Trace mineral feed additives
01Overview and value chain
Markers: [EC: EU Feed Additives Regulation (EC) 1831/2003 — trace element authorization | OECD: Agricultural biotechnology | Regulator: FDA (USA)]
Trace mineral feed additives replace inorganic sulfate or oxide forms of zinc, copper, manganese, cobalt and selenium with organic (amino-acid-chelated) or hydroxy forms that livestock absorb more completely and excrete less of into manure. Novus International’s MINTREX line uses a verified 2:1 bis-chelate structure — two molecules of a methionine hydroxy analog bound per metal ion — while Zinpro’s ProPath and 4-Plex lines combine amino-acid complexes of zinc, manganese, copper and cobalt, several OMRI-listed for certified organic livestock and poultry production. The commercial case rests on more than 500 published feeding trials behind the bis-chelate category alone, and on a regional feed-minerals market (India) valued at $487.6 million in 2026 and projected to reach $1.03 billion by 2035 at an 8.70% CAGR as dairy operations expand mineral supplementation under tightening feed-safety standards.
Key directions of trace mineral feed additives:
- Amino-acid chelated minerals (Amino-Acid Chelated Minerals): a metal ion bound to one or more amino acid ligands (e.g., methionine, glycine), raising intestinal absorption versus free inorganic salts.
- Hydroxy trace minerals (Hydroxy Trace Minerals): metal-hydroxide complexes (e.g., copper/zinc/manganese hydroxychloride) with lower solubility in the upper gut, reducing antagonism with other nutrients.
- Bis-chelated complexes (Bis-Chelated Complexes): a verified 2:1 ligand-to-metal structure (e.g., two HMTBa molecules per metal) designed to keep the full complex intact through digestion rather than dissociating.
- Sole-source supplementation (Sole-Source Supplementation): replacing a mixed inorganic/organic mineral program with a single, fully organic source calibrated to species-specific requirements.

Cross-cutting technologies of the sector:
- Bis-chelate verification assays (Bis-Chelate Verification Assays): analytical confirmation that a 2:1 ligand-to-metal structure stays intact rather than dissociating in solution.
- OMRI/organic-certification compliance (OMRI Organic Certification): listing trace mineral products for use in certified-organic meat, milk and egg production.
- Gene-expression bioavailability panels (Gene-Expression Bioavailability Panels): molecular assays (e.g., in broilers) that quantify how a mineral source affects nutrient-responsive gene expression.
02US
The US hosts the two largest organic/chelated trace mineral originators and the deepest published trial base behind the category.
bis-chelate verification, OMRI organic listings, poultry-science trial base
- Novus International MINTREX: bis-chelated copper, zinc and manganese with a verified 2:1 HMTBa-to-metal structure, backed by more than 500 feeding trials.
- Zinpro ProPath / 4-Plex: amino-acid complexes of zinc, manganese, copper and cobalt, with several SKUs OMRI-listed for certified-organic production.
- Poultry Science Association annual meeting (July 9–13, 2026, Toronto): the venue where US originators present broiler copper-nutrition and reduced-energy-feed trial results each year.
03CN
China’s trace mineral market is supplied mainly through imported organic and hydroxy mineral brands plus a large domestic premix-compounding industry; public information on a dedicated Chinese organic-trace-mineral originator at the scale of the US/EU leaders was not confirmed in this pass, so this section stays at the policy level.
premix-industry scale, feed additive registration, hydroxy-mineral imports
- MARA feed additive registration list: new trace mineral complexes (organic or hydroxy forms) must clear China’s national feed additive catalogue before commercial sale.
- Domestic premix compounders: large-scale Chinese premix and compound-feed groups blend both inorganic and licensed organic/hydroxy trace minerals into finished rations rather than originating the chelated-mineral chemistry themselves.
- Import channel for chelates/hydroxy forms: US and EU-originated bis-chelate and hydroxy trace mineral brands reach Chinese livestock operations mainly through import and local distribution rather than domestic manufacture.
04EU
The EU is the home base of two of the sector’s largest organic/hydroxy mineral suppliers and enforces authorization of every trace element additive under a dedicated feed regulation.
EU 1831/2003 trace-element authorization, hydroxy-mineral chemistry, organic proteinates
- Alltech Bioplex / Sel-Plex: proteinate-form organic trace minerals (zinc, manganese, copper, cobalt) and organic selenium, sold globally from an Irish/EU base.
- Trouw Nutrition Selko Optimin / IntelliBond: chelated (Optimin) and hydroxy (IntelliBond) trace mineral lines distributed internationally, including a 2026 exclusive-distribution expansion in Southeast Asia.
- EU Regulation (EC) 1831/2003: requires every trace element feed additive — organic, hydroxy or inorganic — to hold an EU authorization before sale, renewed on a fixed cycle.

