Pros and cons
Sport Organic Plant-Based Protein
- 30 g of protein and about 2.5 g of leucine per serving, high for a plant protein
- NSF Certified for Sport, USDA Organic, Non-GMO Project Verified and NSF gluten-free certified
- Vegan and made without dairy or soy ingredients
- Reasonable cost per gram of protein when bought on Amazon
- Taste and texture are divisive; reviewers mention chalkiness, foam and a stevia aftertaste
- Recovery blend amounts are not disclosed
- 460 mg of sodium per two-scoop serving
- Some buyers dislike recent formula and flavor changes
Gold Standard 100% Whey
- 24 g of protein in a 120-calorie, 31 g scoop (about 77% protein by weight)
- Informed Choice certified and regularly tested for banned substances
- More than 20 flavors on the brand's US store, with consistently strong feedback on taste and mixability
- Fully disclosed ingredient list with no proprietary blend
- Widely available on Amazon, TikTok Shop and at major retailers
- Sweetened with acesulfame potassium and uses artificial flavors
- Contains whey concentrate, and a share of buyers report digestive discomfort
- No longer cheap: about $1.39 per serving at typical retail prices for the 5 lb tub, and the brand-site list price is higher
- Servings per tub vary by flavor (roughly 68 to 75 in 5 lb-class tubs), which complicates price comparisons
Our verdicts
Sport Organic Plant-Based Protein
For vegan or dairy-free athletes who need certified sport nutrition, this is the plant protein to beat: 30 g of protein per serving, solid leucine and four third-party certifications. Its flavor and texture are divisive, so buy a single tub before committing to a subscription.

Gold Standard 100% Whey
Gold Standard 100% Whey remains a default recommendation for good reason: a lean 24 g protein dose, banned-substance certification, and taste and mixability endorsed across about 100,000 buyer ratings. It is no longer a bargain, and the concentrate and artificial sweetener will not suit everyone, but few powders balance quality, variety and availability this well.
