Is Siggis Organic? Inside Siggi’s Skyr Yogurt Ingredients

Siggis yogurt is not certified organic. The Icelandic-style skyr brand, founded in 2005, relies on sourcing standards rather than a formal organic label: its milk comes from farms that pledge not to use artificial growth hormones such as rBST or rBGH, every product uses non-GMO ingredients, and the ingredient lists stay short with no artificial sweeteners, flavors, or preservatives. Shoppers who check the carton will not find a USDA Organic seal, but Siggi’s own FAQ pages confirm these quality commitments in detail.

Is Siggi’s Organic Certified?

No, Siggi’s is not certified organic by the USDA or any other third-party organic body. The company has stated plainly on its FAQ pages that it has chosen not to pursue organic certification, a position that held true as of September 2026. That choice does not mean the brand ignores sourcing quality; it means Siggi’s built its own set of standards instead of paying for and maintaining a certification program.

Checking Siggi’s own FAQ page confirms this directly. Siggi’s Canada addresses the same question, and the answer matches word for word. Neither the Canadian nor the American packaging carries a USDA Organic or Canada Organic seal, which are the marks shoppers should look for when certification is the deciding factor.

What Sourcing Standards Does Siggi’s Follow Instead?

Siggi’s replaces organic certification with three sourcing pledges: hormone-free milk, non-GMO ingredients, and minimal processing. Every farm supplying the brand agrees not to use artificial growth hormones such as rBST or rBGH, and the milk itself comes from grass-fed cows. In Canada, the entire skyr line is made from 100 percent Canadian milk, sourced under the same hormone-free pledge.

Ingredient lists stay short across the lineup. Siggi’s avoids artificial sweeteners, artificial coloring, and preservatives in its dairy skyr, and every product line uses non-GMO ingredients. That combination is why many shoppers assume the brand is organic before they check the label, since the sourcing story sounds similar even though the certification is absent.

rBST and rBGH are both names for a synthetic hormone once injected into dairy cows to boost milk output. Farms that supply Siggi’s pledge to skip that hormone entirely, a commitment the brand documents alongside its grass-fed claim rather than folding it into a certification badge. Shoppers who care about hormone-free dairy get that assurance directly from the label copy and the company FAQ, even without a green USDA seal on the lid.

Formal organic certification also carries costs that a hormone-free pledge does not. A dairy brand seeking USDA Organic status must convert its supplying farms to organic feed and pasture management, submit to annual inspections, and document the full chain from farm to carton. Siggi’s sourcing rules cover hormone use and genetic modification, but they stop short of that broader conversion, which is one reasonable explanation for why the company has not pursued the seal.

What’s in Siggi’s Skyr Yogurt?

Siggi’s ingredient lists vary by product line, but all of them lean short and recognizable. The dairy skyr uses cultured milk and live active cultures as its base, while the newer lower-sugar and plant-based lines add a few functional ingredients for texture and sweetness. Four product categories make up the current lineup: plain and flavored dairy skyr, plant-based alternatives, drinkable yogurt, and squeezable pouches for kids. Three representative products follow below, starting with the plain skyr.

Plain Whole Milk Skyr Ingredients

The 24-ounce Plain Whole Milk Skyr contains just two ingredient categories: cultured pasteurized whole milk and five live active culture strains, Streptococcus thermophilus, Lactobacillus delbrueckii bulgaricus, Bifidobacterium lactis, Lactobacillus acidophilus, and Lactobacillus delbrueckii lactis. A three-quarter-cup serving delivers 18 grams of protein, 170 calories, 7 grams of fat, 8 grams of carbohydrates, and 170 milligrams of calcium. Those numbers reflect the traditional skyr process, which concentrates protein far more than standard yogurt making does.

