As modern diets drift further from traditional foods like bone-in meats and gelatinous bone broths, joint issues are becoming increasingly common. Many people recognise the problem but reach straight for synthetic glucosamine and chondroitin supplements. The truth? Bulletproof joints are built through nutrient-rich whole foods, not poorly absorbed synthetic bandaids.

The good news: adding these nutrients back into your diet is remarkably simple, and your body responds quickly to bioavailable, whole-food forms.

Important context before we begin: These nutrients rebuild joint integrity and strength, they won't necessarily reduce existing pain (that's a separate discussion). Also, resistance training is essential for strong joints and bone density, while avoiding repetitive strain from activities like long-duration running gives your joints time to recover.

1. Collagen (the structural backbone)

Collagen is the foundational protein of cartilage, tendons, ligaments, and joint capsules. It provides the structural framework that holds your joints together and allows them to withstand stress and movement. There's a reason collagen has exploded in popularity, not just for skin or gut health, but it's absolutely key for joint health.

When modern diets turned away from slow-cooked bone-in meats and swapped these for convenience foods, people's joints struggled. While collagen powder offers an easy boost, we still recommend slow-cooked meats and broths in addition.

Best sources: Bone broth (12+ hours from joints and knuckles), slow-cooked bone-in meats (oxtail, short ribs, chicken with skin), quality grass-fed collagen powder.

2. Gelatine (highly usable collagen)

Gelatine is a highly bioavailable form of collagen that supplies glycine and proline, amino acids crucial for joint repair and cushioning. This nutrient has been left behind and even demonised by the candy industry, which once relied heavily on it but is now quickly moving to vegan options.

Anyone who's cooked a long bone broth has seen the gelatinous jiggly texture when it cools. This used to be such a common part of people's diets but has been lost to convenience and the vilification of animal products.

Best sources: Homemade bone broth (the jigglier, the better), grass-fed gelatine powder, slow-cooked meats with connective tissue, gelatine gummies

3. Glycine (drives joint resilience)

Glycine is the amino acid that drives collagen cross-linking, shock absorption, and long-term joint resilience. Found in high amounts within collagen and gelatine-rich foods, glycine is incredible for the body, aiding sleep, gut health, skin quality, and really helping joints withstand stress over time.

Best sources: Bone broth, gelatine, collagen powder, skin-on poultry, slow-cooked connective tissue.

4. Copper (Hardens collagen & elastin)

Copper activates the enzyme that hardens collagen and elastin, making your connective tissue strong and resilient. Without copper, connective tissue stays weak and prone to injury. It's highly important to get this naturally, as your copper and zinc ratio needs to be kept at a good level for optimal absorption and function.

Best sources: Liver, oysters, crab, heart, spleen, kidney, dark chocolate, egg yolks.

5. Vitamin C (collagen synthesis)

Vitamin C is absolutely essential for collagen synthesis and repair. No vitamin C means fragile joints. So many people turn to synthetic ascorbic acid thinking it's the same as vitamin C from food because that's what the label says, but it's really not. Whole-food vitamin C comes with cofactors that help your body actually use it.

Best sources: Oranges, clementines, acerola cherry, camu camu, bell peppers.

6. Sulphur (cartilage matrix strength)

Sulphur is found throughout connective tissue and is necessary for cartilage matrix strength and durability. It helps build the structural components that give cartilage its ability to withstand compression and maintain integrity under load.

Best sources: Eggs (especially yolks), red meat, organ meats, connective tissue, garlic, onions.

7. Hyaluronic Acid (joint lubrication)

Hyaluronic acid maintains synovial fluid thickness and joint lubrication, it's what keeps your joints moving smoothly without friction. Your body produces this naturally, but consuming foods that support its production helps maintain healthy, well-lubricated joints.

Best sources: Chicken feet (add to broths), fish skin, fish heads and eyeballs (add to broths), egg yolks.

8. Manganese (cartilage matrix formation)

Manganese plays a direct role in cartilage matrix and glycosaminoglycan formation, the gel-like compounds that give cartilage its shock-absorbing properties. It helps build the cushioning structure between your bones.

Best sources: Clams, mussels, macadamia nuts (also low in PUFAs), pineapple, birch water, dark chocolate, egg yolks.
