Oikos vs FAGE (2026): Which Greek Yogurt Wins on Protein, Sugar, Stevia, and Ingredients

Oikos and FAGE are the two Greek yogurts most American shoppers actually choose between, and they get to a high protein number in completely different ways. FAGE Total is the traditional approach: milk, cultures, then straining until a 5.3 oz cup holds 16g of protein. Oikos is the engineered approach: Triple Zero is a “blended” nonfat Greek yogurt with tapioca starch and stevia, and Oikos Pro starts from ultra-filtered milk and adds whey protein concentrate to reach 20g per cup. Neither is wrong. They are built for different buyers, and once you see the two nutrition panels side by side the choice takes about a minute.

The Quick Verdict: Oikos vs FAGE Head-to-Head

Single cups first, because that is what most people buy. FAGE Total 0% Plain, Oikos Triple Zero Vanilla, and Oikos Pro Vanilla are all sold as 5.3 oz (150g) cups, so this is an even comparison.

Read across that table and the pattern is clear. Oikos Pro has the most protein and the most calcium, and it also has the longest ingredient list, the most fat and cholesterol, and the lowest protein-per-calorie ratio of the three. FAGE Total 0% has the shortest list, the most cultures, and the leanest protein. Triple Zero splits the difference: as light as FAGE at 80 calories, but flavored and stevia-sweetened.

Which Has More Protein: Oikos or FAGE?

Per cup, Oikos: Oikos Pro Vanilla carries 20g of protein in a 5.3 oz cup against 16g in FAGE Total 0% and 15g in Oikos Triple Zero Vanilla. Per calorie, FAGE: 20g of protein per 100 calories versus 18.8g for Triple Zero Vanilla and 15.4g for Oikos Pro. Per 170g tub serving the gap widens at the top, because Oikos Pro Plain lists 25g of protein for 160 calories while FAGE Total 0% lists 18g for 90 calories and Oikos Triple Zero Plain lists 18g for 100 calories. So the answer depends on what you are optimizing: the biggest protein number in one cup is Oikos Pro, and the most protein for the fewest calories is FAGE Total 0%.

FAGE Total 0%: The Cleanest Label and the Leanest Protein

The FAGE Total 0% ingredient list is two lines long: Grade A pasteurized skimmed milk, and live active yogurt cultures (L. bulgaricus, S. thermophilus, L. acidophilus, Bifidus, L. casei). There is no starch, no flavoring, no sweetener, no added vitamin, and no preservative. Everything on the panel comes from milk that has been cultured and strained. The 5.3 oz cup lists 80 calories, 16g of protein, 5g of naturally occurring milk sugar, 0g added sugar, 10mg of cholesterol, 55mg of sodium and 180mg of calcium. The 170g serving from the tub lists 90 calories and 18g of protein. At 20g of protein per 100 calories it is the most efficient protein source in this comparison by a comfortable margin.

Five named live cultures is also more than any Oikos cup, which lists two. Neither brand publishes a colony count, so “five versus two” is a count of strains, not a measure of how many live bacteria reach you. It is still the more diverse culture blend, and it is the one that comes with nothing else in the cup.

The honest catch: FAGE Total 0% is unflavored and, like any plain strained yogurt, tart. FAGE’s flavored answer is the Total Split Cup, which pairs the same plain yogurt with a separate fruit or honey compartment rather than a sweetened, vanilla-flavored yogurt like Triple Zero. If you are coming from a sweet vanilla Oikos, you will be adding fruit or honey yourself, and every gram of that is sugar you chose rather than sugar on the label. FAGE also lists 0mcg of vitamin D, where both Oikos cups are fortified to 10% of the daily value. Full panel: FAGE Total 0% nutrition facts.

FAGE Total 2% and 5%: Same Two Ingredients, More Fat, Less Protein

The 2% and 5% versions add cream to the same skimmed milk and the same five cultures, and that is the only change to the ingredient list. What changes on the panel is the fat and, less obviously, the protein. FAGE Total 2% lists 100 calories, 15g of protein and 3g of fat per 5.3 oz cup (120 calories and 17g of protein per 170g). FAGE Total 5% lists 140 calories, 14g of protein and 8g of fat per cup, of which 5g is saturated, which is 27% of the daily value in one small cup (160 calories and 15g of protein per 170g). Sugar stays at 5g in every version, all of it lactose.

The honest catch: the protein-per-calorie ratio falls fast as the fat goes up. FAGE 0% gives you 20g of protein per 100 calories, 2% gives you 15g, and 5% gives you 10g, which is the lowest ratio of any product on this page, below even Oikos Pro. If you are buying FAGE for the protein, buy the 0% or the 2%. If you are buying the 5% you are buying it for the richness and the fullness that fat brings, which is a legitimate reason, just a different one.

Oikos Triple Zero: The Lightest Flavored Cup

Triple Zero is the Oikos cup built to compete with FAGE 0% on calories while tasting like dessert. The Vanilla cup lists 80 calories, 15g of protein, 0g fat, 6g of carbohydrate, 5g of total sugars and 0g added sugar, with 150mg of calcium and 2mcg of vitamin D. The “triple zero” on the front means 0g added sugar, 0g fat and 0 artificial sweeteners, and the label holds to that: the sweetness comes from stevia leaf extract, which is plant-derived rather than artificial. The ingredient list is cultured Grade A nonfat milk, water, and less than 1% of natural flavors, tapioca starch, stevia leaf extract, lemon juice concentrate, sea salt and vitamin D3, plus two yogurt cultures.

The Plain version, sold in a quart, is a different product on paper. Per 170g it lists 100 calories, 18g of protein, 7g of sugar and 0g added sugar, and its ingredient list is simply cultured nonfat milk and two cultures, with no stevia, no starch and no flavoring. It is the closest thing Oikos makes to FAGE Total 0%, and it comes in 2g of protein and 10 calories behind per 170g.

