This guide compares four protein powders for gluten-free shoppers:

1. Garden of Life Raw Organic Protein Vanilla — an organic plant blend.
2. Vega Protein + Recovery Vanilla — a plant powder with 30g protein per labeled serving.
3. Transparent Labs Whey Isolate Vanilla Peanut Butter — a whey option with peanut flour and stevia.
4. Optimum Nutrition Gold Standard 100% Whey — a broad whey range, with our exact Extreme Milk Chocolate 5 lb label check still incomplete.

Two are plant powders; two are whey options. We compare what you get, which routine each fits, and what would make us choose something else. Start with the two tables for the short answer; the individual sections below explain our reasoning.

Our starting choice for everyday plant protein is Garden of Life Vanilla, if sesame and its sweeteners suit you: its exact-item gluten-free documentation and lower protein cost give it the clearest combined case here. For whey shoppers who want peanut-butter flavor and stevia, Transparent Labs is worth shortlisting. Its exact-variant label is more fully documented in our review than the targeted Optimum Nutrition pack; that is an evidence advantage, not proof of better recovery results.

The direct comparison: reasons to choose—and reasons to pass

Formula highlights are not full ingredient or allergen lists. The reviewed products have different levels of gluten-free evidence; a sport-testing logo does not substitute for gluten-free certification. Product-specific details follow below.

Price comparison: what does the protein actually cost?

The cost of one shake and the cost of the protein in it are different comparisons.

Optimum Nutrition is a retailer-listing comparison: iHerb’s U.S. listing identifies the flavor, 5 lb pack, UPC 748927024142, displayed price and 71 servings. Manufacturer confirmation of the current 5 lb label remains outstanding. These calculations apply to that listed configuration, not every tub shipped.

Prices checked October 24, 2026: manufacturer listings for Garden of Life, Vega and Transparent Labs; retailer iHerb for Optimum Nutrition. USD, before tax and delivery; subscription discounts excluded. Displayed prices are not checkout quotes. The 25g figure is a comparison unit, not a prescribed serving.

At these prices, Garden of Life costs about 19% less for the same protein quantity. Vega’s larger serving narrows the gap suggested by the tub prices, but does not erase it.

Among the three manufacturer-matched price entries, Transparent Labs has the lowest cost per 25g protein, at about $1.93. ON’s retailer-listed configuration is lower still, at about $1.69, but requires a $114.99 upfront purchase and retains the label qualification above. Garden of Life remains the lower-cost plant option. These figures compare protein quantity, not taste, protein quality or digestion. For the calculation and a worked example, see how to compare protein powder prices.

Want the reasoning? Here is a closer look at each powder

Garden of Life: our everyday plant pick

Choose it if you want an organic plant powder and value clear gluten-free documentation. Raw Organic Protein Vanilla, item 658010116039, provides 22g protein per 33g scoop, with about 20 servings in the package reviewed.

Its pea, sprouted-grain and seed blend makes it relevant to shoppers avoiding dairy. The important exception is sesame: plant-based does not mean free of other allergens. Erythritol and stevia are also part of this formula, so this is not an unsweetened option.

Garden of Life confirmed to RecoverFitNow on October 13, 2026 that its current Raw Organic Protein products are NSF Certified Gluten-Free. The exact Vanilla label it supplied carries that mark. This is stronger evidence for our gluten-free buying decision than a vague “tested for quality” statement.

Choose another option if: you avoid sesame, erythritol or stevia, or specifically want a whey powder.

Vega: more protein per scoop, at a higher price

Choose it if a 30g plant-protein serving suits your routine. Vega Protein + Recovery Vanilla uses pea, pumpkin and sunflower proteins and includes stevia. Its U.S. page markets it as vegan and gluten-free.

The larger protein serving is convenient if that is the quantity you want from your shake. It also comes from a larger scoop: the reviewed 829g, 19-serving label lists 43.6g per serving, 190 calories and 30g protein. Garden of Life’s scoop is 33g. Comparing only the protein number hides part of the difference.

Vega is the more expensive purchase in our comparison, even after allowing for the extra protein. We would pay the premium for a specific preference that matters in daily use, rather than assuming “Recovery” in the name means a better result.

If sport certification is your reason to buy, pause at this detail: the NSF record we found lists different package and serving specifications from this tub. We cannot treat that record as confirmation of the current 829g version. The precise mismatch is documented in the research notes below.

