What ingredients to look for in good supplements for iron deficiency and better absorption?
Effect on iron levels - it is worthwhile to ensure proper iron absorption. Substances such as lactoferrin and vitamin C facilitate the absorption of iron into the body. When the deficiency is severe, medication will be necessary, but if the problem is minor, simply improving iron absorption from food can have great results.
Efficiency - the product should be efficient enough to last a long time, reducing the frequency of buying new packs.
Easeof use - supplementation should be convenient so that it is easier to maintain regularity. It is better to choose a product that requires taking two capsules a day than one that needs to be taken four times a day.
Capsule/tablet size - they need to be small enough to be easily swallowed, making them more comfortable to take.
Reputable manufacturer - choosing a supplement from a recognised manufacturer guarantees a high quality and safe product, which is confirmed by certificates and positive user reviews.
Take a look at our ranking of the best supplements for iron deficiency and absorption:
Lactoferrin by Nutridome, designed to support iron absorption, digestion and immunity. It is a dietary supplement with a simple but effective formulation, free from unnecessary additives such as sugar and gluten. Although it does not contain iron itself, the high but safe dose of lactoferrin effectively binds iron molecules, which significantly increases the absorption of iron from food or other supplements. As a result, the supplement helps prevent anaemia and protects against anaemia. Our testers noted that Nutridome lactoferrin strengthens the immune system, supports digestive processes and cares for a healthy intestinal microflora. In addition, lactoferrin has antibacterial and antifungal effects. The action of lactoferrin helps to maximise the body's absorption of iron, so that even from meals alone, more iron is absorbed. In the opinion of our testers, Nutridome lactoferrin deserves a high rating and opens today's ranking.
FeMe Complex from Health Labs Care is a capsule that contains iron and ingredients that support iron absorption, so it effectively replenishes iron deficiency. The supplement actively supports the functioning of the cardiovascular system. Our testers also noticed a reduction in fatigue and tiredness. The composition includes vitamins C and B12, nettle extract and other valuable components. The testers pointed out that the large size of the capsule makes it difficult to swallow. In addition, the need to take the supplement at a specific time in the morning was inconvenient for some. The manufacturer indicates that the product is not suitable for people with a tendency to form kidney stones or suspicion of such a condition. The price of the supplement is quite high, but its not inconsiderable effectiveness cannot be denied.
Lactoferrin from Aliness is a lactoferrin supplement enriched with an extra dose of vitamin C, enhances the immunomodulatory effect, outperforming other lactoferrin products. Testers appreciated the tablets for their simple formulation and effectiveness. Although primarily designed to support the immune system, lactoferrin not only helps the body to better absorb iron, which is key in iron deficiency, but also neutralises free radicals. The supplement supports the fight against bacterial infections, although the effects require longer, regular use. Derived from milk, lactoferrin is not suitable for vegans. The price of the product is relatively high and the pack contains only 30 capsules, but the effectiveness of the supplement has been evaluated positively.
Lactoferrin 100 by ASA is a capsule supplement available at most pharmacies at an affordable price. Testers were quick to point out that the pack contains only 15 capsules, which, at the recommended dosage of 2 capsules per day for adults, is only enough for one week. Several packs need to be consumed to see the effects of use. Testers also complained about the large size of the capsule, which makes it difficult to swallow. The lactoferrin in this supplement supports the absorption of iron, which is particularly important in the case of iron deficiency, but it does not contain the element itself. The product strengthens immunity and, thanks to fructooligosaccharides, supports the intestinal microflora. Unfortunately, it is not suitable for vegans.
Iron Complex by Now is an iron tablet that, according to our testers, does not show enough effectiveness in supplementing iron deficiency. Despite the manufacturer's promises, the iron in this supplement is not absorbed as well as one would expect. The product is more suitable for the prevention of anaemia, supporting oxygen transport in the blood, than for its treatment. Testers reported some increase in energy levels after regular use of Iron Complex, but these effects were not significant and only appeared after a longer period of supplementation. Unfortunately, those struggling with anaemia did not notice a significant improvement in performance. Additionally, some testers experienced allergic reactions while taking this supplement. Iron Complex by Now closes our list and is not recommended as the first choice by our female testers.
