What is Choline?
Choline is an essential nutrient rather than a peptide — a small quaternary ammonium compound that sits upstream of two entirely different systems: it is the precursor to the neurotransmitter acetylcholine, and to phosphatidylcholine, the phospholipid that forms the bulk of cell membranes. Very few molecules serve as substrate for both signalling and structure.
It is supplied as a high-concentration solution at 500 mg/ml, so no reconstitution step is required. The concentration calculator is still useful for working out dilutions to a target working concentration.
Research context
In research contexts choline is studied for its role in cholinergic signalling, methyl-group metabolism through its oxidation to betaine, and lipid transport. It is most often included as a supporting or ancillary compound in nootropic and metabolic study models rather than as the primary variable.
That supporting role puts it alongside the neuroactive references Semax, Selank and cerebroprotein hydrolysate in our cognitive and neuro research collection, and near NAD+ where methyl-group and cofactor metabolism overlap.
Quality and handling
Supplied by Helixa Biotech as a standardised liquid reference preparation for laboratory workflows. Our approach to sourcing and batch documentation is set out on the Research and Quality page — if your study design requires specific batch documentation for this preparation, contact us before ordering.
Storage
As a supplied solution it needs no reconstitution, but a liquid has a shorter working life than a sealed powder: keep it cool, capped and out of direct light. General principles are covered in the storage guide and on our storage information page.

Frequently asked
No. Choline is supplied strictly as a reference material for in-vitro laboratory research. It is not for human or animal consumption and is not intended for diagnostic or therapeutic use.
Yes. Every batch is independently tested by Testides and Peptide Test Canada for HPLC purity and mass-spectrometry identity, and ships with a batch-specific certificate of analysis (COA).
Choline is available in 20 ml (500 mg/ml). Per-vial pricing is shown on this page.
Choline is supplied as solution. Use the reconstitution calculator to work out concentration and dosing volumes for your research, and see the storage and handling guide for temperature and shelf-life guidance. Store the lyophilized vial at -20 degrees C, desiccated and protected from light.
