What is Marine Collagen Multi?

Marine Collagen Multi is a multi-nutrient supplement that combines hydrolysed bovine collagen peptides with glucosamine hydrochloride, along with a comprehensive vitamin and mineral premix. The formula is designed to support the structural integrity of connective tissues, including skin, joints, and bones. Collagen is the most abundant protein in the human body, providing structure and elasticity to skin, tendons, ligaments, and bones. As we age, natural collagen production declines, which is why many people turn to collagen supplements to help maintain skin hydration, joint comfort, and overall connective tissue health. This product also includes biotin, vitamin C, and zinc—nutrients that play specific roles in skin, hair, and nail health.

Marine Collagen Multi ingredients

Each 13.8g serving of Marine Collagen Multi powder provides the following ingredients as listed on the label:

• Connective Tissue Blend: Spray Dried Bovine Collagen, Glucosamine Hydrochloride (from crustaceans)
• Fibruline® (Chicory Dietary Fibre)
• Acidity Regulator: Citric Acid
• Vitamin and Mineral Premix: Magnesium Sulphate, Tri-Calcium Phosphate, Calcium Carbonate, Vitamin C (Ascorbic Acid), Maltodextrin, Vitamin E (Dl-Alpha Tocopherol), Nicotinamide, Ferrous Fumarate, Vitamin B5 (Calcium D Pantothenate), Vitamin A (Retinyl Acetate), Vitamin B12 (Cyanocobalamin), Vitamin B2 (Riboflavin 5-phosphate), Vitamin D3 (Cholcalciferol), Vitamin B6 (Pyridoxine Hydrochloride), Thiamine, Zinc Sulphate Monohydrate, Folic Acid (Folacin), Biotin, Potassium Iodide
• Flavouring, Natural Colour (Beta Carotene), Sweetener: Steviol glycosides

This blend provides a broad range of nutrients, including collagen peptides for structural support, glucosamine for joint health, and a full spectrum of vitamins and minerals to support overall wellbeing.

How the formula was designed

The Marine Collagen Multi formula was designed to provide a comprehensive, all-in-one approach to connective tissue support. The inclusion of bovine collagen peptides provides the amino acids glycine, proline, and hydroxyproline, which are the building blocks of collagen synthesis. The addition of glucosamine hydrochloride, a compound naturally found in cartilage, is included to support joint health and mobility. The vitamin and mineral premix covers key nutrients that work synergistically with collagen: vitamin C contributes to normal collagen formation and normal skin function; zinc supports normal skin, hair, and nails; and biotin contributes to normal hair and skin health. The formula also includes B vitamins to support energy metabolism, and vitamin D3 for normal bone health. The powder format allows for easy mixing and flexible dosing, making it a convenient choice for daily use.

The science — what's well-supported

The science behind Marine Collagen Multi is grounded in well-established health claims for its individual nutrients. According to the EU Register of Nutrition and Health Claims, the following authorised claims apply to the ingredients in this product:

• Vitamin C contributes to normal collagen formation for the normal function of skin, bones, and blood vessels (EFSA Journal 2010;8(10):1815).
• Zinc contributes to normal skin, hair, and nails (EFSA Journal 2014;12(11):3848).
• Biotin contributes to normal hair and skin health (EFSA Journal 2014;12(7):3756).
• Vitamin D3 contributes to normal absorption of calcium and phosphorus and normal bone health (EFSA Journal 2016;14(10):4581).
• B vitamins (B2, B5, B6, B12, niacin) contribute to normal energy-yielding metabolism (EFSA Journal 2010;8(10):1814).

Regarding collagen peptides specifically, a meta-analysis published in the Journal of Cosmetic Dermatology (2019;18(5):1285-1292) found that oral collagen supplements may improve skin hydration, elasticity, and density. However, the European Food Safety Authority (EFSA) has not authorised a specific health claim for collagen as of 2025. Similarly, glucosamine has been studied for joint health, but EFSA has not approved a claim for its role in joint structure or function. Therefore, these ingredients are included based on traditional use and emerging evidence, not authorised health claims.

How to take it

For best results, mix one scoop (13.8g) of Marine Collagen Multi powder with 200ml of water or juice. Use a shaker or blender to ensure thorough mixing. The powder may settle during storage, so weighing the serving on a kitchen scale is recommended for the most accurate measure. Take one serving daily, preferably with a meal to support absorption of fat-soluble vitamins (A, D, E). Consistency is key—daily use over several weeks is likely needed to notice benefits for skin and joint comfort.

Storage

Store Marine Collagen Multi in a cool, dry place, out of direct sunlight and away from heat sources. Keep the pot tightly sealed after each use to prevent moisture absorption. Do not use if the seal is damaged. The best before date is printed on the base of the pot. As a powdered product, it should be kept out of reach of children.

Allergen and dietary information

Marine Collagen Multi contains glucosamine hydrochloride sourced from crustaceans (shellfish). It is not suitable for vegetarians or vegans due to the bovine collagen and shellfish-derived glucosamine. The product is Halal approved. For a full list of allergens, refer to the ingredients in bold on the label. The product is manufactured in a facility that handles other allergens, but cross-contamination is managed through strict protocols.

Who should be cautious

If you are pregnant, breastfeeding, or have a medical condition, consult your healthcare professional before use. Individuals with shellfish allergies should avoid this product due to the glucosamine hydrochloride derived from crustaceans. Those on blood-thinning medication (e.g., warfarin) should speak to their doctor before taking vitamin K-containing supplements—though this product does not contain vitamin K, it does contain vitamin E, which may interact with anticoagulants in high doses. As with any supplement, do not exceed the recommended daily dose.

What pairs well with Marine Collagen Multi

For a more targeted approach, consider combining Marine Collagen Multi with other Vitadefence products that complement its benefits:

• Collagen Multi – A similar formula but with a different collagen source (bovine) and a slightly different vitamin profile, ideal for those who prefer a non-marine option.
• Marine Collagen Multi – The same product, available in a different format or flavour variant.
• MSM + Vitamin C – MSM (methylsulfonylmethane) is a sulphur compound that supports joint and connective tissue health, while vitamin C enhances collagen synthesis.
