Pure Collagen vs Bone Broth: How to Choose the Right Formula

You're looking at our product range.

Pure Collagen. Bone Broth. Both contain collagen. Both support joints.

Which one should you choose?

Here's the honest breakdown of what each formula does, who they're for, and how to decide.

The Core Difference

Pure Collagen = Maximum collagen content, clinical-grade supplement

Bone Broth = Whole-food approach, collagen + nutrients + flavour

Think of it like:

Pure Collagen is a targeted supplement. Bone Broth is food-based nutrition.

Both work. They work differently.

Pure Collagen: The Details

Pure Collagen

What's in it:

One ingredient:

• 100% hydrolysed collagen peptides (Types I & III)

• From grass-fed cattle

• Nothing else

Collagen content per serving:

• 6,000mg of pure collagen in a 2 teaspoon (6g) serving

• 90-95% protein content

• Zero filler

How it works:

Absorbed intact from gut → enters bloodstream → accumulates in target tissues (joints, skin, tendons) → stimulates collagen production

This is the mechanism proven in clinical studies.

Form:

Side-by-Side Comparison

The Collagen Content Question

"If Pure Collagen has 6,000mg and Bone Broth has 4,000mg, is Pure Collagen 50% better?"

Not exactly. Here's why:

Pure Collagen: 6,000mg hydrolysed peptides

• 100% broken down into small peptides (2,000-5,000 Da)

• Maximum bioavailability

• Proven absorption in studies

Bone Broth: 4,000mg collagen + gelatin

• Collagen: Fully hydrolysed (small peptides, high absorption)

• Gelatin: Partially hydrolysed (larger molecules, moderate absorption)

• Plus: Glucosamine, minerals, amino acids

Think of it like:

Pure Collagen is a concentrated supplement.
Bone Broth is nutrient-dense food.

Both deliver collagen. Bone Broth delivers more than just collagen.

Who Should Choose Pure Collagen?

Choose Pure Collagen if:

1. You want maximum collagen intake

If your dog needs full daily servings for:

• Diagnosed hip or elbow dysplasia

• Post-injury recovery

• Senior dog with significant arthritis

• Large breed on the 31kg and over serving (4 teaspoons, 12g daily)

Pure Collagen delivers 6,000mg in a 2 teaspoon serving.

2. Your dog eats their food normally

If your dog:

• Eats kibble or wet food without fussing

• Doesn't notice tasteless powder mixed in

• Has no issues with supplements in general

Pure Collagen works perfectly. No need for flavouring.

3. You want best value per mg of collagen

If cost-effectiveness matters:

• Pure Collagen: £0.18 per 1,000mg collagen

• Bone Broth: £0.21 per 1,000mg collagen

Pure Collagen is 14% cheaper per mg of collagen.

4. You have multiple dogs of different sizes

If you need to serve precisely:

• Dog 1 (8kg): 1 teaspoon Pure Collagen

• Dog 2 (20kg): 2 teaspoons Pure Collagen

• Dog 3 (35kg): 4 teaspoons Pure Collagen

Tasteless powder = easy to give different amounts to each dog.

5. You're focused purely on joint/skin/coat support

If your only goal is collagen supplementation:

• Maximum collagen content

• No extra nutrients needed

• Clinical-grade approach

Pure Collagen is the right choice.

Who Should Choose Bone Broth?

Choose Bone Broth if:

1. Your dog is a picky eater

If your dog:

• Refuses food with powder mixed in

• Can detect even tasteless supplements

• Leaves food in bowl if anything is added

Bone Broth's beef flavour makes it irresistible.

Most picky eaters will lick the bowl clean when you mix Bone Broth with warm water and pour over food.

2. Your dog has digestive issues

If your dog experiences:

• Sensitive stomach

• Occasional diarrhoea

• Food sensitivities

• IBD or chronic gut issues

Bone Broth supports gut health:

• Gelatin soothes gut lining

• Glutamine (amino acid) supports intestinal cells

• Easy to digest

• Gentle on sensitive stomachs

Pure Collagen doesn't directly target the gut the way Bone Broth does.

3. Your dog needs hydration support

If your dog:

• Doesn't drink enough water

• Recovering from illness/surgery (needs fluids)

• Hot weather hydration

• Elderly dog who forgets to drink

Bone Broth mixed with water = flavoured liquid dogs love to drink.

You're getting collagen + encouraging fluid intake.

4. You prefer whole-food nutrition

If your philosophy is:

• Food-based supplements over isolated compounds

• Want multiple nutrients, not just collagen

• Prefer traditional remedies (bone broth has been used for centuries)

Bone Broth aligns with this approach:

• Collagen + gelatin + minerals + glucosamine

• Real food, not just extracted protein

• Grandmother would recognise it

5. Your dog is recovering from surgery or illness

If your dog:

• Won't eat solid food post-surgery

• Needs appetite stimulation

• Requires easy-to-digest nutrition

• Needs to maintain weight during recovery

Bone Broth as gravy:

• Appetising smell and taste

• Easy to consume (liquid form)

• Nutrient-dense

• Supports recovery

Vets often recommend bone broth for post-op recovery.

