10 Science-Backed Bone Broth Benefits (2026 Guide)
Bone broth isn't new. Your grandmother made it. Her grandmother made it. Cultures across the world have been simmering bones for centuries.
What's new is the research explaining *why* it works. The collagen. The amino acids. The minerals. Scientists are finally catching up to what traditional cooks knew instinctively.
Here's what bone broth actually does for your body — backed by research, not marketing hype.
## What Is Bone Broth?
Bone broth is the liquid you get from simmering animal bones for 24-48 hours. That long cooking time matters — it breaks down collagen into gelatin and releases minerals from the bone matrix into the water.
The result is a nutrient-dense liquid containing:
- **Collagen/gelatin** — the protein that holds your body together
- **Glycine, proline, glutamine** — amino acids for gut and joint health
- **Calcium, magnesium, phosphorus** — minerals from the bones themselves
- **Glucosamine and chondroitin** — compounds from cartilage that support joints
This isn't regular stock. Stock simmers for 4-6 hours. Bone broth simmers for 24-48 hours. That difference extracts far more of the good stuff.
## The 10 Evidence-Backed Benefits
### 1. Gut Health and Digestion
Glutamine — an amino acid abundant in bone broth — is the primary fuel source for the cells lining your intestine. When those cells are healthy, they form a tight barrier that keeps unwanted particles from passing into your bloodstream.
Research published in the *Journal of Clinical Gastroenterology* found that glutamine supplementation improved intestinal barrier function in patients with intestinal permeability issues. Bone broth delivers glutamine in a bioavailable form, alongside glycine which reduces inflammation in the gut lining.
If you've ever been told to "heal your gut," bone broth is a good starting point.
### 2. Joint Support and Mobility
The collagen in bone broth breaks down into compounds your body uses to maintain cartilage — the cushioning between your joints.
A 2016 study in the *Journal of Agricultural and Food Chemistry* showed that collagen hydrolysate (what you get from broken-down collagen) accumulates in cartilage tissue after consumption. Another study found that athletes taking collagen supplements reported significantly less joint pain during activity.
Bone broth also contains glucosamine and chondroitin — compounds extracted from the cartilage on bones. These are the same compounds sold as joint supplements, but in a food-based form your body recognises.
### 3. Skin, Hair, and Nail Health
Your skin is 75-80% collagen. As you age, collagen production declines — roughly 1% per year after age 20. This is why skin wrinkles, sags, and loses elasticity.
A 2019 study in *Nutrients* found that oral collagen supplementation significantly improved skin elasticity and hydration after 8 weeks. Participants also showed increased collagen density in the dermis layer.
The amino acids in bone broth (glycine and proline) are building blocks for collagen synthesis. Drinking bone broth won't make you 20 again, but it gives your body raw materials to maintain the skin you have.
### 4. Better Sleep Quality
Glycine — present in high amounts in bone broth — has been studied as a sleep aid. A 2012 study in *Sleep and Biological Rhythms* found that 3 grams of glycine before bed improved subjective sleep quality and reduced daytime fatigue.
Glycine works by lowering core body temperature, which signals to your brain that it's time to sleep. It also has calming effects on the central nervous system.
A cup of bone broth in the evening delivers roughly 2-3 grams of glycine — enough to potentially affect sleep quality.
### 5. Immune System Support
The amino acids in bone broth — particularly arginine and glutamine — play roles in immune function. Glutamine is fuel for immune cells. Arginine is involved in wound healing and immune response.
There's also a reason "chicken soup" is prescribed for colds across cultures. Research from the University of Nebraska Medical Center found that chicken soup (made with bones) had anti-inflammatory properties that could help reduce symptoms of upper respiratory infections.
Bone broth won't cure your cold. But it may help your body fight it more effectively.
### 6. Muscle Recovery and Athletic Performance
The protein in bone broth is primarily collagen, which differs from muscle proteins like whey. But collagen has its own role in athletic performance.
A 2017 study in the *American Journal of Clinical Nutrition* found that collagen supplementation combined with exercise increased muscle mass and strength in elderly men with sarcopenia. Other research suggests collagen supports tendons and ligaments — the connective tissues athletes stress during training.
For recovery, the glycine in bone broth also has anti-inflammatory effects that may help reduce post-workout soreness.
