Collagen – the key to a strong interior

What is collagen and why is everyone talking about it?

Have you ever wondered why some people radiate energy, have clear, supple skin, or seem to have a stomach that always stays calm? The answer often lies within us in the form of collagen—the body’s most abundant protein. From a nutritional perspective, collagen isn’t just a trendy supplement, it’s a crucial component for everything from your gut health to your ability to unwind after a long day. It’s time to find out what collagen really does for your health—and why it’s so hot right now.

Strong intestines and stomach – the foundation for well-being

The role of collagen in intestinal and stomach health

Collagen is naturally found in the body's connective tissue, and not least in your gastrointestinal tract. The intestinal walls are lined with a layer of collagen that supports their function and barrier. A strong intestinal wall protects against inflammation and contributes to good digestion. This means, among other things, that nutrient absorption is improved and the risk of leaky gut is reduced - two factors of enormous importance to our general well-being.

• Collagen supports healing of the intestinal mucosa
• May help reduce stomach problems such as IBS and sensitive stomach
• Promotes balanced absorption of nutrients

Practical tip: Try adding collagen powder to your morning smoothie or your cup of coffee to support your stomach's well-being, especially if you often have a sensitive stomach.

The immune system: a robust defense – built from within

Why a functioning immune system needs collagen

Did you know that almost 70% of the immune system is located in the gut? Collagen plays an important role here. When the intestinal wall is strong and intact, the body can effectively protect itself against foreign substances. The result? You become less susceptible to viruses and inflammation. As a nutritionist, I often see that a weak immune system can be due to poor gut health – and collagen is an important key there.

• Helps prevent harmful substances from leaking into the bloodstream
• Supports the body's natural defenses against pathogens
• Provides optimal conditions for intestinal flora balance

Tip: A daily collagen supplement can be valuable for those of you who often get sick or feel tired and worn out.

Skin and hair – outer beauty that reflects inner nourishment

The Science Behind Collagen for Skin and Hair Health

The skin's elasticity, firmness and ability to retain moisture are largely controlled by collagen. Unfortunately, the body's own collagen production decreases from the age of 25–30. The result is dry, less elastic skin and thinner hair. By adding collagen via dietary supplements, we can support the body's natural processes and give the skin the building blocks it needs to maintain its youthful appearance.

• Tightens tired and sagging skin
• Reduces visibility of fine lines and wrinkles
• Strengthens hair follicles and provides thicker hair

Practical tip: Combine collagen powder with vitamin C-rich foods, such as oranges or kiwi – vitamin C increases the body's ability to absorb and produce collagen.

Joint health: support for mobility and activity

Collagen for healthy joints and an active lifestyle

Stiff, aching joints are often a natural consequence of aging – but many people don’t know that this is largely due to decreased collagen levels. Joint cartilage is made up mostly of collagen, and when it breaks down, the risk of joint problems increases. Research shows that collagen supplementation can reduce joint pain, support cartilage regeneration and improve mobility, regardless of activity level.

• Contributes to joint flexibility and function
• Supports recovery after training or injury
• Reduces the risk of wear and tear injuries and joint stiffness

Tip: For best results – take your collagen with a source of protein in direct connection with physical activity.

Stable weight and balance – collagen as support in everyday life

How collagen contributes to weight control and satiety

Maintaining a healthy weight is largely about balancing hunger and satiety hormones. Collagen has a unique ability to help increase satiety and thereby reduce snacking – something that is especially valuable for those trying to lose or maintain a steady weight without compromising on nutrition.

• Collagen is rich in protein and provides an increased feeling of satiety.
• Supports muscle mass, which increases metabolism
• Can reduce sugar cravings and irregular eating

Practical tip: Stir collagen powder into yogurt or chia pudding for a nutritious, protein-rich breakfast.

Combining collagen with keto – the optimal duo

Why collagen is perfect for the ketogenic diet

Many people on a keto diet risk missing out on essential amino acids when carbohydrates and certain proteins are eliminated. Collagen is an excellent source of protein, rich in glycine, proline, and hydroxyproline, and does not affect blood sugar. Collagen also supports ketone body levels, while protecting muscle and connective tissue during weight loss.

• The science behind collagen shows that it keeps you full without disrupting ketosis
• Helps regulate blood sugar and reduce sugar cravings
• Supports muscle and connective tissue during weight loss

Tip: Dissolve a spoonful of collagen in your morning coffee (bulletproof) for an easy keto-friendly start to the day.

Sleep and recovery – nutrition for calm and rest

The role of collagen for deeper relaxation

The body's ability to relax, sleep well and recover is strongly linked to specific amino acids, most notably glycine – which is abundant in collagen. Research has shown that glycine promotes deep sleep and supports the body's own relaxation system, both physical and mental recovery.

• Relieves stress and anxiety by calming the nervous system
• Promotes natural sleep cycles and provides deeper rest
• Improves recovery after exercise and everyday stress

Practical tip: Take collagen as an evening drink together with, for example, oat milk to support a calmer evening and better sleep.

Everyday use – simple and effective

Including collagen in your diet doesn't have to be complicated. The powder is tasteless and dissolves easily in both cold and hot beverages, making it easy to integrate into your regular routine. Here are some suggestions for easy ways to get collagen in your diet every day:

• Stir into juice, coffee or tea
• Mix in smoothie or overnight oats
• Add to stews, soups and sauces
• Stir into yogurt or chia pudding
• Create your own nutritious bars or pastries

Regardless of your lifestyle, there's an easy way to increase your intake of this important protein. Check out our collagen products here to find a variant that suits you and your everyday life.
