:ratio PROTEIN Yogurt Nutrition Facts (2026): 25g Protein, 170 Calories, Zero Added Sugar — All Flavors Verified

:ratio PROTEIN Yogurt Nutrition Facts (5.3 oz Cup)

The numbers below are per container — a single 5.3 oz (150g) cup — sourced from the brand’s own official label and cross-checked against major retailer listings. All five current flavors (Vanilla, Strawberry, Blueberry, Key Lime, Mixed Berry) carry the same macro profile; the label does not break out fiber separately, indicating a value below the 1g threshold for mandatory disclosure.

Ingredients (Vanilla): Cultured Pasteurized Ultra-Filtered Nonfat Milk, Cultured Pasteurized Milk, Whey Protein Concentrate, Nonfat Milk, contains 2% or less of: Sunflower Oil, Sucralose, Natural Flavor, Carrageenan. Contains: Milk.

The 3g of total sugar is entirely naturally occurring lactose from the dairy base — no added sweetener, honey, fruit concentrate, or cane sugar contributes to that number. Sweetness in the flavored varieties comes from sucralose and natural flavoring, which is why added sugar stays at 0g across all five flavors.

The 24 oz Tub Format: Slightly Different Numbers

:ratio also sells a 24 oz resealable tub, marketed specifically as the “28g Protein” version. The higher protein number is a function of a larger serving size — 2/3 cup (roughly 170g) rather than the 5.3 oz cup — not a reformulation of the product.

The tub is a better value per gram of protein if you’re buying in bulk; the cup is more convenient for grab-and-go use. The per-gram protein density is essentially the same — you’re getting the same product in a different serving increment.

How :ratio Gets to 25g of Protein

Traditional Greek yogurt achieves its higher protein count (relative to regular yogurt) by straining out the whey, which concentrates the milk proteins in the remaining curd. Greek yogurt made this way typically delivers 12–15g of protein per 5.3 oz serving. :ratio takes a different approach: it runs nonfat milk through a membrane ultra-filtration process that separates and concentrates the milk proteins without losing the calcium, then adds whey protein concentrate on top. The combination — ultra-filtered milk + whey protein concentrate — is why the protein number reaches 25g when conventional strained Greek yogurt tops out around 15g at the same serving size. The trade-off is that :ratio is technically a “cultured dairy snack,” not a certified Greek yogurt, because the production process differs from the traditional straining method. Nutritionally the end result is comparable to Greek yogurt: a thick, protein-dense cultured dairy food with live active cultures, high calcium, and low lactose relative to conventional milk.

Flavor Comparison: Do the Macros Change?

All five current flavors carry the same core nutrition profile. The table below is sourced from brand and retailer label data for each variety.

The fruity flavors (Strawberry, Blueberry, Key Lime, Mixed Berry) use natural flavoring and sucralose rather than real fruit pieces or fruit puree — which is how they maintain 3g of total sugar across all flavors rather than the 8–12g you see in fruit-flavored conventional Greek yogurts. If you prefer actual fruit in your yogurt, stir in fresh berries; that lets you control the sugar addition yourself.

Head-to-Head: :ratio vs Other High-Protein Yogurt Cups

The comparison below covers the most direct competitors in the high-protein yogurt cup space, all in 5.3 oz (or close) serving sizes. Numbers reflect the vanilla or plain flavor for each brand to keep the comparison clean.

What the table shows: :ratio delivers the most protein of any cup in this comparison by a wide margin — 25g versus 15g for Oikos Triple Zero and 12g for Two Good. But it also carries the most calories (170), the most fat (3.5g), and the most cholesterol (45mg per cup) of the group, largely because whey protein concentrate adds some fat that you don’t get in a fat-free strained yogurt. The no-sweetener options — FAGE and Chobani plain — have naturally occurring sugars from lactose (7–8g) but no sucralose. Siggi’s Vanilla has added agave nectar, which is why its added-sugar number is higher. Protein per calorie: :ratio scores 14.7g of protein per 100 calories, Oikos Triple Zero 16.7g, FAGE Total 0% 18g. So :ratio is not the most calorie-efficient option for pure protein density — Oikos Triple Zero and FAGE Total 0% beat it on that metric — but :ratio has the highest absolute protein per cup, which matters if you want the most protein from a single container without eating two.

Is :ratio PROTEIN Yogurt Healthy? Who It’s For

What works in its favor:

• 25g of complete protein per cup — the highest of any mainstream yogurt cup we have verified. For context, a large egg has 6g of protein; a 5.3 oz cup of :ratio matches nearly four eggs.
• Zero added sugar across all five flavors — the 3g of total sugar is naturally occurring lactose, not sweetener that would otherwise show up as added sugar on the label.
• 20% of the Daily Value for calcium (250mg), which is meaningful for a snack-sized serving.
• Low sodium (100mg, 4% DV) — well below what you’d find in protein bars, which commonly run 200–300mg or more.

What to know before buying:

• Sucralose. :ratio uses sucralose as its non-caloric sweetener in all flavored varieties. If you specifically avoid artificial sweeteners, :ratio is not the right fit — Oikos Triple Zero (stevia), Siggi’s (agave), FAGE (no sweetener), and Chobani Plain (no sweetener) are alternatives. See our guide on protein sweeteners explained for context on sucralose vs. stevia vs. sugar alcohols.
• Carrageenan. The ingredient list includes carrageenan, a seaweed-derived thickener that some people prefer to avoid. This is a personal preference call — the FDA considers it safe — but it is worth noting if clean-label formulations matter to you.
• 3.5g of fat per cup. This is modest but higher than the 0g fat in Oikos Triple Zero or FAGE Total 0%. The fat comes from the whey protein concentrate rather than added oil; the small amount of sunflower oil in the ingredient list is secondary. For calorie-restricted diets, this is worth factoring in.
• Not technically Greek yogurt. Because the protein is concentrated via ultra-filtration and whey addition rather than straining, the product is labeled a “cultured dairy snack” rather than Greek yogurt. It still contains live active cultures.