The manufacturer’s facility warning includes milk, soy, peanuts, eggs, tree nuts and sesame, with possible soy traces. That matters if you manage allergies in addition to avoiding gluten.

Transparent Labs: a specific whey option, not a universal pick

Choose it if you want whey, like the idea of vanilla peanut butter and prefer stevia. The selected 2LB Vanilla Peanut Butter product is $64.99 for 30 labeled servings of 28g protein. The manufacturer nutrition image also lists 150 calories. Its currently accessible image gives a different scoop weight from our earlier label record; the protein and serving count used for the price calculation agree.

The formula combines whey isolate and peanut flour. That makes the buying decision quite clear: this is a candidate for someone who eats dairy and peanuts, not a substitute for a dairy-free or peanut-free powder.

Transparent Labs markets the selected product as gluten-free. Its Informed Choice and Informed Protein listings answer other testing questions; we have not established independent gluten-free certification for this exact variant. The label also carries a shared-equipment warning that includes wheat. A shared-equipment statement does not by itself overturn a gluten-free claim, but it is useful information to have before ordering.

We would shortlist this for its stated formula and flavor, not for an untested promise of easier digestion or faster recovery. If you already know you dislike stevia, there is little reason to start with a large tub of this flavor.

Optimum Nutrition: useful variety, with an exact-pack gap

Gold Standard 100% Whey is worth exploring when flavor choice is your main priority. Its U.S. page advertises 24g protein per serving and a gluten-free claim across the line information reviewed.

We would start with a smaller pack of an unfamiliar flavor. A bulk tub only becomes good value if you actually want to finish it.

We are not making a verified recommendation for Extreme Milk Chocolate in the 5 lb size yet. The selected storefront served a 2 lb nutrition image, so the full current 5 lb label, serving count and allergen panel have not been matched. That does not establish a problem with the powder; it limits the pack-specific information we can give you.

Whey or plant: make this decision first

If you avoid dairy, the plant options are the relevant starting point. If you eat dairy, whey belongs on the shortlist too. A gluten-free diet does not automatically require a dairy-free powder.

Whey is a milk protein. Lactose is milk sugar. Choosing a lower-lactose formula is a different decision from avoiding milk protein, and whey remains unsuitable for someone with a milk allergy. Our companion article, Is Whey Protein Gluten-Free?, explains those distinctions without making you decode a supplement label first.

A powder is most useful when it fills a practical gap: breakfast is short on protein, a meal is inconvenient after training, or you want a repeatable ingredient for a smoothie. If your meals already meet your needs, buying a powder is optional. The biggest scoop is not automatically the best purchase.

Research notes and sources

This is a research-based comparison, not hands-on taste, mixability, digestion or performance testing. Product links identify manufacturer pages or, for the ON price reference, the retailer iHerb. See our editorial methodology.

• Garden of Life: exact Vanilla item 658010116039; current label and manufacturer’s October 13 reply support the gluten-free wording used here. Its NSF contents listing is a separate record and is not being presented as a standalone gluten-free certificate. We have not received an all-lot exception statement.
• Vega: the reviewed current label is 829g/43.6g per serving/190 calories. NSF record 1708470 lists 828g and 1.86kg packs, a 41g serving, 170 calories and named lots. Exact current-tub coverage remains unconfirmed.
• Transparent Labs: selected variant 40007249428573 / SKU TPL005112 lists a base price of $64.99 and availability in the manufacturer product data. The current selected-page nutrition image lists 30 servings, 28g protein and 150 calories, but 38.4g per scoop versus 39.2g in our October 9 record. Scoop-weight discrepancy remains open; price calculations use the agreeing 30-serving/28g figures. Current nutrition image; the Informed Choice and Informed Protein records are not gluten-free certification.
• Optimum Nutrition: iHerb lists the exact 5 lb flavor at $114.99, with 71 servings, 32g per scoop and 24g protein. This supports a retailer-listed cost calculation, not confirmation that the manufacturer’s latest label or every shipping lot matches. The manufacturer page still supplies a 2 lb nutrition image. Its U.S. line gluten-free wording remains separate from retailer price evidence.
• Label evidence was reviewed October 6–13, 2026, with Garden of Life and Vega storefront prices rechecked October 24. We have not independently retested products or established new certification coverage today.
