What is Liposomal Iron?

Iron is one of the hardest nutrients for the body to take up, and ordinary iron supplements are known for the discomfort they can cause. Liposomal Iron is built differently.

We wrap each particle of iron inside a microscopic sphere of lipids, the same building blocks that make up your own cell membranes. This lipid layer protects the iron as it moves through the digestive system and carries it in a form your body is designed to recognise. It is a smarter, more elegant way to take a notoriously difficult nutrient.

Every dose is paired with vitamin C, because vitamin C increases iron absorption. Together they make Liposomal Iron a genuinely considered piece of nutrition rather than another hard-to-tolerate iron pill.

Why take Liposomal Iron?

Iron sits at the centre of how your body makes energy and moves oxygen, and most people underestimate how much it does.

Iron contributes to normal energy-yielding metabolism and to the reduction of tiredness and fatigue, which makes it a natural first place to look when your energy feels flat. It supports the normal formation of red blood cells and haemoglobin and normal oxygen transport around the body. It also contributes to normal cognitive function and to the normal function of the immune system.

We add vitamin C to every dose for two reasons. Vitamin C increases iron absorption, so it helps your body make the most of every serving. It also contributes to the normal function of the immune system and to the reduction of tiredness and fatigue in its own right.

One considered daily dose, working with your body rather than against it.

Backed by clinical research

We do not take iron lightly, so we put our liposomal iron liquid through a randomised, double-blind, placebo-controlled clinical study, the most rigorous standard this kind of research has.

Over 30 days, our liquid was tested against both a standard non-liposomal iron and a placebo. The trial measured how well the iron was tolerated day to day, using abdominal comfort as a marker, because stomach upset is the single biggest reason people give up on iron.

The results were clear. The liposomal group reported significantly less abdominal discomfort than the group taking standard iron, and no abdominal pain was recorded in the liposomal group across the full study. It reflects the principle behind everything we make: better nutrition should never come at the cost of comfort.

Ingredients and info

Both formats deliver the same 100mg iron bisglycinate per serving, of which 20mg is elemental iron. The main difference is vitamin C: our liquid sachets carry a higher dose at 200mg per serving, while the capsules provide 40mg. Both pair iron with vitamin C because vitamin C increases iron absorption.

Reviews

Zooki iron tablets saved my life

"For so many years (best part of a decade) I was anaemic. I was getting iron infusions, tablets, everything. Up until I started on Zooki iron capsules in April 2024. I haven't needed anything else since. Long story short - 11 weeks ago, at the age of 41, I had a hysterectomy for extremely troublesome periods that I've been dealing with for 20 years. Blood tests in the months leading up to my surgery, my surgeon could not believe my iron levels were so good considering how much blood I was losing each and every month. I put that down to the iron capsules by Zooki - 100%. They have quite literally saved my life 🥰 and for that, I thank you. Anyway, I just wanted to say thank you. If you need proof that your products work, I'm it ❤"

Thumbs up for Iron Liposomal Capsules

"Bought these capsules for my husband who had been diagnosed with low iron. We're both vegan! He's just been for another blood test and levels are back to normal! These have done the trick and caused no constipation, which can very often happen with iron supplements. Highly recommend. Zooki cones out on top yet again!"
