Everything you need to know
about freeze-drying your milk

We know it sounds like science — and it is — but it's also beautifully simple. Here's everything you need to know, in plain language.

What Is It?

So, what exactly is freeze drying?

Freeze drying is a gentle preservation process used in hospitals, science labs, and even space food. It removes the water from your breast milk — without using heat — leaving behind all the good stuff: the nutrients, antibodies, and immune factors that make your milk so special.

Think of it like this: your milk is frozen solid, then placed in a vacuum chamber. The ice turns directly into vapour and is drawn out, leaving behind a fine, shelf-stable powder that is 100% your milk — just without the water.

When you're ready to use it, simply add water back and it rehydrates within seconds. No nutrients lost. No heat. No nasties added.

Nutrients Stay Intact

Because no heat is used, the delicate proteins, live antibodies, enzymes, and immune factors in your milk are preserved exactly as nature made them. Studies show freeze drying retains significantly more bioactive components than any other preservation method.

98%+ Nutrient retention

Up to 3 Years Shelf Life

Once freeze-dried, your milk powder can be stored at room temperature for up to 3 years — no freezer required. It's ideal for travel, returning to work, building an emergency supply, or simply having flexibility in how and when you feed your baby.

3 Years Shelf stable storage

Lightweight & Convenient

Water makes up around 87% of breast milk's weight. Without it, your milk becomes a lightweight powder that's easy to store, travel with, and portion out precisely. One jar of powder can represent many feeds — easy to take anywhere.
