How to choose a quality collagen supplement – ​​a practical guide

Collagen is one of the most important proteins in the human body. It is responsible for the elasticity and strength of the skin, joints, bones, hair and nails. After the age of 25, its natural production begins to decrease, leading to the appearance of wrinkles, joint pain and other signs of aging. In this context, collagen supplements are becoming extremely popular. But how to choose a quality collagen supplement? This guide will help you make an informed and effective choice.


What type of collagen does the supplement contain?

There are at least 28 types of collagen, but the most important for health and beauty are types I, II and III:

  • Type I – The most common type, responsible for the strength of skin, bones and tendons.

  • Type II – Main component of articular cartilage. Suitable for mobility problems.

  • Type III – Found in the skin, blood vessels and organs. Improves elasticity and tissue structure.

Choose a supplement that combines type I and III if you are looking for effects on your skin and appearance. If your main goal is joints – type II is a priority.


What is the source of collagen?

The origin of collagen directly affects its quality, digestibility and safety:

  • Marine collagen (from fish) – The most digestible and bioactive collagen. Rich in Type I.

  • Bovine Collagen (from beef bones and skin) – Contains Type I and III. Suitable for skin, hair, nails.

  • Chicken collagen – Main source of type II, good for joints and cartilage.

  • Pork collagen – Less common, but with good properties similar to bovine.

Search for products from sustainable and verified sources, without antibiotics, hormones or heavy metals.


Is collagen hydrolyzed?

Hydrolyzed collagen (or collagen peptides) means that the protein has been pre-broken down into smaller molecules (peptides), which makes it easier for the body to absorb it.

Look for the phrases “hydrolyzed collagen”, “collagen peptides” or “verisol®. They ensure that collagen reaches where it is needed – skin, joints, bones.


Are there additional ingredients that improve effectiveness?

Collagen does not work in isolation. Its effectiveness is increased in the presence of certain supporting ingredients:

  • Vitamin C – Necessary for the synthesis of new collagen. Increases absorption.

  • Hyaluronic acid – Improves skin hydration and together with collagen makes the skin smoother.

  • Zinc, copper, biotin – Support the structure of skin and hair.

  • Glucosamine and Chondroitin – Suitable supplements to type II collagen for joint problems.

Combined formulas often give faster and more visible results.


What form does the supplement come in?

Collagen comes in different forms: powder, capsules, tablets, ampoules or chewables. Each type has its own advantages:

  • Powder – The most versatile form, often tasteless and odorless. Suitable for smoothies, coffee, soups.

  • Capsules and tablets – Convenient to take, but often contain a smaller amount of active ingredient.

  • Liquid collagen – Faster to digest, often with a pleasant taste.

  • Ampoules and Shots – Concentrated dose, practical for daily use.

Choose a form that fits your rhythm and habits so you don’t miss a dose.


Has the product been clinically tested?

The most reliable supplements have clinically proven results that demonstrate the effectiveness of the formula used. Look for mention of:

  • Branded ingredients such as Verisol®, Peptan®, Fortigel®

  • Links to scientific studies

  • Results after 4, 8 or 12 weeks of use

Avoid products of questionable origin or without real data on effectiveness.


Are there any unwanted additives in the composition?

Look carefully at the label to avoid fillers, artificial colors, sweeteners, allergens and GMO ingredients. The best products are:

  • No sugar

  • Gluten Free

  • No lactose

  • No synthetic additives

The purer the composition, the better your body will accept it.


Is the product certified and transparent?

Make sure the collagen supplement has the necessary quality and safety certificates, such as:

  • GMP (Good Manufacturing Practice)

  • ISO 22000

  • Certificates of organic or sustainable origin

  • Label transparency and access to laboratory tests

Avoid products without a clearly stated origin or those that avoid specific data.


How long should it be taken?

Collagen does not work instantly. For optimal results:

  • Minimum 8-12 weeks of continuous use

  • Long-term use is appropriate, especially for people over 30.

  • It is recommended to take daily, without major interruptions

It is best combined with a healthy lifestyle, hydration and a balanced diet.
