What are the benefits of liquid iron?

Most of us get enough iron from dietary sources. However, some people choose to take iron supplements to increase their intake. These may include pregnant women, athletes, vegetarians, and vegans.

Iron supplements have a long history, with the first recorded use of iron supplements all the way back in the nineteenth century. Things have come a long way since then; however, some still people experience problems with traditional iron supplements. These include nausea, vomiting and stomach pain.

Liquid iron supplements were developed as an alternative for people who are intolerant of traditional iron supplements, under the assertion that liquid iron is more easily absorbed by the body.

How quickly do liquid iron supplements work?

The length of time it takes for liquid iron supplements to work will vary from person to person. Some people feel the benefits straight away, while others take much longer, up to several months.

Many issues affect how quickly the liquid iron is absorbed in the stomach.  Factors such when in day you take the supplement can have an impact. Some foods can also help increase iron absorption, while others have a negative effect.

Is liquid iron absorbed better?

The absorption of liquid iron supplements depends on a range of factors, including when and how you take liquid iron. The best time to take liquid iron is in the morning on an empty stomach. However, this can make side effects such as nausea and constipation much worse.

It’s also worth noting that manufacturers generally make liquid iron supplements in low concentrations. This is to prevent accidental overdose in children, who may try and drink liquid iron if left unsupervised.

Poorly absorbed iron supplements can lead to gut irritation, including constipation and nausea. Iron gets absorbed in the duodenum which is in the small intestine. The best iron supplement to use is one that’s released at the body’s natural site of absorption.
