The 6 Best Greek Yogurt Brands in 2026

#1 Best Protein Efficiency — FAGE Total 0% Plain

FAGE Total 0% Plain is the most protein-efficient mainstream Greek yogurt available: 18g of complete protein at just 90 calories per 170g (roughly 3/4-cup) serving. That 20g-of-protein-per-100-calories ratio — confirmed from FAGE’s own published label and verified across major retailer nutrition panels — leads every mainstream yogurt brand by a meaningful margin. The formula is straightforward: FAGE strains their yogurt more aggressively than most US brands, removing more whey and concentrating the milk proteins. The result is a very thick, dense product with only two ingredients: Grade A pasteurized skim milk and live active cultures. No thickeners, no added protein, no sweetener, no fruit, no pectin. The protein is entirely from naturally concentrated dairy — casein and whey in roughly a 4:1 ratio from the straining process. Stocked at Walmart, Target, Whole Foods, Kroger, and most major grocery chains in 5.3oz, 7oz, and 32oz containers. See the complete nutrition breakdown in our FAGE Total 0% nutrition guide.

The honest catch: FAGE Total 0% Plain is sold plain only — the standard 0% Total line is unflavored. If you need a pre-sweetened product, the FAGE split cups add fruit on the side, but the yogurt portion remains unsweetened. The 170g serving that delivers 18g of protein is slightly more than the 5.3oz (150g) single-serve cup size most other brands use — a 5.3oz cup of FAGE delivers roughly 16g of protein, not the full 18g. Measure by weight when protein precision matters.

#2 Best Everyday Pick — Chobani Non-Fat Plain

Chobani Non-Fat Plain is the most widely available mainstream Greek yogurt in the United States — stocked at Walmart, Target, Kroger, Safeway, Publix, Aldi, CVS, Walgreens, and thousands of convenience stores that carry no other Greek yogurt brand. At 15g of protein per 5.3oz cup for 90 calories (16.7g per 100 cal), the nutrition is excellent. The flavor is more neutral and slightly less tart than FAGE or siggi’s — which makes it the go-to for cooking and baking, where a strong tangy note can interfere with a sauce, marinade, or batter. A 32oz container runs around $3.50–$5.00 at major chains, making it one of the lowest cost-per-gram-of-protein dairy options at any grocery shelf. Chobani uses only Grade A milk and live cultures; no thickeners, no protein isolate powders, no added sweetener. Full nutrition breakdown in our Chobani Greek yogurt nutrition guide.

The honest catch: Chobani Non-Fat Plain is not the most protein-dense option in the category — FAGE Total 0% delivers 18g at 90 calories versus Chobani’s 15g at the same calories, a 20% difference that adds up if yogurt is a primary protein source. The milder sourness that makes it great for cooking can feel bland to people who want the pronounced tangy flavor of a more aggressively strained product. Chobani’s regular flavored cups use added sugar — anywhere from 11g to 19g per cup — which is a very different product from the plain nonfat discussed here. Read the label before buying.

#3 Best Clean Label — siggi’s 0% Plain Skyr

siggi’s 0% Plain is technically Icelandic skyr rather than Greek yogurt, strained more aggressively and with different bacterial cultures, producing a thicker, denser product. Nutritionally, the distinction matters mostly in one direction: skyr often reaches a higher protein density than Greek-style yogurts because of the more aggressive straining. siggi’s 0% Plain delivers 17g of protein per 5.3oz cup for 100 calories — 17g per 100 cal, ahead of Chobani (16.7g/100 cal) and approaching FAGE (20g/100 cal). The ingredient list for siggi’s 0% Plain is among the simplest in the category: skim milk, cream, and live active cultures. No thickeners, no pectin, no locust bean gum, no added sweetener, no added protein. The flavor is distinctly tangy — more so than Chobani, comparable to FAGE — with a pronounced dairy tartness that traditional fermented-dairy fans consider a sign of quality. Available at Whole Foods, Trader Joe’s, Target, and most natural-food retailers.

The honest catch: siggi’s 0% Plain runs $1.50–$2.00 per 5.3oz cup at retail — more expensive per ounce than FAGE or Chobani. The flavor is considerably more tart than most people expect from a store yogurt; if you are accustomed to sweetened yogurt, the plain skyr flavor is a significant adjustment that usually requires a taste test before committing to a multi-pack. Note that siggi’s FLAVORED cups use agave nectar — a real added sugar — and contain 9–12g of added sugar per cup. The plain 0% version has no added sugar; the flavored ones do. If your goal is zero added sugar in a flavored format, Oikos Triple Zero (stevia) is the better choice than siggi’s flavored cups.

