Why Choose Grass-Fed Collagen?

Our grass-fed collagen ensures the highest quality, free from additives and sourced sustainably, so you can trust every sachet.

The Bioactive Collagen Peptides (BCPs) in our Complete Collagen are designed for easy absorption and effective use by the body.

The way collagen is absorbed isn’t about whether it comes in a drink, gel, powder, or capsule. What matters is that it reaches the collagen-producing cells with the right molecular size to stimulate collagen production.

BCPs have a special single-helix (drill-like) structure that allows them to pass through the gut intact. This means they survive digestion and reach the skin and body’s collagen-producing cells.

The BCPs in Complete Collagen are clinically proven to boost collagen in the skin, tendons, and ligaments:

• VERISOL® B: Stimulates fibroblasts in the skin to support collagen production.
• TENDOFORTE®: Supports tendons and ligaments by activating specific cells (tenocytes and ligamentocytes).

These BCPs are the only collagen peptides scientifically proven to have this stimulating effect.

With its tangy citrus flavour, Complete Collagen tastes like an orange ice lolly.

Types of Collagen & Their Benefits:

  • Essential for joint flexibility, cushioning, and lubrication.
  • Ideal for active individuals and those experiencing joint discomfort or osteoarthritis.
  • Best Source: Bovine Collagen (FORTIGEL® Bioactive Peptides) – specifically designed to support cartilage health (found in our Osteo+ product).

Your unique body, lifestyle and individual circumstances will determine this but the clinical results indicate that:

4-8 weeks

• 15% increase in skin elasticity
• 65% increase in pro-collagen
• 20.1% decrease in wrinkle volume
• 18% increase in elastin

12 weeks

• 60% of patients returned to running faster

14 weeks 

• Improvement in hair thickness

24 weeks

• Improvement in nail growth and strength
• Improvement in the appearance of cellulite (by 11%)

Our Complete Collagen sachets contain Type I and Type III collagen.

• Type I collagen makes up about 90% of the body’s total collagen. It provides strength and support to the skin, connective tissues, bones, and teeth.
• Type III collagen is mainly found in the skin, muscles, organs, intestines, and blood vessels.

Although different types of collagen exist throughout the body, their classification isn’t important when it comes to nutrition.

For example, Type I and Type II collagen are about 85% identical in their protein structure. This small difference does not affect how they work once broken down into Bioactive Collagen Peptides, which stimulate collagen production in the body.

Our collagen is bovine-based, meaning it comes from cows.

Bovine collagen provides Type I and Type III collagen, the same types that are most abundant in the human body. Unlike marine collagen, bovine collagen is structurally more similar to human collagen because we are genetically closer to mammals than fish. This similarity makes it easier for the body to absorb and use, improving its bioavailability.

It is therefore not suitable for vegetarians.
