What is marine collagen?

Marine collagen is collagen extracted from marine sources. It is produced primarily from the skins and scales of fish such as cod, tilapia and salmon. Marine collagen jet very similar in structure to that found in your bodyand. In its hydrolysed form, it is one of the most effective collagen supplements.

Are marine collagen, marine collagen and fish collagen the same substance?

Yes, marine collagen is, when translated from English, marine collagen. And in our native language, fish collagen and marine collagen are synonyms. So marine collagen, marine collagen and fish collagen are exactly the same substance.

The most powerful fish collagens contain vitamin C in their formulation. It makes the preparation better absorbed by the body. Moreover, vitamin C stimulates collagen synthesis in the body.

How does marine collagen work?

Marine collagen is distinguished by its health-promoting properties. Find out what effects you can count on by regularly supplementing with marine collagen.

Promoting skin health. Collagen is the most important component of the dermis - responsible for up to 90% of its mass. Therefore, marine collagen supplementation can make the skin more supple, firmer and hydratedand.
Promotes joint health. Collagen is involved in the production of synovial fluid, which prevents joint friction. As you get older, you start to lack this synovia and your joints start to crunch. Supplementation can replenish collagen in your joints and restore their youthfulnessand.
Hair benefits. The basic component of hair is keratin, for the production of which amino acids such as lysine are essential. You will supply most of the valuable amino acids to the body with collagenand.
Reduces nail brittleness. Like hair, nails are made up of keratin. Collagen = lots of amino acids, and lots of amino acids = lots of keratinand.
Increases immunity. Collagen has a positive effect on immunity, not least because it supports gut health. And as many as 70-80% of immune cells are found in the gutand.

Which collagen is better - marine or bovine?

The best collagen in terms of origin is marine collagen. Studies suggest that it absorbs up to 50% better than bovine collagen, or bovine collagenand. This allows you to benefit from its properties more quickly and effectively.

After how long will marine collagen take effect?

Marine collagen can support the health of skin, hair, nails and joints. Studies suggest that regular supplementation with collagen will produce results after 8-24 weeksand. This is quite a discrepancy, but every body is different and will respond differently to collagen supplements.

FAQ

What is marine collagen for?

Marine collagen can be used to improve the appearance of skin, hair and nails, as well as for bone health. To take advantage of its benefits, use supplements with sea collagen at a dose of 2.5-15 grams.

How long can you take fish collagen?

Take fish collagen for approximately 8-24 weeks to achieve the best results. This cyclical dosage helps the body absorb collagen and stimulates the body's natural production of its own protein. As for the length of supplementation, there is no limit, use collagen continuously.

Does collagen have side effects?

Collagen is safe to consume, however, it can cause several side effects. Some of these include allergic reactions, stomach pains and stomach upset or bloating. Choose collagen products from reputable sources, as poor quality can affect your health.

What fruit and vegetables is collagen found in?

Collagen is an animal protein, not a plant protein. Therefore, fruits and vegetables do not contain collagen, but they do support collagen synthesis in the body. Consume fruits rich in vitamins, such as citrus, kiwi or strawberries, and vegetables such as peppers, broccoli or spinach.

Does collagen rejuvenate?

Yes, collagen can aid the rejuvenation process. Use its properties to improve the elasticity of skin, reduce wrinkles and hydrate the complexion. The effects of collagen can also contribute to increased bone density and muscle strength and volume.

Systematically take collagen supplements or consume collagen-rich foods, such as bone broths and jellies. To maximise the effects, also ensure a healthy diet, hydration and regular physical activity.

Is it safe to take collagen?

Taking collagen is usually safe. Choose proven supplements from reputable manufacturers. Start with lower doses, observing your body's reactions, and then increase to the recommended serving, usually around 5-15g per day.

If you experience side effects, such as allergic reactions or digestive problems, reduce the dose or consult your doctor. For special groups, such as pregnant or lactating women, or people with autoimmune diseases, seek medical advice before starting supplementation.

What are the symptoms of collagen deficiency?

The first symptoms of collagen deficiency occur as early as 25-30 years of age. The most common of these include:

wrinkles and loss of elasticity of skin,
dryness of the skin and deterioration of its appearance,
weakening of hair and nails,
pain and stiffness of joints.
difficulty in regenerating connective tissue (tendons, ligaments),
loss of muscle mass and strength,

If collagen deficiency is suspected, introduce products rich in this protein or supplements into your diet, and maintain a healthy lifestyle.
