GUT-SKIN FIRST (GS1) Internal Foundation is a highly concentrated oral formula developed according to the latest scientific findings to support the gut-skin axis.
It helps to protect and maintain a healthy gut flora - the basis for a balanced complexion.
The unique formula combines three types of collagen with over 400 different proteins, 17 amino acids, hyaluronic acid and elastin. These ingredients provide valuable building blocks that support skin elasticity, moisture balance and vitality from the inside out.
Other components such as lycopene, Italian grape seed extract, glutathione and vitamin C complement the effect. Vitamin C contributes to normal collagen formation for normal skin function and supports cell protection against oxidative stress.
All ingredients work synergistically with the gut-skin axis to supply the body with important micronutrients and create the basis for healthy, resilient skin from within.
DOUBLE DOSE WITH 3 TYPES OF COLLAGEN

Marine collagen
Marine collagen peptides type I are rich in proteins and contain 17 amino acids, including hydroxyproline, proline and glycine - important building blocks of the body's connective tissue.
With 2,500 mg of marine collagen, GS1 provides a concentrated dose of high-quality collagen peptides. Marine collagen sources are considered to be particularly bioavailable and resource-friendly - with a significantly lower carbon footprint compared to bovine collagen.

Egg membrane collagen
Egg membrane collagen type I, V & X
Natural source of around 400 proteins and biomolecules - including collagen, hyaluronic acid and elastin - as well as glucosamine and chondroitin sulphate.
What is the gut-skin axis?
The GUT-HAUT axis ( Gut-Skin Axis) describes the complex interaction between the gut and skin in the body. It has a significant influence on immune health and the appearance of the skin.
At its core, the Gut-Skin Axis is the center for immune defense and skin renewal - the inner production site for healthy skin, so to speak. It is the source of life, the origin of everything.
The GUT-HAUT axis therefore forms the "inner foundation" for radiant, resilient and healthy skin.
Why is this so important?
Every day we lose and damage around 35 million cells - caused by factors such as pathogens, infections, inflammation, ageing, pollution, UV damage, poor diet and, in some cases, professional treatments.
Even with a good skincare routine, without a healthy GUT-HAUT axis, the skin cannot perform to its full potential, especially during times when the body is under greater stress.
A healthy gut-skin axis ensures that your body, hair and skin are continuously supplied with toxin-free cellular building blocks.
It is also home to a bacterial ecosystem that acts like small factories and produces so-called postbiotics. Once absorbed, these bioactive substances support the production of healthy skin cells, improve the skin barrier, promote hair growth and reduce harmful inflammation.
How does GUT-SKIN FIRST work?
The GUT-SKIN FIRST (GS1) formulation combines a double dose of three types of collagen:
Marine collagen and eggshell membrane collagen in types I, V and X. These provide over 400 different proteins, 17 amino acids, hyaluronic acid, elastin, glucosamine and chondroitin sulphate - all essential micronutrients that support your GUT-SKIN axis. This allows your body to replace the millions of cells it needs every day.
GS1 also helps your body produce higher quality cells by ensuring the gut is not inflamed, stressed or deficient in these essential micronutrients.
GS1 activates fibroblasts, boosts hyaluronic acid production, promotes cell regeneration and hydration, and improves the skin's ability to fight off infection and inflammation.
The formulation also contains four important supporting ingredients:
Lycopene, Italian grape seed extract, glutathione and vitamin C. This combination has a strong anti-inflammatory effect and supports the gastrointestinal tract, promotes detoxification, strengthens the immune system and protects the liver. It also helps to regulate melanin production, reduces UV-induced stress and inflammation and supports collagen absorption and the maintenance of existing collagen.
A healthy GUT-SKIN axis is key to building the internal foundation for healthy, functioning skin, hair and joints.
As GS1 is highly concentrated, just two servings per day (5 g) are enough to provide optimal nourishment for your skin, hair and body.
