About Complete Collagen
About Complete Collagen
Collagen is more than a beauty buzzword. It’s the most abundant protein in the human body, responsible for healthy skin, hair, nails, joints, and more.
From your mid-20s, collagen levels naturally begin to decline. And you might notice more fine lines, duller skin, thinner hair, weaker nails, or creakier joints. A high-quality collagen supplement can help you bounce back.
But most products use animal collagen (which doesn’t match human collagen) or ineffective vegan boosters.
Our Complete Plant-based Collagen gives you a pure, potent dose of collagen, without the compromise. Powered by VeCollal®, a biomimetic collagen formulation that replicates the amino acid composition of human Type I collagen using plant-based amino acids produced via controlled fermentation.
- It's the world’s first plant-based formula to perfectly mimic human collagen.
- Clinically proven results in as little as two weeks
- Enriched with vitamin C, biotin, bamboo, ginseng, and matcha for extra support
- 100% plant-based and ocean-friendly
Benefits
Benefits
- Visibly smoother, firmer skin: boosts skin collagen density, elasticity, and hydration to reduce the appearance of wrinkles.
- A more radiant, even complexion: improves smoothness, reduces redness and shrinks pore size for balanced, glowing skin.
- Stronger, healthier hair and nails: Biotin, Bamboo Extract, and VeCollal® support keratin and collagen production, the essential proteins for strong nails and thicker hair.
- Joint comfort and flexibility: increased collagen production fortifies cartilage, tendons, and ligaments for better mobility.
- Energy and vitality: powerful antioxidants (Vitamin E, Matcha, Beta Carotene) help protect cells against oxidative stress, while Vitamin C contributes to energy metabolism.
- Gut health and overall wellness: over time, collagen helps strengthen connective tissues and the gut lining, supporting resilience inside and out.
How To Use
How To Use
Take one scoop daily with 500 ml of water, juice, or your favourite drink.
Choose Mango to mix directly into water for a zingy boost, or Unflavoured to stir into your favourite smoothies or meals. Remember, consistent use delivers the clearest results.
The only thing we suggest avoiding is mixing Complete Collagen with coffee. Caffeine can inhibit nutrient absorption, so it’s best to leave at least 30 minutes between your supplements and your coffee.
Taste
Taste
- Mango: Transform your skin, hair and nails with a tropical twist. Simply mix with water for a light, juicy and refreshing drink that’s delicious enough on its own.
- Unflavoured: Packs the same punch, without the taste. Neutral and versatile, it’s perfect for blending into smoothies or breakfast bowls.
Whichever you choose, it’s all smooth sipping from here. No clumping, no odour, no funny aftertaste. Just flavours that fit your routine, and a formula that delivers.

Clinical Studies
VeCollal® is the plant-based, proven formula for looking and feeling your best. In clinical trials, participants saw visible results within weeks:
- After 2 weeks, wrinkles reduced by 14.6% and collagen density increased by 4.8%, with further boosts in hydration and elasticity.
- After 4 weeks, wrinkles reduced by 22.4%, skin hydration rose by 7.4%, and smoothness improved by 15.8%. Redness also reduced by 16.3%.
- By 8 weeks, wrinkles were reduced by 32.9%, skin texture improved by 13.1%, and pore size shrank by 5.6%.
And with daily use, the benefits keep building: fewer fine lines, firmer skin, stronger hair and nails, better joint support, and lasting wellness.

Collagen keeps your skin firm, smooth, and resilient, but from your mid-twenties, it naturally declines by about 1.5% each year. By 60, you could lose up to 80% of your collagen density*
That’s why we created Complete Collagen, powered by VeCollal®, clinically proven to boost skin collagen density by 13.9% in just 4 weeks.
The result? Firmer, smoother, more radiant skin.

Collagen is one of your body’s key structural proteins, making up about 30% of your total protein mass. You can think of it as the “glue” that holds everything together, providing your skin, hair, nails, bones, and joints with strength, support, and elasticity. That’s why as collagen naturally declines with age, we start to see wrinkles, duller skin, weaker nails, thinner hair, and stiffer joints.
Our other supplements - like Omega-3, Vitamin D3, Sea Moss and Marine Magnesium are essential single-ingredient products. They’re designed to give your body daily support, but they’re much simpler by nature.
Collagen Complete is different. It’s part of our Complete range: a carefully blended formula with multiple active ingredients working together for skin, hair and nails. At the heart of it is VeCollal® - the world’s first plant-based collagen identical to human collagen, and a very costly ingredient to produce.
We keep everything else stripped back: minimal packaging, no unnecessary extras. That way, what you’re really paying for is the highest-quality formula we can create - not waste, not fluff.
Yes. Collagen Complete is designed to sit alongside the rest of our range. Many of our customers combine it with Omega-3, Vitamin D3 or Sea Moss for all-round support. Each product has its own role, and they complement rather than compete with each other.
Collagen isn’t an “ingredient” you can get from your food. It’s a protein your body naturally produces from amino acids in your diet (either from animal products like meat, fish and dairy, or plant-based sources like soya and quinoa). But from your mid-20s, collagen production slows down, falling by about 1% each year. A high-quality supplement can top up your collagen levels, keeping skin, hair, nails and joints healthy.
Apart from being unethical and less sustainable to produce, animal collagen is fundamentally different from human collagen. It’s often missing essential amino acids, like l-tryptophan, which make it an incomplete protein.
VeCollal® is a biomimetic collagen. It’s designed to replicate the exact structure and amino acid profile of human Type 1 collagen, so your body can recognise it and use it much more effectively.
VeCollal® is clinically proven to transform your skin, but there are plenty more benefits above and below the surface.
Hair and nails: Alongside VeCollal®, our formula contains Biotin and Bamboo Extract (silica) to support keratin and collagen production - key proteins responsible for strong, healthy hair and resilient nails.
Muscles and joints: When you boost your collagen density, the difference is more than skin deep. Collagen also supports the strength and resilience of cartilage, tendons, and ligaments, which may help joint comfort and flexibility.
Energy and vitality: Vitamin C contributes to energy metabolism, while a blend of antioxidants (Vitamin E, Matcha, Beta Carotene) helps protect cells against oxidative stress to replenish and revitalise.
Like any supplement, your results will gradually fade if you stop taking it. Collagen levels naturally decline with age, so consistency is key to see and feel the long-term benefits.