The honest catch: Triple Zero Vanilla is a “blended” Greek yogurt with tapioca starch on the label, not a plain strained yogurt, and stevia is a taste some people never get used to. It lists two cultures to FAGE’s five and the least calcium of any cup here at 10% of the daily value. One more thing to know: the panel Oikos publishes today lists 0g of dietary fiber and no chicory root, while our own product database still holds an older Triple Zero Vanilla record showing 6g of fiber. Go by the current label; the fiber is not there anymore. Full panel: Oikos Triple Zero nutrition facts.

Oikos Pro: The Highest-Protein Cup

Oikos Pro is where Oikos beats FAGE on the number most people look at first. The Vanilla cup lists 130 calories, 20g of protein, 3g of fat (2.5g saturated), 25mg of cholesterol, 45mg of sodium, 6g of carbohydrate, 3g of total sugars and 0g added sugar, plus 220mg of calcium, 2mcg of vitamin D, and B vitamins at 20% of the daily value for riboflavin and B6 and 50% for B12. The Plain quart goes further: per 170g it lists 160 calories, 25g of protein, 4g of sugar and 270mg of calcium, 20% of the daily value, which is the highest calcium figure in this comparison.

It gets there differently from FAGE. The first ingredient is cultured Grade A ultra-filtered nonfat milk, then water, whey protein concentrate and cream, then less than 1% of tapioca starch, natural flavors, lemon juice concentrate, stevia extract, potassium sorbate to maintain freshness, vitamin D3, vitamin B6, riboflavin and two yogurt cultures. Oikos itself labels Pro a “cultured ultra-filtered milk” product rather than a strained Greek yogurt. Full panel: Oikos Pro nutrition facts.

The honest catch: Oikos Pro is a protein-fortified yogurt, and the fortification shows up on the panel. Its 15.4g of protein per 100 calories is the lowest ratio of the nonfat and lowfat cups here, its cholesterol is two and a half times FAGE 0%, and the flavored cup carries a preservative (potassium sorbate) and a sweetener (stevia) that neither FAGE Total nor the Oikos Pro Plain quart has. If your goal is the biggest protein number per cup with 0g added sugar, nothing in this comparison touches it. If your goal is the shortest label, it is the longest one here.

Full Lineup Comparison

Every product in both lines that we compared, on the serving size each brand prints. Single cups are 150g; tub and quart servings are 170g (3/4 cup). Protein per 100 calories is our arithmetic from the label figures.

Every product in both lines lists 0g added sugar; the sugar column above is naturally occurring milk sugar in every case. Sodium runs from 45mg (Oikos Pro Vanilla) to 65mg (FAGE 0% tub) across the board, which is low enough that it should not decide anything.

Does Oikos or FAGE Have Stevia or Artificial Sweeteners?

Neither brand uses an artificial sweetener, but every flavored Oikos cup is sweetened with stevia, and no FAGE Total product is sweetened with anything. Oikos Triple Zero Vanilla lists stevia leaf extract and Oikos Pro Vanilla lists stevia extract; neither lists sucralose, acesulfame potassium or aspartame, which is what the “0 artificial sweeteners” claim on the Triple Zero lid refers to. FAGE Total 0%, 2% and 5% plain list no sweetener, no flavoring and no starch, so their 5g of sugar is lactose and nothing else. If you want zero sweetener of any kind and still want Oikos, the Triple Zero Plain and Oikos Pro Plain quarts are unsweetened; in a single cup, the unsweetened option is FAGE.

Is Oikos or FAGE Healthier?

For the shortest ingredient list, the most live cultures and the most protein per calorie, FAGE Total 0% is the healthier cup; for the most protein, the most calcium and added vitamin D and B12 in one serving, Oikos Pro is. The panels do not disagree with each other, they just answer different questions. Two figures worth noticing before you decide: FAGE Total 5% carries 5g of saturated fat per cup, 27% of the daily value, which is by far the most of anything here, and Oikos Pro carries 25mg to 30mg of cholesterol against 10mg in FAGE 0% and Triple Zero. If your doctor has you watching saturated fat, FAGE 0% or 2% is the FAGE to buy, and if you are watching cholesterol, Triple Zero or FAGE 0% beats Oikos Pro.

Which Is Thicker, Oikos or FAGE?

A nutrition label cannot measure thickness, but it does show how each brand gets there. FAGE Total lists milk and cultures only, so its body comes entirely from straining the whey out, which is also why a 150g cup concentrates to 16g of protein with nothing added. Oikos Triple Zero is labeled a “blended” Greek yogurt and lists tapioca starch, a thickener. Oikos Pro lists whey protein concentrate and cream, which add body and protein without straining. If you want the dense, spoon-stands-up texture of a traditional strained yogurt, the ingredient lists point to FAGE. If you prefer something smoother and more spoonable, the Oikos lists point that way.

How we compared

We read the Nutrition Facts panel and the ingredient statement for each product from the brand’s own product pages on September 9, 2026: usa.fage for FAGE Total 0%, 2% and 5%, and oikos.com for Oikos Triple Zero Vanilla, Triple Zero Plain, Oikos Pro Vanilla and Oikos Pro Plain. Single cups were compared per 150g cup and tubs and quarts per 170g serving, exactly as printed. Protein per 100 calories is our division of the label’s protein by the label’s calories. We did not use retailer summaries or third-party nutrition databases for any figure, and where our own catalog disagreed with a current panel (the Triple Zero fiber figure) we went with the panel and said so. Prices move weekly and vary by store, so we do not print them; the buttons above go to the current Amazon listing. Both brands note that formulations can change, so check the cup in your hand if a number matters to you.
