How Long Does It Take Iron Pills to Take Effect and What Does That Mean?
If you were to Google “How long does it take for iron supplements to work?” you’ll mostly find specific answers like 2 weeks or 2 months. All of these may be true – because many factors come into play when determining when you should take iron, how iron is absorbed in your body, and how much iron you need. That’s why today, we’ll examine each of them so you can make clearer, more informed decisions and achieve the results you’re looking for. To start, let’s make a differentiation between how long it takes for iron to actually “work” and how long it takes for your body to “absorb” iron.
How Long Does Iron Take to Get into your System After Taking Iron?
How long it takes for iron to get into your system depends largely on:
(1) Why your levels were low in the first place and
(2) How far below the normal they were. The lower your current level, the longer it will take to build up a sufficient amount of iron in your system.
Consider the following cases:
- If you need more iron because of menstruation, it will usually take a bit longer to build up because you’ll continue to experience blood loss with every period.
- If your dietary intake of iron is insufficient, it may replenish very quickly if your supplement allows you to absorb it better.
- If you change your current dietary habits to focus more on rich sources of iron, it might still take a while to get your iron levels back to normal.
The Most Important Factors to Consider when Taking an Iron Supplement
Your Current Diet and Nutritional Habits
An iron-rich diet can be challenging to sustain, especially if you need to build up a significant amount of iron. In this section, we are going to look at foods that decrease iron absorption, as well as foods that increase iron absorption.
Foods That Decrease Iron Absorption
Some foods and nutrients are natural iron inhibitors – they diminish the absorption of iron and make it difficult for you to reach optimal levels. These foods/nutrients include:
- Phytic acid (often found in grains and legumes)
- Tannins
- Polyphenols (found in tea)
- Milk
- Caffeine
- Some of the proteins found in soybeans
(And, considering many people’s days start with a cup of coffee or a bowl of milk and cereal, we can quickly begin to see why iron absorption is a challenge.)
Foods That Increase Iron Absorption
On the flip side, other foods are known for increasing your iron absorption, and they are often recommended to be taken alongside iron supplements. These include:
- Citrus items and citric acid – lemons, lemonade, oranges, orange juice
- Vitamin C
- Vitamin A and beta-carotene
- Beef
- Meats, fish, and poultry
How Soon After Taking Iron Supplements Will I Feel Better?
It can take anywhere from 3 to 12 weeks to feel better after taking iron supplements. For example, Active Iron is clinically proven to increase iron and energy levels in six weeks, but many report seeing an increase in their energy levels after three weeks.
In all cases, if you suspect you need more iron, the best approach is to talk to a professional who can guide you and help you figure out the reasons you might not be feeling well and if iron is a factor in you feeling tired or fatigued. From there, they can guide you on whether iron supplements will help you feel better or not.
Some Iron FAQs From Customers:
How Quickly Do Iron Supplements Work?
Haemoglobin blood levels generally increase after 2 to 4 weeks of supplementation. Symptoms like fatigue, weakness, and headache should start to improve during this time. It typically requires around three months for iron stores (measured by ferritin levels) to reach a normal level.
How Long Should I Take Iron Supplements For?
Iron supplements should be taken for at least 6 months and up to 12 months. The best way to ensure adequate absorption is to take them on an empty stomach or allow 2 to 3 hours between meals as certain food, drink and medicines may inhibit iron absorption.
How Long Does It Take To Get Iron Levels Up?
Active Iron is clinically proven to increase iron levels by 94% in 6 weeks, but many start to feel the benefits earlier than that.
How Long Does It Take For Iron Levels To Drop?
Your body uses about 500mg of iron to make about 2g/dl of haemoglobin, which is a protein in your red blood cells that carries oxygen. We require extra iron to create energy and for our body to function correctly.
When we stop taking iron, the body uses internal reserves of iron. The drop in iron levels will depend on our diet and way of life. For example, if you like doing endurance sports your iron levels could fall quicker. As iron levels fall below the standard range, you may notice fatigue, headaches, and eat less.
How Long Does It Take To Raise Iron Levels With Food?
This is something that is quite complicated to measure, considering everyone has different health needs. It is difficult to raise iron levels with food alone, especially for vegetarians and vegans etc. We do recommend taking an iron supplement as well as eating food that is rich in iron to increase your iron levels.
Enjoy The Benefits Of Active Iron

“I’m a very active person , my iron levels seem to drop quite quickly. This iron product keeps my iron levels stable. I don’t have any issues with my stomach or with constipation. Would recommend this product, it’s gentle.” – Lorraine G A
“I was getting very ill and thinking it was something serious, resting heart rate 148, out of breath, felt like I was stroking some days. It turned out that I was anaemic. I tried supermarket iron tablets, and they made me ill. I’ve seen these on the web and thought I would try these for size. Some people say it takes a good 3 months to get back to a good level, but you can tell after a couple of weeks that things are progressing. I am seriously feeling better, will keep taking these.” – William Mcinally
“It’s easy to swallow and, more importantly, it does not make you constipated. It’s highly efficient as my iron levels are back to normal after just three weeks.” – Mme. T.M. Ayoub
