What's Actually in Our Bone Broth Kit, and What the Collagen Research Shows

Bone broth claims range from "delicious and comforting" to "cures everything," and the honest answer sits somewhere more specific than either. We sell the bones, the seasoning, and the recipe, not a miracle in a jar. Here's exactly what's in our kit, and a straight look at what the collagen research supports.

Quick answer: Our Bone Broth Kit includes REP beef, chicken, or pork bones, one of our seasoning blends, and an emailed recipe, simmered at home for up to 24 hours. The strongest clinical evidence for collagen's skin and joint benefits comes from concentrated collagen peptide supplements, not broth itself, which no trial has directly tested. Broth still delivers gelatin, minerals, and flavor, just not the same standardized dose as a supplement.

What's Actually in the Kit

Our Homemade Bone Broth Kit pairs REP beef or chicken bones with one of our seasoning blends and a recipe card, built for a slow cooker or Instant Pot [1]. We also sell beef bones, chicken bones and feet, and heritage pork bones separately for anyone building their own recipe from scratch, and Tallowstix if you want rendered fat on hand too. Store-bought broths are typically watered down and don't contain the same gelatin and collagen content as broth simmered from bones at home.

The Research That Actually Exists

A 2026 meta-analysis in Aesthetic Surgery Journal Open Forum, reviewing 113 randomized controlled trials involving nearly 8,000 participants, found consistent benefits from collagen supplementation for skin elasticity and hydration, along with meaningful relief from osteoarthritis joint pain and stiffness [2]. It found less convincing results for oral health, cardiometabolic markers, and post-exercise muscle recovery.

The Part Worth Being Honest About

Here's the distinction that matters: that research is on concentrated, standardized hydrolyzed collagen peptide supplements, not on bone broth itself. No clinical trial has directly tested broth for these outcomes, and broth's collagen content varies widely depending on the bones used and how long it simmers [2]. Broth protein is also incomplete on its own, since it lacks meaningful tryptophan, so it's a food worth enjoying rather than a replacement for complete protein sources like eggs, fish, or the beef and chicken we also sell [3]. We'd rather you know that distinction going in than assume broth and a supplement do the identical job.

Why Our Bones Are Different Anyway

Whatever the collagen question settles into, the source of the bones still matters. Bones from cattle raised on healthier, regeneratively managed soil and forage produce broth with better mineral content and flavor, since soil and forage quality directly shape what ends up in an animal's tissue and bones [4] — the same soil-to-nutrient chain behind our lab-tested beef. Regenerative farming goes further than organic on this specific point: organic avoids synthetic inputs, but regenerative practices like rotational grazing actively rebuild soil, improve water cycles, and increase biodiversity [4].

Key Takeaways

• Our Bone Broth Kit includes bones, a seasoning blend, and an emailed recipe, not a powder or pre-made carton
• A 2026 meta-analysis of 113 RCTs found skin and joint benefits from concentrated collagen supplements specifically, not broth
• No trial has directly tested bone broth for these outcomes, and broth's collagen content varies with how it's made
• Regardless of the collagen question, bones from regeneratively raised cattle reflect the same soil-to-nutrient chain behind our lab-tested beef

Frequently Asked Questions

What's the difference between REP's Bone Broth Kit and store-bought broth?

Our kit gives you REP beef, chicken, or pork bones, a seasoning blend, and a recipe card to make broth at home, simmered up to 24 hours. Store-bought broths are typically watered down and don't contain the same amount of gelatin and collagen as broth made from scratch.

Does bone broth actually provide the same collagen benefits as supplements?

Not exactly the same. The clinical research showing skin and joint benefits comes from standardized, concentrated hydrolyzed collagen peptide supplements. No clinical trial has directly tested bone broth itself for these outcomes, and broth's collagen content varies significantly depending on how it's made.

What are the benefits of regenerative meat vs. conventional meat in terms of nutrition?

Bones from cattle raised on healthier, regeneratively managed soil and forage produce broth with better mineral content and flavor, since soil and forage quality directly shape what ends up in an animal's bones and tissue.

How long should I simmer bone broth to get the most collagen?

Authentic bone broth typically simmers for up to 24 hours, longer than a quick stock, to pull out more collagen, gelatin, and minerals from the bones and connective tissue.
