The Ancient Remedy Meets Modern Wellness

Bone broth has been consumed across cultures for thousands of years — from Chinese medicinal soups to European peasant cooking, the practice of simmering bones for their nourishing liquid is as old as cooking itself. In recent years, it's had a major wellness revival. But what does the science actually support? Let's separate fact from hype.

What's in Bone Broth?

When bones are simmered for an extended period, they release a range of compounds into the liquid:

  • Collagen — breaks down into gelatin during cooking, which provides the characteristic jiggly texture of a good stock when chilled.
  • Amino acids — including glycine, proline, and hydroxyproline, which are building blocks for connective tissue.
  • Minerals — calcium, magnesium, phosphorus, and potassium leach from bones into the broth over time.
  • Glucosamine and chondroitin — found in cartilage-rich bones, these compounds are commonly found in joint health supplements.

Potential Benefits — and What Evidence Exists

Joint Health

Gelatin and collagen peptides have been studied for their potential to support joint cartilage. Some research suggests that collagen supplementation may help reduce joint discomfort in active individuals, though most studies use concentrated collagen supplements rather than broth specifically. Bone broth is a natural dietary source of these compounds, but the concentration varies widely depending on how it's made.

Gut Health

Gelatin has a long folk history as a digestive aid. It's thought to help maintain the integrity of the gut lining. Some preliminary research on gelatin and glycine is promising, though large-scale human trials on bone broth itself are still limited. The amino acid glutamine (found in broth) has been more extensively studied for gut health support.

Sleep and Relaxation

Glycine, an amino acid abundant in bone broth, has been studied for its calming effects on the nervous system. Some research suggests glycine supplementation may improve sleep quality and reduce fatigue — making an evening cup of warm broth a potentially restful habit.

Protein and Satiety

Bone broth is a low-calorie source of protein, making it a useful tool for those watching their intake. A warm mug of broth can be surprisingly satisfying and may help curb appetite between meals.

Important Caveats

  • Most robust research is on isolated collagen peptides or amino acids — not on broth itself. Don't expect miraculous results.
  • Lead content in bone broth has been flagged in some studies. Using high-quality, organic, grass-fed bones may reduce this risk.
  • Bone broth is high in sodium — factor this in if you're monitoring salt intake.
  • It is not a replacement for a balanced diet — think of it as a nutritious complement, not a cure-all.

How to Maximize Nutritional Value

  1. Add a splash of apple cider vinegar when making broth — it helps draw minerals from the bones.
  2. Simmer for at least 8–12 hours for chicken bones, 12–24 hours for beef bones.
  3. Use joints and knuckles — these are rich in collagen-producing cartilage.
  4. Include feet (chicken feet especially) for extremely gelatin-rich broth.

Bone broth is genuinely nutritious, deeply comforting, and a wonderful base for soups and stews. Enjoy it for what it is — a nourishing, traditional food — rather than a miracle supplement.
