Is Chobani Greek Yogurt Lactose Free? Boost and Glucerna Too

AvatarByEric Dawson Milk & Dairy

Chobani Greek yogurt is lactose-free only in specific product lines. Zero Sugar Greek Yogurt, High Protein drinks, Complete shakes and Oatmilk products from Chobani contain no lactose, the result of a two-step process that filters most of the natural sugar out of milk before yogurt cultures consume what remains. Regular Chobani Greek yogurt works differently: it carries naturally occurring lactose, usually under 5% of the product, an amount many people with mild sensitivity tolerate without issue. A similar split shows up across the shelf. Boost and Glucerna shakes are suitable for lactose intolerance but not fully lactose-free, and Muscle Milk Pro 33 uses ultra-filtered milk that cuts lactose to less than 1 gram per bottle rather than removing it entirely.

Is Chobani Greek Yogurt Lactose Free

Only four Chobani lines are lactose-free: Zero Sugar Greek Yogurt, High Protein drinks, Complete shakes and the Oatmilk range. Every other Chobani Greek yogurt, including the plain and flavored cups most shoppers know, still contains a small amount of naturally occurring lactose.

Which Chobani Products Are Fully Lactose-Free

Chobani removes lactose from these lines through ultra-filtration, a process that passes non-fat milk through a fine membrane. Small molecules such as lactose and water pass through and get discarded, while the larger casein and whey proteins stay behind and become more concentrated. Yogurt cultures then consume whatever sugar remains during fermentation, which is how Chobani reaches its zero sugar count. FoodNavigator described the approach as an industry first when Chobani launched the Zero Sugar line, noting that the finished yogurt carries 60 calories per 5.3 ounce serving along with 11 to 12 grams of protein and live cultures. Chobani Complete shakes use the same filtration logic and deliver 25 grams of complete protein per drink, and the entire Oatmilk range skips dairy altogether, which also makes it lactose-free.

Why Regular Chobani Yogurt Still Contains Lactose

Plain and flavored Chobani Greek yogurt is fermented rather than filtered, so it keeps a naturally occurring dose of lactose, typically under 5% of the product. Fermentation breaks down some of the milk sugar, which is why yogurt in general sits lower in lactose than a glass of milk, but the process does not eliminate it. People with a mild sensitivity often handle that smaller amount without symptoms, while those with a more severe intolerance or galactosemia should treat regular Chobani yogurt as a dairy product that contains lactose, not as a lactose-free one. Chobani’s lactose-free lines are sold at Target, Amazon and through Chobani’s own site, so shoppers do not need a specialty store to find them.

Is Glucerna Lactose Free

Glucerna shakes and bars are suitable for lactose intolerance, but Abbott does not market any Glucerna product as lactose-free. Every variety contains milk ingredients that contribute a small amount of lactose.

Abbott’s own FAQ for the brand confirms that Glucerna shakes are gluten-free and formulated to work for people managing lactose intolerance, a distinction the company draws carefully because its main audience is people managing diabetes and blood sugar, not dairy allergies. The Glucerna Protein Smart Shake, for example, packs 30 grams of protein and comes in a Homemade Vanilla flavor, and it carries the same milk-ingredient caveat as the rest of the lineup. Glucerna bars follow the same rule: milk ingredients are present, the lactose amount stays small, and the product is not labeled lactose-free. Abbott specifically advises against Glucerna for anyone with galactosemia, a rare metabolic condition where the body cannot process galactose, one of the two sugars that make up lactose. Exact gram counts for Glucerna’s lactose content are not published the way Boost’s are, so anyone with a severe intolerance should call Abbott’s consumer line or check with a doctor before relying on label language alone.

Is Boost Lactose Free

Boost is not lactose-free. Most Boost drinks contain less than 0.5 gram of lactose per 8 fluid ounce serving, a level Nestle considers suitable for lactose intolerance but not free of lactose entirely.

Nestle Medical Hub confirms that Boost Original carries that same 0.5 gram guideline and is appropriate for lactose intolerance, though not for galactosemia or a milk allergy. Boost Very High Calorie, a denser formula built for people who need extra calories in a small volume, packs 530 calories and 22 grams of protein into 8 fluid ounces along with 26 vitamins and minerals, and it carries the same lactose profile as the standard line. Every Boost product includes milk protein concentrate, the ingredient responsible for the residual lactose, so the brand remains unsuitable for anyone avoiding milk protein altogether rather than just lactose. ScienceInsights, reviewing the Boost and Ensure lineups together, confirmed that neither brand currently sells a fully dairy-free nutritional shake in the United States.

