Chia seed brand Chia Bia has launched a range of gluten-free biscuits into Tesco.

Chia Crunch comes in four flavours: chocolate chip, ginger, blueberry & almond and lemon (rsp: £2.99/ 12-pack) and will be stocked in 77 stores.

Tesco will also stock packs of loose Chia Bia chia seeds in four variants: whole, milled, milled with cranberry and milled with blueberry (rsp: £3.99/100g).

Demand for chia products had doubled each year since Chia Bia was founded in 2009, said co-founder Ray Owens.
