Best High-Protein Greek Yogurts
Greek yogurt is one of the highest-protein whole foods on the US grocery shelf. We graded every Greek yogurt in our database against the v3 Labelgrade methodology, then ranked them by protein content per serving. Includes plain and lightly-sweetened varieties — for everything else, see the full /explore page.

How we picked these
Every product in this roundup is a strained Greek-style or skyr yogurt with ≥10 g of protein per serving — the FDA "high in protein" threshold. We sort first by absolute protein content per labeled serving (the spec most readers actually want), with Labelgrade overall as a tiebreaker when products are within 2 g. The "Why we picked these" filter excludes flavored fruit-on-the-bottom varieties where added sugar pushes the product past 12 g per serving.

Frequently Asked Questions
Which Greek yogurt brand has the most protein?
Among unsupplemented Greek yogurts (plain, no added whey protein), Fage Total 0% leads the US market at about 18 g of protein per 100 g (~24 g per 5.3 oz cup). Among supplemented Greek yogurts (with added whey protein concentrate or isolate), Oikos Pro and Triple Zero both reach 20+ g per 100 g — but at the cost of an ingredient list that's no longer just milk + cultures.
Are flavored Greek yogurts still high-protein?
Yes, but with sugar trade-offs. Most flavored Greek yogurts retain 12–17 g of protein per cup, but add 10–15 g of sugar from fruit + cane sugar. The non-fat plain versions are the cleanest base; flavored varieties move from a protein source toward a dessert source as sugar climbs. The middle ground is "lightly sweetened" varieties (Two Good, Yoplait Greek 100) that use stevia or monk fruit instead of cane sugar — protein-dense without the sugar cost.
Why is the protein content different between "Greek" yogurts at the same fat level?
Three reasons. (1) Straining intensity — more thorough straining concentrates more protein. Fage strains more aggressively than most. (2) Added whey protein — brands like Oikos Pro, Triple Zero, and Yoplait Greek 100 spike their formulas with extra whey concentrate to hit a "20 g per serving" marketing target. (3) Serving size variation — most 5.3 oz cups are 150 g, but some brands use 170 g, which inflates the labeled per-serving number even at lower density.
Is added whey protein a downside?
Depends what you value. Pro: more protein per serving. Con: longer ingredient list, sometimes including milk protein concentrate, whey protein concentrate, stevia, lactase enzyme. Fage Total 0% has 2 ingredients (cultured pasteurized skim milk + 5 live cultures). Oikos Pro Vanilla has 9 ingredients including supplemented protein. For pure ingredient quality, unsupplemented wins. For total protein per cup, supplemented wins. Both are legitimate choices.
How does the sugar compare to regular yogurt?
Plain Greek yogurt has less sugar than plain regular yogurt — the straining removes lactose with the whey. Plain non-fat Greek yogurt: 3.6–4 g of sugar per 100 g. Plain non-fat regular yogurt: 6–8 g per 100 g. Flavored Greek yogurts close this gap quickly — a "blueberry" Greek yogurt with added sugar can hit 10–14 g per 100 g.
Best plain non-fat option?
Fage Total 0% Plain is the protein-density leader and the cleanest ingredient list (cultured pasteurized skim milk + 5 live cultures). Chobani Plain Non-Fat is a close second at slightly lower protein density. Both score A or A− on our v3 methodology.
Best protein-supplemented option?
Oikos Pro Vanilla is the highest-protein US Greek yogurt at ~20 g per 150 g cup. Triple Zero (Dannon Oikos) is close, with 15 g protein + 0 added sugar + 0 fat. Both use added whey protein to clear the 20 g bar. They're engineered products, not minimalist — but they hit a specific use case (post-workout cup, max protein per oz) better than unsupplemented options.
Are Icelandic skyr products the same as Greek yogurt?
Mechanically similar — both are strained dairy. Skyr is technically classified as a fresh cheese in Iceland, but in the US market it's sold and regulated as yogurt. Siggi's is the dominant skyr brand. Protein density runs 13–18 g per 100 g — slightly less than Fage but cleaner-tasting and often lower in sugar than flavored Greek yogurts.
