Orgain Protein Shake Nutrition Facts (2026): All 5 Formulas Compared — Which One Is Actually High Protein?

All 5 Orgain RTD Protein Shake Formulas: Side-by-Side Comparison

All figures are per bottle as sold. Verified from Orgain’s official product pages, Costco and Amazon listings, and FoodData Central records. The 30g Milk Protein formula is Costco-exclusive and may not appear at other retailers.

The gap between the Classic (250 cal, 16g protein, 12g sugar) and the 30g Milk Protein formula (160 cal, 30g protein, 1g sugar) is dramatic. Both share the Orgain label and sell at the same warehouse club. If your goal is high protein with controlled calories and sugar, only the three higher-tier formulas qualify by modern standards.

Orgain Classic Organic Nutritional Shake: 16g Protein, 250 Calories

The original Orgain product — launched as a hospital-grade nutritional supplement for people who needed convenient calories and protein in one drink. The Classic formula delivers 16g of protein from a whey and casein blend at 250 calories, 12g of sugar, and 28g of total carbohydrates. By 2026 standards for high-protein snacks, 16g at 250 calories is a weak protein-to-calorie ratio — Premier Protein delivers 30g of protein at 160 calories in a comparable bottle size. The Classic Orgain is not a bad product; it genuinely serves older adults and people recovering from illness who need calorie-dense nutrition. But it is not the right choice for athletes or anyone optimizing lean protein intake.

• Best for: seniors, illness recovery, people who need calorie-dense nutrition and find lighter protein shakes too low-calorie
• Skip if: you’re tracking macros, targeting high protein per calorie, or watching sugar intake
• ASIN: B003FDG4K4

Orgain Plant-Based Nutritional Shake: 16g Protein, 220 Calories, Dairy-Free

The vegan version of the Classic, using a pea and brown rice protein blend instead of whey and casein. At 220 calories and 16g of protein with 9–10g of sugar per bottle, it is slightly leaner than the Classic but in the same nutritional tier. This is Orgain’s answer for plant-based buyers who want an Ensure or Boost equivalent in dairy-free format. For plant-based athletes wanting more protein, the 26g Grass-Fed formula does not have a direct vegan counterpart in the Orgain RTD lineup — the plant-based tier stops at 16g.

• Best for: vegans and dairy-free buyers who need a nutritional shake format; not optimized for high-protein athletic use
• ASIN: B00JTX7SH2

Orgain Clean Grass-Fed Whey Protein Shake: 20g Protein, 130 Calories

This is where Orgain’s lineup pivots meaningfully. The 20g Grass-Fed Whey formula delivers 20g of protein at only 130 calories — a protein density of 15.4g per 100 calories that competes directly with the leaner tier of RTD protein shakes. Total carbs are approximately 9g with about 3g of added sugar per bottle. The protein source is grass-fed whey protein concentrate, and the product carries USDA Certified Organic and no artificial ingredient certifications. This is the formula that built Orgain’s reputation among fitness buyers. At 130 calories, it’s one of the lowest-calorie high-protein RTDs available at mainstream retail.

• Best for: calorie-controlled muscle building, people wanting a certified organic RTD, post-workout when caloric surplus isn’t the goal
• ASIN: B01CI57V2O

Orgain Grass-Fed 26g Protein Shake: 26g Protein, 160 Calories, 14 fl oz

The 26g formula is the largest bottle in Orgain’s lineup at 14 fl oz, delivering 26g of protein at 160 calories with 1g of sugar and 0g of added sugars. Total carbs are 7g. This is Orgain’s mainstream athlete product — organic, grass-fed, no artificial ingredients, and a competitive 16.25g protein per 100 calories. The larger serving size (14 fl oz vs. 11 fl oz for competitors in the same calorie range) gives more volume and perceived satiety per bottle. Available at most Target, Whole Foods, Sprouts, and Costco locations where Orgain is stocked. For more RTD options at this calorie tier, see our best protein drinks of 2026 guide.

• Best for: athletes wanting an organic RTD with meaningful protein; buyers who prefer a larger bottle and don’t need the 30g tier
• ASIN: B01MZE5Y50

Orgain 30g Milk Protein Shake (Costco Exclusive): Best Orgain for High Protein

The 30g Milk Protein formula is Orgain’s highest-tier RTD and a Costco-exclusive product. Per 11 fl oz bottle: 30g of protein, 160 calories, 7g of carbs, 1g of sugar, 0g of added sugars, 3g of fat. The protein source is A2 ultra-filtered milk protein — a filtered milk protein concentrate from A2 beta-casein cows, positioned as easier to digest for some dairy-sensitive individuals. At approximately $1.67 per bottle in an 18-pack, this formula competes directly with Premier Protein (30g, 160 cal, ~$1.37 at Walmart) and beats Fairlife Core Power Standard (30g, 230 cal, ~$3.29) on both calories and price. The organic certification is a differentiator neither Fairlife nor Premier Protein offers.

