Grass-Fed Confidence
Rebuild starts with whey from pasture-raised, grass-fed cows and pairs it with hydrolysed bovine collagen peptides. Cold-processed to preserve the natural protein structure your body absorbs more efficiently. No heat damage. No chemical processing. Two premium protein sources in one clean formula you can trust every scoop.
More than just a protein powder
Why Collagen Matters
Strength increases faster than your joints can adapt. That's why injuries happen. Hydrolysed collagen peptides support the structures that hold you together while whey builds the muscle on top.
Benefits:
- Reinforces joints, tendons and ligaments under load
- Supports skin elasticity and gut health
- Absorbs fast — hydrolysed peptides are broken down for rapid delivery
- Works alongside whey, not instead of it
5g of collagen per serve. No need for a separate supplement.

Whey Protein FAQs
Get the answers you need about our whey protein products, including details on ingredients, benefits, usage, and more. Our FAQs cover everything from protein sources to mixing tips, helping you make the most of your supplement.
What's the difference between Rebuild and the WPI?
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.
Will this help with joint pain?
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.
Will this protein make me bloated?
Rebuild is naturally low in lactose and made without gums, thickeners or artificial sweeteners. These are the main causes of bloating in most protein powders. It's not as lean as our WPI (which is 99.9% lactose-free), but most customers report no digestive issues.
How much protein powder should I take daily?
The recommended daily intake of protein for active individuals and athletes can range from 0.5 to 0.8 grams per pound of body weight. However, the specific amount can vary based on your fitness goals, activity level, and overall caloric intake. It's generally advisable to spread your protein intake evenly throughout the day.
How does it taste?
Thick, creamy and naturally sweetened with organic stevia. No artificial aftertaste. Available in Vanilla, Dutch Chocolate, Salted Caramel, Banana and Strawberry. Not sure? Grab a single-serve sample before committing.
Can I take this alongside a separate collagen supplement?
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.
Is this suitable for weight loss or cutting phases?
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.
Does protein powder go off or expire?
Yes, protein powder does have a shelf life and can go off or expire. Here are some key points about the shelf life of protein powder:
- Most protein powders have a "best by" or expiration date printed on the container, typically ranging from 1-2 years after the manufacturing date.
- Over time, protein powder can start to degrade, lose its potency, and develop an unpleasant taste or odor.
- Exposure to heat, moisture, and air can accelerate the degradation process, so it's important to store protein powder in a cool, dry place with the lid tightly sealed.
- Once opened, it's best to consume protein powder within 6-12 months for optimal freshness and quality.
- Signs that a protein powder has gone bad include a rancid smell, clumping, discoloration, or an off-putting taste.
