Heme iron therapy has none of these problems. Dosage is once per day and there are no interactions with food or drink or other medications.
Since we humans are omnivores our bodies are programmed to use natural hemoglobin from animal sources as the main pool if iron in the diet. It is taken up much more efficiently using a different mechanism than plant-sourced or synthetic forms of iron, so-called non-heme iron.
Heme iron in food supplements have been used in large scale in Scandinavia since the 1970-ies.
However, no serious side-effects or poisonings have ever been reported in a massive user base since, and in clinical trials both efficacy and tolerance are outstanding in comparison.
Today the OptiFer® series can be considered containing only natural heme iron as the active ingredient (years ago most “heme iron”-tablets contained over 90 % of the iron as non-heme).
The OptiFer series is well-documented,
safe, natural and very efficient.
