Bovine collagen: type I and III peptides for joints, tendons and skin
Bovine collagen is collagen extracted from cattle hide and hydrolysed into short peptides your gut can absorb, and it is the source used in most of the tendon, joint and body-composition research. It provides both type I and type III collagen, which is why it suits people who want to look after connective tissue as well as skin. Every KUDU sachet delivers 20,000mg of hydrolysed bovine collagen peptides in a 63ml ready-to-drink shot, with 0g sugar and 85 calories, made in the UK and Informed Sport certified. Not beauty collagen. Performance collagen.

What bovine collagen is, and why type I and III matter
Collagen is the structural protein in skin, tendons, ligaments, bone and cartilage. Bovine collagen is taken from cattle hide, then broken down by enzymes (hydrolysed) into peptides small enough to pass through the gut wall and reach the bloodstream. Whole collagen is too large to absorb efficiently, which is why "hydrolysed collagen" and "collagen peptides" mean the same thing and are the form used in trials. The explainer is in hydrolysed collagen vs collagen peptides, and the absorption science in how collagen is absorbed.
Type I collagen is the most abundant type in the body and dominates skin, tendon and bone. Type III sits alongside it in skin, blood vessels and muscle. Bovine sources naturally contain both; marine collagen is almost entirely type I. For a product aimed at connective tissue and skin together, bovine is the more complete source.

Bovine vs marine collagen
| Feature | Bovine collagen (KUDU) | Marine collagen |
|---|
| Source | Bovine hide, hydrolysed | Fish skin and scales |
| Collagen types | Type I and III | Mainly type I |
| Research base | Most tendon, joint, bone and strength studies | Mostly skin studies |
| Typical dose per serving | 20,000mg per KUDU sachet | Commonly 2,500β10,000mg |
| Cost per 1,000mg | 12.5p one-time | Usually higher per gram |
| Suitable for | Not vegetarian; dairy and gluten free | Not vegetarian; pescatarian-friendly |
Once hydrolysed, bovine and marine peptides look similar to the gut. The practical differences are the type mix, the cost of hitting a 15 to 20g dose, and the studies behind each. The full comparison is in marine vs bovine collagen.
Who bovine collagen is for
Tendons, ligaments and joints
Praet 2019 gave 2.5g daily for six months and reported better Achilles tendinopathy outcomes alongside rehab. Dressler 2018 used 5g for six months in chronic ankle instability, and Jerger 2022 found changes in Achilles cross-sectional area after 14 weeks at 5g. Zdzieblik 2017 (5g, 12 weeks) looked at activity-related knee pain and Clark 2008 (10g, 24 weeks) at joint pain in athletes. Read does collagen help joint pain, collagen for tendonitis and collagen for plantar fasciitis.
Strength, recovery and body composition
Zdzieblik 2015, Kirmse 2019 and Jendricke 2019 each combined 15g of collagen peptides a day with 12 weeks of resistance training and reported improvements in body composition and strength versus training alone. Clifford 2019 used 20g a day for nine days around damaging exercise and looked at soreness. One KUDU sachet covers the 15 to 20g those trials used. See how collagen aids recovery and collagen vs whey protein.
Skin, bone and the over-50s
Proksch 2014 found improvements in skin elasticity at 2.5g and 5g over eight weeks, and de Miranda 2021 pooled the skin trials in a meta-analysis. KΓΆnig 2018 gave 5g a day for 12 months to postmenopausal women and measured bone mineral density. At 20g, a KUDU sachet clears every one of those doses. Start with collagen for bone density, collagen and menopause and collagen for the over-50s.
How to take bovine collagen
- Pick a dose from the studies. Skin trials used 2.5 to 10g, tendon and joint trials 2.5 to 10g, strength and recovery trials 15 to 20g. One 20g sachet covers all of them. See how much collagen per day.
- Training days: 30 to 60 minutes before your session, following Shaw 2017's timing. Vitamin C supports normal collagen formation, so pair it with fruit or take the Collagen + Creatine sachet, which includes it.
- Every day for 8 to 12 weeks minimum. Tendon and bone studies ran six to twelve months. Timeline in how long collagen takes to work.
- Keep it in proportion. Paul 2019 concluded collagen can safely make up around 36% of daily protein intake; it is not a complete protein, so keep eating meat, fish, dairy, eggs or pulses for the rest.

Bovine collagen FAQs
What is bovine collagen made from?
Bovine hide, which is hydrolysed into collagen peptides. KUDU delivers 20g of hydrolysed bovine collagen in a ready-to-drink 63ml sachet, made in the UK.
Is bovine collagen better than marine collagen?
For connective tissue, strength and bone, bovine has the larger evidence base and supplies type I and III. For skin alone both have supporting trials. Bovine is usually the cheaper way to reach a 15 to 20g dose.
Is KUDU bovine collagen halal or kosher?
KUDU is not halal or kosher certified. It is a bovine-source product. If certification matters to you, contact us before ordering and we will tell you exactly what we can and cannot confirm about the supply chain.
How much bovine collagen should I take a day?
The published trials used 2.5g to 20g a day depending on the goal. One KUDU sachet gives 20g, the top of that range, so one a day is enough for any of the studied outcomes.
Is bovine collagen safe, and are there side effects?
Hydrolysed collagen is a food protein and is generally well tolerated. A small number of people report mild fullness or an aftertaste. It is not suitable for anyone with a beef allergy. Full notes in collagen side effects.
Is bovine collagen dairy free and gluten free?
Yes. KUDU bovine collagen is dairy free and gluten free. It comes from cattle hide, not milk, so it contains no lactose or milk protein. Browse the full range on the liquid collagen collection.
