What's actually in Kollo's marine collagen formula?
Collagen supplements often talk about "vitamins in collagen" — but collagen itself is a protein made of amino acids, not vitamins. What varies between collagen products is what other ingredients are formulated alongside the marine collagen peptides. This article walks through exactly what's in each Kollo product, and what those ingredients actually do — using the proper regulatory-compliant descriptions.
Vitamin C — 80mg (100% NRV)
Ascorbic Acid
In all three Kollo formatsVitamin C is the one ingredient shared across all Kollo formats. It's included alongside the marine collagen because vitamin C is genuinely essential for the body's own collagen synthesis — the enzymes that produce collagen from dietary amino acids require vitamin C as a cofactor.
EU-authorised health claims for vitamin C include:
- Contributes to normal collagen formation for the normal function of blood vessels, bones, cartilage, gums, skin, and teeth
- Contributes to the normal function of the immune system
- Contributes to normal energy-yielding metabolism
- Contributes to the reduction of tiredness and fatigue
- Contributes to the protection of cells from oxidative stress
- Contributes to normal psychological function
- Increases iron absorption (particularly from plant sources)
The 80mg per Kollo serving delivers 100% of your daily NRV (Nutrient Reference Value used for EU labelling).
Vitamin B1 (Thiamine) — 1.1mg (100% NRV)
Thiamine Hydrochloride
In Kollo Liquid onlyVitamin B1 (thiamine) is an essential B vitamin found in wholegrains, pork, legumes, and fortified foods. It plays specific metabolic and nervous system roles.
EU-authorised health claims for vitamin B1 include:
- Contributes to normal energy-yielding metabolism
- Contributes to normal functioning of the nervous system
- Contributes to normal psychological function
- Contributes to normal function of the heart
Vitamin B5 (Pantothenic Acid) — 6mg (100% NRV)
Calcium Pantothenate
In Kollo Liquid onlyVitamin B5 (pantothenic acid) is a B vitamin found widely across foods — meat, eggs, mushrooms, avocados, and wholegrains. Its name comes from the Greek "pantos" meaning "from all sides" because it's so widely distributed in the food supply.
EU-authorised health claims for vitamin B5 include:
- Contributes to normal energy-yielding metabolism
- Contributes to normal mental performance
- Contributes to normal synthesis and metabolism of steroid hormones, vitamin D, and some neurotransmitters
- Contributes to the reduction of tiredness and fatigue
Note: You may see B5 marketed elsewhere for acne. Some research on high-dose B5 (10g+ per day) and acne exists but isn't established medicine. Kollo's B5 dose is 6mg (100% NRV) — a normal daily nutritional amount, not a therapeutic dose. Kollo is not a treatment for acne. If you're dealing with persistent acne, please see your GP or dermatologist for proper assessment.
Vitamin B6 (Pyridoxine) — 1.4mg (100% NRV)
Pyridoxine Hydrochloride
In Kollo Liquid onlyVitamin B6 (pyridoxine) is an essential vitamin — meaning your body cannot produce it and must obtain it from diet or supplements. It's found in poultry, fish, potatoes, bananas, chickpeas, and fortified cereals.
EU-authorised health claims for vitamin B6 include:
- Contributes to normal protein and glycogen metabolism
- Contributes to normal red blood cell formation
- Contributes to the normal function of the immune system
- Contributes to normal functioning of the nervous system
- Contributes to normal psychological function
- Contributes to the reduction of tiredness and fatigue
- Contributes to normal homocysteine metabolism
- Contributes to the regulation of hormonal activity
Vitamin B12 — 2.5µg (100% NRV)
Methylcobalamin
In Kollo Liquid onlyVitamin B12 is found predominantly in animal-source foods — meat, fish, eggs, and dairy. Vegans and vegetarians are at higher risk of B12 deficiency and often require dedicated supplementation or fortified foods (see note below). Kollo uses methylcobalamin, one of the naturally occurring forms of B12.
