Capsule Size
20mm x 7mm (2-piece) capsule

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.

Our capsules consist of types I and III. Type I is the most abundant collagen of the human body. It is present in scar tissue, the end product when tissue heals by repair. Type III, which helps with healing wounds, is often found alongside Type I.

A guaranteed high quality Amino Acid profile

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

Service rating: Great service easy to purchase and well packaged. Site easy to navigate.
Product: My hair nails need 8bit of help due to illness so I thought it would be a good idea to give it a try,and it's working my nails are already getting stronger and less brittle and my hair has already thickened a little
Delivery and improved recyclable packaging
Quick delivery, like the new paper packaging, a very thoughtful touch.
Service rating: We are years long customers of Just Vitamins. Why? The top quality, very good prices and speed on dispatch. What else?
Product: I DO notice a difference in my hair and nails and am on my second pouch of capsules. I can't say if I feel my skin is positively affected yet because I am using various topical serums, but the capsules can only be good from the inside out.
Ecellent service and quick delivery.
Great thank you
Service rating: Quality products, well packed and delivered promptly.
Product: I take collagen to supplement my own supply as production decreases with age. I like to think it helps my joints and tissues retain strength and elasticity.
Service rating: Good, Easy to use, Arrived quickly

Service rating: Rapid delivery of an excellent product.
Product: Excellent product. Delivered quickly
Service rating: The last 1 - 2 years I have been buying vitamins that made my indigestion worse, as I already have some indigestion problems.
The Just Vitamins not only did not cause me indigestion, have improved my stomach, really worked on me better than I expected.Yes I will buy them again. It will take a bit of time to reorder as I bought a lot of them, but I will. The good thing is that I don't have to go through customs to get them, they come directly to me.
Hopefully will stay the same when BREXIT happens.
The other thing that I find so good is that the tablets test is good.
They don't give you any difficulty taking them, the main thing for me is that my indigestion and stomach got better.
Product: The little bit I tried it found improvement to my skin and strength,
so based on the period I tried it I can give it still excellent
Service rating: prompt reliable service and box goes thru letter box;
Product: good for the skin as you age
Service rating: I live in Spain and would prefer my order to be sent by courier so that I can track it and because it seems more secure. Having said that, so far after numerous orders the Post Office hasn't let me down once. I like Just Vitamins because their pricing structure is clear and transparent. With the Penny sales and buy one get one half price of HB I always feel I'm being ripped off because I don't know the true price of anything. Well done, Just Vitamins.
Product: I use this instead of protein for the gym and it seems to be a perfect replacement.
Service rating: Quick
Product: It seemed to work from the very next day. My gym workouts improved as well as my sleep. Very happy
Service rating: Always a good and easy service. Products are also good and priced reasonably.
Product: Too early to tell if they are having any effect. Easy to swallow. You can also break and add to yoghurt or smoothies.
Very prompt delivery. Good reliable service.
detailed, prompt, very clear website
Highly recommend. Great product and fast delivery!!!
Too early to say what the tablets are like ,but the service was excellent
Quick and efficient
Service rating: I love just vitamins, they are a good price and quick delivery, and my favorite bit is they are in a seal pack so can be posted. I've used them 3 times so far and will continue to.
Product: I love the collagen tablets, they make my skin soft and wrinkle free, I take 2 a day so the 90 tablet pack lasts a good while.

The service was quick, but unfortunately I can't say anything about the vitamins because I have not taken enough to see results. Thank you.
