Collagen: What's worth knowing?

Line chart illustrating collagen decline with age. A pink downward-sloping line shows decreasing collagen levels from age 25 to 75. Marked points at 25, 35, 45, 55, and 75 years indicate progressively lower percentages, with a vertical scale labeled approximately 10%, 20%, 30%, and 50%, emphasizing that collagen loss increases as age increases.

Did you know that collagen production starts to slow down by ~1% every year from the age of 25?


Collagen is naturally produced by the body, but from around the age of 25, collagen production gradually begins to decrease - by approximately 1% each year. During menopause, women may lose collagen even more rapidly. Collagen synthesis can also be negatively affected by external factors such as excessive sugar consumption, smoking, frequent alcohol intake, chronic stress, and prolonged exposure to UV rays.


Let's start with the basics - what is collagen?


Collagen is the body’s main structural protein. It is responsible for skin firmness, joint flexibility, cartilage health, and the strength of hair and nails. As long as the body produces enough collagen, we rarely think about it. However, over time, visible and physical changes begin to appear.


What happens when collagen decreases?


As collagen levels decline, cartilage and skin begin to lose moisture, bones become more fragile, and ligaments and tendons lose elasticity, which may contribute to joint discomfort. Over time, the skin can lose firmness and elasticity, and deeper wrinkles may become more noticeable.

Different tissues need different types of collagen


For example:

  • the skin mainly contains type I and type III collagen
  • cartilage is primarily made up of type II collagen

That is why choosing the right type of collagen is important if you are looking for a specific benefit.

How can you support your body's collagen production?


A balanced and nutrient-rich diet is the foundation. In some cases, collagen supplements may help support collagen synthesis and restoration more effectively. If you are considering adding collagen to your routine, here are a few important things to look for.

 

What should you consider when choosing collagen?


Origin and type

There are several types of collagen available on the market, including marine, bovine, and vegan collagen.

The best choice depends on your diet, allergies, intolerances, and lifestyle.

  • Marine collagen is often chosen to support skin health.
  • Bovine collagen is commonly used for joints and connective tissues.

We offer marine type I and type III collagen sourced from freshwater fish skin. Our collagen is ASC-certified, ensuring sustainable, ethical, and environmentally responsible sourcing.


Form

Collagen supplements are available in liquid, powder, and capsule form. Convenience and absorption matter. Hydrolyzed collagen peptides are considered the most effective form due to their improved absorption. Our collagen comes in powder form and contains marine hydrolyzed collagen peptides. It can easily be mixed into coffee, matcha, juice, smoothies, or water. Unlike many collagen supplements on the market, our collagen is neutral in color, taste, and smell.


Molecular weight

The molecular size of collagen is measured in Daltons (Da). Smaller molecules are generally absorbed more easily by the body. It is recommended to choose collagen with a molecular weight below 2,000 Da. Our collagen has a very low molecular weight - approximately 1,500 Da - which helps support effective absorption.


Ingredients

A high-quality collagen supplement should have a clean and transparent ingredient list.

Beneficial additional ingredients may include:

  • vitamin C,
  • zinc,
  • copper,
  • hyaluronic acid.

It is best to avoid unnecessary fillers, excessive sweeteners, and artificial flavorings. We offer pure collagen without flavorings, sweeteners, or unnecessary additives.


Quality

True quality is supported by facts, not promises.

When choosing collagen, pay attention to:

  • the origin of the raw materials,
  • quality certifications,
  • manufacturing standards,
  • independent testing.

Our collagen:

  • is ASC-certified,
  • complies with HACCP standards,
  • is produced according to GMP practices,
  • is Halal-certified,
  • and is made in Sweden.

The manufacturer is a family-owned company specializing in high-quality health supplements produced using advanced technologies.

 

A clinical study that changed perspectives on collagen

 

This clinical study lasted 12 weeks and followed the highest scientific standards. It was conducted as a double-blind, randomized, placebo-controlled trial - the same type of methodology used to evaluate medications. This means the results are considered reliable, accurate, and clinically significant. The study involved 50 women who consumed either 10 g of marine collagen or a placebo daily over a 12-week period. Each participant’s face was photographed using 3D imaging technology at the beginning of the study and again after 12 weeks. The study found that this marine collagen improved skin elasticity after 6 weeks, with even more noticeable results after 12 weeks.
