Natural Knee Support After 45: How Bone Broth May Help Your Joints
Many people over 45 begin to realize their knees are not as resilient as they once were. A sharp jab when climbing stairs, pushing yourself up slowly from a chair in the morning, or feeling every change in the weather in your joints—these are common signs that knee wear and tear is starting to show.
As we age, or carry extra weight, or move less, the cartilage in our joints gradually thins. This smooth cushion between bones becomes less protective, which can lead to discomfort, stiffness, and reduced mobility. Research suggests that more than 40% of adults over 50 experience some degree of knee joint degeneration, often related to osteoarthritis—one of the main causes of disability worldwide.
Alongside medical care and exercise, growing evidence points to nutrition as a quiet but powerful ally. Certain foods may help support joint tissues from within—one of them is a simple, traditional staple that a 97‑year‑old orthopedic surgeon still swears by.

A Veteran Orthopedic Doctor’s Simple Strategy
Dr. Ernesto Salazar, an orthopedic surgeon from Mexico with over seven decades of medical practice, remains strikingly active at age 97. He still walks on his own, stays mentally sharp, and attributes much of his joint resilience to consistent, natural nourishment rather than aggressive interventions.
In conversations about healthy aging, he often says:
“The body thrives on what nature provides. Simple, nutrient-rich foods can support joints more reliably over the long term than many complicated procedures.”
His favorite recommendation for knee and joint support is surprisingly modest: traditional bone broth.
Keep reading to see why this old-fashioned food is getting renewed scientific attention for joint health, especially for knees affected by aging or osteoarthritis.
Understanding Knee Joint Wear and Tear
The knee is one of the most heavily used joints in the body. At its core is cartilage, a smooth, rubber-like tissue that:
- Acts as a natural shock absorber
- Prevents bones from rubbing directly against each other
- Allows fluid, comfortable movement
Over time, several factors can gradually damage or thin cartilage:
- Repetitive daily use and mechanical stress
- Low-grade inflammation
- Nutrient deficiencies
- Previous injuries
- Excess body weight
As cartilage wears down, everyday tasks can become more challenging:
- Going up or down stairs feels painful or unstable
- Long walks or standing periods are tiring or uncomfortable
- Deep squats or kneeling feel risky or unpleasant
- Painkillers become a more frequent part of the routine
This process is common in osteoarthritis, where joint tissues lose their elasticity and resilience, leading to stiffness, pain, and reduced range of motion.
The encouraging news: diet can play a meaningful role in supporting joint maintenance. Research has identified specific nutrients—many found in collagen-rich foods—that may help protect cartilage and ease discomfort over time.
Why Bone Broth Is Getting So Much Attention
Bone broth is a nutrient-dense liquid made by simmering animal bones—typically from beef, chicken, or fish—for many hours. This slow cooking draws beneficial compounds out of the bones, cartilage, and connective tissue into the liquid.
During long simmering, the broth becomes rich in elements linked to joint and knee health, such as:
- Type II collagen – the primary protein in joint cartilage, helping maintain structure and flexibility
- Glycine and proline – amino acids crucial for building and repairing connective tissues
- Glucosamine and chondroitin – naturally occurring components that support joint lubrication and cushioning
When consumed warm, these nutrients provide the body with raw materials it can use for ongoing tissue repair and maintenance.
What Science Says About Collagen and Knee Pain
In recent years, scientists have taken a closer look at collagen and its derivatives:
- Reviews of several studies indicate that collagen intake can help improve comfort and function in people with osteoarthritis, particularly in the knees.
- Specific forms, such as undenatured type II collagen supplements, have shown promising results in clinical trials—reducing pain and improving mobility when used consistently.
Bone broth offers a whole-food source of similar components, although the scientific evidence is currently stronger for standardized collagen supplements. Still, many people prefer food-based approaches as part of their daily routine.
How Collagen Supports Knee Joint Health
From about age 35 onward, the body’s natural collagen production begins to slow down. This decline can:
- Increase friction within joints
- Contribute to stiffness and soreness
- Reduce the resilience of cartilage and surrounding tissues
By supplying collagen and its building blocks through food, you may help:
- Support the structure of cartilage
- Maintain smoother joint surfaces
- Promote more comfortable, flexible movement
Studies on collagen intake report:
- Reduced pain scores in people with knee problems
- Better daily function, such as walking and climbing stairs
- Benefits that typically appear after weeks to months of regular use
The key takeaway: collagen support is not an instant fix; it works gradually and is most effective with consistent intake.
Real-Life Experience: Bone Broth in Daily Routine
Many individuals who regularly consume bone broth report changes over time. For example:
- A 63‑year‑old woman with difficulty climbing stairs and significant morning stiffness began drinking one cup of homemade bone broth every day. Within a few weeks, she noticed less stiffness upon waking, and after a few months, walking stairs became more manageable.
These personal experiences are not the same as controlled scientific studies, but they reflect growing interest in using food-based strategies to complement traditional care for knee and joint health.
6 Ways Bone Broth May Support Joints and Overall Wellness
Bone broth is not just about collagen. It offers a combination of nutrients that can support your knees and general health in several ways:
-
Supplies raw materials for cartilage maintenance
- Provides collagen and amino acids that may help maintain joint cushioning.
-
Supports a balanced inflammatory response
- Contains glycine and other compounds that may help the body manage inflammation more effectively.
-
Provides key minerals for bone strength
- Often rich in calcium, magnesium, and phosphorus, which support bones surrounding the joints.
-
Promotes gut health and nutrient absorption
- A healthy digestive tract is essential for absorbing vitamins, minerals, and amino acids needed for joint repair.
-
May improve sleep and night-time recovery
- Glycine, abundant in bone broth, has been associated with better sleep quality for some people, which can aid nighttime tissue repair.
-
Supports skin elasticity as a bonus
- Collagen intake is also linked to smoother, more elastic skin—an added benefit alongside joint support.

