Oikos Triple Zero Nutrition: 15g Protein, 0g Added Sugar, 90 Calories per Cup

A single 5.3oz (150g) cup of Oikos Triple Zero Greek nonfat yogurt has about 90 calories, 15g of protein, 5g of total sugar, 0g of added sugar, 6g of total carbs, and 0g of fat. That holds true across nearly every flavor in the lineup. Oikos Triple Zero is made by Danone (the same company behind Two Good, Light & Fit, and the rest of the Oikos range), and the "Triple Zero" name refers to its three headline claims: 0 added sugar, 0 artificial sweeteners, and 0% fat. The 15g of protein per cup is the other big selling point. Below are the verified per-cup numbers flavor by flavor, what "triple zero" actually means, how it compares to other high-protein yogurts, and whether it is a smart pick.

Oikos Triple Zero Nutrition Facts (Per 5.3oz Cup)

Every single-serve Oikos Triple Zero cup uses a 5.3oz (150g) serving and delivers 15g of protein with 0g of added sugar, 0% fat, and no artificial sweeteners. The small amount of total sugar you see (around 5g) comes from naturally occurring milk sugar (lactose) and fruit, not from added sugar. Here are the verified per-cup numbers for the core flavors.

The numbers are nearly identical across the lineup because every flavor is built on the same nonfat Greek yogurt base, sweetened with stevia leaf extract and flavored with natural flavors and fruit or vegetable juice concentrates rather than fruit-on-the-bottom sugar. Other blended flavors such as Banana Crème, Cherry, and Peach carry the same headline 15g protein, 0g added sugar, and 0g fat per cup. Vanilla runs a touch higher on carbs (about 7g) on some panels, and you may occasionally see a cup listed at 80 to 100 calories depending on the print run and the database, but 90 calories with 15g protein and 0g added sugar is the consistent headline. The 32oz quart tubs (Vanilla and Plain) list nutrition against a larger 3/4 cup (170g) serving, so those numbers will read higher per serving simply because the portion is bigger.

What Does "Triple Zero" Mean?

The "Triple Zero" name is a marketing claim about three specific zeros, and it is worth knowing exactly what each one does and does not mean:

• 0g added sugar: No cane sugar, corn syrup, or other sweeteners are added. The ~5g of total sugar per cup is naturally occurring lactose and fruit sugar. It is not a zero-sugar product.
• 0 artificial sweeteners: Instead of sucralose or aspartame, Oikos Triple Zero is sweetened with stevia leaf extract, a plant-derived non-nutritive sweetener.
• 0% fat: It is made from cultured nonfat (skim) milk, so each cup has 0g of fat.

Notably, the "triple zero" claim says nothing about calories. Oikos itself notes the product is not a low-calorie food, though at roughly 90 calories per cup it is still light. The headline you should care about for a protein snack is the 15g of protein for those 90 calories, which is a strong protein-to-calorie ratio.

Is Oikos Triple Zero Actually Healthy? Who It's For

For most goals, yes. You get 15g of complete dairy protein for about 90 calories with no added sugar and no fat, which is an excellent macro profile for a grab-and-go snack. It fits well for weight loss, blood-sugar-conscious eaters, post-workout recovery, and anyone trying to hit a daily protein target without extra sugar. If you like under-100-calorie snacks, it belongs alongside our best protein snacks under 100 calories.

The main trade-off is the stevia. Because there is no added sugar, the sweetness comes entirely from stevia leaf extract, so if you dislike the aftertaste of stevia or prefer to avoid non-nutritive sweeteners, that is the thing to know going in. It is also worth remembering that "0 added sugar" still leaves about 5g of naturally occurring sugar per cup, so it is low-sugar rather than sugar-free.

Oikos Triple Zero vs Other High-Protein Yogurts

Here is how Oikos Triple Zero stacks up against the other popular high-protein, low-sugar yogurts. Serving sizes differ slightly between brands, so they are noted in the table.

Oikos Triple Zero lands in a sweet spot: more protein than Two Good (15g vs 12g) and Chobani Zero Sugar (15g vs 11g), with no added sugar and no fat. Fage Total 0% edges it on protein (18g) but is unsweetened and plain. siggi's has the most flavor sweetness but also the most sugar. Chobani Zero Sugar is the only truly 0g-sugar cup but is lowest in both calories and protein.

Frequently Asked Questions

How much protein is in Oikos Triple Zero?

Each 5.3oz single-serve cup has 15g of protein. That is more than Two Good (12g) and Chobani Zero Sugar (11g) per cup, and only a few grams behind plain Fage Total 0% (18g). It makes Oikos Triple Zero one of the higher-protein flavored Greek yogurt cups on shelves.

Is Oikos Triple Zero sugar-free?

No. It has 0g of added sugar, but about 5g of total sugar per cup that comes naturally from milk (lactose) and fruit. So it is low-sugar, not sugar-free. If you need a 0g-sugar option, Chobani Zero Sugar is the closest comparison.

What sweetener does Oikos Triple Zero use?

It is sweetened with stevia leaf extract, a plant-derived non-nutritive sweetener, which is what lets it claim "0 added sugar" and "0 artificial sweeteners" at the same time. There is no sucralose or aspartame in the standard cups.

Is Oikos Triple Zero keto-friendly?

It can fit a low-carb or keto budget. Each cup has only about 6 to 7g of total carbs and 0g of fat, so it slots into most carb allowances easily, though the protein-heavy, near-zero-fat profile means it is not a classic high-fat keto food. Count it within your daily totals.

Bottom line: Oikos Triple Zero is a 15g-protein, 0g-added-sugar, fat-free Greek yogurt at roughly 90 calories per cup, sweetened with stevia. It is one of the better protein-per-cup flavored yogurts if you are fine with stevia. If you want fewer calories or even less sugar, compare it with Two Good and the rest of the field in our Greek yogurt rankings, or browse the full protein snacks directory to find your next staple.
