Unilever is rolling out Flora Pro-activ Buttery across the multiples after a successful exclusive four-week run in Sainsbury's.

Unilever hopes the product, which is churned from buttermilk but contains cholesterol-lowering plant sterols, will encourage more consumers to trade up into cholesterol-lowering products. "Buttery spreads is the fastest-growing segment in the category as taste is a key driver for consumers," said a Unilever spokesman.

Available now, Flora Pro-activ Buttery comes in a 500g pack (rsp: £4.25).