### 7. Bone Health and Mineral Support
Bone broth is made from bones. Unsurprisingly, it contains bone minerals — calcium, magnesium, and phosphorus leach into the liquid during simmering.
While mineral content varies based on cooking method and bone type, bone broth provides these minerals in a form that's easily absorbed. The gelatin matrix may enhance mineral bioavailability compared to supplements.
This doesn't replace calcium-rich foods or supplements if you're deficient. But it contributes to overall mineral intake.
### 8. Weight Management
Bone broth is nutrient-dense but relatively low in calories — roughly 40-50 calories per cup. It's satiating because of its protein and gelatin content, which can help control appetite.
Some people use bone broth as part of intermittent fasting protocols. The protein and amino acids help maintain muscle during fasting windows while providing minimal calories.
It's not a magic weight loss solution. But as a replacement for higher-calorie snacks or meals, it can support weight management goals.
### 9. Hydration and Electrolytes
Bone broth contains electrolytes — sodium, potassium, and magnesium — that support hydration. Unlike plain water, these electrolytes help your body retain fluid more effectively.
For people following low-carb or ketogenic diets (which can deplete electrolytes), bone broth is a popular way to maintain mineral balance. It's also gentler on the stomach than electrolyte drinks loaded with sugar or artificial ingredients.
### 10. Easy Digestion
Unlike many protein sources, bone broth is easy to digest. The proteins are already broken down from long simmering. There's no fibre that might irritate a sensitive gut.
This makes bone broth useful during illness, after surgery, or any time your digestive system needs a break. It provides nutrition without making your gut work hard.
## How Much Bone Broth Should You Drink Daily?
Most research on collagen benefits uses doses of 2.5-15 grams of collagen per day. A cup of bone broth contains roughly 6-12 grams of collagen (depending on concentration).
**For general wellness:** 1 cup (240ml) daily
**For targeted benefits (joint health, gut healing):** 2-3 cups daily
**For fasting protocols:** 3-5 cups on fasting days
Consistency matters more than quantity. Daily consumption for 8-12 weeks is when most people notice changes in skin, joints, and energy.
## How to Choose a Quality Bone Broth
Not all bone broths are equal. Here's what to look for:
**Grass-fed bones:** Animals raised on pasture produce bones with higher nutrient content and fewer toxins.
**Long simmering time:** At least 24 hours for beef bones. Less than that and you're buying expensive stock.
**High gelatin content:** Quality broth gels when cold. If it stays liquid, the collagen wasn't properly extracted.
**No fillers or additives:** Many commercial broths add thickeners, flavourings, or preservatives. Check the ingredients.
**Proper concentration:** Liquid bone broth is mostly water. Concentrates deliver more nutrition per serving without shipping charges for water weight.
## Our Approach at Best Bone Broth
We use bones from grass-fed cattle raised in Australia and New Zealand — some of the world's cleanest pastures. No antibiotics, no hormones.
Our broth simmers for 48 hours to maximise collagen extraction, then gets reduced to a concentrated paste. Each 350g jar makes 35 servings — just add hot water.
That concentration means you get the equivalent of litres of homemade broth in a jar that fits in your cupboard. And at roughly 50p per serve, it's cheaper than making your own when you factor in quality bones and time.

## FAQ
### Is bone broth actually good for you?
Yes, backed by research. The collagen, amino acids, and minerals in bone broth support gut health, joints, skin, and immune function. The key is quality broth made from grass-fed bones simmered for 24+ hours.
### How quickly do you see benefits from bone broth?
Some effects (like improved digestion) can happen within days. Others (like skin and joint improvements) typically take 8-12 weeks of consistent daily consumption.
### Is bone broth better than collagen supplements?
Both work. Bone broth provides collagen plus amino acids, minerals, and other compounds in a food matrix. Collagen supplements are more concentrated. Many people use both — broth for daily nutrition, supplements for targeted doses.
### Can you drink too much bone broth?
It's difficult to overdo. Some people drink 3-5 cups daily without issues. If you're watching sodium intake, check the sodium content of your broth. Our concentrate is naturally low in sodium.
### What's the best time to drink bone broth?
Morning works for an energising start. Evening works for sleep (glycine content). Before meals works for digestion. There's no wrong answer — consistency matters more than timing.
