Why can't you find iron in Everyday Bases from nikalab?

Almost 30% of women in the world have anemia, and its most common cause is iron deficiency ¹ . In Poland, approximately 25% of women aged 15 to 49 suffer from anemia ² . Does this mean that each of us must supplement iron preventively? Absolutely not.

Both iron deficiency and excess carry serious health risks. In other words, what will save one Polish woman may harm three if supplementation is implemented without medical supervision.

Iron can be toxic.

Under normal conditions, very few free iron molecules circulate in our blood. It is either part of the hemoglobin protein, stored for storage in the form of ferritin protein, or bound to the transport protein transferrin. If we start supplementing iron unnecessarily, there are more free iron molecules in the bloodstream. When there are a lot of them, they start to damage our cells. Excess iron leads to poisoning and this is quite common, especially among children ³ . In the early stages, poisoning manifests itself in the form of abdominal pain, nausea and vomiting.

If we continue unnecessary iron supplementation for a long time, it may accumulate in internal organs , causing, among others: cancer ⁴ , brain and liver damage, sometimes even fatal ⁵ .

Iron during pregnancy – is it worth supplementing?

Iron is one of the key elements during pregnancy , its deficiency may cause premature birth and prevent the fetus from gaining weight. It may also slow down the development of a future child's brain ⁶ .

But excess iron during pregnancy also has its side effects. Most scientific societies in the world, including the Polish Gynecological Society (PTG), recommend taking this element only if its deficiency has been confirmed by tests. ⁷ . Doctors and scientists draw attention to the fact that an oversupply of iron may lead to the development of insulin resistance, diabetes of both types ⁸ , also gestational diabetes ⁹ and preeclampsia (preeclampsia). ¹⁰ . These complications occur if a woman planning a pregnancy or a pregnant woman takes iron supplements for a long time "just in case" without having anemia. This is a classic case where we want to do well and achieve the opposite effect than intended.

Taking into account the PTG recommendations and scientific evidence on the potential harmfulness of iron supplementation during pregnancy, we have not added this element to the Everyday Database for pregnant women .

Unpleasant symptoms after iron supplementation.

We have already explained that you do not have to take iron prophylactically, unnecessarily. But apart from the health risks associated with such supplementation, in most cases it is simply not very pleasant. Probably everyone who takes iron has experienced one of these unpleasant symptoms at least once :

• constipation,
• stomachache,
• diarrhea,
• black stool,
• nausea,
• vomiting,
• black deposits on teeth (if the iron is in liquid form).

It is generally considered that these should not be a cause for concern and are normal, although sometimes they can be an early sign of iron poisoning or digestive diseases. Regardless of the causes, these symptoms are troublesome and everyone would prefer to avoid them, but people with diagnosed iron deficiency will unfortunately have to face them.

Why is there no iron in Everyday Bases from nikalab?

To sum up , based on the hard arguments mentioned above, we have not added an element to our databases on a daily basis, supplementation of which is not necessary in most cases. Moreover, taking iron for a long time without specialist supervision may do more harm than good . However, if you really have iron deficiency, your doctor must select the therapeutic dose.