Lower Sugar Vanilla Skyr Ingredients

A 5.3-ounce package of Lower Sugar Vanilla Skyr carries a longer ingredient list built around function rather than filler. It combines pasteurized skim milk, pasteurized cream, milk protein concentrate, native corn starch, natural flavor, fruit pectin, fruit and vegetable juice concentrates for color, Stevia Reb M, sea salt, and live active cultures. The stevia extract and juice concentrates replace the added sugar and artificial dye that many flavored yogurts rely on, which keeps the sugar content down without switching to an artificial sweetener.

Plant-Based Yogurt Alternative Ingredients

Siggi’s dairy-free line swaps milk for a proprietary blend of coconut milk, macadamia nuts, and pea protein. Coconut oil, tapioca flour, fruit pectin, and live active cultures round out the formula, and the line carries Non-GMO Project Verified certification specifically, unlike the dairy skyr, which is non-GMO but not third-party verified. Anyone with a tree nut allergy should treat this line as off-limits, since coconut and macadamia are both tree nuts and appear directly in the ingredient list.

How Does Siggi’s Compare to Organic Standards?

Several standards shoppers associate with organic food show up here, even without the certification. The table below lines up what Siggi’s documents against the USDA Organic label shoppers may expect to see.

Attribute	Status
USDA Organic Certified	No
Grass-Fed Milk	Yes
rBST/rBGH-Free Milk	Yes
Non-GMO Ingredients	Yes
Artificial Sweeteners	None used
Artificial Flavors	None used
Preservatives	None used
Milk Used Per Batch	About 4 times regular yogurt

That mix explains the confusion shoppers feel at the store. Siggi’s checks almost every box associated with clean sourcing, hormone-free milk, non-GMO ingredients, no artificial additives, yet it stops short of paying for and maintaining the paperwork trail that organic certification requires. Whether that gap matters comes down to whether a shopper needs the seal itself or just the sourcing practices the seal is meant to guarantee.

What Makes Skyr Different from Regular Yogurt?

Skyr is a traditional Icelandic dairy product that uses roughly four times as much milk as regular yogurt to make the same volume of finished product. That higher milk-to-yogurt ratio is what gives skyr its thick texture and unusually high protein count compared to typical American yogurt cups.

Siggi’s skyr carries 25 to 50 percent less sugar than many other yogurt brands, largely because the company avoids the added sugar and fruit syrups common in flavored yogurt cups. The straining process concentrates protein and reduces lactose along with liquid whey, which is part of why skyr tends to sit better with people who find regular yogurt too watery or too sweet.

People who find regular yogurt hard to digest sometimes tolerate skyr better because of that straining step, though skyr still contains dairy and is not lactose-free. Anyone managing a diagnosed lactose intolerance or dairy allergy should check with a doctor before treating skyr as a substitute, since concentrating the protein does not eliminate lactose entirely.

How Much Protein Does Siggi’s Deliver per Calorie?

A three-quarter-cup serving of Plain Whole Milk Skyr packs 18 grams of protein into 170 calories, which works out to roughly 42 percent of the calories coming from protein. Protein carries about 4 calories per gram, so 18 grams multiplies out to 72 calories from protein alone, and 72 divided by 170 lands at about 0.42, or 42 percent.

That ratio sits well above most flavored yogurt cups, which typically lean on added sugar for calories rather than protein. Readers watching protein intake for a specific medical or dietary reason should still confirm targets with their doctor, since individual needs vary by weight, activity level, and any underlying condition.

Fat and carbohydrates make up the rest of the calories in that same serving. Seven grams of fat contribute about 63 calories at 9 calories per gram, and 8 grams of carbohydrates add roughly 32 calories at 4 calories per gram. Adding those figures to the 72 calories from protein lands close to the full 170-calorie total, within normal rounding.

Who Owns Siggi’s and How Did It Start?

Icelandic entrepreneur Siggi Hilmarsson founded the company in 2005, basing the recipe on a 1913 formula his mother found at a library in Reykjavik. By January 2008, Siggi’s had reached half of all Whole Foods locations nationwide, a fast expansion within just a few years of launch.

