Marine collagen: how to choose a supplement to suit your routine

Marine collagen appeals to adults who want to incorporate a food supplement into their beauty and wellbeing routine. Powder, capsules, tablets or liquid sticks: there is no shortage of choice. Yet with differences in dosage, composition and format, it is not always easy to know which option to choose.

Before placing your order, three common pitfalls are worth bearing in mind:

  • Confusing the quantity of product with the quantity of collagen: a 180 g sachet does not necessarily contain 180 g of peptides. Check the daily serving and the quantity of hydrolysed collagen peptides provided per serving.
  • Relying solely on the claims “types 1, 2 and 3”: these indications should be accompanied by a breakdown in figures. A product may list several types without specifying the quantity of each one.
  • Overlooking allergens and additional ingredients: marine collagen generally comes from fish. It is therefore unsuitable for people with fish or seafood allergies. Flavourings, sweeteners, preservatives and added vitamins also deserve careful attention when reading the label.

Criteria to check before buying

1. The source and collagen profile

Marine collagen is made from raw materials of fish origin. Supplements containing types I and III are often associated with routines focused on the skin, hair and nails, according to the manufacturer’s presentation. Type II, meanwhile, is generally highlighted in formulas intended for cartilage and joints.

A marine collagen formula containing types 1, 2 and 3 may suit people who want to target several goals with a single product. However, check the quantity of each type. For example, some Nutri&Co products state 6,000 mg per serving, including 5,600 mg of types I and III and 400 mg of type II.

The term hydrolysed means that the raw material has been broken down into peptides. This is a useful formulation criterion to compare, but on its own it does not guarantee effectiveness or visible results.

2. The actual dosage and daily serving

Compare products on a like-for-like basis: the quantity of collagen per day, the number of servings and the length of use.

Here are a few examples from the selection:

  • a Nutri&Co powder provides 6,000 mg per 6.1 to 7.5 g dose, depending on the flavour;
  • the cocoa version provides 8,000 mg per 10 g serving;
  • WeightWorld tablets provide 1,800 mg per three tablets;
  • WeightWorld Pure Marine Collagen capsules provide 1,170 mg per two capsules;
  • Swedish Collagen sticks provide 12,500 mg per 25 ml stick.

These figures alone are not enough to establish a ranking. You should also consider the format, additional ingredients, daily cost and your own consumption habits.

3. Additional ingredients and precautions

Vitamin C is often added to collagen supplements. Under the authorised nutritional claim in the European Union, it contributes to normal collagen formation, which is needed for the normal function of the skin, bones, cartilage, teeth, gums and blood vessels.

Hyaluronic acid, zinc, biotin and vitamin D may also be included in the formula. Their value depends on your dietary needs and your routine as a whole. Avoid combining several supplements containing the same vitamins, so that you do not exceed the recommended intake.

Finally, remember to check the following information:

  • fish or seafood allergens;
  • the presence of milk, as found in some chewable tablets;
  • sweeteners, sugars and flavourings;
  • recommended daily dose;
  • minimum age and precautions during pregnancy, breastfeeding or medical treatment.

Frequently asked questions about marine collagen

How can you incorporate a collagen supplement into your routine?

Follow the dose stated on the packaging, ideally at a set time each day. The powder can be mixed with a cold or room-temperature drink, according to the manufacturer’s instructions. Liquid sticks can be taken directly after opening. Like any food supplement, it does not replace a varied diet or a balanced lifestyle.

How long does a box of marine collagen last?

It depends on the number of servings. A box of 30 sticks will generally last 30 days, while 120 capsules may cover one to two months depending on the daily dose. Once opened, store the product in a dry place away from heat and light, and carefully reseal the sachet or bottle.

Is vegan collagen marine collagen?

No. Marine collagen is of animal origin and generally comes from fish. Products presented as vegan collagen do not contain marine collagen. Instead, they combine vitamins, minerals or selected plant extracts to support nutritional intake and normal collagen formation. People with fish allergies should avoid marine products and check the full labelling carefully.
