Foods and supplements claimed to help joints and bones

At a glance

54 foods and supplements marketed for joints and bones, each graded one by one against clinical trial evidence. Grade spread: B 2 · C 32 · D 13 · F 3. Only 2 reach grade A or B.

The grade measures how strong the evidence is, not how good something is for you. Grade A means independent research groups replicated a reduction in real clinical events in humans; grade F means well-designed trials established there is no effect. See Methodology.

Claimed to help joints and bones — strongest evidence first

Within a grade, higher scores come first; verdicts without a score sit at the bottom. Follow a name to see its trials, evidence, and limits.

Not swallowed — applied, inhaled, held in the mouth, worn, or performed on the body (8)

Same claims, but these are not taken by mouth: rubbed on the skin, breathed in, chewed or rinsed and spat out, worn on the body, or performed as a procedure such as acupuncture or cupping. A different route into the body, so they are listed separately.

Claimed to harm joints and bones (1)

Here a higher grade means the harm is better established — the opposite direction from the table above. A low grade means the claim of harm rests on weak evidence.

What does have evidence for joints and bones

Not foods or supplements: drugs and procedures graded A or B. Chamgap recommends nothing. It only shows where the evidence is strong. Any treatment decision belongs with your doctor.

How to read this list

A grade of C or D does not mean "do not take it." It means the evidence is not yet strong enough to promise the effect. Equally, A or B does not mean it works for everyone.

Chamgap sells nothing and takes no advertising. See all Joints & Bones verdicts.
