Why People Take Collagen
Collagen is naturally found throughout the body, including the skin, bones, muscles and connective tissues. As natural collagen production gradually declines with age, many people choose to include collagen as part of their daily routine.
Our premium hydrolysed collagen dissolves easily into water, coffee, smoothies and many other drinks, making it simple to incorporate into everyday life.
Why Our Collagen?
Every batch is produced using carefully selected raw materials and independently tested to ensure consistent quality from one purchase to the next.

Frequently Asked Questions
Why choose Kollajoin collagen?
Kollajoin was founded by people with more than 25 years of nutraceutical industry experience. We specialise in two carefully selected hydrolysed collagen powders rather than offering an extensive range of unrelated supplements.
Both products are independently tested, manufactured in a GMP-certified UK facility and made without added artificial preservatives, colourants, hormones or flavourings. Each 300g recyclable pouch provides 30 convenient 10g servings.
How do I take collagen?
Mix one 10g serving, approximately one tablespoon, into 250ml of water, coffee, juice, a smoothie or another preferred drink. The unflavoured powder is designed to dissolve easily without overpowering the drink.
Do not exceed the recommended maximum daily intake of 20g. Food supplements should always be taken as part of a varied, balanced diet and healthy lifestyle.
Where is Kollajoin collagen manufactured?
Every Kollajoin product is manufactured in a GMP-certified UK facility and independently tested to help ensure consistent quality, purity and performance.
Our Fish Collagen is produced from carefully selected, sustainably sourced fish, while our Bovine Collagen is produced from pasture-raised, grass-fed cattle.
What is hydrolysed collagen?
Hydrolysed collagen has been broken down into smaller chains of amino acids called collagen peptides. This makes the powder easier to dissolve in liquids and easier for the body to digest than intact collagen.
Both Kollajoin products use hydrolysed collagen peptides and mix easily into water, coffee, juice, smoothies and other drinks.
Can I take fish and bovine collagen together?
Yes, fish and bovine collagen can be included within the same routine. However, taking both is not essential: many people simply choose the source and collagen profile that best suits their preferences.
Always follow the serving instructions on each pack and do not exceed the stated maximum daily intake. Kollajoin Fish Collagen is not recommended for anyone with a fish or shellfish allergy or intolerance.
Which collagen is best for joints and connective tissues?
Bovine Collagen naturally contains Types I and III collagen and is commonly chosen as an all-round collagen supplement by people looking to support joints, muscles and connective tissues as part of a healthy lifestyle.
Individual needs vary, so anyone managing a medical condition or taking medication should seek advice from a qualified healthcare professional before starting a supplement.
Which collagen is best for skin, hair and nails?
Fish Collagen is naturally rich in Type I collagen, the most abundant collagen found in human skin. For this reason, it is a popular choice for people looking to support their daily skincare routine, as well as healthy hair and nails.
Food supplements should be used alongside a varied, balanced diet and healthy lifestyle rather than as a substitute for either.
What's the difference between fish and bovine collagen?
The main difference is their natural collagen profile and source. Fish Collagen is naturally rich in Type I collagen and is produced from sustainably sourced fish. Bovine Collagen contains Types I and III collagen and is produced from grass-fed cattle.
Both Kollajoin products contain premium hydrolysed collagen peptides. The best choice depends on the collagen types you prefer, the source you are comfortable with and any dietary or allergen requirements.