Best fit: :ratio is ideal if you specifically want the most protein possible from a single snack-sized yogurt cup and are comfortable with sucralose. It works well as a post-workout recovery snack, a high-protein breakfast, or a filling afternoon snack when you need 25g of protein without cooking anything. For people hitting 150g+ protein daily who rely on convenient portable snacks, a single cup of :ratio covers a substantial portion of that target. If you want to minimize calories and are fine with 15g of protein rather than 25g, Oikos Triple Zero or Chobani Plain Nonfat are lower-calorie alternatives with the same zero-added-sugar profile. See our Oikos Triple Zero nutrition guide, Two Good yogurt breakdown, and highest protein-to-calorie snacks ranking for the full-picture comparison.

Frequently Asked Questions

How does :ratio PROTEIN yogurt have 25g of protein?

:ratio combines two protein-boosting techniques: ultra-filtered nonfat milk (which concentrates milk proteins by removing water and lactose through a membrane filtration process) and whey protein concentrate (added separately to boost the total further). Traditional Greek yogurt achieves its protein through straining, which typically yields 12–15g per 5.3 oz. The ultra-filtration plus whey approach pushes the number to 25g in the same cup size. The trade-off is a slightly different texture and the addition of whey protein concentrate as an ingredient rather than the protein coming entirely from the cultured milk base.

Is :ratio yogurt actually good for you?

It is a nutritionally dense snack — 25g of complete dairy protein, 20% of the daily calcium target, 0g of added sugar, and 170 calories. Those numbers compare favorably to most packaged high-protein snacks. The things worth knowing are that it contains sucralose (an artificial sweetener, FDA-approved, zero glycemic index) and carrageenan (a thickener some people prefer to avoid). If you want a high-protein yogurt with no artificial sweeteners, FAGE Total 0% (no sweetener) or Chobani Plain Nonfat (no sweetener) are alternatives, though both deliver less protein per cup (18g for FAGE, 15g for Chobani, versus :ratio’s 25g).

Is :ratio yogurt good for weight loss?

Yes, it can be an effective weight-loss snack. 25g of protein and 0g of added sugar at 170 calories supports satiety between meals without a large calorie cost. High-protein eating is consistently associated with reduced hunger and better weight management in the research literature. The sucralose used as a sweetener has zero calories and zero glycemic index. For the highest protein-to-calorie ratio among yogurt cups, Oikos Triple Zero (90 cal, 15g protein) slightly outperforms :ratio (170 cal, 25g protein) on a per-calorie basis — 16.7g vs. 14.7g of protein per 100 cal — but :ratio delivers more total protein per container, which may matter if satiety is the priority. See our best high-protein snacks for weight loss guide for the full comparison across categories.

Is :ratio yogurt lactose-free?

:ratio is not labeled lactose-free. The ultra-filtration process removes some lactose but does not eliminate it entirely — and unlike Fairlife’s process (which adds lactase enzyme to break down residual lactose), :ratio does not add lactase. The 3g of total sugar per cup is mostly residual lactose from the dairy base. In practice, many lactose-intolerant people tolerate :ratio fine because the lactose content per serving is low (much lower than conventional whole milk or regular yogurt), but it is not certified lactose-free. If you need a fully lactose-free dairy protein source, see our Fairlife Core Power breakdown for the RTD shake option, or choose a lactase supplement alongside :ratio.

Where can I buy :ratio PROTEIN yogurt?

:ratio is widely stocked at Target, Walmart, Kroger, Safeway, H-E-B, Publix, and most major grocery chains. The 5.3 oz single-serve cups are typically in the yogurt section; the 24 oz tub is sometimes shelved separately with larger format yogurt and cottage cheese. Availability of individual flavors varies by store; Vanilla and Strawberry are the most consistently stocked. :ratio is not currently available through Amazon Fresh in all regions, so your best option is in-store pickup or a standard grocery delivery service.

How does :ratio compare to Oikos Pro or Oikos Triple Zero?

Oikos Triple Zero (90 cal, 15g protein, 0g sugar, stevia) is the lowest-calorie option and the one to pick if calories are the primary constraint — it delivers protein at the most efficient calorie cost (16.7g per 100 cal vs. :ratio’s 14.7g per 100 cal). But :ratio wins on absolute protein per container — 25g versus 15g — which matters if you’re trying to hit a high daily protein target with one snack rather than spreading it across multiple smaller ones. Oikos Pro, Danone’s newer ultra-filtered line, sits between the two: approximately 20g of protein at around 100 calories per 5.3 oz. If your main goal is maximum protein in a single cup, :ratio is the pick. If your goal is maximum protein efficiency per calorie and you are comfortable eating smaller amounts, Oikos Triple Zero or FAGE Total 0% serve that better.

Bottom line: :ratio PROTEIN yogurt delivers the highest protein count of any mainstream yogurt cup we’ve verified — 25g per 5.3 oz container, 170 calories, zero added sugar — achieved through ultra-filtered milk and whey protein concentrate. The sweetener is sucralose (which rules it out for anyone avoiding artificial sweeteners), and the product includes carrageenan as a thickener. If neither is a concern and you want the most protein from a single grab-and-go yogurt cup, :ratio is the clearest choice. For a lower-calorie alternative at 15g of protein, Oikos Triple Zero (stevia, no sucralose) is the next best option.
