A capsule of organ powder is the last link in a long chain. Most of the decisions that shape it are made before a formulator ever sees the powder: what raw material went in, how pathogens were controlled, how it was dried and milled, and what paperwork came with it.
This post follows that chain for the material Gembra Health distributes, one stage at a time. It is written for buyers qualifying a supplier, so at each step it says who does the work.
Who makes the powder, and who sells it?
Two companies, one building. Gembra Health is the distributor. Our sister company, Flatiron Food Factory, is the USDA-inspected manufacturer that heat treats, freeze-dries and mills our flagship material in Loveland, Colorado.
That split matters when you qualify a supplier. A broker can forward you a certificate, but it cannot tell you what happened to the material before it arrived. We can, because the people who processed it work in the same building. Our manufacturing page explains how the two companies fit together.
Stage 1: raw material
The first decision shapes everything downstream. Our flagship tier is US grass-fed, human-grade raw material under USDA inspection, rather than the FDA pet-downgraded material much of this category starts from.
It is not the only option. Material comes in four tiers: grass-fed, grass-finished, organic and conventional. We also distribute material from New Zealand, Australia, South America and China, all of it stocked in the United States. Tier and origin are separate facts, and we state both for every lot.
The New Zealand, Australian and South American material is HPP-processed to those regions’ standards. It is a legitimate, less expensive option and sometimes the right call. Our quality and sourcing page sets out the tiers and origins in full.
Stage 2: heat treatment
How are pathogens controlled? For our flagship material, Flatiron heat treats the raw material in commercial ovens at a minimum of 145°F for seven minutes, and higher where a program calls for it.
That replaces the kill step most of the industry uses: high-pressure pasteurization, usually paired with a chemical bath or irradiation. Our flagship material goes through none of the three. It comes out of the ovens looking almost rare, and then it goes on to freeze-drying.
Stage 3: freeze-drying
Why freeze-dry rather than spray-dry or heat-dry? Freeze-drying removes water from frozen material by sublimation, so the powder never goes through the heat of spray-drying or conventional dehydration.
The process runs in three parts. The material is frozen. Under vacuum, the ice turns directly to vapor, which is primary drying. A final stage, secondary drying, removes the remaining bound moisture. Flatiron runs this step for our flagship material.
Freeze-dried is our premium tier. Desiccated powder is the value tier, sourced rather than made in house, and we tell you which one you are buying. Our post on how freeze-drying works for glandular powders goes further into the drying step.
Stage 4: milling to spec
Milling is where a powder becomes something a production line can run. Flatiron mills in house, with a hammer mill for most material and a cryogenic mill for very fine mesh, high-density specs and high-fat material such as heart. A milling scientist on staff decides which one a lot needs.
Density and mesh are set to your formulation, then held batch to batch. That is what keeps capsule fill weights steady from one lot to the next. Most freeze dryers have no milling capability and send dried material out to a separate mill, and that handoff is where lot-to-lot drift tends to start.
Material is non-defatted by default, and defatted on request. Our post on defatted vs non-defatted organ powders covers when each one makes sense.
Stage 5: testing and documentation
What ships with the powder? A certificate of analysis, the lab results behind it and a specification sheet, with every order. The certificate covers microbial testing, heavy metals and water activity.
Anything else your file needs, such as allergen statements or country-of-origin records, is available on request. Nutritional analysis is something we assist with rather than supply, because the numbers depend on your finished formulation rather than on the raw lot.
Stage 6: warehousing and dispatch
Finished material is warehoused in Loveland, Colorado. Material in stock ships in 7 to 10 business days; a custom run takes 6 to 8 weeks.
Imported origins sit on a domestic shelf too. Buying New Zealand or Australian material from us means ordering from US stock, not waiting on a sea crossing and a customs clearance. Every powder is single-ingredient, with no fillers, flow agents or additives.
Where does the powder get encapsulated?
With your encapsulator or co-packer, or with one Flatiron introduces. Gembra supplies the bulk powder. Packaging runs from bulk to retail-ready with lot coding and labeling, done in house for some customers, and encapsulation, pouching and larger work go to trusted partners that Flatiron introduces or manages.
That lets you treat us as a one-stop shop. Tell us what the finished product needs to be, and we work out the material and manage the relationships from there. If all you need is the powder, that works too.
Claims on the finished product belong to the brand owner, who makes and substantiates them. What we supply is the material, and the paperwork that shows what it is.
Why the whole chain matters to a buyer
Each stage leaves a mark on the powder you receive. Raw material decides the grade. The kill step decides how processed the material is. Milling decides whether it runs on your line the same way twice. Documentation decides whether your quality team can sign it off without a chase.
When you qualify an organ powder supplier, ask about every link, not just the last one. Request a quote with the organ, volume and mesh or density spec you need. Orders start at 10 kg per ingredient, and quotes come back within 12 to 24 hours.
