Natural Iron, Naturally
Iron support that just cooks.
Drop IronFin into any soup, stew, or pot of water and let it simmer. One reusable piece of food-grade cast iron, thousands of meals, no pills, no taste, no subscriptions.
Why IronFin
One small drop. A lifetime of use.
Designed for real kitchens — not another pill to remember.
Reusable, not refillable
One IronFin is built to last for years of daily use — no repeat purchases, no subscriptions.
Zero taste, zero fuss
Simmer it in soup, stew, rice, or water — it works quietly in the background of meals you already cook.
Food-grade cast iron
Made from the same material as traditional cast iron cookware — no coatings, no additives.
Built for real life
A simple swap for anyone mindful of their iron intake — vegans, busy parents, and home cooks alike.
How It Works
Three steps. Every day.
Drop it in
Add IronFin to any pot of boiling water, soup, stew, or sauce — no prep required.
Simmer for 10+ minutes
Let it sit in the heat as you cook. The longer it simmers, the more it does its job.
Rinse, store, repeat
Remove it, give it a rinse, and it's ready to go again tomorrow. That's the whole routine.

FAQ
Good to know
What is IronFin made of? +
IronFin is made from food-grade cast iron — the same material used in traditional cast iron cookware, with no coatings or additives.
How long does one IronFin last? +
With daily use, a single IronFin is designed to last several years before it needs replacing.
Is it safe to use during pregnancy? +
IronFin is a cooking tool, not a medicine or supplement. As with any change to diet or iron intake during pregnancy, we recommend speaking with your GP or midwife first.
How do I clean and store it? +
Rinse with water and pat dry after each use. Avoid soap, as it can strip the natural seasoning that builds up over time.
Where do you deliver? +
