Called Discover Your Strengths, the push will include an on-pack promotion giving consumers the chance to win one of eight places on an activity holiday on Stength Island - the Petit St Vincent resort in the Grenadines, a group of islands in Caribbean.
The winners will be joined by TV sports presenter Kirsty Gallacher and former England cricketer Mark Ramprakash
and they will take part in activities to build mental and physical strength.
To enter the competition
participants must enter a code - that can be found on cartons and bottles of AdeZ -
via www.adez.com. Shoppers can also take part in a one-to-one strength session with either a nutritionist, a personal trainer or a life coach by collecting three individual codes. Unilever
will introduce a 25cl bottle to its AdeZ range in a move to target "on the go" consumers, according to a spokeswoman. Mango & Apricot and Blackcurrant & Raspberry will be available in the new bottle sizes from mid-June.
