Collagen is a key building block of the human body and is used in the formation and support of bones, cartilage, ligaments, tendons and other key strength-giving components. Collagen contains many amino acids - these are the building-blocks of proteins, and have a central role in biochemistry and nutrition.

Crucial to the maintenance of skin tissue and elasticity

Your body combines collagen with other proteins to give collagen its elastic properties - so it is crucial in the formation, development and maintenance of skin tissue. In fact it is the deterioration of the collagen's elasticity that causes the skin to sag in places and cause wrinkling as we age.

The collagen protein used in supplements such as this one, is broken down into smaller chains of amino acids via a process called hydrolysation. This hydrolysation process makes it easier for the body to absorb the collagen, and therefore ensures that less of it is wasted once consumed.

Premium quality hydrolysed marine collagen for optimal ingestion

Just Vitamins Collagen capsules are manufactured using only the finest hydrolysed, marine-sourced collagen, as opposed to the cheaper and less desirable bovine-sourced collagen. Our collagen is encapsulated in a cellulose-based capsule shell, so will be perfectly acceptable to fish-eating vegetarians ('pescatarians'), although Just Vitamins doesn't class this as a truly vegetarian supplement. The collagen in our supplement is produced solely from fish skin and is guaranteed shark-free. As with all our fish-based supplements, the raw material is from a sustainably managed source.

Our capsules contain Type I collagen, the most abundant form in the human body. It is present in scar tissue, the end product when tissue heals by repair. 

A guaranteed high quality Amino Acid profile

Our collagen also has an guaranteed Amino Acid profile, listed under the Nutritional Information tab.

Review Details
Immediate delivery - competitive prices and good flat packed vitamins.
Service rating: Always buy their products and seem to do the job! Very reasonable in cost as well and great when you get a discount code! Thanks.
Product: Works well and happy with product.
The service was quick did not wait too long for delivery, like the packaging, I have old bottles I transfer my vitamins in to. I noticed hair growth more on one eyebrow and feel more energetic since taking these vitimins I purchased K2, Vitimins C with Zinc collagen, and Vitimins E
Skin much improved, hair shinier
Service rating: I’ve returned to Just Vitamins as I was impressed with their range of vitamins, and with such a speedy delivery
Product: As ladies go through the menopause one thing they lose us collagen in their body, this supplement gives back collagen to my body
This review is based on service as I can't evaluate the efficacy of the products at this stage. Ordering was easy, delivery was fast and I love the packaging. It allowed me to send vitamins abroad at a reasonable cost as well as ensure that the delivery would be received whether home or not.
Service rating: It’s not often that you get free delivery on all purchases that are competitively priced. Just vitamins also give good advice and excellent product description and information on all their products.
Product: I have only given 3 stars because I have only been taking these for a few weeks to help with the signs of ageing! I have not yet noticed anything but I will carry on until the pack is empty and re-evaluate
Reasonable price and good service
Very good service. Easy to use website and excellent products.
Service rating: Fast, effective service
Product: I love this product, my skin, hair and joints have really benefited from taking it
Service rating: Service brilliant. Easy to order and delivery was quick.
Product: Unfortunately after 15 days I had such bad pain and tenderness in my lower colon so had to stop them. I've since learnt that they can create intestinal problems so plenty of water should be had while taking them. I was taking them to hopefully help with joints and skin elasticity
good product and came quickly
Excellent service. Arrived promptly.
Good on price, free delivery in the UK. Fast service. Vitamins appear good quality. I have used Just Vitamins for years and always been happy
Excellent product, price and service. Will buy again!
Service rating: Excellent service as always and quality tablets.
Product: These really help my joints, have been taking them for years now.
Service rating: I ordered from Switzerland and I received my vitamins just in few days. Fast and reliable. Large choice on the website which is well done.
Product: My skin is rehydrated from inside and looks much better.
very good service and prices, good delivery
Excellent from ordering to delivery. Good range of supplements. Only thing is with the 50+ multivitamins and minerals is they do contain Iron. As to much iron can be bad for some people, Correct me if i am wrong but extra iron in supplement form should only be taken with advice from a GP. The NHS advise that adult men should not need to supplement with iron as you can get enough i.e.7.0 to 8.0 mg from your diet. Therefore a 50+ multivitamin and mineral without iron would be a good thing for those 50 plus who don't need iron
Fast delivery and high quality products.
I am always very satisfied about the excellent service of Just Vitamins. Thank you ;-)
I have used JustVitamins for several years now and have always been happy with the speedy service and reasonable prices. I highly recommend them.

Product: Best value and as I am in my seventies I need all the help I can get.
Service rating: Fast and efficient, minimum packaging.
Product: So far so good! I take them when I remember and cannot say if they have fulfilled my expectations yet.
Service rating: Just Vitamins are quick to send. We are very happy with the quality and service. I have noticed the positive effects of the Marine Collagen within only a few weeks.
Product: I really like this product. I notice an improvement in skin and hair after only a few weeks and I am 70 years young. I will continue to order!
