Marine collagen, animal collagen, and collagen precursors: what are the differences?

When talking about collagen supplements, it is easy to come across formulations that are very different from one another: marine collagen, collagen of porcine or bovine origin, and products that do not directly contain collagen but rather nutrients and amino acids used by the body for its synthesis.

The difference therefore does not concern only the origin of the main ingredient. Composition, associations with other nutrients, and above all the goal for which the formulation is developed also change.

The Kiros range makes it possible to clearly observe these three strategies through Blue Kollagen and Beauty Collagen, Kollagen, and Hempro Kollagen.

What collagen is and why it is important

Collagen is a structural protein found in connective tissues and is particularly relevant for the skin, joints, tendons, and bones.

With age and in the presence of various environmental and metabolic factors, the balance between collagen production and degradation can change. This is where the interest in formulations that directly provide hydrolyzed collagen or substances involved in its synthesis and protection comes from.

However, there is not just one “collagen supplement”: products that appear similar may follow different nutritional strategies.

Marine collagen: the focus of Blue and Beauty Collagen

Hydrolyzed marine collagen is the basis of Kiros Blue Kollagen and Kiros Beauty Collagen.

Each sachet contains 10 g of hydrolyzed marine collagen, associated with a formulation mainly oriented toward skin well-being.

The collagen component is in fact accompanied by hyaluronic acid, vitamin C from Acerola, silicon, resveratrol, astaxanthin, lycopene, biotin, zinc, and L-cysteine.

The rationale is therefore not to limit the formulation to collagen intake, but to pair it with substances involved in its synthesis, in protection from oxidative stress, and in maintaining skin, hair, and nails.

Blue Kollagen with orange flavor and Beauty Collagen with black cherry or wild berry flavor can therefore be considered the products in the Kiros range most strongly oriented toward the concept of beauty from within, with particular attention to skin elasticity, hydration, and firmness.

Hydrolyzed porcine collagen: the Kiros Kollagen approach

A second strategy is that of Kiros Kollagen, based on hydrolyzed collagen of porcine origin.

In this case as well, the product does not contain collagen alone. The formulation also combines vitamin C, silicon from Equisetum arvense, MSM, vitamin E, and maritime pine extract.

The goal of the formula is broader than that of an exclusively cosmetic product and involves the skin, connective tissues, joints, and support for muscular activity.

This makes Kollagen particularly interesting when attention is not focused only on the appearance of the skin, but also on maintaining tissue structure and joint support.

The difference compared with Beauty Collagen should therefore not be read simply as “marine versus animal”: marine collagen is also naturally of animal origin. The useful comparison is instead between different collagen sources and formulations designed for different goals.

Collagen precursors: a different approach

There is then a third possibility: not to directly provide collagen, but to make available to the body some of the nutrients used in the collagen synthesis processes.

This is the strategy adopted by Hempro Kollagen.

The formulation does not contain animal collagen. Instead, it uses 15 g of hemp proteins, associated with L-proline and L-hydroxyproline, two amino acids present in the collagen structure.

Vitamin C, organic silicon from bamboo, MSM, L-carnitine, vitamin B6, and proanthocyanidins from grape seeds are also added.

Hempro Kollagen therefore represents an alternative designed especially for those who follow a vegetarian or vegan diet and wish to use a formulation that supports endogenous collagen production without taking collagen of animal origin.

It is important, however, not to confuse the two approaches: a product with collagen precursors is not vegetable collagen. Plants do not provide collagen; the formulation instead makes available proteins, amino acids, and nutrients used by the body in the processes related to its synthesis.

Marine, porcine, or precursor collagen: which should you choose?

Rather than looking for an absolutely “better” source, it is useful to start from the goal.

For skin, hydration, and beauty

Beauty Collagen combines marine collagen with a formula particularly rich in components aimed at the skin, including hyaluronic acid, vitamin C, and several natural functional substances.

For skin, connective tissues, and joints

Kollagen uses hydrolyzed porcine collagen and combines it with vitamin C, silicon, MSM, and natural antioxidants, with a broader approach also aimed at joints and connective tissues.

For those who do not want to use animal collagen

Hempro Kollagen instead follows a different path: hemp proteins, precursor amino acids, and nutrients involved in collagen synthesis.

The choice should therefore take into account diet, individual needs, and the goal for which supplementation is being considered.

Vitamin C, silicon, and other nutrients: why they often appear together with collagen

The KIROS formulation philosophy is based on the concept of the “All-in-One Formula”, an approach that integrates selected functional ingredients with complementary characteristics into a single solution, in order to offer complete, targeted, and practical nutritional support, going beyond the traditional model of supplementation based on individual nutrients.

A common element of Kiros formulations is that collagen is not considered an isolated ingredient.

Vitamin C is used in the different formulations for its role in the normal formation of collagen.

Silicon also appears in Beauty Collagen as well as in Kollagen and Hempro Kollagen, through different sources.

The formulations then add specific components according to the goal: hyaluronic acid and antioxidants in Beauty Collagen, MSM and pine extract in Kollagen, precursor amino acids and plant proteins in Hempro.

It is precisely this combination that most distinguishes the three products.

Three formulations, three different approaches

The Kiros family dedicated to collagen can therefore be read through three strategies:

Blue Kollagene and Beauty Collagen → marine collagen + beauty and antioxidants

Kollagen → porcine collagen + connective tissues and joints

Hempro Kollagen → plant proteins + collagen synthesis precursors

They are therefore not simply three versions of the same product.

They are formulations developed from different needs and that make it possible to choose between direct intake of marine collagen, collagen of another animal origin, or a strategy based on plant proteins and precursors.

Important note: food supplements do not replace a balanced diet. The choice of the most suitable formulation must take into account individual nutritional needs and, when necessary, the indications of the doctor or healthcare professional.
