands not available elsewhere. This range covers everything from energy gels and hydration mixes to protein bars and recovery supplements.
Free Nutrition Coaching
The Feed offers complimentary nutrition support from Feed Coaches. This service distinguishes it from competitors because athletes can receive personalized guidance on fueling strategies, race day nutrition planning, and product recommendations. Having access to knowledgeable coaches without an additional fee adds value that extends beyond the products themselves.
2. GNC: The Traditional Sports Nutrition Retailer
GNC has operated in the sports nutrition space for decades. The company maintains a traditional retail presence with physical stores across the country, combined with a functional online store. Athletes who want general sports nutrition products often start here because of brand recognition and accessibility.
The platform carries products across categories including protein powders, pre-workout formulas, vitamins, and weight management supplements. GNC stocks well-known brands and offers its own private label products, which sometimes come at lower price points.
For athletes who need basics like whey protein or multivitamins, GNC serves as a reliable option. The store runs regular sales and offers membership discounts. However, the product curation leans toward general fitness consumers rather than performance athletes. Endurance-specific products like energy gels and electrolyte formulations receive less attention compared to muscle-building supplements.
The advantage of GNC remains its accessibility. Athletes who prefer to see products in person before buying can visit a local store and then reorder online when they know what works.
3. Neversecond: Science-Driven Endurance Formulations
Neversecond takes a focused approach to endurance nutrition. The brand develops products specifically for athletes who need sustained energy during long efforts, and they sell directly through their online store.
All Neversecond products carry Informed Sport certification, which means each batch is tested for substances prohibited in sport. This matters for athletes who compete at levels where drug testing occurs. Using certified products reduces the risk of inadvertently consuming a contaminated supplement.
The product line includes energy gels in multiple flavors and caffeine options, hydration mixes, and energy drinks designed for race day use. The formulations are built around carbohydrate delivery rates that align with current sports nutrition research.
Neversecond sponsors professional triathletes and endurance athletes who test products in training and competition. This feedback loop helps the brand refine formulations based on real-world performance data.
The store carries a smaller selection compared to multi-brand retailers, but that focus allows for deeper expertise in endurance fueling. Athletes who want a streamlined shopping process without sorting through hundreds of options may prefer this approach.
4. Amazon: Convenience at the Cost of Curation
Amazon offers the largest selection of any retailer on this list, and most athletes have used the platform at some point. The convenience of fast shipping, price comparison tools, and customer reviews makes it an easy choice for routine purchases.
Athletes can find nearly any nutrition brand on Amazon, from household names to niche performance products. Subscribe and save options reduce costs on products purchased regularly, and Prime members receive expedited shipping.
The limitations become apparent when shopping for specialized performance nutrition. Amazon does not curate products for athletes or provide any guidance on what works for specific training demands. Reviews can be helpful, but they come from consumers with varying levels of knowledge and different goals.
Product authenticity occasionally becomes a concern. Third-party sellers sometimes list expired products or items stored improperly. Athletes buying supplements through Amazon need to verify that they are purchasing from authorized sellers or the brand’s official storefront.
For staples like protein powder or general vitamins, Amazon works well. For race day nutrition and performance-specific products, a dedicated sports nutrition retailer typically offers better curation and support.