Which Boost Products Are Not Suitable for Lactose Intolerance

Three Boost formulas fall outside even the suitable for lactose intolerance category: Boost Max Nutritional Shake, Boost Glucose Control Max 30g Protein Nutritional Drink and Boost Advanced Nutritional Drink. These denser, higher-protein formulas carry more lactose than the standard line, so shoppers managing intolerance should check the label on these three specifically rather than assume every Boost product behaves the same way.

Is Muscle Milk Lactose Free

Muscle Milk is marketed as lactose-free, but the standard lines still carry a trace amount. Pro 33 specifically uses ultra-filtered milk that reduces lactose to below 1 gram per bottle, well under the roughly 12 grams found in the same volume of regular milk, yet that is a reduction rather than a complete removal.

How Ultra-Filtration Removes Lactose from Milk

Ultra-filtration pushes milk through a membrane fine enough to let small molecules, namely lactose and water, pass through while it holds back the larger casein and whey proteins along with the fat. The result keeps roughly the natural 80/20 casein-to-whey ratio found in ordinary milk, part of why Muscle Milk retains its protein profile even after the process strips out most of the sugar. Muscle Milk’s 2026 reformulation applies this filtration across its ready-to-drink shakes and adds no artificial sweeteners, flavors or colors, which the brand’s parent, Gatorade, has positioned as the first national ready-to-drink protein shake built on ultra-filtered milk.

Is Muscle Milk Pro 33 Different from Standard Lines

Muscle Milk Pro 33 and the standard Genuine and ZERO lines share the same ultra-filtration process and the same sub-1-gram lactose result, so the real difference is the protein and sugar numbers rather than the lactose count. Pro 33 delivers 33 grams of protein and 3 grams of sugar in an 11 fluid ounce serving, aimed at people who want a higher protein dose per bottle. Muscle Milk Plant Protein sits apart from both: it swaps dairy for pea, brown rice and canola protein, which makes it genuinely dairy-free and lactose-free rather than just low in lactose. None of the dairy-based Muscle Milk lines work for vegans or for anyone with a casein or whey allergy, since ultra-filtration concentrates those proteins instead of removing them.

How Chobani, Boost, Glucerna and Muscle Milk Compare

Side by side, only three product groups are genuinely lactose-free: Chobani’s Zero Sugar, High Protein and Complete lines, the Chobani Oatmilk range, and Muscle Milk Plant Protein. Everything else on this list is a low-lactose option rather than a lactose-free one.

Brand Product Line Lactose Status Lactose per Serving Suitable for Lactose Intolerance Dairy-Free
Chobani Zero Sugar Greek Yogurt Lactose-free 0g (as of September 2026) Yes No, contains milk proteins
Chobani High Protein drinks Lactose-free 0g (as of September 2026) Yes No, contains milk proteins
Chobani Regular Greek yogurt Contains lactose Under 5% naturally occurring Usually, depends on sensitivity No
Boost Original, Very High Calorie, High Protein Suitable for lactose intolerance Under 0.5g per 8 fl oz Yes No
Boost Max, Glucose Control Max, Advanced Not suitable for lactose intolerance Not published No No
Glucerna Shakes and bars Suitable for lactose intolerance Small amount from milk ingredients Yes No
Muscle Milk Pro 33 and standard lines Marketed lactose-free, trace lactose present Under 1g per 11 fl oz bottle Yes No
Muscle Milk Plant Protein Lactose-free 0g (as of September 2026) Yes Yes

I would choose a Chobani Zero Sugar yogurt or High Protein drink over Boost, Glucerna, or Muscle Milk if I needed the clearest lactose-free option. The difference between zero lactose and a small residual amount matters more to me than a broad claim that a product is suitable for intolerance. Muscle Milk Pro 33 has less than 1 gram per bottle and Boost has less than 0.5 gram per serving, but neither gives the same certainty as Chobani’s zero-lactose lines. I would reserve the lower-lactose choices for mild sensitivity.

