What Is Collagen? The Complete Guide to Your Body's Most Important Protein
GUIDE 01/04
Collagen
The raw material for the tendons and ligaments that transmit power — and the cartilage that keeps everyday movement comfortable.
Collagen is the most abundant protein in your body — the structural material your tendons, ligaments, cartilage and skin are largely built from. For anyone training hard, that makes it directly relevant to how efficiently force moves through your body in a sprint, a tackle, a swing or a jump. For anyone simply staying active as they age, it's just as relevant to how comfortably and freely you move day to day. Both are real, and both are why collagen is the cornerstone ingredient in OOST ReGen & Recover.
What Is Collagen?
Collagen makes up roughly 30% of your total protein content, found throughout your bones, muscles, skin, tendons, ligaments, cartilage and blood vessels. Think of it as the scaffolding that gives these tissues their structure, strength and elasticity — it's what allows them to withstand stretching, loading and repeated movement without breaking down.
Why Collagen Naturally Declines With Age
Your body's natural collagen production begins declining in your mid-20s and accelerates from there. By your 40s and 50s, you may have lost a significant amount of your natural collagen, which shows up as reduced joint mobility, stiffness, longer recovery after activity, and weaker connective tissue generally. For anyone training hard, that decline also means less efficient force transmission through tendons and ligaments that aren't being replenished as fast as they're being used.
Types of Collagen: Why Marine Collagen Stands Out
There are at least 28 types of collagen in the human body, but Type I is the most abundant, making up around 90% of your body's total collagen. It's found primarily in skin, tendons, ligaments and bone — exactly the tissue most relevant to both athletic performance and everyday joint comfort. Marine collagen, sourced from fish, is predominantly Type I, and research suggests it has meaningfully better bioavailability than bovine or porcine collagen — up to around 1.5 times better absorption.
How Collagen Supports Power Transmission and Everyday Comfort
For Competitive and High-Training-Load Athletes
Muscle generates force. Tendons and ligaments — built largely from collagen — are what transmit that force into every sprint, jump, tackle, swing or change of direction. If that connective tissue isn't conditioned to handle the load, some of the power your training builds never fully reaches the movement it's meant for, and the tissue itself carries more risk of injury under repeated stress. Supplying the body with hydrolysed collagen peptides gives it the raw material to build and maintain that transmission system.
For Recovery, Flexibility and Everyday Joint Comfort
You don't need to be training for competition for this to matter. As natural collagen declines with age, cartilage — the tissue that cushions your joints — gradually wears down, which shows up as stiffness, reduced range of motion and joints that just don't feel as easy as they used to. Supporting your body's collagen supply is one of the more direct ways to support that cushioning and flexibility, independent of any training programme — relevant whether you're walking, gardening, golfing, or simply staying on your feet through a busy day.
Who Benefits Most From Collagen Supplementation?
- Competitive athletes and high-training-load individuals, particularly in sports involving repeated contact, sprinting, jumping or heavy lifting.
- Active adults over 40, whose natural collagen production has already declined and for whom joint comfort and flexibility are often the priority in themselves.
- Anyone recovering from joint stress or a previous injury, where extra structural support can help.
- Anyone with an active lifestyle, full stop — you don't need a performance goal for stronger connective tissue and more comfortable joints to matter to your daily life.
OOST's Approach: Premium Marine Collagen
At OOST, we've prioritised marine collagen in ReGen & Recover for a few specific reasons:
ASC-Certified Sustainable Sourcing
Our collagen comes from an ASC-certified source — the first Pangasius producer in the world to achieve Aquaculture Stewardship Council certification, meaning responsibly farmed fish, consistent quality, and minimal environmental impact.
Hydrolysed for Fast Absorption
Our marine collagen is hydrolysed — broken down into smaller peptides your body can absorb quickly — and delivered in a liquid format rather than a tablet or capsule, for faster delivery to your tissues.
Informed Sport Certified
Every batch is independently tested for banned substances, so competitive and tested athletes can take it with confidence.
How Much Collagen Should You Take, and When?
Research on collagen supplementation generally uses doses between 2.5g and 15g per day depending on the goal, with research specifically looking at tendon adaptation — tendon stiffness and cross-sectional area — using doses of 15–30g per day alongside structured resistance training. OOST ReGen & Recover provides 8,000mg of hydrolysed marine collagen per sachet, alongside glucosamine, vitamin C and curcumin with piperine.
