Osteoguard Advance is an all in one bone health formula providing 250mg of magnesium and 500mg of calcium per two tablets. The magnesium is in the form of a unique blend of three different magnesium compounds - citrate, hydroxide and carbonate, plus the calcium as both carbonate and citrate.

Where this comes from

The part other shops don't tell you. Three separate questions, kept separate on purpose, each with its source.

UK company
Registered at Companies House as LAMBERTS HEALTHCARE LIMITED, number 04500877. Checked 2026-08-29.
Means the business is a British legal entity, not a British-sounding name owned elsewhere. It says nothing about where anything is made.
UK operations
Stated by the company: "Although we are based in Tunbridge Wells, our products are not just confined to the UK; we despatch to practitioners in over 39 countries around the world." Source.
Means people employed here, or premises they actually work from. We keep this separate from the company badge because a registered office can be an accountant's spare room, and a company can be registered in Britain while everything it does happens somewhere else. Where we have not looked, we say so rather than assuming.
British-owned
No majority shareholding traced outside the UK. Companies House.
Read from the register of people with significant control, following the chain of holding companies. It does not gate anything: a firm can be made here and owned elsewhere, and that is worth telling you rather than hiding.
Where it is made
The maker doesn't say, so neither do we.
This is about the individual product, not the company. A British firm can sell things made abroad, which is normal and not a criticism. We would rather tell you which is which than average them into a score.
