Why it matters

Skin, hair and nails renew continuously — collagen is among their structural components.

Type I and III collagen form the bulk of skin structure — including the tissue in which hair and nails are anchored.

My skin and hair are in better shape. My hair feels stronger and has more vitality. My skin looks fresher and feels firmer. For me, it took a good six weeks.

    Easy to take

    The collagen capsules are pleasantly small and easy to swallow. At a recommended dose of 6 capsules a day, one pack lasts a month. For anyone wanting to use collagen as a supplement, this product is a good choice: taking it is straightforward, and the capsules have no unpleasant aftertaste. All in all a good product that I can recommend!

    Capsules instead of powder

    I wanted to try the capsules, as it is often annoying to take collagen as a powder when travelling. The recommended daily dose is 4–6 capsules, which does make sense so that a decent amount actually gets into the body. The collagen comes from pigs, which you might perceive as bad, but the opposite is the case: pig collagen closely resembles human collagen, so absorption is good. I take the capsules in the morning on an empty stomach and have no problems at all. Particularly good: the collagen has no additives, just pure collagen. All in all top!

    Outstanding! Here is my assessment in detail: Packaging – brown apothecary glass, high-quality, no cheap plastic packaging or the like. The label is well designed and informative. Ingredients – patented peptides. 100% collagen, from Germany, no additives; I find that convincing. Use and effect – daily use has paid off. My skin is noticeably and visibly fresher. My hair is fuller and stronger too. Verdict – thumbs up!

    Kollagen Institut is my new favourite brand: fast delivery, a high-quality product in apothecary glass. First effect after a few weeks. Top top top!!!

    I notice a difference

    The capsules are odourless and without any aftertaste. The effect is of course always hard to describe. I have now been taking the capsules for six months, and my skin is doing better and better. It is a sort of gradual process, but in the right direction!

    First impression

    First impression: high-quality apothecary glass. Good capsule size – not too large (hard to swallow), not too small (otherwise no effect). Label legible and informative. Very positive on the ingredients: only collagen, no other additives, no fillers or the like. The collagen comes from Germany, which makes me confident – not imported from somewhere in Asia and then bottled. It all makes a good impression. Even if there should be no effects on my skin in a few weeks (we shall see, I have only just started!), the nutritional values are good for my body: plenty of protein, no sugar, no unnecessary calories.

Questions about collagen for skin, hair and nails

How collagen peptides support skin, hair and nails, how to take the powder, and when changes may become noticeable.

Why collagen for skin, hair and nails?

Skin, hair, and nails are made up largely of collagen. In particular, the skin contains many collagen fibers — especially type I collagen. These fibers form a stable network that gives skin structure, firmness, and elasticity.

As we age, our natural collagen levels decline. Bioactive collagen peptides provide targeted signals at the cellular level and can help support the skin’s elasticity and firmness, as well as the strength of hair and nails.

What are fibroblasts, and why are they important?

Fibroblasts are specialized skin cells responsible for producing collagen, elastin, and other connective tissue components. They help skin maintain its structure, firmness, and resilience.

As we age, fibroblast activity slows down. Bioactive collagen peptides can help support these cells and promote the skin’s natural renewal processes — for a smoother, more refined-looking complexion.

How do I take the collagen?

Our collagen fits easily and flexibly into your daily routine.

Powder:
Stir the recommended daily amount into water, coffee, tea, or a smoothie. It is tasteless and dissolves well in both cold and warm drinks.

Capsules:
Take the recommended daily dose with plenty of liquid - ideally with a meal.

When will I see results?

Visible changes typically appear after 4–8 weeks of daily use. Lasting effects build over the course of months.

Why exactly 90 days?

Collagen building is a step-by-step process. 90 days give the body enough time for real structural changes — not just surface-level ones.

Why bioactive peptides — and not just collagen?

These are bioactive collagen peptides — a specific peptide fraction studied clinically for targeted effects. Generic collagen has an undefined peptide structure and is usually not clinically studied.

Is long-term use safe?

Yes. The peptides used have been studied in long-term trials over several years.

Taken daily. Benefits build over time.
