Research is key when choosing a supplement.

At withinUs Natural Health, we are proud to provide only premium grade products to our customers.

We stand behind our products 100% and we are fully aware that not all marine collagen are created equal, and it is important to ask questions. We can help educate our customers by providing them information as well as provide them with scientific research and independent clinical trials on our marine collagen to back up our statements. We also ensure our product is evaluated and analyzed with stringent testing. We fully believe that knowledge is power, and objective information should be the deciding factor when choosing what goes into your body.




withinUs TruMarine™ Collagen is the highest grade of collagen available in North America. How many people can say that about their product?

Our collagen is Non-GMO Project verified and comes from wild, sustainably caught fish. The fish used for our product are caught for human consumption and the scales are used for TruMarine™ Collagen. Sustainable seafood is caught in a way that doesn’t harm the environment or other species, and are conscious of the issue of overfishing.  

withinUs TruMarine™ Collagen is broken down by a natural enzymatic process (no heat, acid, or chemicals), leaving 100% ultra-pure marine collagen. We ensure that our product is carefully tested and screened for all metals, including mercury. 




In comparison to other collagen sources, TruMarine™ Collagen (derived solely from fish scales) has fewer impurities. Other collagen sources contain more impurities which ultimately affects the quality as well as the taste and smell. withinUs TruMarine Collagen is virtually tasteless and odourless, and is in a pure powder form - making it easy to add into hot or cold liquids without affecting the flavour. Many other collagen products are lower quality which affects the taste, which is the reason flavors, sweeteners or colors are added. 




The hydrolyzation process that withinUs TruMarine™ Collagen undergoes is an important process that ensures maximum absorption, allowing your body to utilize as much of the product as possible.

Enzymatic hydrolization is a process that utilizes enzymes, rather than harsh acids and heat, to break down the scales. This process breaks the product down to a low molecular weight - 3000-5000 Daltons - which makes it highly bioavailable. High bioavailability is extremely important for a supplement as it is an indication of how well the product is absorbed by the body.

Other popular consumable sources of collagen, including - bone broth, cartilage and fish skin - have a much higher molecular weight, making it difficult for the body to break down and absorb. These alternative products have a lower bioavailability than TruMarine™ Collagen.  




Ultra-pure withinUs TruMarine™ Collagen is characterized by its unique amino acid composition, and offers a high concentration of specific amino acids with special nutri-functional properties that are beneficial to health and beauty. Proline, Hydroxyproline and Glycine are the amino acids necessary for collagen production in the body. This specific combination of amino acids cannot be found in other foods. 




Collagen promotes joint health by helping to repair joint matrix degeneration and improves long-term joint comfort and mobility.

In comparison to other supplements recommended for joint pain, which temporarily relieves pain, withinUs TruMarine™ Collagen actually helps improve overall joint health. Collagen works from within the joints, enhancing joint comfort and mobility and ultimately reducing joint pain. withinUs TruMarine™ Collagen also helps improve joint health by strengthening cartilage and overall joint structure. 

In addition, withinUs TruMarine™ Collagen helps maintain bone health, and restores bone mineral density. This helps reduce the risk of pain and stiffness associated with osteopenia and osteoarthritis.  



Our product slows down the aging process by providing the body with the nutritional building blocks it needs. In particular, marine collagen contains a higher level of the amino acids glycine, proline and hydroxyproline than other protein sources. These amino acids have been clinically proven to be key for collagen production and promoting healthy tissue growth by the cells themselves.

In addition to slowing the aging process, withinUs TruMarine™ Collagen helps reduce fine lines and wrinkles, reduces UVB-induced skin damage and increases skin hydration and suppleness - all are paramount for overall skin health.



It is important to know exactly what you are putting into your body - what it is made from, where it comes from, and the bioavailability. We are proud to be a transparent company, offering as much information possible to our customers, making your research easy.

Knowledge is power, so take the time and do the research - your body will thank you!

    I’m so glad I found Tru Marine Collagen. My skin is so much firmer and clear & my hair is shinier and a lot more healthy.

    I started using TruMarine collagen about two months ago for skin, hair, and joint pain. I noticed a substantial decrease in pain as well as stronger nails and shinier hair! Looking forward to seeing my skin go back in time. ;)

    I’ve noticed that my hair is growing faster than ever. Normally, my hair grows real slow, but since incorporating collagen in my diet, my hair lengthen has been increasing. I’m so happy because I’ll have my hair long just in time for summer.
