Labelgrade

Best Low-Sugar Yogurts

Yogurt has a sugar problem hiding in plain sight: most of the sweetness on the shelf is added, and the labels don't always say so. We graded every yogurt in our database against the v3 Labelgrade methodology, then ranked them by the spec that matters here — lowest total sugar per serving (ties broken by overall grade). For the protein-first version of this list, see best high-protein Greek yogurts; for everything else, the full /explore page.

Short answer

The lowest-sugar pick in our data is Chobani Zero Sugar Vanilla Greek Yogurt at 0 g of sugar per serving. But the more useful answer is a category, not a single cup: plain strained Greek yogurt and the genuine zero-sugar lines are the low-sugar tier, and they win for the same reason — they don't add sugar in the first place. Straining removes natural lactose with the whey, and the zero-sugar cups replace sweetness with allulose, stevia, or monk fruit.

Two honest notes before the list. First, flavored almost always means sweetened: a "blueberry" or "vanilla" cup typically carries 12-18 g of total sugar versus ~4 g of plain lactose, so the flavor is the sugar. Second, USDA Branded Foods often hides added sugar — the added-sugar line is frequently left blank even when cane sugar is right there in the ingredients, which makes some products look cleaner than they are. We unpack that data gap in our report on hidden added sugar in protein foods.

The ranked list

Ranked by lowest total sugar per serving. "Sugar grade" is the Labelgrade v3 sugar-load dimension; "overall" is the composite grade. Serving sizes differ by product (most retail cups are 5.3 oz / 150 g; some USDA references are 180-240 g) — see each fact sheet for the exact basis. All values live from our graded catalog.

Plain wins — and it isn't close

If sugar is your one concern, stop reading and buy plain. A plain non-fat Greek yogurt — Fage Total 0%, Chobani Plain Non-Fat, or Oikos Plain — has zero added sugar and a one- or two-line ingredient list (cultured milk plus live cultures). The sugar it does show is naturally-occurring lactose, and straining removes a good chunk of even that along with the whey. These cups score A+ on the sugar dimension and land in A- to B+ territory overall, held back only by the zero fiber every dairy product carries. The trade is that you sweeten it yourself; a handful of fresh berries adds a few grams of real sugar and keeps you far below any flavored cup.

The catch worth naming: a bigger USDA reference serving makes the lactose number look higher than a retail cup. Fage's 9 g and Chobani Plain's 10.8 g in the table are measured on the 180 g USDA serving — the same yogurts run closer to 4 g of lactose in a standard 5.3 oz cup, and none of it is added. Read the sugar grade, not just the raw gram count, when the serving basis differs.

The zero-sugar and stevia cups: how they pull it off

The genuinely engineered low-sugar yogurts split into two sweetener camps, and the camp matters more than the headline number. The cleaner approach is Chobani Zero Sugar: ultra-filtration strips most of the lactose, then allulose, stevia leaf extract, and monk fruit do the sweetening — no sucralose, no acesulfame K, no aspartame. It legitimately reads 0 g of sugar at about 70 calories per cup with ~19.5 g of protein. Oikos Triple Zero and Two Good sit nearby, sweetening with stevia and showing only residual lactose (0 g added sugar for Triple Zero, ~3-4 g total for Two Good).

The other camp hits a low number with artificial high-intensity sweeteners. Yoplait Greek 100 and Dannon Light + Fit keep added sugar to ~2-3 g — but they get there with sucralose and acesulfame potassium, not by leaving the cup lightly sweetened. The macros are real and the sugar truly is low; whether that's the right cup comes down to how you feel about artificial sweeteners. Our position is neutral on the safety debate and specific on the disclosure: every product page names the exact sweetener system so you can decide. If you want low sugar and no artificial sweeteners, the allulose/stevia cups are your tier.

If you want flavor: the least-bad sweetened cups

Sometimes you want a ready-to-eat fruit yogurt, not a plain cup you have to dress. Among the cups that use real cane sugar, Siggi's is the standout: its peach skyr carries about 5 g of added sugar — built on a "not a lot of sugar" brand philosophy — versus the 12-15 g of added sugar in mainstream fruit-on-the-bottom yogurts, and it uses no artificial sweeteners at all. That's the honest middle ground: a little real sugar, a short ingredient list, a tarter taste.

