There is a common misconception that marine collagen peptides are only for women. This couldn’t be further from the truth. withinUs TruMarine™ Collagen benefits men and women equally.





Collagen is often associated with skin health and beauty. While this is true, (taking 5 grams of withinUs TruMarine™ Collagen daily is clinically proven to improve the health of your skin, giving skin a ‘glow’ (hydration from within) minimizing fine lines and wrinkles) hydrolyzed marine collagen is equally important for men. withinUs TruMarine™ Collagen is clinically proven to help reduce the effects of UVB sun-induced skin damage, which is important for overall skin health.





Joint pain knows no gender. Osteoarthritis affects men and women (almost) equally and these aches and pains start off as minor discomforts but can grow to be debilitating as the body ages and continues to lose collagen. Reducing joint pain, increasing mobility and comfort becomes a top priority.

Incorporating a high quality, premium hydrolyzed marine collagen helps promote joint health by strengthening cartilage and joint structure and reducing joint pain (1). Unlike other sources of marine collagen (ie: fish skin), and animal skin and bone collagen, withinUs TruMarine™ Collagen has a superior absorption rate (bioavailability), meaning it is absorbed quickly and effectively. withinUs TruMarine™ Collagen is proven to encourage collagen production within the body reducing pain and inflammation associated with osteoarthritis.

“I was diagnosed by my doctor and the hospital where I had my MRI done. I was told that I had moderate to severe arthritis. This seemingly came out of nowhere. I immediately went out and purchased a very expensive custom brace to help to mitigate the pain that I found myself in. It was then that I began taking withinUs TruMarine™ Collagen. After taking withinUs TruMarine™ Collagen for about 7-8 months, the pain that I was dealing with daily has now, for the most part, become a thing of the past” -Nicholas Lea





Athletes, and aging ex-athletes of all levels can experience the benefits of withinUs TruMarine™ Collagen. Our collagen is 95% protein ad 5% moisture. Due to this composition, ingesting withinUs TruMarine™ Collagen has been shown to help with lean muscle gain, and post-workout recovery. 

Athletes notice that after 2-3 months of taking our product, their body appears more ‘toned’ without changing their regular exercise and eating regimes. Many professional and high-performance athletes agree that ingesting collagen is a highly effective, and natural, workout recovery. Whether you are an elite athlete or someone that likes to hike, run, bike etc. it is likely you have experienced muscle and/or joint soreness after a strenuous workout.

Significant improvement has been shown in regards to knee joint comfort after 6 months of ingesting hydrolyzed marine collagen (2). withinUs TruMarine™ Collagen does not eliminate post-exercise muscle soreness, but the 18 amino acids in our collagen help to repair your muscles, tendons and joints post exercise. 

"After my clavicle surgery last May I was having pain in my shoulder joint. I had a previous surgery on that shoulder which probably didn’t help 🤷🏻‍♂️ I spent most of the summer rehabbing which helped the function a ton but it still ached. I did some research and found people were experiencing positive results with collagen supplements so I figured I’d give it a shot. I’ve been using @withinusnatural TruMarine Collagen everyday for the past few months and the joint pain I was experiencing is mostly gone! I like to keep a few of the Rehydrate+TruMarine Collagen electrolyte packets in my gym bag to help keep me going. Give it a try! Thanks for the support."
