Protein,
audited.

Ten expanded audits now separate formula, certification, company accountability, recognition and value. Every product image links to its audit; every full audit identifies the exact product and regional limits.

Still provisional. The table below is a live audit order, not a final “best protein” verdict. Products serve different buyers, formulas vary by flavour and country, and a higher score does not mean everyone should buy it.
Provisional audit order

Ten products. Six separate scores.

Awards, sales volume and affiliate economics are excluded. Value is shown separately because a technically strong product can still be a poor buy.

Klean Athlete Klean Isolate whey protein pouch#01 provisional
Whey isolate

Klean Isolate

A short, unflavoured isolate formula backed by a current NSF Certified for Sport listing. The technical trail is excellent; the value proposition is deliberately narrow and premium.

Dymatize ISO100 Gourmet Vanilla protein tub#02 provisional
Hydrolysed whey isolate

ISO100 Hydrolyzed

A lean whey-isolate formula with disclosed leucine and current region-specific Informed Choice batches. Technically strong, but hydrolysis does not guarantee a meaningful advantage for every buyer.

Myprotein Impact Whey Protein vanilla pouch#03 provisional
Whey concentrate

Impact Whey Protein

A high-volume, competitively priced whey concentrate with both Informed Choice and Informed Protein coverage. The key limitation is variation: nutrition, pack size and availability move materially by flavour and country.

Garden of Life SPORT Organic Plant-Based Protein vanilla tub#04 provisional
Plant protein blend

SPORT Organic Plant-Based Protein

A 30 g multi-source plant blend with an unusually dense certification stack. The outside evidence is strong; several added “recovery” ingredients are less decisive than the core protein dose.

Rule One R1 Protein Whey Isolate chocolate fudge tub#05 provisional
Whey isolate

R1 Protein Whey Isolate

A high-density isolate and hydrolysate formula with a current Informed Choice product entry. The public trail is good, though less lot detail was visible than for the category leaders.

Optimum Nutrition Gold Standard 100% Whey Double Rich Chocolate tub#06 provisional
Whey blend

Gold Standard 100% Whey

A globally available, isolate-led whey blend with strong label clarity and regional Informed Choice entries. Its biggest advantage is dependable availability—not a unique muscle-building effect.

Audit score86
Isopure zero carb whey protein isolate tub#07 provisional
Whey isolate

Zero Carb / Flavoured Protein

A lean 25 g isolate formula with zero-carb variants and added micronutrients. The major audit issue is certification geography: the current Informed Choice entry covers Asian Low Carb products, not automatically the U.S. Zero Carb tub.

Audit score79
MuscleTech Nitro-Tech milk chocolate protein tub#08 provisional
Whey + creatine blend

Nitro-Tech

A 30 g whey blend with 3 g creatine monohydrate. The formula is fully disclosed, but it is not a neutral protein-only comparison and the current public page does not identify a product-level external certification register.

Protein30 g
Audit score76
Orgain Organic Protein Creamy Chocolate Fudge tub#09 provisional
Plant protein blend

Organic Plant-Based Protein

A widely available organic plant blend with 21 g protein and useful fibre. Organic and plant-based certification support sourcing claims, but they are not substitutes for lot-level nutrient or contaminant results.

Protein21 g
Audit score76
GHOST Whey Milk Chocolate protein tub#10 provisional
Flavoured whey blend

GHOST Whey

A fully disclosed, flavour-led whey blend with 25 g protein. Transparency is better than the category stereotype; public product-level sport certification is the main missing piece.

Audit score67

Recognition is not evidence

Named awards show who issued them, the year and the judging context. They are excluded from the product score.

Testing is region-specific

A certification for Asia, Europe or the United States is never transferred to another formula without a matching directory entry.

Commercial wall

No active retailer or affiliate link appears in these audits. Future monetised links will be labelled and will not alter ranking or score.
