Answer

dear Gareth
you may want to take a look at the Enterprise Europe Network website, www.enterprise-europe.co.uk, which offers a free partnering service to match you with European trade partners.
you can do a keyword search, e.g. supplements and look for Commercial Requests.
for instance: https://www.enterprise-europe.co.uk/content/search/profile-detail/?techref=brro20151120001
and https://www.enterprise-europe.co.uk/content/search/profile-detail/?TechRef=BRPL20141216001

You can set up automatic alerts to receive emails with a list of new profiles added that match your criteria.
You can also contact your local EEN team via the website.
I hope this is useful

Hi Gareth,
If I were you I would contact CLF here in the UK ( google CLF Healthfood Wholesale),as they specialise in UK and European distribution. They are probably the biggest here in the UK.

Another company I currently use for one of my clients is The Health Store in Nottingham. They are a very big UK Wholesaler and may help you with Europe.

Good Luck
Steve