#4 Best Flavored Zero-Added-Sugar — Oikos Triple Zero

Oikos Triple Zero is Danone’s answer for the consumer who wants a flavored yogurt — Vanilla, Strawberry, Mixed Berry, Blueberry, Peach, Banana Creme — without added sugar, artificial sweeteners, or fat. The “Triple Zero” name means: 0g added sugar, 0g fat, and 0 artificial sweeteners. The sweetness comes entirely from stevia leaf extract, a plant-derived non-caloric sweetener. At 15g of protein per 5.3oz cup for 90 calories (16.7g/100 cal), the protein efficiency nearly matches Chobani Non-Fat Plain despite being a pre-flavored product. The 5g of total sugar per cup is entirely naturally occurring — lactose from the dairy base plus a small contribution from the fruit components; none is added sugar. Widely stocked at Walmart, Target, Kroger, and most grocery chains. See the complete macro breakdown in our Oikos Triple Zero vs :ratio head-to-head.

The honest catch: stevia has a characteristic plant-derived sweetness that some people detect as a faintly bitter finish, especially at higher doses. Taste a single cup before buying a multi-pack if you’re new to stevia-sweetened products. For people who avoid all non-nutritive sweeteners — stevia included — Chobani Non-Fat Plain and FAGE Total 0% Plain are the right alternatives at comparable protein. Oikos Triple Zero comes only in single-serve 5.3oz flavored cups; there is no plain Oikos Triple Zero without sweetener.

#5 Best for Maximum Protein Per Cup — :ratio PROTEIN

:ratio PROTEIN delivers the most absolute protein of any mainstream yogurt cup: 25g per 5.3oz serving. No other flavored yogurt in a standard single-serve cup matches that number. The protein comes from ultra-filtered nonfat milk — a process that concentrates milk protein by removing lactose and water — combined with whey protein concentrate, producing 25g of complete dairy protein with all essential amino acids at 170 calories and only 3g of total sugar. :ratio is sweetened with sucralose and has 0g of added sugar. Currently owned by Lactalis USA after their June 2025 acquisition of General Mills’ US yogurt portfolio; the formula is unchanged. Note that :ratio PROTEIN is technically classified as a “cultured dairy snack” rather than yogurt under FDA definitions because of the ultra-filtration process — it eats like a Greek-style yogurt but cannot be labeled as one. Available in Vanilla, Strawberry, Blueberry, Mixed Berry, Coconut, and Key Lime at Walmart, Target, Kroger, and Whole Foods. Full data in our :ratio PROTEIN nutrition facts guide.

The honest catch: :ratio PROTEIN uses sucralose, a synthetic artificial sweetener; people who avoid synthetic sweeteners should choose Oikos Triple Zero (stevia) instead. At 14.7g of protein per 100 calories, :ratio is actually the least calorie-efficient pick on this list — it wins on absolute grams per cup, not protein efficiency. Two cups of Oikos Triple Zero deliver 30g of protein for 180 calories, beating one ratio cup (25g / 170 cal) on both total protein and efficiency. The single-container convenience of reaching 25g at once is :ratio’s real advantage for people tracking macros at a meal level.

#6 Best Low-Calorie Flavored Option — Two Good

Two Good is the lowest-calorie flavored Greek yogurt on this list: 12g of protein for just 80 calories per 5.3oz cup. The name refers to the 2g total sugar content — the lowest total sugar of any flavored product in this comparison. Danone achieves this through an extended slow-straining process that removes most of the lactose along with the whey, which is why total sugar is so low even without lactose-removal enzymes. The product is stevia-sweetened with 0g added sugar. At 15g of protein per 100 calories, the efficiency is solid but not the category leader. Two Good is the right pick for someone with a strict calorie ceiling who wants a flavored cup without added sugar, or for those with mild lactose sensitivity since the extended straining removes more lactose than standard Greek-style processing. Available in Vanilla, Strawberry, Blueberry, and Peach. See our Two Good vs Oikos Triple Zero comparison for a direct head-to-head.

The honest catch: at 12g of protein per cup, Two Good delivers noticeably less protein than Oikos Triple Zero (15g) at only 10 more calories. For most people, Oikos Triple Zero is the better nutritional choice unless the specific 80-calorie ceiling or the lower lactose content is the deciding factor. The 80-calorie count per cup is the lowest here, but the 10-calorie gap from Oikos Triple Zero (90 cal) rarely justifies the 3g protein sacrifice in a cup you’re eating specifically for protein.

What Makes Greek Yogurt Different from Regular Yogurt?

Greek yogurt is standard yogurt that has been strained through a fine cloth or filter to remove most of the liquid whey. This straining step concentrates the protein, removes lactose with the whey liquid, and creates the thick, dense texture distinctive of Greek-style products. A standard American yogurt typically has 5–8g of protein per 5.3oz serving; a well-strained Greek-style yogurt delivers 12–18g for the same volume. The removed lactose also makes Greek yogurt more digestible for people with mild lactose sensitivity compared to unstrained yogurt. Icelandic skyr (siggi’s) uses a similar but more aggressive straining process, often producing a denser product with comparable or higher protein density. On the calorie side, nonfat Greek yogurt and nonfat regular yogurt have similar calorie counts per serving because the fat that would have been removed with the whey is absent in both — the straining concentrates protein without meaningfully changing the calorie count of a nonfat base product.

Which Greek Yogurt is Best for Weight Loss?

