The free-of-charge magazine, which has a distribution of 1.5 million copies, will be circulated to GPs' surgeries and Citizens Advice Bureaux, as well as at various related events from the start of November.
August Media says the magazine, which will be produced on a fee rather than ad-funded basis, will have a new look and provide an insight into the up-to-date health information that is available for free at the Department of Health's website NHS.uk.
One key aim of the magazine will be to shift the perception of the NHS from a service for illness to one of prevention and wellbeing.
The magazine, which was previously published twice a year, is now expected to increase frequency and become a quarterly title.
The win marks the first foray by August Media into the NHS and complements its existing portfolio of titles including IKEA Family Live and Butlins.
Mark Lonergan, managing director of August Media, claims the magazine will help encourage people to be active and "take responsibility for their health and wellbeing".
Earlier this year, August Media, which was set up in 2005 by former Cabal Communications executives Lonergan, Sarah Bravo and Jules Rogers, boosted its commercial presence by the appointment of Katherine Punch, who took on the role of commercial manager, and Kitty Finstad, who was appointed as group editor working across clients including Butlins.
In Febraury, CALA Homes, a premium housebuilder, appointed August Media to rebrand Exclusive, its customer magazine. The title is aimed at current and prospective CALA Homes customers.
