What the reviews found
Supplements for Bone Health
6 where systematic reviews concluded a benefit, 2 with mixed findings, 3 where they concluded no effect. Every line quotes the review and links it, so you can read the sentence yourself.
Reviews found a benefit
Systematic reviews concluded these improve an outcome tied to bone health, and none concluded no effect.

Reviews found no effect
Reviews studied these for an outcome tied to bone health and concluded they made no difference.
- Bacillus subtilis1 review citedNo effectbone mineral density
“Effects of probiotic interventions on BMD were inconsistent, with the majority of studies demonstrating no benefit at the spine or hip.” PMID 34748440
- 1 review citedNo effectgrowth and fractures

Not enough to say
Reviews of Bifidobacterium longum, Creatine, DHEA, Potassium could not conclude either way on bone health.
How this page is built
Each finding is the conclusion a set of systematic reviews reached on one outcome — whether an ingredient helped, made no difference, or could not be judged — with a sentence quoted from one review, checked to appear in its PubMed abstract. It records the direction, not the size, of an effect. Reviews run in populations such as people with cancer, pregnancy, surgery or children are left out, because applying them to a general reader would mislead. Evidence last refreshed September 2026.

Other goals
Educational only. A review finding a benefit on average does not mean a supplement will help you, or that it is safe alongside your medication. If you are treated for bone health, talk to your clinician before adding anything.