For weight loss, the best Greek yogurt is the one with the most protein per calorie, because protein drives satiety without contributing large numbers of calories. By that metric, FAGE Total 0% Plain leads at 20g of protein per 100 calories and 0g added sugar with no sweetener. A 6oz serving as a snack provides a substantial protein hit at a calorie cost that most weight-loss calorie budgets can absorb. For a flavored option you can eat without adding sweetener yourself, Oikos Triple Zero is the best flavored weight-loss pick: 15g of protein for 90 calories, stevia sweetened, 0g added sugar. Both are significantly better than standard sweetened yogurt, which can contain 19–25g of added sugar per cup at 150–200 calories. See our high-protein snacks for weight loss guide for a broader food-category comparison.

How Much Protein Does Greek Yogurt Have?

The range across mainstream Greek yogurt brands is wider than most people expect: 12g to 25g of protein per 5.3oz single-serve cup. The median mainstream brand delivers around 14–18g per 5.3oz cup, depending on how aggressively it is strained and whether protein concentrate is added. At the high end, :ratio PROTEIN reaches 25g per cup through ultra-filtration and added whey protein. At the low end, lightly strained sweetened yogurts marketed as “Greek-style” can fall below 10g per cup. Plain nonfat versions consistently outperform flavored versions on protein per calorie because straining removes liquid and concentrates protein, while fruit and sweetener additions dilute the ratio. If protein efficiency is the goal, always buy plain nonfat and add your own fruit or a small amount of honey as needed — the protein advantage over a pre-flavored cup is real and consistent across all brands.

Frequently Asked Questions

Which brand of Greek yogurt has the most protein?

:ratio PROTEIN has the most absolute protein per cup at 25g per 5.3oz serving — the highest of any mainstream product we’ve verified. FAGE Total 0% Plain leads on protein efficiency at 20g per 100 calories, meaning it delivers more protein per calorie than any other mainstream brand. The right answer depends on whether you are optimizing for grams per cup or grams per calorie. For a full protein-density ranking, see our protein-ranked Greek yogurt comparison.

What is the difference between Greek yogurt and skyr?

Skyr is an Icelandic fermented dairy product made with different bacterial cultures than Greek yogurt and strained more aggressively, producing a thicker, denser result. Nutritionally, authentic skyr often achieves a slightly higher protein density per calorie than most US Greek-style yogurts — siggi’s 0% Plain Skyr delivers 17g of protein per 100 calories, on par with the best Greek yogurts. Flavor-wise, skyr is more tart and dense than typical US Greek yogurt. The FDA does not formally distinguish between Greek yogurt and skyr in labeling, so some US products use the terms interchangeably. Practically, choose between them based on protein data and ingredient labels rather than the terminology on the cup.

Can I use Greek yogurt instead of sour cream in cooking?

Yes. Plain nonfat Greek yogurt substitutes directly for sour cream in sauces, dips, dressings, and baked goods with significantly better nutrition: ~15g protein and 0g fat versus sour cream’s ~2g protein and 20g fat per 100g. The texture difference is minimal in cooked applications. The main caveat: Greek yogurt can curdle above roughly 175°F, so stir it in at the end of hot dishes rather than simmering it in a sauce. Chobani Non-Fat Plain and FAGE Total 0% Plain both work well because their flavor is mild enough not to overwhelm a dish.

Which Greek yogurt has no artificial sweeteners?

FAGE Total 0% Plain, Chobani Non-Fat Plain, and siggi’s 0% Plain Skyr contain zero sweeteners of any kind — no stevia, no sucralose, no aspartame. Oikos Triple Zero and Two Good use stevia leaf extract, which is plant-derived but still a non-nutritive sweetener. :ratio PROTEIN uses sucralose, a synthetic artificial sweetener. If avoiding all non-nutritive sweeteners is the goal, choose FAGE, Chobani Plain, or siggi’s Plain — all three are plain and unflavored; you add your own fruit or honey to sweeten.

Is Greek yogurt good after a workout?

Yes — Greek yogurt is one of the most effective real-food post-workout protein sources available. It delivers complete dairy protein with all essential amino acids including leucine, the amino acid most directly linked to muscle protein synthesis. The standard post-workout target is 20–40g of protein; a single cup of :ratio PROTEIN (25g) hits the lower end of that range alone. Pairing a FAGE Total 0% cup (18g) with a handful of nuts or a small protein shake covers the full target. The casein component of dairy protein also provides a slower-digesting protein fraction that supports muscle recovery over several hours — useful for long gaps between meals after training.

Bottom line: for the best protein-per-calorie ratio, FAGE Total 0% Plain is the clear leader at 20g per 100 calories — buy the 32oz container if you eat yogurt daily and are comfortable with plain, unsweetened yogurt. For a flavored cup with 0g added sugar, Oikos Triple Zero delivers 15g of protein at 90 calories with stevia and is widely stocked. For the most protein in a single container, :ratio PROTEIN at 25g is the only mainstream product that reaches that threshold per 5.3oz cup. For the simplest ingredient list with no sweetener, siggi’s 0% Plain is the clean-label specialty pick. For cooking versatility and everyday affordability, Chobani Non-Fat Plain is the practical default at most US grocery stores.
