Collagen capsules are very popular among dietary supplements. They are sometimes used as a remedy for joint problems and are increasingly taken for cosmetic reasons, such as anti-ageing. With our large collagen capsule test 2022 we want to help you find the best collagen capsules for you. We have compared different collagen capsules and found out the most important information for you.


  • Collagen capsules are a dietary supplement that provides elastic and stable skin, but can also help with joint complaints. The collagen for this is increasingly obtained from parts of cattle, pigs or fish.
  • You can distinguish between hard capsules and soft gel capsules. Soft gel capsules are usually easier to swallow, while collagen hard capsules have a longer shelf life.
  • Unlike other collagen products, collagen capsules are also well suited for on-the-go and for easy and quick intake. This is because collagen capsules are easy to transport and are already pre-dosed.

The Best Collagen Capsules: Our Choices

Buying and evaluation criteria for collagen capsules

When buying collagen capsules, you will come across a large number of different variants. These product variants can be distinguished from each other on the basis of different criteria. In summary, these are:

In the following, we will go into these criteria and thus give you an overview of what you should look for when buying collagen capsules.


How much collagen is actually contained in the individual capsules varies depending on the manufacturer. This is especially important when buying collagen capsules.

You should adjust the concentration of collagen to your required dosage. This is because the amount of collagen you need varies depending on the reason for taking the capsules.

In the shops you can find collagen capsules with a concentration of 1.5 grams and upwards. However, the majority of collagen capsules have a dosage of 5-10 grams of collagen per capsule. Collagen capsules with the correct dosage of collagen make sense as you ensure you take the required amount of collagen. This way you avoid under- and overdosing of collagen.

Amount of capsules per pack

When buying collagen capsules, pay attention to how many capsules are included in the pack. The amount of capsules per pack varies depending on the manufacturer. On average, you should expect 90-120 collagen capsules per pack. You should also pay attention to the dosage. Sometimes it makes more sense to buy a more expensive product with more capsules.

A cheaper product that contains significantly fewer capsules could end up being more expensive. This is because with low-dose collagen capsules you should often take several a day, which is not necessarily the case with high-dose collagen capsules.

Additional ingredients

Most collagen capsules contain additional ingredients. These are intended to make it easier for your body to absorb the collagen or to provide other added value. Below we have listed some of the most common additional ingredients.

  • Hyaluronic acid: This multiple sugar ensures the stability and friction-free movement of the joints. In addition, hyaluronic acid makes connective tissue more elastic and tighter and is moisturising for the skin.
  • Elastin: This fibrous protein ensures that the connective tissue remains elastic. Thus, a combination of elastin and collagen is ideal for creating a good foundation for the skin.
  • Hydrolysate: If the collagen is hydrolysed, free amino acids ensure that collagen is better absorbed by the muscles. Collagen hydrolysate can also provide stronger fingernails and hair, as well as stimulate cartilage formation.

If you particularly like one or more bonus ingredients, you can look out for them when buying your collagen capsule.


When buying collagen capsules, it is important to check whether you tolerate them. The ingredients of collagen capsules vary depending on the manufacturer.

Collagen capsules can contain lactose, gluten or animal ingredients

Often collagen capsules are not gluten or lactose free.

If you have a lactose or gluten intolerance, make sure you buy collagen capsules that are suitable for you. In addition, many collagen capsules consist of animal collagen, sometimes fish and bovine collagen. However, you also have the option of buying collagen capsules made from plants. If you are a vegan or vegetarian, you should take this into account.

Guide: Questions you should ask yourself before buying collagen capsules

Before you buy your collagen capsules, there are a few things you should consider. We will go into these in more detail in the next section.

What is special about collagen capsules and what benefits do they offer?

Collagen is a protein that is also found naturally in your body. You can find collagen in cartilage, tendons and between the joints. Collagen also helps to keep your skin firm.

There are 28 different collagens in the body, which are responsible for different processes. In collagen capsules, three types of these collagens are increasingly used. These can appear as a combination or as a single collagen in a collagen capsule.

In collagen capsules you should distinguish between three types of collagens. Collagen types I and III are responsible for the skin, while type II is found, for example, between the joints.

Collagen capsules offer many advantages. Mainly, collagen capsules are used for joint problems, such as joint pain or as an anti-ging agent. This is because collagen not only supports the stability of the joints and the smooth movement of these, but also keeps the connective tissue stable and elastic.

But collagen capsules also have other benefits, because they strengthen the immune system and provide more energy. In addition, collagen contributes to healthy nails, hair and teeth and relieves intestinal discomfort. Thus, collagen capsules offer a variety of benefits and are very popular among the supplements on the market.

What types of collagen capsules are there?

There are two types of collagen capsules. Below we will show you the advantages and disadvantages of each. This should help you decide which one is right for you.

Collagen soft gel capsules

One of the collagen capsule types is the soft gel capsule. In this type of capsule, the capsule consists of a soft shell that is filled with the active ingredient in the form of a gel.

