Gnarly Nutrition is one of the most trustworthy smaller sports nutrition brands we have looked at: every supplement carries NSF certification, many products are NSF Certified for Sport, and the formulas avoid proprietary blends. It is a premium-priced, athlete-focused brand, but the transparency and sample box make it easy to recommend.
What we like
- All supplements NSF certified, with many NSF Certified for Sport for tested athletes
- Creatine uses Creapure, a well-regarded branded creatine monohydrate
- Clean labels without proprietary blends or artificial sweeteners, per the brand
- Sample Box and a short quiz make it easy to try before committing
- HSA/FSA eligible shopping and moves toward glass and steel packaging
Keep in mind
- Premium pricing compared with mass-market sports nutrition
- Smaller flavor selection than big protein brands
- Some products contain caffeine or adaptogens that will not suit everyone
- Shipping thresholds are not prominently stated on the homepage
Gnarly Nutrition grew out of the Salt Lake City outdoor scene, and it still feels like a brand made for people who spend weekends on rock, trail or snow rather than on stage. Its lineup covers the basics of training nutrition, from whey and vegan protein to creatine, electrolytes and a small Baseline vitamin range, with an unusually strong emphasis on third-party certification.
We looked at the company's background, its certifications, the core products and how to build a simple routine from them. If you care about knowing exactly what is in your supplements, particularly if you compete in tested sport, Gnarly is worth a close look.
Where Gnarly comes from
Gnarly was started roughly a decade ago by a small group in Salt Lake City, Utah. Chief executive Eli Kerr previously spent about ten years as an outdoor recreation therapist working with adolescents, and the founding idea was to make natural, good-tasting supplements for functional athletes rather than bodybuilders.
A few years after launch, the company brought in Shannon O'Grady, who holds a doctorate in biology and has decades of supplement industry experience, as chief product officer. Her arrival pushed the brand toward science-led formulation and education, and the product range has since roughly tripled. Gnarly has partnered with USA Climbing and runs its own podcast, and it has been steadily moving packaging away from plastic toward glass and recyclable steel.
Why the certifications matter
Supplements in the US are not approved before sale, so independent certification is one of the best signals a buyer has. According to Gnarly, all of its supplements carry NSF certification, which verifies that what is on the label is in the product and screens for contaminants. Many products are also NSF Certified for Sport, which adds screening for substances banned in sport.
That matters most to athletes subject to drug testing, but it is reassuring for anyone. Gnarly also says it avoids proprietary blends, artificial sweeteners and synthetic colors, using sweeteners such as stevia and monk fruit and caffeine from green tea where caffeine is included.

The core lineup
Protein
- Grass-Fed Whey Protein: a smooth, mixable whey that the brand says works with just water; it has picked up industry recognition, including a Good Housekeeping fitness award.
- Vegan Plant Protein: a dairy-free blend built on pea protein with additional plant sources and enzymes.
- Collagen Pro: a collagen formula aimed at connective tissue support.
Performance and recovery
- Creatine: made with Creapure creatine monohydrate.
- Hydrate: an electrolyte mix with sodium, potassium and magnesium, in flavors including Cherry Limeade.
- Fuel2O and Essential Aminos for during and after training.
- Pre-workout: part of the Gnarly System, with caffeine from green tea plus ingredients such as beta-alanine and citrulline.
- Performance Greens for everyday nutrition.
Baseline vitamins
A small foundational range: Iron+, Magnesium Glycinate, Omega-3 and Vitamin D3.
Building a simple routine
Gnarly organizes its training products as the Gnarly System: something before activity, something during, and something for recovery. You do not need all of it. A practical starting stack for most active adults looks like this:
- Protein after training, whey or vegan depending on your diet, to help you reach your daily protein target.
- Creatine daily, at the dose on the label, for strength and power work such as climbing or lifting.
- Hydrate on long, hot or sweaty days, when you are losing more sodium than water alone can replace.
The pre-workout and greens are optional extras. If you are unsure where to begin, the Sample Box and the brand's two-minute quiz let you try several products before buying full sizes.
How Gnarly compares with bigger sports brands
Mass-market sports nutrition brands tend to win on price, flavor variety and availability in big-box stores. Many of them also offer certified products, but certification is often limited to a handful of lines. Gnarly flips that model: a narrower catalog where certification is the default rather than a premium tier.
The other difference is tone. Gnarly's education and product design are aimed at endurance and skill athletes, such as climbers, skiers, trail runners and cyclists, rather than physique goals. That shows in the emphasis on hydration, recovery and foundational nutrients like iron, magnesium and vitamin D, which are common gaps in hard-training outdoor athletes.
If you mainly want the cheapest protein per gram, a warehouse brand will win. If you want to be confident about what you are taking, especially before a tested competition, Gnarly's approach is easier to trust.
Pricing and buying tips
Gnarly sits in the premium tier of sports nutrition, comparable with other certified, clean-label brands rather than budget warehouse tubs. You are paying for certification, branded ingredients like Creapure and smaller-batch production.
- Sign up for email to get 10% off a first order.
- Many products can be bought with HSA or FSA funds, which effectively lowers the cost if you have those accounts.
- Orders ship with tracking; check checkout for current shipping rates and any free-shipping threshold.
- Limited-edition flavors, such as non-alcoholic Salted Margarita and Piña Colada drink mixes, appear seasonally.
Who it suits and our verdict
Gnarly is an excellent match for drug-tested athletes, outdoor endurance athletes, and anyone who wants simple formulas with real third-party verification. It also suits people with food sensitivities, thanks to dairy-free options and minimal additives. It is less suitable for bargain hunters or people who want a huge choice of dessert flavors.
Our verdict: Gnarly Nutrition earns its strong reputation through certification, transparency and genuinely athlete-focused products. Start with the Sample Box or a protein and creatine pair, and add Hydrate when your training gets long or hot.
