Is Siggi's Yogurt Clean?

📅 Updated February 2026⏱ 4 min readNEW
⚡

TL;DR

Siggi's is one of the cleanest yogurt brands on the market. By using traditional Icelandic straining methods, their skyr naturally concentrates protein and eliminates the need for artificial gums. While their flavored and plant-based lines contain a small amount of cane sugar, they are dramatically cleaner than mainstream competitors.

🔑 Key Findings

1

Siggi's traditional skyr contains 15 to 18 grams of protein per 5.3oz cup.

2

Plain dairy varieties use exactly two ingredients: pasteurized milk and live active cultures.

3

Flavored varieties contain roughly 4 to 8 grams of added cane sugar, about half the amount of conventional brands.

4

The plant-based line avoids artificial gums, utilizing pea protein and coconut milk to deliver 10 grams of protein.

The Short Answer

Siggi's is a clean, highly recommended brand. Whether you're reaching for their traditional Icelandic skyr or their newer coconut-based line, they deliver on their promise of "simple ingredients, not a lot of sugar."

By using authentic straining methods that require four times the milk of regular yogurt, Siggi's packs 15 to 18 grams of protein into a single serving naturally. Their plain versions contain just milk and probiotics, and even their flavored options manage to avoid the artificial thickeners, stevia, and excess sugars that plague the dairy aisle.

Why This Matters

Yogurt is almost universally marketed as a health food, but most mainstream brands are glorified desserts in disguise. Many contain up to 15 grams of added sugar and rely on synthetic gums, gelatin, or artificial sweeteners to fake a creamy texture. Is Yogurt Healthy

Siggi's changed the game by popularizing skyr, an Icelandic-style yogurt that relies on traditional straining to create thickness. This process naturally concentrates the casein protein and draws out the watery whey, completely eliminating the need for processed fillers. Is Skyr Healthier

Whether you consume their classic dairy cups or require dairy-free options, their ingredient transparency stands out. Even their flavored lines prove you can have a palatable product without dumping 12 grams of refined sugar into a tiny cup. Healthiest Yogurt

What's Actually In Siggi's Yogurt

  • Pasteurized Milk — The foundation of their traditional skyr. It provides natural slow-digesting protein and calcium without added synthetic hormones. Raw Vs Pasteurized Milk
  • Live Active Cultures — Essential probiotic strains like S. thermophilus and L. acidophilus that drive fermentation and support gut health.
  • Cane Sugar & Real Fruit — Found in their flavored varieties. While it is added sugar, Siggi's limits it to 4 to 8 grams per cup, keeping it well below the industry average. Sugar In Yogurt
  • Fruit Pectin — A natural fiber found in citrus and apples, used in flavored and plant-based lines to prevent separation. Thickeners In Yogurt
  • Coconut Cream & Pea Protein — The base for their dairy-free line. It provides an impressive 10 grams of plant-based protein, though it brings 7 grams of saturated fat from the coconut. Is Plant Yogurt Healthy
  • Macadamia Nut Butter & Tapioca Starch — Used exclusively in the plant-based line to create a creamy mouthfeel without resorting to inflammatory carrageenan or synthetic gums. Cleanest Plant Yogurt

What to Look For

Green Flags:

  • Zero artificial sweeteners — They never use stevia, aspartame, or sucralose to compensate for their low sugar content.
  • High protein density — With 15+ grams in dairy versions and 10 grams in plant-based, these yogurts provide actual, lasting satiety.

Red Flags:

  • Added sugars in flavored cups — While much lower than average, you are still consuming up to 8g of refined cane sugar in options like vanilla or mixed berry.
  • Saturated fat in the plant-based line — The coconut milk base in the dairy-free cups contains 35% of your daily saturated fat limit. Is Coconut Yogurt Healthy

FAQ

Is Siggi's healthier than Greek yogurt?

Yes, for most people. Skyr is strained even more than Greek yogurt, resulting in a denser texture, higher protein content, and a milder flavor without the sharp tang. Is Skyr Healthier

Does Siggi's plant-based yogurt have gums?

No. Unlike many vegan alternatives that rely on xanthan gum or carrageenan, Siggi's uses tapioca starch and fruit pectin to achieve its creamy texture naturally. Gums In Plant Yogurt

Are the live cultures in Siggi's actually beneficial?

Absolutely. The active bacterial strains survive the initial fermentation process and provide genuine, clinically backed probiotic benefits for your digestive system.

Oikos

Markets itself as 'zero sugar' but relies on stevia leaf extract for sweetness and chicory root fiber for texture. It also uses tapioca starch, indicating it isn't strained as thoroughly as authentic Greek brands.

Avoid
đŸš«

Yoghurt (Aussie Style)

Noosa

While ingredients are natural, the sugar content is astronomical—often 30g+ per tub (more than a Snickers bar). 'Aussie style' typically means unstrained, so it relies on honey and sugar for body rather than protein density.

Avoid
⚠

Greek Gods Yogurt

The Greek Gods

Labeled as 'Greek Style' rather than 'Greek Yogurt,' meaning it is often thickened with pectin rather than strained. This results in significantly lower protein (6-9g) compared to true strained options (15-18g).

Use Caution
đŸš«

Squishers (Organic)

Trader Joe's

Marketed for kids but packed with organic corn starch, carob bean gum, and gellan gum. Even organic versions of these thickeners suggest a low-quality milk base that lacks natural structure.

Danimals

The second ingredient is sugar, followed by modified food starch. It contains minimal protein (2g) and relies on 'natural flavors' to mask the lack of real fruit content.