EU-authorised health claims for vitamin B12 include:
- Contributes to normal energy-yielding metabolism
- Contributes to normal function of the nervous system
- Contributes to normal homocysteine metabolism
- Contributes to normal red blood cell formation
- Contributes to the normal function of the immune system
- Contributes to the reduction of tiredness and fatigue
- Contributes to normal psychological function
- Has a role in the process of cell division
L-Lysine — 178mg
Essential Amino Acid
In Kollo Liquid onlyL-lysine isn't a vitamin — it's an essential amino acid, meaning your body can't produce it and must obtain it from dietary protein. It's found naturally in meat, fish, eggs, dairy, and legumes. Kollo Liquid includes 178mg per serving as one of the amino acids the body uses across various protein synthesis processes.
Regulatory status: L-lysine does not currently have specific EU-authorised health claims. It's included in the Kollo liquid formula as a beneficial essential amino acid rather than for a specific claimed health outcome.
What about the marine collagen itself?
All three Kollo products deliver 10,000mg of Naticol® 4000 hydrolysed marine collagen peptides per serving. Marine collagen is a protein made up of 18+ amino acids, predominantly glycine, proline, and hydroxyproline. Marine collagen supplementation has strong clinical evidence for supporting skin outcomes (elasticity, hydration, appearance of fine lines) over 8-12 weeks of consistent daily use, and emerging evidence for joint comfort at 12+ weeks.

Frequently Asked Questions
Does marine collagen naturally contain vitamins?
No. Collagen itself is a protein — it contains amino acids (predominantly glycine, proline, and hydroxyproline), not vitamins. When collagen products mention "added vitamins," they're referring to nutrients formulated alongside the marine collagen peptides in the same product.
Why does Kollo add vitamin C to the marine collagen?
Because vitamin C is genuinely essential for your body's own collagen synthesis. The enzymes that produce collagen from dietary amino acids require vitamin C as a cofactor. Kollo includes 80mg (100% NRV) of vitamin C in all three product formats — the powder formats keep it minimalist with just marine collagen and vitamin C.
Which Kollo product has the most nutrients in it?
Kollo Liquid Marine Collagen has the most added ingredients: alongside the 10,000mg marine collagen and 80mg vitamin C, it also contains 100% NRV of B1, B5, B6, and B12, plus 178mg of l-lysine. The powder formats (sachets and pouch) keep the formula minimalist with just marine collagen + vitamin C — better for people who prefer the cleanest possible ingredient list or already take other supplements separately.
Can Kollo treat vitamin deficiencies?
No. Kollo is a marine collagen supplement that includes nutritional amounts of certain vitamins in its liquid formula — not therapeutic doses for treating diagnosed deficiencies. If you have a diagnosed vitamin deficiency (particularly B12), please follow your GP's guidance on appropriate supplementation. Diagnosed deficiencies often need targeted supplementation or medical treatment.
Does the powder version have B vitamins too?
No. Kollo Powder (both sachet and pouch formats) contains only marine collagen and vitamin C — no B vitamins. If you want the full cofactor stack (B1, B5, B6, B12, and l-lysine) alongside your marine collagen in a single product, Kollo Liquid is the format that includes these.
Do the vitamins in Kollo really do all those things?
The EU-authorised health claims listed above describe what these vitamins do when you have adequate intake — they support normal metabolic and body functions. They're not treatments for symptoms or conditions in the absence of deficiency. If you're broadly meeting your daily needs through diet, additional supplementation typically maintains normal function rather than producing dramatic effects.
Should I take B vitamins if I'm not deficient?
B vitamins are water-soluble — excess is generally excreted rather than stored, and they have a strong safety profile at nutritional doses. If your diet includes animal products or fortified foods regularly, you're likely meeting most of your B vitamin needs already. Vegans, vegetarians, older adults, and people on certain medications may benefit from additional supplementation — please speak to your GP.