When blood sugar management and a higher-protein shake are the priority, Glucerna Protein Smart Shake fits the article’s discussion of 30 grams of protein, while its milk ingredients still matter for severe lactose sensitivity. For a standard ready-to-drink nutrition option with the small residual lactose described above, BOOST Original Nutritional Drink suits people who tolerate limited lactose but need to avoid milk allergy products.

What Suitable for Lactose Intolerance Really Means

The phrase suitable for lactose intolerance means a product’s lactose level is low enough that most people who lack sufficient lactase enzyme can drink it without symptoms, even though the product still contains dairy. That label is not the same promise as lactose-free, which means the lactose has been reduced to effectively zero.

A worked comparison shows the gap. An 8 fluid ounce serving of Boost carries under 0.5 gram of lactose, while the same volume of regular milk carries roughly 12 grams, so Boost’s dose comes to about 4% of what a full glass of milk delivers. Muscle Milk Pro 33 tells a similar story in an 11 fluid ounce bottle: under 1 gram of lactose against the 12 grams or so in an equivalent amount of regular milk, a reduction of more than 90%. Someone with mild to moderate intolerance rarely reacts to a dose that small. A person with a severe intolerance, a celiac-adjacent sensitivity or galactosemia may still react to a gram or half a gram, which is why Abbott, Nestle and Muscle Milk’s parent company all stop short of calling these products lactose-free despite the low numbers.

What to Do if a Product Still Upsets Your Stomach

Start by checking the label for milk protein concentrate, milk ingredients, whey or casein, since any of those signal the small residual lactose that shows up even in products marketed as suitable for intolerance. If symptoms continue, switch to a line that is genuinely lactose-free rather than merely low in lactose.

  1. Read the ingredient panel first. Milk protein concentrate, whey protein concentrate or nonfat milk near the top of the list means the product carries some lactose, even if the front label says suitable for lactose intolerance.
  2. Try a smaller serving. Splitting a shake or yogurt cup across a day can keep the lactose dose under the threshold that triggers symptoms for many people with mild intolerance.
  3. Switch to a confirmed dairy-free line. Chobani Oatmilk, Chobani’s Zero Sugar and High Protein lines, and Muscle Milk Plant Protein are the options on this list built without dairy or with lactose fully removed.
  4. Talk with a doctor before changing a medical nutrition plan. Boost and Glucerna are often used alongside a specific calorie or blood sugar target, so anyone on one of these products for a medical reason should check with a doctor or dietitian before swapping formulas.

Frequently Asked Questions

Are Boost Shakes Completely Dairy-Free?

No. Every current Boost formula in the U.S. market contains milk protein concentrate, and Nestle has not released a fully dairy-free Boost shake. ScienceInsights confirmed the same gap exists across the broader Boost and Ensure lineup as of 2026.

Can People with Galactosemia Drink Glucerna or Boost?

Neither is recommended. Abbott advises against Glucerna for anyone with galactosemia, and Nestle gives the same caution for Boost, since both still contain milk-derived lactose that the condition prevents the body from processing.

Is Muscle Milk Safe for a Milk Protein Allergy?

No. Ultra-filtration reduces lactose, but it concentrates rather than removes casein and whey, the two proteins responsible for a milk allergy. Anyone with a diagnosed dairy protein allergy should avoid every dairy-based Muscle Milk line, including Pro 33.

What Is Muscle Milk Plant Protein, and Is It Lactose-Free?

Muscle Milk Plant Protein is a separate, dairy-free line built on pea, brown rice and canola protein instead of milk. It contains no lactose and no dairy, which makes it the one Muscle Milk option that works for vegans and for people avoiding dairy protein entirely.

Does Chobani Make Any Dairy-Free Products?

Yes. The Chobani Oatmilk range replaces dairy with oats, so it is both lactose-free and dairy-free. Chobani’s Zero Sugar, High Protein and Complete lines are lactose-free but still contain milk proteins, so they do not count as dairy-free.

The pattern across all four brands stays consistent. Filtration and fermentation can push lactose down to a trace amount, but suitable for lactose intolerance and lactose-free describe two different things. Shoppers with a mild sensitivity have plenty of options across Chobani, Boost, Glucerna and Muscle Milk, while anyone with a severe intolerance, a milk allergy or galactosemia should stick to the handful of lines built without lactose: Chobani’s Zero Sugar and Oatmilk products, Chobani High Protein and Complete drinks, and Muscle Milk Plant Protein.
