Supplements for bone health
Vitamin D3 K2, calcium and magnesium, vitamin K2 MK-7, magnesium and OsteoAid: the authorised claims for bones, and what nothing here does.
How to choose a bone health supplement
Nothing on this page treats osteoporosis, and the page says so. Calcium, vitamin D, magnesium and vitamin K contribute to the maintenance of normal bones, which is the claim the evidence supports.
Why these
Vitamin D3 & K2: Vitamin D contributes to normal absorption of calcium and the maintenance of normal bones.
Calcium & Magnesium Citrate Malate Capsules: Calcium and magnesium contribute to the maintenance of normal bones.
Vitamin K2: Vitamin K2 as MK-7; vitamin K contributes to the maintenance of normal bones.
Magnesium Bisglycinate Capsules: Magnesium contributes to the maintenance of normal bones.
OsteoAid Capsules: The bone formula, with what it contains stated.
What to skip
Calcium on its own at high doses, which the trials do not support, and anything promising to reverse bone loss.

Common questions
Does anything on this page treat osteoporosis?
No. Calcium, vitamin D, magnesium and vitamin K contribute to the maintenance of normal bones, which is the authorised claim. Osteoporosis is diagnosed and managed by your GP.
Should I take calcium on its own?
High-dose calcium alone is not supported by the trials; the products here pair it with vitamin D and magnesium.
Why vitamin K2 with vitamin D?
Vitamin K contributes to the maintenance of normal bones and normal blood clotting; the two are commonly taken together, and the K2 product states its form as MK-7.