  • The collagen can be absorbed more quickly by the body
  • The soft capsules are more comfortable to swallow
  • Usually contain no lactose
  • Usually contain emollients such as glycerol or sorbitol
  • Shorter shelf life
  • Can be made of animal gelatine

If this type of collagen capsule is not for you, the following variety of collagen capsules may be more suitable for you.

Collagen hard capsules

The second collagen capsule variant is the hard capsule. Unlike the soft gel capsules, these capsules are hard and usually consist of the compressed collagen powder.

  • Longer shelf life
  • Do not contain plasticisers
  • Usually cheaper
  • More uncomfortable to swallow
  • Often contain lactose
  • The collagen takes longer to be absorbed by the body

In comparison, it becomes clear that both types of collagen capsules have their own advantages and disadvantages. You can decide which one is more suitable for you.

Who are collagen capsules suitable for?

In principle, collagen capsules are suitable for everyone. As this dietary supplement offers many health benefits, it is a popular product on the market. However, depending on the manufacturer, collagen capsules may contain animal ingredients. In addition, they sometimes contain gluten or lactose. Therefore, people who sometimes have the following eating habits or allergies should be attentive when buying collagen capsules:

  • Gluten intolerance: Collagen capsules may contain ingredients such as wheat components.
  • Lactose Int olerance: Collagen capsules may contain lactose ingredients.
  • Vegetarians or vegans: The collagen used could sometimes be derived from fish, beef or pork parts.
  • Cultures or religions with special eating habits: Collagen capsules could contain lactose, meat including pork and alcohol.

If you have such an allergy or eating habit, you can still buy collagen capsules. Just make sure they don’t have any of the ingredients you don’t want or can’t take.

How much do collagen capsules cost?

Compared to other supplements, the cost of collagen capsules is average. However, you will notice that the price range of collagen capsules is very wide. Costs start at around €5 and can go up to over €70 depending on the type of collagen capsule product. You should distinguish between hard and soft gel capsules. We have listed the price ranges in the following table:

Type of capsule Price
Collagen soft gel capsules 10-70 €
Collagen hard capsules about 5-90 €

You will notice that the price of collagen soft gel capsules is usually more expensive. This is because the production of this type of collagen capsule is simply more expensive.

You should also note that depending on the manufacturer, the number of pieces and the recommended daily amount of collagen capsules can vary.

This should help you decide which product is better for you in the long run. If you buy a product with a low number of capsules and a high recommended daily amount of capsules, you will have to buy more of it sooner.

How do I dose collagen capsules correctly?

Since collagen capsules have different collagen concentrations depending on the manufacturer, it makes sense to dose your collagen capsules correctly.
A small dose is useful for cosmetic reasons.

Here, the recommended dosage is about 10 grams per day. If you take 8-10 grams of collagen per day, you will usually get better results than if you take a lower dosage. It is also true that older people in particular need a higher dosage. This is because the body’s production of collagen decreases with age.

However, you should adjust the dosage to suit you. The dosage varies depending on the reason for the intake, which is especially important for joint and cartilage problems. For example, if you are taking collagen for cosmetic reasons, you should take a lower amount, while a high dosage is recommended for severe joint pain. If you are unsure about the required dosage, it is best to discuss this with your doctor.

As a general rule, collagen rarely causes negative side effects and overdosing is almost impossible. However, this does not mean that you should not adjust the dosage to your personal needs.

What side effects can collagen capsules cause?

Taking collagen as a dietary supplement is considered safe because it does not contain any toxic effects. However, in rare cases, the following side effects may occur:

  • Nausea
  • Abdominal pain
  • Dizziness
  • Tiredness
  • Headache

You should therefore only take collagen capsules as a dietary supplement and still eat a healthy diet. If you experience any of these symptoms after taking collagen capsules, you should stop taking them. You may find that you tolerate another type of collagen capsule better.

What are the alternatives to collagen capsules?

If you are looking for an alternative to collagen capsules, you will quickly find one on the market. We have listed some alternatives for you.

Type of collagen Properties
Collagen creams Applied superficially to the skin. It is supposed to have a moisturising effect and make the skin look smoother and plumper. However, this effect is short-lived. This is because the collagen cannot penetrate deep enough into the skin.
Collagen drinking ampoules This is liquid collagen that can be drunk. Like collagen creams, it promises an anti-ageing effect. However, it is controversial whether liquid collagen is digested by the body and reaches the skin cells.
Collagen powder collagen in powder form is suitable for use in liquids and is often used in shakes. However, the powder is also usually more expensive than collagen capsules. In addition, collagen powder is more difficult to transport because it is not ready portioned.

Collagen can also be absorbed through food. However, collagen occurs in nature in much smaller quantities than in food supplements.


With the right dosage, collagen capsules can offer you real benefits, including helping with joint problems and being a rejuvenator for the skin. In addition, compared to other collagen products, they are not only easy to transport, but are also ready-dosed and easy to take.

However, when buying collagen capsules, you should make sure that they do not contain any ingredients that you cannot or do not want to take. Collagen capsules often contain animal ingredients, lactose and gluten. However, you will also find collagen capsules without these ingredients in the shops.
