Lipofer® (Microencapsulated Iron — Lubrizol)

Evidence Level
Limited
1 Clinical Trial
3 Documented Benefits
2/5 Evidence Score

Lipofer® is a microencapsulated iron from Lubrizol Life Science, in which iron is coated in a protective matrix. The encapsulation is designed to improve tolerability and absorption, reducing the metallic taste and digestive upset that often come with ordinary iron, while still correcting iron needs.

Studied Dose Providing a typical supplemental iron dose, often around 14 to 18 mg per day.
Active Compound Microencapsulated iron (ferric pyrophosphate) coated in a protective lipid-and-matrix shell for better tolerability and absorption.

Benefits

Iron support with better tolerance

Microencapsulation reduces the stomach upset, constipation, and metallic taste that make ordinary iron hard to take, supporting consistent use.

Supported by Trial 1

Energy and oxygen transport

Iron is essential for making hemoglobin, which carries oxygen, so correcting iron needs supports energy and reduces fatigue.

Supported by Trial 1

Suitable for fortification

Its neutral taste and stability make it useful in foods, drinks, and supplements, including for women and others prone to low iron.

Supported by Trial 1

Mechanism of action

1

Protected delivery

The encapsulation shields the iron from interacting with food and the gut lining until it is absorbed, lowering side effects and oxidative reactions.

2

Hemoglobin synthesis

Absorbed iron is used to build hemoglobin and myoglobin, supporting oxygen transport and energy metabolism.

Clinical trials

1
Microencapsulated Iron Bioavailability — Study
PubMed

Comparative study of the effects of different iron sources on bioavailability and tolerability. (Marine-Casado et al. 2025, Scientific Reports)

Comparative model study.

The microencapsulated iron showed favorable absorption characteristics relative to other iron sources, supporting its tolerability advantage.

Side effects and drug interactions

Common Potential side effects

GENERALLY BETTER TOLERATED than standard iron salts.
Some digestive upset or constipation can still occur.
Iron can be dangerous in overdose; keep away from children.

Important Drug interactions

Thyroid medication and certain antibiotics — iron reduces their absorption; separate by several hours.
Antacids and calcium — reduce iron absorption; separate dosing.
Do not take extra iron unless you need it; confirm with a blood test.
