Easy on the gut:naturally low lactose, minimal ingredients, no gut drama

Daily versatility:shakes, smoothies, oats or baking - one scoop, once a day

Description
What's inside & why it works

Rebuild is for people who want to keep training hard without their protein working against them. 27g of grass-fed whey feeds muscle now; 5g of collagen peptides supports the joints, tendons and skin holding it all together.

Naturally low lactose and made with minimal ingredients, it mixes smooth and sits light - no bloating, no gut drama.

Use it after training, or any time of day you need protein that pulls its weight.

How To Use
Dosage & timing

Mix 1 scoop with 250-300ml of cold water or milk. Vary the liquid to your preferred taste and thickness.

Best practices:

  • Shake with cold water for a lighter everyday serve, or milk for a creamier one
  • Blend into smoothies when you want a thicker, more filling shake
  • Stir into oats or use in baking for a practical protein boost
  • Keep it consistent on training and non-training days - the collagen benefits build with daily use

Use as part of a balanced diet. Protein needs vary by body size, training and total food intake.

Benefits
What you'll feel

Taking Rebuild daily, you'll notice:

  • Sits light: smooth and creamy, with none of the heaviness or bloat standard whey can cause
  • Recovery you can feel: 27g of grass-fed protein and 7g BCAAs anchoring your post-training nutrition
  • Long-run support: 5g collagen peptides for skin, joints and tendons - benefits that build over weeks, not days
  • An easy routine: works in shakes, smoothies, oats and baking
  • No compromise: tastes like a treat, with a label you can actually read

Individual results vary. Use as directed and pair with consistent nutrition, movement, hydration and sleep.

WHO IT'S FOR

If any of these are you

icon

YOU TRAIN HARD

High-volume phases where the joints take as much of a beating as the muscles.

icon

YOU'RE IN IT FOR THE LONG RUN

Training isn't a phase. You want to recover well, stay strong, and still be turning up in twenty years.

icon

STANDARD WHEY DOESN'T SIT RIGHT

Every tub so far has left you bloated or heavy. Naturally low lactose and minimal ingredients change that.

icon

YOU WANT MORE THAN MUSCLE

Skin, joints and tendons matter as much as the mirror - and collagen works on the parts training stresses most.

FAQs

Frequently asked questions

The WPI is pure whey isolate - 27.8g protein, less than 1g fat and carbs, 99.9% lactose-free. It's the leanest option. Rebuild combines whey isolate and concentrate with 5g of hydrolysed collagen peptides to support joints, tendons, skin and recovery alongside muscle. Choose WPI for maximum protein with minimum calories. Choose Rebuild if you want muscle and structural support in one serve.

Rebuild contains hydrolysed bovine collagen peptides which support joint, tendon and ligament health over time. It's not a quick fix, but consistent use alongside training helps reinforce the connective tissue that takes a beating during heavy or high-volume sessions. Most customers notice a difference within 4-6 weeks.

Rebuild is naturally low in lactose and made with minimal ingredients - no artificial sweeteners and no fillers, which are common causes of bloating in standard protein powders. It's not as lean as our WPI (which is 99.9% lactose-free), but most customers report no digestive issues.

Active people generally aim for around 1.2 to 2.2 grams of protein per kilogram of body weight per day, depending on training load and goals. The specific amount varies with your fitness goals, activity level and overall food intake - and it's best spread evenly across the day.

Thick, creamy and naturally sweetened with organic stevia. No artificial aftertaste. Available in Dutch Chocolate and Salted Caramel, with more flavours returning soon. Not sure? Grab a single-serve sample before committing.

You can, but most people won't need to. Rebuild already delivers 5g of hydrolysed collagen per serve alongside 27g of whey protein. That's a solid daily dose of collagen for joint and connective tissue support without buying two separate products.

Yes. Rebuild supports lean muscle retention during a calorie deficit while the collagen helps maintain skin elasticity and joint health as body composition changes. The added fullness from the thicker texture also helps with appetite control between meals.