Can You Use Both Together?

Yes. They're complementary, not competing.

Example routine:

Morning: Pure Collagen mixed into breakfast
Evening: Bone Broth mixed with water, poured over dinner

Give each product at the serving for your dog's weight as printed on its own pack. Don't add the two together to reach a target figure.

Benefits of combining:

• Collagen from two different sources

• Gut support from Bone Broth

• Mineral support from Bone Broth

• Hydration from evening gravy

• Comprehensive approach

Who should do this:

• Large dogs with severe arthritis

• Post-surgery recovery (maximum support)

• Senior dogs needing all-around support

• Working dogs under heavy load

Cost for a dog of 11 to 20kg:

• Pure Collagen: £1.07/day

• Bone Broth: £0.83/day

• Total: £1.90/day

Is it worth it?

If your dog has serious joint issues or you want to prevent problems in a high-risk breed, combining both formulas provides broader support.

The Gut Health Factor

This is where Bone Broth has a unique advantage.

Why gut health matters for joints:

Leaky gut = systemic inflammation = worse arthritis

The connection:

1. Damaged gut lining allows undigested food particles into bloodstream

2. Immune system attacks these particles

3. Creates chronic inflammation throughout body

4. Inflammation accelerates joint damage

Bone Broth helps:

• Gelatin "patches" gut lining

• Glutamine (amino acid) supports intestinal cells

• Reduces gut permeability

• Decreases systemic inflammation

If your dog has both joint issues AND digestive problems, Bone Broth addresses both.

Pure Collagen only addresses joints directly.

The Flavour Question

"My dog won't eat tasteless powder. Should I only use Bone Broth?"

Try this first:

Method 1: Mix Pure Collagen with Bone Broth

• Make Bone Broth gravy (Bone Broth serving for your dog's weight + warm water)

• Add the Pure Collagen serving for your dog's weight to the gravy

• Pour over food

Result:

• Collagen from both formulas in one bowl

• Beef flavour masks any texture from Pure Collagen

• Best of both formulas

Method 2: Hide Pure Collagen in smelly food

• Mix Pure Collagen into:

• Sardines

• Tuna

• Raw egg

• Wet food (strong-smelling varieties)

Most dogs won't notice tasteless powder when mixed with pungent food.

Method 3: Start with Bone Broth, transition to Pure Collagen

Week 1-2: Only Bone Broth (get them used to something in food)
Week 3: 75% Bone Broth + 25% Pure Collagen
Week 4: 50/50 mix
Week 5: 25% Bone Broth + 75% Pure Collagen
Week 6+: Only Pure Collagen

Gradual desensitisation works for many fussy eaters.

Common Questions

"Can I alternate between them?"

Yes.

Example:

• Monday/Wednesday/Friday: Pure Collagen

• Tuesday/Thursday/Saturday: Bone Broth

• Sunday: Both

Benefit: Variety in nutrients while maintaining collagen intake.

Which one works faster?"

Both work at similar speeds.

Collagen accumulation timeline:

• Week 2-4: Skin/coat improvements

• Week 4-6: Mobility improvements

• Week 8-12: Maximum benefit

This timeline is the same for Pure Collagen and Bone Broth.

What matters is:

• Consistent daily use

• The correct serving for your dog's weight

• Patience (you're rebuilding tissue)

"I can't decide. What should I do?"

Start with Pure Collagen.

Why:

• Works for 95% of dogs

• Maximum collagen content

• Best cost-effectiveness

• You can always switch to Bone Broth if needed

Give Pure Collagen 2 weeks.

If your dog refuses it or has digestive issues, then switch to Bone Broth.

Most dogs accept Pure Collagen without issue.

"My dog has severe arthritis. Should I use both?"

Yes, if you can afford it.

Severe arthritis benefits from:

• Collagen from both formulas, each given at its own pack serving

• Gut support (Bone Broth's gelatin)

• Minerals (Bone Broth)

• Comprehensive approach

Cost for a dog of 11 to 20kg: £1.90/day (both formulas)

Compare to: Surgery (£5,000-8,000) or chronic pain medication (£50-100/month + side effects)

Supporting joints comprehensively is worth the investment.

"Which one is better for skin and coat?"

Pure Collagen.

Why:

• Higher total collagen per serving (6,000mg vs 4,000mg)

• Collagen is the primary structural protein in skin

But Bone Broth also helps:

• Gelatin supports skin from within

• Minerals support overall health

For primary skin/coat concerns: Pure Collagen
For skin + other issues: Bone Broth is fine too

The Bottom Line

Pure Collagen:

• Maximum collagen content

• Clinical-grade supplement

• Best for most dogs

• Most cost-effective

Bone Broth:

• Whole-food nutrition

• Supports gut health

• Perfect for picky eaters

• Multiple nutrients beyond just collagen

Both work. Neither is "better."

Choose based on:

• Your dog's needs

• Their eating habits

• Your nutrition philosophy

• Your budget

Or use both together, each at its own pack serving.

What matters most: Consistent daily supplementation with quality collagen.

Whether that comes from Pure Collagen, Bone Broth, or both, your dog's joints will thank you.
