Ocado and Amazon-listed health food brand Tree of Life has grown its annual sales by 10% to £50m in the year ending 31 March 2016.

The health and organic food supplier said these “record” sales were achieved “through the continued development of the company’s multi-channel strategy”.

It said it has continued to expand its operations with independent retailers during the year, while building new partnerships with mainstream bricks and mortar stores and online retailers.

Its own brand has also achieved major growth, with a 44 percent increase in sales during the year

Tree of Life plans to extend its range to 500 lines by the end of 2016, a 25% increase.

John Weaver, CEO of Tree of Life, pointed to growing knowledge about food allergies have helped grow consumer appetite for free-from products.

“While these recent trends are clearly a bonus for the traditional health food sector, we are seeing specific categories moving from advised sale sectors of health food stores and pharmacies into the mainstream grocery distribution,” he said.

“All classes of trade now have serious interest in these categories which are fast losing their ‘specialist’ status as they become a regular feature of consumers’ baskets.”

Tree of Life did not provide earnings figures in its financial update.

In the year to 31 March 2015 pre-tax profit for Tree of Life UK was up 0.9% to £803k on revenues of £41.4m.
