When you start a GLP-1 (like Mounjaro, Wegovy or Ozempic) journey, food changes. Your appetite drops, meals shrink, and suddenly protein matters more than ever. This Berry Protein Shake became my go-to because it checks every box: high protein, light on the stomach, and full of collagen for the things that tend to suffer when we eat less, hair, skin, nails, and energy.

When I first began treatment, I quickly learned that less food can also mean less nutrition. That’s why I started building meals that work harder for me. A small, nutrient-dense shake like this can cover what a plateful of food used to.

It’s easy to digest, keeps me full for hours, and helps prevent the fatigue and hair loss that so many GLP-1 users face. And I can drink it in a few hours, if I get full too fast.

Why This Shake Works

Protein powerhouse. With Greek yogurt, protein powder, and collagen, you get over 50 grams of protein in one drink that you can finish in a few hours if you get full fast.
Collagen support. Helps rebuild what your body sometimes neglects during weight loss, hair, skin, and nails.
Fiber fix. Flaxseed and psyllium husk keep digestion moving and help prevent that dreaded GLP-1 constipation.
Quick recovery. Perfect after a workout or as a small, balanced breakfast.
Flexible texture. Use water for a lighter shake, or milk for a creamier one.

Ingredients Needed

Collage of ingredients for the protein shake.

Greek yogurt: Adds creaminess, probiotics, and extra protein when you can’t eat much.
Vanilla or strawberry protein powder: Your main protein source; pick clean, low-sugar brands.
Collagen powder: Two scoops boost skin, hair, and joint health.
Frozen mixed berries: Natural sweetness and vitamin C.
Flaxseed: Omega-3s, fiber, and healthy fat.
Psyllium husk powder: Supports digestion and thickens the shake slightly.
Water, ice, or milk: Adjust for texture. Milk or plant milk adds creaminess and calcium. If you add milk, skip the yogurt.

How To Make This Shake

Step 1. Add Greek yogurt, protein powder, collagen, berries, flaxseed, and psyllium to a blender.
Step2. Pour in about 1 cup cold water or milk and 1 cup of ice.
Step 3. Blend on high for 45–60 seconds until smooth.
Step 4. Check the blender markings and add more liquid as needed to reach about 24 oz total volume.
Step 5. Blend again briefly and drink immediately.

Expert Tips

Use ground flaxseed so your body uses it fully.
Stick to 1 teaspoon psyllium for a light shake or 2 teaspoons for extra fiber, but drink it fast, it thickens quickly.
Keep the shake simple. Veggies don’t belong here, the flavor balance will suffer.
Swap half the water for milk or fortified plant milk if you need extra calcium or calories.

Why Collagen Matters Here

When food volume drops, collagen intake often plummets. That’s when nails get brittle and hair starts shedding, a common complaint during GLP-1 therapy. Adding collagen powder daily made a visible difference for me within a month.

Finally, this shake is simple, but it hits all the essentials: protein, collagen, fiber, and hydration. It’s not about dieting, it’s about staying nourished when your appetite is smaller.

Equipment

1 Blender

Ingredients

½ cup Greek yogurt
1 scoop whey protein powder vanilla or strawberry
2 scoops collagen powder or the serving size suggested on the product
½ cup mixed berries frozen
1 tablespoon flaxseed
1 teaspoon psyllium husk powder
Water and ice to fill a 24 oz cup

Instructions

Add Greek yogurt, protein powder, collagen, frozen berries, flaxseed, and psyllium to the blender.
Pour in about 1 cup (240 ml) cold water and 1 cup ice.
Blend on high for 45–60 seconds until smooth.
Check the blender markings and add more water as needed to reach about 24 oz total.
Blend again briefly to mix.
Pour into a glass and serve immediately.

Notes

Vanilla or strawberry protein works best.
Fresh berries work; add extra ice to chill and thicken.
Swap part of the water with milk for a creamier shake.
Serve right after blending while it’s cold and airy.
If you must save it, refrigerate up to 12 hours and shake before drinking — psyllium thickens as it sits.
