We sold out.
We're coming back better.

Your payment is taken when you place your pre-order. This reserves your box from the November production run and guarantees priority dispatch.

Yes. isomum was formulated by a specialist midwife to be safe and supportive across all trimesters, during labour and birth, and throughout postpartum and breastfeeding.

Two reasons. First, we added a little sugar, about half a teaspoon per sachet. The lining of your gut has special doorways that only open for salt and sugar together. That's how your body is built, so we built the formula around it, not around a "zero sugar" trend. Second, we took out the vitamins. Most women are already taking a prenatal, and we wanted you to be able to take ISOMUM alongside yours without wondering whether you're doubling up.

Electrolytes are minerals like sodium, potassium and magnesium that carry a tiny electrical charge in your body. Your body uses them every day to manage fluid and keep your muscles and nerves working normally. Most of the time, a varied diet gives you everything you need, and nobody needs an electrolyte drink with every meal. But there are stretches of life when eating and drinking well gets harder: morning sickness, a long labour, hot weather, or broken nights with a newborn. That's when getting what you need from food alone isn't always realistic, and an electrolyte drink can help fill the gap. Magnesium, for example, contributes to the reduction of tiredness and fatigue. If sickness in pregnancy means you can't keep food or fluids down, speak to your midwife or GP. That needs proper care, not a sachet.

It sold out after our UK StartUp Awards win, which was a nice problem to have. Raspberry Lemonade takes its place for now: brighter, fresher, and in a box too good to hide in the cupboard. The original flavour is back in the new year, in the new formula and the new look.
