Easy Health Inc. DL-Methionine Powder has ≥99.0% test purity and is formulated to correct the first limiting amino acid shortage in corn-soybean animal diets. The pharmaceutical grade product shows good thermal stability up to 120°C during pelleting with a transmittance of > 98.0% and loss on drying of < 0.3%. We have over 11 years of experience in amino acid manufacture and are accredited by ISO, HACCP, Halal and Kosher, ensuring full traceability from sourcing to delivery. Each batch is rigorously tested by HPLC for heavy metals ≤10 ppm and microbiological count ≤1,000 CFU/g, ensuring constant feed-grade quality for poultry, swine, aquaculture and ruminant applications globally.

The product is a racemic supplement of an essential amino acid with equal parts of D and L optical isomers. It is the industry’s answer to the biggest problem in vegetable-based feed formulations: lack of methionine.
If your feed recipe is corn and soybean meal, methionine is the first limiting factor. This means that even if lysine or threonine are abundant, they cannot promote development until methionine needs are addressed. You maximise the nutritious value of your existing protein sources by adding our product.
The D-isomer is readily utilised by animals to produce bioactive L-methionine with 100% utilisation. This makes it a cost-smart alternative to pricey animal proteins like as fishmeal, while encouraging faster growth, improved immunity and decreased environmental nitrogen waste.

First Limiting Amino Acid Problems Resolved
Your animals cannot create muscle, feathers or eggs faster than the available supply of methionine. Our powder fills that gap right away, increasing protein production all throughout your tissues.
Cuts Feed Costs Without Sacrificing Performance
Replace 2–3% of expensive fish or soybean meal with accurate methionine supplementation. You will get the same or higher weight gain, egg production and milk yield for less feed cost.
Better Feed Conversion Ratio (FCR)
Animals transform each kilogram of feed into extra meat, milk or eggs. Less waste means more profit and less environmental footprint. Especially crucial for heavy activities.
Heat-Stable During Processing
Our crystalline DL-Methionine Powder is stable under high temperature pelleting and extrusion up to 120°C. No loss of activity, no clumping and great flowability in automated dosing systems.
Supports Health & Immunity
Methionine is a precursor of glutathione and increases antioxidant defences. It also helps the liver in detoxifying, reduces stress-related mortality and enhances the durability of the herd or flock during transit or vaccination.
Certified Quality You Can Rely On
Each batch is approved under ISO, HACCP, HALAL and Kosher criteria. Certificates of Analysis (CoA) with complete traceability from raw material to final packaging.

Poultry (Broilers & Layers)
Encourages rapid weight gain, improved feathering and increased egg production. Suitable for high density farms switching from fish meal to plant proteins.
Swine (Growers & Sows)
Increase lean muscle growth, enhance reproduction, and reduce nitrogen excretion in manure – complying with tighter environmental restrictions.
Aquaculture ( Fish & Shrimp)
Substitute the methionine-deficient soy- or pea-based diets. Support survival rates, metabolic health and uniform growth in recirculating aquaculture systems (RAS)
Dairy & Ruminants (Beef)
Step up dairy cows' milk production and protein content. Encourage speedier completion especially where grazing or silage quality is variable.
Pet Food (Premium Formulations)
Maintain the best balance of protein for skin, coat and urinary health. It is used as a nutritional acidifier in extruded kibble for cats and dogs.

We use a five-point inspection methodology on every production batch:
1. Assay Purity (HPLC/Titration) Confirmed ≥99.0% active content to ensure the labelled potency.
2. Loss on Drying: Controlled to < 0.3% to avoid caking and microbiological contamination due to moisture during storage.
3. Heavy Metals Testing: Lead ≤10 ppm, Arsenic ≤2 ppm – fully compliance with FAMI-QS and international feed safety standards.
4. Particle Size Distribution: Sieve analysis helps in homogeneous blending of premixes, avoiding segregation in bulk handling.
5. Microbial Limits Total aerobic count – ≤1,000 CFU/g E. coli and Salmonella – Negative tests Protects animal health and end-product safety