• Best for: Costco members who want maximum protein per calorie with an organic certification; anyone who wants Premier Protein’s nutrition at organic quality
• Key metric: 18.75g protein per 100 calories — best ratio in the entire Orgain lineup

Orgain vs Fairlife Core Power vs Premier Protein

For buyers specifically targeting high protein, here is how the top-tier Orgain formulas compare to the two market leaders at mainstream US retail:

Premier Protein wins on price at most retail. Orgain 30g wins on organic certification at comparable protein and calorie efficiency. Fairlife Core Power Elite wins on maximum protein per bottle (42g) but costs roughly twice as much and delivers 70 more calories.

Which Orgain Formula Should You Buy?

• Maximum protein per calorie (Orgain only): 30g Milk Protein at Costco — 30g at 160 cal, best ratio in the lineup
• Certified organic, 20g protein is enough: Clean Grass-Fed Whey — 130 calories, cleanest macros per calorie in the lineup
• Best per-bottle value at conventional retail: Grass-Fed 26g — larger bottle, 26g protein, widely available
• Vegan or dairy-free: Plant-Based 16g — the only dairy-free Orgain RTD; accept that 16g is modest by athletic standards
• Calorie-dense nutrition (older adult, illness recovery): Classic 16g — designed for this use case; 250 calories per bottle is the feature, not a flaw

Frequently Asked Questions

Is Orgain protein shake good for building muscle?

The upper-tier Orgain formulas (20g Grass-Fed Whey, 26g Grass-Fed, 30g Milk Protein) provide complete dairy protein with adequate leucine for muscle protein synthesis. The Classic and Plant-Based formulas at 16g are less efficient. Research generally supports consuming 20–40g of protein per meal to maximize muscle protein synthesis response; the 30g Milk Protein Costco formula meets that threshold in a single bottle.

How does Orgain compare to Premier Protein?

The Orgain 30g Milk Protein Costco formula matches Premier Protein almost exactly: both deliver 30g of protein at 160 calories with 1g of sugar in an 11–11.5 fl oz bottle. Orgain is USDA Certified Organic and uses A2 ultra-filtered milk protein; Premier Protein is not organic and uses milk protein concentrate and calcium caseinate. Premier Protein is typically cheaper ($1.37/bottle at Walmart vs. ~$1.67 at Costco for Orgain). For buyers who want organic credentials, Orgain wins. For buyers who prioritize price, Premier Protein wins. For full Premier Protein nutrition data, see our Premier Protein nutrition facts guide.

Is Orgain protein shake keto-friendly?

The 20g Grass-Fed Whey (9g carbs), 26g Grass-Fed (7g carbs), and 30g Milk Protein (7g carbs) formulas are keto-compatible at low net carbs and 0–3g of sugar per bottle. The Classic (28g carbs, 12g sugar) and Plant-Based (24g carbs, 9g sugar) formulas are not appropriate for ketogenic diets.

Is the Orgain Classic formula high in sugar?

Yes, relative to other protein shakes — 12g of sugar per 11 fl oz bottle. Premier Protein has 1g of sugar, and the Orgain 30g Milk Protein formula also has 1g. The Classic uses organic cane sugar and organic tapioca syrup as sweeteners. If you’re watching sugar intake, the 26g or 30g Orgain formulas are significantly better choices.

Where can I buy Orgain 30g protein shakes?

The 30g Milk Protein formula is currently available exclusively at Costco. The 20g Grass-Fed Whey and 26g Grass-Fed formulas are available at Target, Whole Foods, Sprouts, and online via Amazon. The Classic and Plant-Based formulas are the most widely distributed and appear at Walmart, Costco, Target, and mainstream grocery chains.

Bottom line: Orgain’s five RTD formulas serve very different buyers. The Classic and Plant-Based at 16g of protein are wellness and nutritional supplement products, not high-protein athletic shakes. The 20g Grass-Fed Whey, 26g Grass-Fed, and 30g Milk Protein Costco formulas are where Orgain competes directly with Premier Protein and Fairlife — delivering comparable protein at comparable calories with an organic certification neither competitor offers. If you’re shopping Orgain for high protein, go directly to the top three tiers and skip the Classic unless you specifically need the extra calories.
