Why This Number Matters

Buyers Don't Purchase
Colostrum.
They Purchase IgG.

The entire commercial value of bovine colostrum sits in one number. Immunoglobulin G concentration. It determines efficacy, claim support, and the price your formulation can command in market.

Most Indian suppliers cannot clearly state this number. We print it on every COA, verify it with every batch, and back it with third-party ELISA testing.

That transparency alone separates us from 90% of domestic competition.

  • Third-party ELISA-verified IgG on every batch
  • Printed COA on letterhead with accredited lab name
  • IgG% disclosed before purchase commitment
  • Batch-to-batch consistency guarantee
Our Target Market — India

The Right Buyers.
Mapped and Verified.

We supply ingredient-grade colostrum to the companies that actually manufacture. Not the brands that outsource everything.

Baddi and Haridwar cluster. The manufacturing backbone of India's nutraceutical industry. These CMOs formulate for 20 to 50 brands each. One CMO relationship means access to dozens of formulations simultaneously.

The Collection Protocol

Quality Starts at
Hour Zero.

Colostrum has a collection window of 24 to 72 hours post-calving. What happens in that window determines everything that follows.

Newborn calf feeding at dairy farm
01
The Collection Window
Collected within 6 hours of calving. The window when IgG concentration peaks. Not 12 hours. Not 24 hours. Six.
Stainless steel dairy cold storage tank
02
Cold Chain Preservation
Immediately chilled to below 4°C at the collection point. Deep freeze infrastructure at every collection center. Temperature log maintained throughout transit.
Scientist performing ELISA pipette test
03
In-House Laboratory Testing
Every batch tested in-house for IgG, microbial count, moisture, and heavy metals before processing. Substandard batches rejected, not blended.
Industrial spray drying food processing facility
04
Precision Processing
Spray drying or freeze drying depending on the product variant. Parameters optimized to preserve IgG bioactivity, not just yield.
Laboratory certificate of analysis being stamped
05
Third-Party Verification
Final batch verified by an accredited third-party lab. ELISA-tested IgG concentration confirmed. COA generated and dispatched with every shipment.

"This is the protocol that most Indian suppliers cannot document. We can."

Most nutraceutical brands in India are paying for colostrum. Very few are actually getting it. Colostrum is only colostrum if it's collected within 6 hours of calving. After that, IgG concentration drops sharply with every passing hour. Most suppliers don't disclose collection time. Most COAs don't specify IgG%. Most buyers never ask. We test every batch. We print the number. We let the COA do the talking. #Nutraceuticals #FormulationScience #BovineColostrum

India imports significant quantities of colostrum ingredients from New Zealand and the US. The reason isn't quality. India has some of the world's largest cattle populations. The reason is that nobody here has built the collection protocol, processing infrastructure, and quality documentation that B2B ingredient buyers require. That gap is closing. #MakeInIndia #NutraceuticalIndia #BovineColostrum
