Best magnesium for women in the UK

For most women a magnesium glycinate or citrate is the sensible starting point, as both are commonly chosen for being gentle on the stomach, with a topical spray as an alternative for those who dislike tablets. Below we compare named UK brands on form, who each suits and value. Magnesium is a supplement, not a treatment, so check with your GP or pharmacist if you take other medication.

How we compared

Our methodology is simple and disclosed. We shortlist real UK supplement brands across the common magnesium forms, then compare them on form, who each suits and value for money. We do not rank by affiliate commission, and we do not accept payment for a favourable placing. Where a buying link is not yet live, the link is marked as pending rather than guessed.

Frequently asked questions

What is the best magnesium for women?

There is no single best for everyone. Glycinate (bisglycinate) and citrate forms are commonly chosen for being gentle on the stomach, while a topical spray suits those who dislike tablets. The best choice depends on tolerance, format preference and budget.

How did you choose these?

We shortlisted real UK supplement brands across the common magnesium forms, then compared them on form, who each suits and value. We do not rank by commission, and we add a buying link only once it is live. See our methodology below.

Is more expensive magnesium better?

Not necessarily. A reputable glycinate or citrate with a clear elemental-magnesium amount per serving can be good value. Price often reflects brand and format rather than a difference in the magnesium itself.

Can I take magnesium with other supplements?

Usually, but some combinations and medications interact. If you take other supplements or prescribed medicines, or have kidney problems, check with your GP or pharmacist before starting.
