Grow with Iris: plant-based growing-up drink for children with food allergies

Grow with Iris is a British infant nutrition company that sells a fortified powdered milk alternative, formulated specifically for children aged 12 months to 4 years. The product is designed for little ones who cannot consume cow's milk or soya, and can also be enjoyed by older children. The company was founded by mothers with direct experience of food allergies and develops its formulas with advice from paediatric dietitians.

Composition and nutritional profile

The drink combines pea protein and coconut. According to the company, it provides 16 essential vitamins and minerals, including calcium, iodine, iron, zinc, folic acid and vitamins C, D, B12, B2, E and K. It is also a source of protein and fibre. The formula contains no stabilisers, preservatives, emulsifiers, genetically modified organisms (GMOs) or palm oil, and uses only natural flavours.

Allergens and risk management

The product is presented as free from milk, lactose, egg, soya, gluten, peanuts and tree nuts. The company states that it applies a rigorous allergen management protocol and that the formula is free from artificial colours, chemical contaminants, heavy metals and pesticides.

Formats and preparation

The range includes single-serve sachets (2 and 8 packs), a single pouch and a 6-pouch pack. The single pouch contains 540 g and provides 18 servings; the 6 pack contains 108 servings in total. Preparation simply involves adding water, and it can be enjoyed warm or cold. The company recommends one or two servings per day and notes that the format is travel-friendly. The catalogue shows the following prices: 6-pouch pack at £149.99, single pouch at £27.99 and 2-pack of single-serve sachets at £3.99. Delivery is free on orders over £100.

Advisory team and origins of the project

The company has a team of experts including allergy and respiratory paediatrician Dr Diab Haddad, paediatric dietitian Sarah Foster and sustainability expert Matt Fishwick. The project was inspired by Iris, the daughter of one of the co-founders, and arose from the difficulty of finding safe and nutritious options for children with food allergies.

Sustainability and recognition

Grow with Iris states that it has carried out two Life Cycle Assessments with experts, which according to the company demonstrate a lower environmental impact than dairy and plant-based competitors. The company attributes an 86% reduction in impact to the powder format, which avoids transporting water, together with lightweight, recyclable packaging. The company also states that it does not test on animals, is non-GMO and has obtained an ethical score of 98% awarded by the Good Shopping Guide. The product received a Gold award at the Free From Food Awards 2025.