One sachet daily is the standard protocol. If you're training at a higher volume, two sachets a day brings your collagen intake to 16g — within the higher-dose range studied specifically for tendon adaptations. There's no safety concern in doing this: none of the formula's seven active ingredients approach an unsafe level at double the standard dose.
Timing matters too. On training days, we recommend taking it 30–40 minutes before you start — research shows collagen-building amino acids peak in the bloodstream roughly 30 to 60 minutes after intake, and taking it just before mechanical loading (your warm-up and session) means those building blocks are available right as your tendons and ligaments are being loaded. On rest days, take it with breakfast — your connective tissue doesn't stop remodelling just because you're not training, so a steady daily supply matters more than perfect timing on those days.
Frequently Asked Questions
Is collagen only useful for athletes?
No. While the power-transmission angle matters most for competitive athletes and heavy training loads, collagen's role in maintaining cartilage and connective tissue is just as relevant to everyday joint comfort and flexibility for anyone staying active, at any level.
Can I take two sachets of OOST ReGen & Recover in a day?
Yes. There's no safety concern across the formula's seven active ingredients at double the standard dose, and two sachets brings your daily collagen intake to 16g — within the 15–30g range some research has used specifically for tendon adaptations under heavy training loads. One sachet remains the standard daily protocol; two is worth considering if your training volume calls for it.
Can I get enough collagen from food?
Collagen-rich foods like bone broth can help, but supplementation provides a more concentrated and consistent daily dose, particularly for anyone with higher demands on their connective tissue.
Is marine collagen better than other types?
Marine collagen has shown meaningfully better bioavailability than bovine or porcine collagen — up to around 1.5 times better absorption — and is also a more sustainable option when responsibly sourced.
How long does it take to see results?
Most people notice initial changes within 2–4 weeks of consistent daily use, with fuller results typically appearing after 8–12 weeks. Collagen supports a structural rebuilding process, not an overnight change.
Is collagen safe for competitive or tested athletes?
Yes — look for an Informed Sport Certified product like OOST ReGen & Recover, so every batch is independently tested for banned substances.
Is OOST ReGen & Recover suitable for people with allergies?
It contains fish (pangasius) and shellfish-derived (crustacean, from the glucosamine) ingredients, so it isn't suitable for anyone with a fish or shellfish allergy.
The Bottom Line
Collagen works on two levels: it's the raw material for the tendons and ligaments that transmit the power competitive athletes train hard to build, and it's the same raw material behind the cartilage and joint comfort that matter to anyone staying active at any level. Whichever describes you, supporting your collagen supply — consistently, and timed right around training — is one of the more direct ways to support both.
Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle. If you have any pre-existing medical conditions, allergies, or are taking medication, consult your doctor before use.

Collagen is one of the main building blocks for your entire body.
We often hear how important collagen is for our skin’s consistency, giving it a youthful appearance. However, this is only part of collagen’s work, as it assists joints to remain flexible, which in turn allows more movement and exercise. Your joints will thank you for adding more into your diet.
Glucosamine is a natural substance that helps build and repair cartilage, the tissue that cushions joints. Healthy joints and cartilage are important for maintaining quality of life and to allow you to continue exercising as you age.
Chondroitin is a substance that occurs naturally in the connective tissue of humans, especially in joint cartilage. It is one of the building blocks of cartilage and helps joints maintain fluid and flexibility.
Curcuminoids are a group of active substances found in the turmeric root. These are known to have many health benefits including anti-inflammatory properties. It is also what gives turmeric its bright colour.
We have added Piperine, an extract from Black Pepper which aids the body in its absorption of Curcumin.
Vitamin C is a water-soluble vitamin and an important antioxidant. Our body does not store large quantities of Vitamin C, and we therefore depend on a regular intake from our diet or from supplements. Amongst other things, Vitamin C contributes to the normal production of collagen in the body and hence why it is an important component of the OOST ReGen & Recover product.
Vitamin D is now one of the most researched vitamins with a multitude of benefits. It plays a crucial role in enhancing bone health by aiding calcium absorption, it also supports muscle function and immune system strength. With mood-regulating benefits that contribute to overall well-being, making it a key component for maintaining vitality and longevity.
