What is the difference in the mechanism of absorption of organic and inorganic mineral?

Piyush Patel Thanks for your interest.

Here's a response from Rey Agra: There is no difference in the mechanisms of absorption between organic and inorganic minerals, the dissimilarity lies in the bioavailability of the mineral at the site of absorption. As the ligand (HMTBa for Mintrex) of organic trace minerals doesn’t dissociate as easily as inorganic trace minerals in low pH environments (like in the stomach), it protects the mineral from being complexed and thus making it much more available for absorption in the intestines. That is why you’d typically incorporate much less amounts of organic trace minerals in the feed, compared to inorganic sources, because a higher percentage of OTMs enters the animal rather than just being excreted like inorganic minerals.

I am afraid that answer is not valid for all organic trace minerals.

Dear Elizabeth Davies and Rey Agra ,

Your answer is correct : for most organic trace minerals (Mintrex, Proteinates, glycinates) there is no different mechanism of absorption, all these organic trace minerals are absorbed into intestinal epithelial cells via "mineral transporters", just like inorganic trace minerals. The only difference is the higher bio-availability, depending on the organic ligand.
However, there is one remarkable exception: the specific type of chelates of amino acids (Availamins) produced by Zinpro Corporation have been proven to have a different absorption mechanism: they are absorbed into intestinal epithelial cells as non-dissociated complexes via "amino acid transporters" . This unique mode of absorption of chelates of amino acids has been proven by different published research (Gao et al. 2014 and Sauer et al.2017) and can explain additional effects observed with this specific category of organic trace minerals on animal performance and immunity, on top of higher bio-availability.

Good overview of Mintrex chelated trace minerals. It has been shown that Mintrex trace minerals are significantly more bioavailable than inorganic trace minerals. Reduced mineral dietary intake and lower excretion to the environment … best of both worlds.

Inorganic minerals or Inorganic minerals with ligand – these are same but are being misquoted as Organic. Inorganic mineral bioavailability is very low 5 – 8% while bioavailability of minerals with Organic ligand is max. 40%.

“All bodily processes depend upon the action of minerals. Foods grown on millions of acres of land no longer contain enough minerals and are starving us”.

Ref. U S Senate Doc. No. 264 (74th Congress, 2nd session)

Companies offering 4 -5 Inorganic chelated minerals are not enough for industry.

We offer VANNAMIN a consortium of 77 organic minerals which are upto 100% bioavailable. They outperform all other minerals for performance.

Thank you for these explanations.
On the other hand, I understood that methioninate, glycinate and other mono-protein chelates were generally less bioavailable than chelates with one to three bonds with different amino acids. This should be in link with the question of the number of absorption sites at the digestive tract level ( absorption site for methioninates, glycinates, etc. are by definition less numerous than the whole of the absorption sites of the aa set) and also because multi-bridge to different amino acids (eg methionine, threonine) make the "bridges" stronger face to pH variation acid in particular.
Could I have clarification on this topic?
Thank you