French dairy corporation Lactalis acquired Siggi’s in 2018. The company has continued to operate independently under that ownership since the acquisition closed.

How Can You Find Certified Organic Yogurt if That Matters to You?

Look for the USDA Organic seal directly on the container if organic certification is a requirement rather than a preference. That green and white seal only appears on products that passed inspection under the USDA National Organic Program, and it is the one marker that sourcing claims like grass-fed or hormone-free cannot substitute for.

Reading the ingredient panel alongside the seal still matters, since a product can be certified organic and still contain added sugar or a long list of flavorings. Shoppers who want both organic certification and a short ingredient list will need to compare labels directly at the store, because Siggi’s sourcing standards do not currently include that specific seal. You can also compare USDA organic yogurt options on Amazon before checking labels in person.

A quick four-step check at the shelf covers most of what matters:

1. Flip the carton over and look for the USDA Organic seal near the nutrition panel rather than on the front label alone.
2. Read the ingredient list for the word organic before specific ingredients, since a product can use that word without carrying the full seal.
3. Check the sourcing claims separately, since grass-fed, non-GMO, and hormone-free are each independent statements that do not require organic certification.
4. Compare the sugar content across brands, since organic certification says nothing about how much sugar a flavored yogurt contains.

This guide does not compare retail prices, since costs vary by store, package size, and region.

Frequently Asked Questions

Does Siggi’s Use Grass-Fed Milk?

Yes, Siggi’s sources 100 percent grass-fed milk for its dairy skyr line. Grass-fed status is a separate claim from organic certification, and Siggi’s documents it directly on its website and packaging. That distinction matters for anyone comparing labels side by side at the store.

Is Siggi’s Yogurt Non-GMO?

Every Siggi’s product uses non-GMO ingredients, and the plant-based line carries formal Non-GMO Project Verified certification. Dairy skyr lines state non-GMO sourcing as well, though that claim is not backed by the same third-party verification badge. Shoppers who need formal verification should look for the Non-GMO Project butterfly specifically, since not every non-GMO claim carries that badge.

Does Siggi’s Contain Artificial Sweeteners?

No, Siggi’s does not use artificial sweeteners in any of its skyr products. The lower-sugar line uses Stevia Reb M, a plant-derived sweetener, instead of sugar alcohols or synthetic sweeteners. That choice keeps the ingredient list shorter than many diet or zero-sugar yogurt brands that rely on sugar alcohols.

Who Makes Siggi’s Yogurt Now?

French dairy corporation Lactalis owns Siggi’s after acquiring the company in 2018. Founder Siggi Hilmarsson’s original recipe and brand identity remain in place, and the company continues to operate independently within the larger Lactalis portfolio. Production and sourcing standards have stayed consistent since the acquisition, based on the company’s own public statements.

Does Siggi’s Plant-Based Yogurt Contain Nuts?

Yes, the plant-based line contains coconut and macadamia nuts as part of its base blend, alongside pea protein. Anyone with a tree nut allergy should avoid this line and stick to the dairy skyr instead, since coconut and macadamia both count as tree nuts on an allergen label. Checking the allergen statement on the package is still the safest step before buying.

What Other Products Does Siggi’s Sell Besides Plain Skyr?

Beyond plain and flavored dairy skyr, Siggi’s sells plant-based alternatives, drinkable yogurt, and squeezable pouches aimed at kids. Each line follows the same short-ingredient approach, though exact ingredients shift depending on whether the base is dairy or plant-based. Drinkable formats and kid-focused pouches follow the same non-GMO and hormone-free sourcing as the core skyr line.

Siggi’s earns trust through hormone-free milk, non-GMO sourcing, and short ingredient lists rather than an organic seal. Shoppers who need the USDA Organic label for personal or dietary reasons should look elsewhere, but anyone comparing real sourcing practices will find Siggi’s standards hold up well against many products that do carry the certification. The label copy, not the certification, ends up telling the fuller story for this particular brand.