06Tech stack and innovations
The stack turns a commodity mineral salt into a bioavailable, gut-stable complex.
- Bis-chelation chemistry (Bis-Chelation Chemistry):
- two ligand molecules (e.g., HMTBa, a methionine hydroxy analog) bind one metal ion in a verified, non-dissociating 2:1 structure.
- case: Novus reports the bis-chelate stays intact where simpler 1:1 chelates can dissociate before intestinal absorption.
- Hydroxy trace mineral chemistry (Hydroxy Trace Mineral Chemistry):
- metal-hydroxide complexes have lower solubility in the rumen/upper gut, limiting unwanted mineral-mineral and mineral-phytase interactions.
- case: hydroxy selenomethionine forms are marketed specifically for heat-stress resilience support.
- Gene-expression bioavailability testing (Gene-Expression Bioavailability Testing):
- broiler trials measure nutrient-responsive gene expression to compare mineral sources beyond simple growth/feed-conversion metrics.
- case: recent broiler copper-nutrition studies were presented alongside reduced-energy-feed research at the 2026 Poultry Science Association meeting.

└───────────────────────────┘ └───────────────────────────┘Stage 1: Metal salt sourcing
Zinc, copper, manganese, cobalt and selenium salts are procured as the base feedstock for downstream chelation.
Stage 2: Ligand synthesis
Amino acids (methionine, glycine) or hydroxy analogs (HMTBa) are prepared as the binding ligand.
Stage 3: Chelation/complexing
Metal and ligand are combined in a verified ratio — a 2:1 bis-chelate for MINTREX-type products, a proteinate bond for Bioplex-type products.
Stage 4: Bio-efficacy trial
Feeding and gene-expression trials confirm the complex survives digestion and improves the target outcome (immunity, fertility, hoof/eggshell quality); the bis-chelate category alone carries over 500 published trials.
Stage 5: Premix blending
The validated mineral complex is blended with vitamins and enzymes into a finished premix.
Stage 6: On-farm feeding audit
The premix enters the final ration; regional demand growth (e.g., India’s feed-minerals market, $487.6M in 2026 to a projected $1.03bn by 2035) is tracked against tightening national feed-safety standards.

AI note: trace-mineral-feed-additives (EN)
Key directions:
- Amino-acid chelated minerals — a metal ion bound to methionine/glycine ligands, raising intestinal absorption over free inorganic salts.
- Hydroxy trace minerals — metal-hydroxide complexes (Cu/Zn/Mn hydroxychloride) with lower upper-gut solubility, reducing mineral-mineral/phytase antagonism.
- Bis-chelated complexes — a verified 2:1 ligand-to-metal structure (e.g., two HMTBa molecules per metal) designed to stay intact through digestion.
- Sole-source supplementation — replacing a mixed inorganic/organic program with one fully organic source calibrated per species.
Regulatory:
- EU: Regulation (EC) 1831/2003 requires every trace element feed additive — organic, hydroxy or inorganic — to hold an authorization, renewed on a fixed cycle.
- US: no dedicated trace-mineral-specific statute; FDA regulates feed ingredients generally, and organic-certified products additionally need OMRI listing.
- China: MARA’s national feed additive catalogue gates new organic/hydroxy trace mineral complexes before commercial sale; a domestic originator at US/EU scale was not confirmed in this pass.
Companies not in table: Phytobiotics (confirmed via Sangrovit, a phytogenic alkaloid blend — a gut-health additive, not a trace mineral product, so excluded as off-topic for this specific industry); Denkavit/Adisseo Selisseo (hydroxy-selenomethionine brand surfaced in the same search cluster as Trouw’s products but is a distinct company’s product, not attributed here to avoid misattribution).
Processing note: the bis-chelate category’s differentiator is verification — Novus reports over 500 feeding trials specifically validating that its 2:1 ligand-to-metal ratio survives digestion intact, versus simpler 1:1 chelates that can dissociate before intestinal absorption; this verification burden is what separates the leading originators from generic “chelated mineral” claims in the wider premix market.
Relevance: trace mineral chemistry sits upstream of both animal-welfare and environmental-excretion outcomes — better bioavailability at a lower inclusion rate is the shared claim across all five companies here, and it’s also why the EU treats every trace element additive as requiring its own authorization rather than a blanket category approval. India’s feed-minerals market ($487.6M in 2026 to a projected $1.03bn by 2035) is the clearest quantified regional growth signal found in this pass.
