Product Details

Zahler Iron Complex is a thoughtfully formulated iron supplement for men and women who want reliable daily iron support without the digestive discomfort that puts so many people off taking iron tablets regularly. At the heart of this formula is Ferrochel, a premium chelated iron that is far easier on the stomach than the standard ferrous sulphate found in most iron supplements on the market.

What makes it work:

  • Iron as Ferrochel (Ferrous Bisglycinate Chelate) 25 mg, a highly bioavailable form of gentle iron that absorbs efficiently and is specifically designed to avoid the constipation and stomach upset commonly associated with standard iron supplements
  • Folate as L-5-Methyltetrahydrofolate Calcium 400 mcg DFE, the active methylated form of folate the body can use straight away, supporting healthy red blood cell formation and haemoglobin production
  • Vitamin B12 as Methylcobalamin 80 mcg, a highly absorbable form of B12 that works alongside iron and folate to support complete blood-building nutrition
  • Vitamin C as Ascorbic Acid 60 mg, included to enhance iron absorption and provide antioxidant support
  • L-Histidine as L-Histidine HCl 100 mg, an amino acid that plays a supporting role in iron transport within the body

Why so many people switch to this iron formula:

Standard iron tablets are notorious for causing constipation, nausea and stomach cramps. These side effects are so common that a large number of people simply stop taking their iron supplement entirely. Zahler Iron Complex takes a different approach. By using Ferrochel, a chelated iron that is absorbed more efficiently and sits comfortably in the digestive system, this formula delivers the iron your body needs without making you dread taking it every morning. Easy on the stomach, effective and consistent.

What you get in every bottle:

  • 100 capsules per bottle, 100 full servings
  • Kosher Certified and Halal Approved
  • Vegetarian friendly, non-GMO, gluten free, dairy free, soy free, peanut free and egg free
  • GMP certified facility
  • Clean formula with no unnecessary fillers

A complete gentle iron supplement with Ferrochel, methylated B12 and folate for comprehensive and comfortable daily iron support.

How to Use
+ -

Recommended dose:
Take 1 iron capsule daily with food and water.

Tips for best results:

  • Take consistently every day with meals for comfortable and effective iron absorption
  • Taking alongside a vitamin C rich food or drink can further support iron uptake
  • Avoid taking at the same time as dairy, caffeine or antacids as these can reduce iron absorption

Important safety information:

  • Do not exceed the recommended daily intake of this iron supplement
  • Pregnant or breastfeeding women should consult their GP before use
  • Not recommended for children under 18 without medical advice
  • If you have a known medical condition, iron deficiency or take prescribed medication, speak to your GP before starting any new iron supplement
  • Keep out of reach of children
  • Store in a cool, dry place away from direct sunlight

High iron absorbency rate needed to help my anemia/improve my energy levels. Works GREAT!

Wow, these are so far the best overall iron supplements I have used, and I’ve tried MANY different brands/types, etc.Increasing your iron to get your levels above anemic levels takes time, and I’ve learned that the most important thing is finding a type/brand that allows your body to absorb. These may only be 25 mg, compared to some 67 mg, and 100+ mg brands that I used, however, of all the brands I tried, these have positively affected my anemia for the positive the best. In addition, they include other vitamins I need, C and D. Since starting to take these about a month ago, I started feeling more energy after about 2 weeks. It still appears to be getting better, but I expect it to be slow. Very easy to swallow (tasteless capsules) and no aftertaste. One type is used to take made me throw up once in a while, and I know it was the pills, because I could taste it.I’ll post again in a few months and hopefully these will do the job and get me back up in the teens again and energized. Thanks!

Great no-side effect Iron Supplement.

I have been using Zahler brand Iron Complex with vitamins since 2017. I began taking these when I was no longer permitted to donate blood because my iron levels dipped below their minimums. I was looking for a lower dose to minimize side-effects (if you know what I mean).I can attest that not only do these supplements increase your blood's iron levels, they do it without upsetting your stomach and without constipation.In 8 years, I have never questioned to quality of this product.

I have been taking this iron supplement for years after it was recommended by my doctor. I had suffered from iron deficiency anemia for years. even requiring iron transfusions at the hospital until I began using this product. It has been fantastic, and my iron levels have been back to normal due to using this product. I would highly recommend it!!!

Increased iron count

I bought this when my husband who had to have an iron infusion to increase his iron at one point had his iron count began to drop again. It worked really well for increasing his iron count and I've continued to buy it for several years. His current blood specialist doesn't recognize this brand and has switched him to a different one. If I don't see the same improvement I will be switching him back to this one. I've used this product myself after a surgery when I had low iron counts a and it got me back to a normal level better than the product the Dr had suggested. I really like Zahlers, it had no bad after taste, and did not have the constipation issues common with iron supplements. I feel it is a good product, the current specialist said she will check out it as she'd never heard of it.

Excellent absorption

I have ben buying Zahler Iron Complex for 3 or 4 years. I was told by my primary care physician that iron pills could help my restless leg syndrome - and I chose Zahler Iron Complex for its purity and additional supplements that support healthy blood and the absorption of the iron. Very pleased with the product!

Great Iron Capsules

Several years ago I was feeling tired and sluggish. As I am over 60, I knew that I needed to supplement my diet with iron. I found these capsules on Amazon and almost immediately I could feel the difference. They are easy to take and easy on my stomach and have never been constipating. Now they are part of my monthly vitamin order. I would highly recommend them.

Highly recommend for vegetarian women

As a 30+ year vegetarian woman I highly recommend Zahler’s Iron Complex. I have been taking this supplement for years and attribute my normal labs to taking it daily. Waaaaaay back I treated anemia with Nifrex and this product is far superior! I have no stomach issue and zero constipation while taking this supplement. It also smells like absolutely nothing which iron often struggles with. As an OTC it is amazingly priced for all it contains (Vit C, Folate, B12, Iron as Ferrous Bisglycinate Chelate, and L-Histidine). Thank you Zahler’s for creating such an amazing product! It really has increased my quality of life!

Will buy again!

As somebody is struggling with a ferriten deficiency, having trouble absorbing iron, these have been amazing. The mix of vitamin C with iron has really helped me absorb it, and I have not had any unpleasant side effects. I love this brand and will keep buying!!!