How to Make Nourishing Bone Broth at Home
Preparing bone broth at home is straightforward and allows you to control quality and flavor.
Basic Bone Broth Recipe
-
Choose your bones
- Use about 1–2 kg (2–4 lbs) of bones: beef marrow bones, knuckles, chicken feet, wings, carcasses, or fish bones all work well.
-
Add water and vinegar
- Place bones in a large pot or slow cooker.
- Cover with plenty of water.
- Add 1–2 tablespoons of apple cider vinegar or another mild vinegar to help draw minerals from the bones.
-
Simmer slowly
- Bring to a gentle boil, then reduce heat to a low simmer.
- Cook for 8–24 hours (chicken and fish typically need less time; beef bones benefit from a longer simmer).
-
Strain and store
- Strain out bones and any solids.
- Let the broth cool.
- Store in the refrigerator for up to 5 days, or freeze in portions for longer storage.
-
Enjoy daily
- Drink about 1 warm cup per day, either on its own or as a base for soups and stews.
Flavor and Nutrient Boosters
For extra taste and added health benefits, consider adding during simmering:
- Turmeric (supports a healthy inflammatory response)
- Fresh ginger
- Garlic
- Onion, celery, carrots, or other vegetables
- Herbs such as parsley, thyme, or bay leaves
These additions can increase antioxidant content and make your broth more enjoyable.
Important Precautions and Considerations
Bone broth is generally safe for most people, but it is wise to consider the following:
-
Sensitive digestion
- If you have a delicate stomach or digestive issues, start with half a cup and increase gradually.
-
Watching cholesterol or fat intake
- Use leaner bones and skim off the hardened fat that forms on top after cooling.
-
Sodium awareness
- If you need to limit salt, go easy on added seasoning and use low-sodium ingredients.
-
Vegetarian or vegan options
- If you do not consume animal products, you can prepare mineral-rich vegetable broths with seaweed, mushrooms, and root vegetables. While they do not provide collagen, they can still support overall health.
-
Existing medical conditions
- Always check with your healthcare provider before making significant dietary changes, particularly if you have kidney disease, gout, severe heart conditions, or are on specific medications.
Remember: potential benefits build slowly and require consistent, long-term intake.
Boosting Results with Supportive Lifestyle Habits
Bone broth works best as one part of a holistic joint-care strategy. To get the most out of it, combine it with:
-
A nutrient-dense diet
- Emphasize fruits, vegetables, whole grains, healthy fats, and lean proteins.
- Include foods rich in vitamin C (like citrus and berries) to support collagen production.
-
Reduced intake of processed foods
- Minimize refined sugars, trans fats, and ultra-processed snacks that may promote inflammation.
-
Regular low-impact movement
- Activities like walking, swimming, cycling, and gentle yoga help keep joints mobile and muscles strong.
-
Healthy body weight
- Reducing excess weight can significantly lessen the load on your knees.
-
Prioritizing quality sleep
- Deep, restful sleep is when much of the body’s repair and regeneration occurs—including joint tissue.
These habits can amplify the joint-supporting effects of bone broth and improve overall well-being.

Frequently Asked Questions (FAQ)
1. How long does it take to feel any benefits from bone broth for joint pain?
Many people notice small improvements—such as reduced morning stiffness or slightly easier movement—after 2–4 weeks of daily intake. More noticeable changes often appear after 1–3 months of consistent use. Everyone is different, so results and timing vary.
2. Is bone broth better than collagen supplements for knee support?
They serve slightly different roles:
-
Bone broth
- Whole food
- Contains collagen, amino acids, and minerals
- Offers broader nutritional support
-
Collagen supplements (e.g., undenatured type II collagen)
- More concentrated and standardized
- Backed by stronger clinical evidence for specific outcomes like pain reduction and improved mobility in osteoarthritis
You do not necessarily have to choose one or the other. Many people use bone broth as a daily base, and some add a collagen supplement after discussing it with a healthcare professional.
3. Can I safely drink bone broth every day?
For most healthy adults, drinking bone broth daily is considered safe and can be a beneficial habit. Keep in mind:
- Use high-quality bones from reputable sources (ideally organic or pasture-raised)
- Avoid adding excessive salt
- Start with small servings if you have digestive sensitivities
If you have chronic health conditions or are on medication, consult your doctor before making bone broth a long-term daily routine.
4. Will bone broth alone cure osteoarthritis or knee problems?
No. Bone broth is not a cure for osteoarthritis or structural joint damage. It is best viewed as a supportive, nutritional tool that may:
- Help maintain cartilage
- Assist with joint comfort
- Complement medical treatments, physical therapy, and lifestyle changes
Always follow your doctor’s recommendations for diagnosis and treatment, and use dietary strategies as an additional layer of support.
5. Can I use store-bought bone broth instead of homemade?
