The evidence behind the standard.
Everything claimed about Manapol® powder comes from somewhere. This page shows where: who ran the testing, what methods they used, what the results were, and which published literature the science rests on.
An independent university lab, not our own.
The analytical data on this page was generated by the Complex Carbohydrate Research Center at the University of Georgia.
The CCRC is an academic research center specializing in the structural analysis of complex carbohydrates — the exact class of molecule acemannan belongs to. Mannatech commissioned and paid for this analysis, as is standard for third-party ingredient testing. We send samples; the laboratory reports what it finds.
We believe in transparency. Testing instills consumer confidence and helps verify that Manapol® powder meets established specifications, ensuring product consistency.
Two methods, two different questions.
Aloe powder can be characterized in a lot of ways. These two answer the questions that actually determine whether a powder contains acemannan.
Molecular weight by Size Exclusion Chromatography (SEC)
Abbreviated SEC. The sample is passed through a column packed with porous beads. Small molecules wander into the pores and take longer to come out; large molecules can't fit and pass straight through. Sorting by exit time sorts the sample by molecular size.
This is what tells you how much of a powder sits in the 1–2 million Dalton range — the range that defines acemannan.
Glycosyl Analysis (Sugar Profile) by GC-MS
Glycosyl Analysis (Sugar Profile) is performed by gas chromatography-mass spectrometry (GC-MS). The polysaccharides are broken down into their individual sugar units, which are then identified and measured one by one.
Glycosyl analysis shows the saccharides that are present at detectable levels. In Manapol® powder, that is nine.
Acemannan is a defined substance.
"Acemannan" is not a general term for aloe extract. It is a name with a specification attached.
The Chemical Abstracts Service — a division of the American Chemical Society — and the United States Adopted Names Council define acemannan by molecular weight, at 1 to 2 million Daltons. A Dalton is a unit of molecular mass; one million Daltons describes a very large polymer, not a simple sugar.
That definition is the reference point for everything on this page. When we report how much of Manapol® powder falls in the 1–2 million Dalton range, we are reporting how much of it meets the published definition of the substance it claims to be.
We cite the published standard rather than paraphrasing it, so you can check it yourself.

Testing performed by the Complex Carbohydrate Research Center, University of Georgia. Molecular weight by size exclusion chromatography; monosaccharides by glycosyl analysis.
A polysaccharide's size changes where it goes.
Molecular weight is not a vanity metric. It determines how far a polysaccharide travels before the body breaks it down — and different distances mean different functions.*
The large fractionToo big to be absorbed high in the digestive tract. It travels the length of the intestine, where it can act as a prebiotic substrate supporting beneficial microbial activity.*
The smaller fractionAbsorbed higher up and able to enter circulation, where smaller saccharide structures participate in cellular recognition and communication.*
Manapol® powder is a broad-spectrum, polydispersed product derived from aloe vera, meaning it contains aloe saccharides across various molecular weights with a significant portion reaching 1–2 million Daltons. It is the cold processing and ethanol precipitation that preserve the polysaccharides — most importantly acemannan.
