Quick answer: Calcium hydroxy methionine (MHA-Ca) and DL-methionine are different methionine sources. A useful comparison must consider the current assay or declared nutritional basis, formulation method, calcium contribution, product form and destination-market rules rather than comparing price per tonne alone.

Different product identities

MHA-Ca is the calcium salt of a methionine hydroxy analogue. DL-methionine has a different chemical identity. These products should be reviewed using their current specifications and the nutritional basis used by the buyer’s formulation system.

Do not assume a one-for-one replacement. A qualified nutritionist should calculate any change using validated data for the exact products.

Assay, nutritional basis and calcium

Ask how assay or methionine activity is expressed on the current TDS and COA. The calculation basis should be clear before comparing inclusion cost.

MHA-Ca also contributes calcium. The formulator should consider this within the complete mineral and amino-acid programme instead of evaluating the ingredient in isolation.

Species and formulation review

MHA-Ca may be considered in poultry, swine, ruminant and aquaculture formulations where the product and local rules are suitable. Species, life stage, diet composition and processing conditions can affect the decision.

ADDEASY does not recommend a universal dose. Inclusion should be determined by a qualified formulator using the current product specification and destination-market requirements.

Procurement and supplier documents

Request the current specification, representative COA, SDS/MSDS and available technical documents. Confirm physical form, relevant impurity limits, packaging, shelf life, quantity, destination, Incoterm and delivery window.

Because unverified CAS, formula, assay and packaging data can mislead buyers, these parameters should be taken from the current approved product documents rather than inferred from another supplier’s page.

Buyer Checklist

• Intended application and destination market
• Required grade, standard and target specification
• Quantity, packaging and delivery schedule
• Destination port and Incoterm
• COA, SDS/MSDS, TDS and trade-document requirements
• Sample and testing requirements, when applicable

Frequently Asked Questions

Is MHA-Ca the same as DL-methionine?

No. They are different methionine sources with different product identity and formulation basis.

Can MHA-Ca replace DL-methionine one for one?

Not automatically. A qualified nutritionist should calculate any substitution using current validated product data.

Does MHA-Ca contribute calcium?

Yes, the calcium contribution should be included in the complete formulation review.

Which animals can use MHA-Ca?

It may be considered for poultry, swine, ruminant and aquaculture formulations where suitable and permitted.

What information should an RFQ include?

Include target species, application, required specification, quantity, destination, packaging, documents and delivery terms.
