Can you sell colostrum?

The first milk is measured in teaspoons, matters more per drop than anything else you will ever make, and comes wrapped in the internet's most confused answers – most of which turn out to be about cows. This is the human version, told straight.

What colostrum is, and why the numbers around it are so odd

Colostrum is the first milk – made in late pregnancy and the first few days after birth, thick and deep yellow, so prized on postnatal wards that midwives call it "liquid gold". It is concentrated in a way mature milk never is: dense with antibodies and protective proteins, produced in amounts that match a brand-new stomach. First feeds are measured in millilitres, not ounces. Over the first days it gives way to transitional and then mature milk, and the window closes.

Everything strange about the colostrum question follows from that arithmetic. It is the most concentrated milk there is, made in the smallest amounts, for the shortest time, for the person who needs it most.

Your baby's claim comes first, and it is the whole batch

Everywhere else on this site, the milk under discussion is a genuine surplus – freezer bags a baby was never going to drink. Colostrum has no surplus by default. The whole of what you make in those first days is roughly one newborn's ration, and the newborn is in the room. If your baby is here and feeding, the colostrum is spoken for, and there is nothing further to weigh.

The one honest exception is small: syringes collected before the birth on a midwife's plan that your baby turned out not to need. Those amounts are tiny, they were collected for a purpose, and the right person to ask about them is the midwife who set the plan – not a marketplace. A freezer full of mature milk can be an opportunity. A drawer of colostrum syringes is a plan that worked out differently, and it deserves a different conversation.

The cow confusion: why the internet thinks this is illegal

Search "is it illegal to sell colostrum" and you land in dairy law. US state dairy codes regulate the sale of "colostrum milk" from cattle – Washington, to take a real example, barred it for human consumption outright until a 2000 bill created a route for processed bovine colostrum as a supplement. Rules like these read alarmingly in a search result and have nothing to do with you. They are about herds.

Human colostrum is human milk in the eyes of food law: legal to sell in the UK and the US, with the same duty for regular UK sellers to register as a home food business, and the same expectation that it is handled and described honestly. There is no special colostrum offence. What you found was a rule about cows.

Who actually buys colostrum – three lanes, honestly

The supplement aisle is not buying yours. The colostrum in wellness powders and capsules – a booming trade at the moment – is bovine, collected from dairy cows and processed at industrial scale. A buyer who wants "colostrum" for a smoothie is looking for a cow product with a label on it, and nothing a mother can pump will meet that order.

The research market is real, and mostly closed. Laboratory suppliers list single-donor human colostrum for research use at prices that stop you mid-scroll – one US supplier lists a single millilitre at $215. But those catalogues do not publish how they source it, there is no counter where a mother hands over syringes, and the paid programmes that do take individual donors – at about a dollar an ounce, roughly $3.40 per 100 ml – buy mature milk, not colostrum. The gap between those two numbers is the true shape of this market: the price is real, and the route to it, for one mother with a few syringes, mostly is not. Writing to a supplier costs nothing; expect a no.

Peer buyers exist, but barely. Demand on the family side is for feeding babies, and the rare buyer genuinely seeking early milk is usually an adoptive or surrogacy family with a newborn – tiny volumes, syringes, dated, and shipped frozen with the same care as any other milk. Adults asking for colostrum for themselves are usually reaching for the supplement trend by other means: we make no health claims for adult use of any human milk, colostrum included, and a seller's audience setting applies here as everywhere.

Expressing before birth – read this even if you skip the rest

Antenatal colostrum harvesting is a real, NHS-taught practice: hand-expressing only – no pump before birth – from about 36 to 37 weeks, taught by your midwife, and useful where a plan for the first feeds helps. It is also specifically not advised in some pregnancies, which is exactly why it is midwife-led from the first conversation.

We bring it up to close a door plainly. Harvesting is a plan for your baby's first days. It is not a production method, and this page must not give a pregnant reader ideas in that direction: collected colostrum belongs with the plan it was collected for, and whether to harvest at all is a question for your midwife appointment, not for a marketplace.
