It marks the first time that Nature's Range, which produces products such as Jointease to help people with osteo-arthritis and Prostease aimed at men with prostate problems, has made its database available to the marketplace.
The list is compiled from those who have responded to direct mail, with the vast majority being over 45 years of age and in the AB demographic with high disposable incomes.
As well as postal addresses, telephone numbers are also available to rent from the database, making it suitable for telemarketing campaigns.
Lindsay Johnson, managing director at Avongate, said: "It's a database that presents a wealth of opportunities for marketers, particularly those aiming to recruit donors for charities as well as those looming to successfully target the over 50s. It also offers great opportunities to marketers in the health, home shopping and finance marketplaces."
