Supplements or diet: what actually helps your joints?

By Mr Amit Kumar, Consultant Orthopaedic Surgeon · 4 min read

Should you reach for supplements, or focus on your diet, to look after your joints? It is one of the most common questions patients ask. The honest answer is that it is a combination, and some things matter more than others.

Anti-inflammatory foods

There is good evidence that eating oily fish can benefit your joints. Anti-inflammatory foods are a sensible foundation, and they support your overall health at the same time.

Weight makes a real difference

Optimising your weight is one of the most effective things you can do for your joints, and the numbers are striking.

Diet
Plays a major role in weight

Losing just 5kg of weight takes around 20kg of pressure off your joints. Diet plays a significant role in managing your weight, which is why food matters on two fronts: what you eat, and how it affects the load on your joints.

The supplement question

Supplements are the most debated part of joint health. Some patients swear by cod liver oil tablets, chondroitin, or glucosamine. The logic is reasonable, these are key components of cartilage, so the theory is that supplementing them supports it.

"There is mixed evidence on supplements. We do not actually know how effective they are."

So while they may help some people, the evidence is not clear, and they are not a substitute for the things that do make a measurable difference.

Do not forget lifestyle

Lifestyle changes can also maintain and support your joints. It is not just diet, and it is not just supplements. Staying active within sensible limits, managing your weight, and eating well all work together.

In short

Looking after your joints is a combination. Anti-inflammatory foods such as oily fish help, and managing your weight makes a real difference: losing 5kg removes about 20kg of pressure from your joints. Supplements have mixed evidence, so they are worth a try for some, but not a replacement for diet, weight, and lifestyle.