Below that line, the math gets worse fast. A standard flavored Greek cup like Activia Peach reaches ~14 g of sugar with cane sugar as a top ingredient, and the non-Greek "Original" fruit yogurts climb to 15-18 g while delivering a fraction of the protein — at that point you're eating a dessert with a yogurt label. The reliable rule: if the cup is flavored and doesn't name stevia, monk fruit, or allulose, assume the sweetness is mostly added cane sugar, and check the panel against our hidden added-sugar report before you trust a blank added-sugar line.

How we picked these

Every product here is a yogurt or strained skyr in our graded database with a reported total-sugar value. We rank by total sugar per serving ascending — the spec the low-sugar shopper actually wants — and break ties on the Labelgrade overall score. The filter also pulls in strained Greek yogurts that USDA files under "Milk/Milk Substitutes" (Fage, Chobani, Two Good) so the genuine low-sugar leaders aren't dropped on a category technicality; plain drinking milk and plant milks are excluded. Serving sizes are not uniform, so read the sugar grade alongside the raw grams.

All nutrition data comes from USDA FoodData Central, with the documented caveat that the added-sugar line is often missing — the basis for our companion hidden added-sugar report. Grades follow the v3 Labelgrade methodology. Last refreshed 2026-05-29.

Frequently Asked Questions

Which yogurt has the least sugar?

On a strict total-sugar basis, the lowest-sugar cup in our database is Chobani Zero Sugar Vanilla Greek Yogurt at 0 g of sugar per serving. The reason it can read that low is a two-step trick: ultra-filtration strips most of the natural lactose, then the sweetness comes from allulose, stevia, and monk fruit rather than added sugar — so the label legitimately shows near-zero sugar. Plain strained Greek yogurts (Fage Total 0%, Chobani Plain, Oikos Plain) carry slightly more because they keep all of their natural lactose, but none of that is added sugar either.

Is plain yogurt really lower in sugar than flavored?

Almost always, yes — and the gap is large. Plain strained Greek yogurt has only naturally-occurring lactose (roughly 4 g per 5.3 oz cup, more on a bigger USDA serving), and the straining process actually removes lactose with the whey. A flavored fruit yogurt adds cane sugar and fruit-juice concentrate on top of the lactose, typically pushing total sugar to 12-18 g per cup. "Flavored" is a near-synonym for "sweetened" in the dairy aisle. The cleanest low-sugar move is plain yogurt plus your own fruit.

Does "no added sugar" mean low sugar?

Not by itself. "No added sugar" only means no caloric sweetener was added — the cup can still carry natural lactose (and fruit sugar in flavored versions). Oikos Triple Zero and Two Good show 0 g added sugar but still list 3-6 g of total (lactose) sugar. Separately, watch the reverse problem: USDA Branded Foods frequently omits the added-sugar line entirely, so a product can name cane sugar in its ingredients while showing a blank added-sugar field. We dig into that data gap in our hidden added-sugar report.

How do zero-sugar yogurts hit 0 g of sugar?

Two ways, and the distinction matters. The cleaner route (Chobani Zero Sugar) is ultra-filtration to remove lactose, then allulose + stevia + monk fruit for sweetness — no artificial sweeteners. The other route (Yoplait Greek 100, Dannon Light + Fit) keeps the sugar low using sucralose and acesulfame potassium, two artificial high-intensity sweeteners. Both legitimately produce a low number on the label; whether you prefer allulose/stevia or sucralose/ace-K is the real choice. We flag the sweetener system on every product page.

Which flavored yogurt has the least sugar?

If you want a ready-to-eat flavored cup, the least-bad options sweeten with stevia or monk fruit rather than a full dose of cane sugar: Oikos Triple Zero (stevia, 0 g added), Two Good (stevia, ~3-4 g sugar), and Chobani Zero Sugar (allulose/stevia/monk fruit, 0 g). For a flavored cup that uses only real cane sugar — no artificial sweeteners — Siggi's runs about 5 g of added sugar, well under the 12-15 g in mainstream fruit yogurts. Avoid the "fruit on the bottom" and Original (non-Greek) lines if sugar is the priority.
