8 Best Protein Shakes for Gestational Diabetes

With gestational diabetes, breakfast can be the hardest meal of the day — your body is most insulin-resistant in the morning, meaning even a "healthy" bowl of oatmeal can send blood sugar soaring. A well-formulated protein shake can solve the morning glucose problem while also addressing increased protein needs during pregnancy.

Here are 8 options — from ready-to-drink bottles to protein powder for smoothies — that GD dietitians consistently recommend.

Ready-to-Drink Options

1. Fairlife Core Power Light — Best Overall RTD

Nutrition: 150 cal | 7g carbs | 0g sugar added | 26g protein
Price: ~$3.00–3.50/bottle
Flavors: Strawberry Banana, Chocolate, Vanilla

Fairlife uses ultra-filtered milk that removes most of the lactose and concentrates the protein, resulting in 26 grams of protein in just 7 grams of carbs — an extraordinary protein-to-carb ratio for a dairy product. No protein powder, no synthetic ingredients. It tastes like a thick milkshake because it essentially is one.

For GD-specific use, the Core Power Light (not the full-fat Elite at 42g protein) provides the best balance. The low carb count makes it excellent as a breakfast replacement or paired with a high-fat food for additional staying power.

Pros: Real food protein; very low carbs; high protein; widely available; no artificial sweeteners
Cons: Contains dairy (not for lactose-intolerant); glass-like bottle is breakable

2. OWYN Plant-Based Shake — Best Dairy-Free Option

Nutrition: 160 cal | 8g carbs | 6g sugar | 20g protein
Price: ~$4.00/bottle
Flavors: Dark Chocolate, Smooth Vanilla, Strawberry

OWYN (Only What You Need) is one of the cleanest plant-based RTD shakes available. Protein comes from peas, pumpkin seeds, and flax — all safe during pregnancy. No artificial colors, flavors, or sweeteners. The 8g carb count is very GD-friendly, and the taste is genuinely good for a plant-based option.

OWYN is also free of the top 9 allergens (no dairy, soy, tree nuts, peanuts, gluten), making it one of the most broadly accessible options on this list.

Pros: Allergen-free; clean plant-based ingredients; good taste; low carbs
Cons: More expensive; lower protein than Fairlife

3. Orgain Clean Protein Shake — Best Clean Whey RTD

Nutrition: 150 cal | 9g carbs | 1g sugar | 20g protein
Price: ~$3.00–3.50/bottle
Flavors: Creamy Chocolate Fudge, Vanilla Bean, Strawberry

Orgain uses whey protein isolate from organic milk with minimal additives. The ingredient list is clean — no carrageenan, no artificial flavors or colors. At 9g carbs and 20g protein, it fits neatly into most GD snack budgets. Widely available at Costco, Target, and online.

Pros: Organic sourcing; widely available; good value in bulk; clean label
Cons: Contains dairy; modest carb count still needs to be accounted for

4. Premier Protein Shake — Best Budget RTD

Nutrition: 160 cal | 5g carbs | 1g sugar | 30g protein
Price: ~$2.00–2.50/bottle (about $25 for 12-pack at Costco)
Flavors: Chocolate, Vanilla, Caramel, Peaches & Cream (15+ flavors)

Premier Protein is the most widely available high-protein RTD at an accessible price point. 30g protein in just 5g carbs is among the best protein-to-carb ratios on the market. The trade-off is a longer ingredient list and artificial sweeteners (sucralose, acesulfame potassium). For women prioritizing budget and protein quality without artificial-sweetener concerns, this is an excellent everyday option.

Pros: Highest protein at this price point; extremely low carbs; widely available including Walmart and Costco
Cons: Artificial sweeteners; longer ingredient list; not organic

Protein Powder Options (For Smoothies)

5. Garden of Life Raw Organic Protein — Best Clean Powder

Nutrition per serving: 110 cal | 2g carbs | 0g sugar | 22g protein
Price: ~$40–50 for 20 servings (~$2.00–2.50/serving)

Garden of Life Raw Organic Protein is certified organic, non-GMO, vegan, and made from a blend of sprouted grains, legumes, and seeds. The 2g carb count is excellent for adding to a smoothie that will also contain fruit. Sweetened with stevia. No artificial anything — ideal for women prioritizing clean, whole-food protein sources.

Pros: Certified organic; whole-food protein blend; very low carbs; non-GMO; stevia-sweetened
Cons: Mixed taste reviews; expensive per serving; plant proteins are slightly less bioavailable than whey

6. Vital Proteins Collagen Peptides — Best Complement Protein

Nutrition per serving: 70 cal | 0g carbs | 18g protein
Price: ~$25–30 for 20 servings

Collagen peptides dissolve completely in hot or cold liquids with no detectable taste or texture. While collagen is not a complete protein (it lacks tryptophan), it's an excellent addition to smoothies, coffee, or soups to boost total protein intake. Collagen also supports skin elasticity and connective tissue during pregnancy. Use it alongside a complete protein source rather than as the sole protein.

Pros: Zero carbs; tasteless and odorless; great for adding to anything; supports skin and connective tissue
Cons: Not a complete protein; doesn't replace a full protein source

7. Drink Wholesome Egg White Protein — Best Minimalist Powder

Nutrition per serving: 150 cal | 5g carbs | 2g sugar | 20g protein
Price: ~$45–55 for 20 servings

Drink Wholesome uses egg white protein (a complete protein with excellent bioavailability) and almost nothing else. The ingredient list is strikingly short: egg whites, cane sugar, cocoa (for chocolate flavor). No artificial sweeteners, no gums, no emulsifiers. It's specifically marketed to people with sensitive digestive systems — relevant in pregnancy.

Pros: Ultra-minimal ingredients; great digestibility; complete protein; no gums or emulsifiers
Cons: Expensive; not vegan; small serving range (20g protein)

8. Nutranelle Prenatal Protein — Best Pregnancy-Specific Powder

Nutrition per serving: 120 cal | 8g carbs | 1g sugar | 20g protein
Price: ~$45–55 for 20 servings

Nutranelle is specifically formulated for pregnancy — it's one of the few protein powders that has been developed with GD management in mind. It contains folate, choline, and other prenatal nutrients alongside the protein, making it a supplement-and-protein-powder combined. The low carb count and lack of artificial sweeteners make it appropriate for GD management.

Pros: Pregnancy-formulated with prenatal nutrients; low sugar; clean ingredients; GD-appropriate
Cons: Expensive; limited availability (primarily online)

GD Smoothie Formula

For a balanced GD smoothie that won't spike blood sugar:

• 1 scoop protein powder (20g+ protein)
• 1/2 cup frozen berries (low-GI fruit)
• 1–2 tbsp nut butter or avocado (healthy fat for satiety)
• 1 cup unsweetened almond or coconut milk
• Optional: 1 cup baby spinach (adds nutrients without carbs)
