Fage vs Chobani vs Oikos Pro: Greek Yogurt Compared
Three of the highest-protein-density packaged dairy products on the US market, side-by-side. Oikos Pro wins on per-cup protein delivery (boosted by added whey concentrate). Fage wins on density without additives. Chobani is the value play that still beats most everything else on the shelf.
The short answer
Oikos Pro Vanilla delivers the highest protein density (13.3 g per 100 g) and the most per-cup protein (20 g in a single-serve cup), thanks to added whey protein concentrate. Fage Total 0% is the densest clean-ingredient option (10 g per 100 g, 18 g per cup) with only milk plus live cultures. Chobani Plain Non-Fat is the value play (8.9 g per 100 g, 16 g per cup) with the same ultra-short ingredient list as Fage. All three score in a tight B+ band on the v3 Labelgrade scale.

- Densest without added protein. 10 g per 100 g from straining alone — no whey concentrate, just milk.
- No artificial or non-nutritive sweeteners. You control sweetness by what you add yourself.
Where Chobani wins
- Typically the lowest price per ounce. Most affordable of the three at retail.
- Cleanest ingredients (tied with Fage). Cultured nonfat milk plus six live and active cultures.

Who should buy which
Buy Oikos Pro if you're hitting a daily protein target, want the most protein per spoonful, and don't mind a longer ingredient list including added sugar and stevia. Best for busy macro-tracking or as a meal-replacement-adjacent food.
Buy Fage Total 0% if ingredient simplicity matters and you'll pay a small premium for it. Best for pure whole-food protein with no sweeteners you didn't add yourself, or for using yogurt as a culinary ingredient.
Buy Chobani Plain Non-Fat if you want the cleanest ingredient profile at the lowest cost. Best for daily volume consumption — large tub purchases for meal prep or family use.
How they were graded
All three products use the v3 6-dimension Labelgrade formula (see /methodology): protein density 23% + ingredient quality 21% + saturated fat 18% + sodium 15% + sugar 15% + fiber 8%. Data from USDA: Fage (FDC 2756888), Chobani (FDC 2755837), Oikos Pro (FDC 2755594).
Frequently Asked Questions
Which Greek yogurt has the most protein — Fage, Chobani, or Oikos Pro?
Per 100g: Oikos Pro is densest at 13.3g (boosted by added whey protein concentrate). Fage Total 0% is 10g (achieved through straining alone, no added protein). Chobani Plain Non-Fat is 8.9g. Per cup: Oikos Pro delivers 20g, Fage 18g, Chobani 16g.
Which has the cleanest ingredients?
Fage and Chobani are tied for cleanest — both list only milk plus live cultures. Fage uses Grade A pasteurized skimmed milk + 5 cultures; Chobani uses cultured nonfat milk + 6 cultures. No thickeners, no added sugar, no sweeteners in either. Oikos Pro is more complex: it adds whey protein concentrate, tapioca starch, sugar, stevia, natural flavors, and potassium sorbate.
Does any of them have added sugar?
Fage Plain and Chobani Plain Non-Fat have zero added sugar — the sugars listed are all naturally-occurring lactose. Oikos Pro Vanilla contains some added sugar plus stevia leaf Reb M, but the total sugars per serving (7g per 240g) are still low.
Which is best for muscle building?
Oikos Pro wins on per-cup protein delivery (around 20g per single-serve cup). Fage Total 0% is the strongest "clean whole-food" option (17g per cup). If you're hitting a daily protein target and want max protein per spoonful, Oikos Pro. If you want the cleanest profile and don't mind one extra cup, Fage delivers similar daily totals.
How do the new Labelgrade scores compare?
After the 2026-05-27 v3 scoring update (which added saturated fat as a dimension and tightened the sodium scale), all three nonfat strained yogurts score in a tight band. Plain Fage and Chobani score very close because they're structurally similar (just milk + cultures, both nonfat). Oikos Pro is slightly behind on ingredient quality but ahead on per-cup protein density.
Which is best value per gram of protein?
Chobani Plain Non-Fat is typically priced lowest per ounce. Fage Total 0% is mid-range. Oikos Pro tends to be priced 30-60% above plain strained yogurts. On a per-gram-protein basis, Chobani usually wins on value.
