The natural product "Floradix formula" is generally considered safe to take while breastfeeding, as its key ingredients such as iron and vitamins are found in regular food and are safe for consumption. However, it is important to be cautious of the non-medicinal ingredients in the product, such as extracts of couch grass and kelp, which may have uncertain impacts during breastfeeding. It is also worth noting that Floradix provides a relatively small amount of iron compared to other iron supplements, so it may be necessary to consider other options if higher iron levels are needed to replenish reserves. Additionally, liquid forms of iron supplements can potentially stain teeth and tongue.
