What does aneurin mean?
Aneurin is an alternative name for thiamine, better known as vitamin B1, an essential water-soluble nutrient that the body requires to convert carbohydrates into usable energy and to keep the nervous system working properly. Because humans cannot store much of it, a steady dietary supply—from whole grains, pork, legumes, and seeds—is necessary; prolonged deficiency leads to beriberi, a disease marked by nerve inflammation, weakness, and heart complications. The name itself nods to this neurological connection, deriving from the Greek root for nerve. Although 'aneurin' remains familiar in British pharmacology and older medical literature, where it often appears in the form 'aneurin hydrochloride', modern labels and clinicians overwhelmingly prefer 'thiamine'. For general readers, encountering 'aneurin' usually signals a slightly dated or British scientific register rather than a different substance altogether—it is simply vitamin B1 under one of its historical names.
nounAneurin is another name for thiamine, or vitamin B1, an essential water-soluble vitamin that the body uses to convert carbohydrates into energy and to maintain proper nerve function.
- Another name for thiamine (vitamin B1), the water-soluble vitamin essential for carbohydrate metabolism and healthy nerve function.
"A diet lacking whole grains can lead to a deficiency of aneurin, causing fatigue and nerve problems."
"Polished-white-rice diets provided little aneurin, which is why beriberi once ravaged communities that relied on them."
"The supplement label listed aneurin hydrochloride as the source of vitamin B1."
Rarely pluralized; the vitamin is typically discussed as a single substance or measured in milligrams.
"Different salt forms of aneurins were tested for stability."
The 'aneur' in aneurin points to its nerves: scientists named this B vitamin after the nerve inflammation that appears when the body runs short of it.

Etymology of aneurin
The word aneurin was coined in the early twentieth century when researchers were identifying the 'anti-beriberi' factor in foods. Its name derives ultimately from the Greek 'neuron', meaning nerve, combined with a prefixal element—a reference to the nerve inflammation (polyneuritis) characteristic of thiamine deficiency. It shares this Greek root with modern medical terms such as neural, neuritis, and neurology. In contemporary usage it has largely been superseded by the synonym thiamine.
How aneurin is actually used
Aneurin is chiefly a British pharmaceutical and technical term; in everyday usage and American English, 'thiamine' or 'vitamin B1' is far more common. The name reflects the vitamin's role in preventing nerve disorders such as beriberi and polyneuritis.
Easily confused with aneurin
An aneurysm is a dangerous bulge in a blood-vessel wall, whereas aneurin is simply another name for vitamin B1; they are unrelated despite the shared opening letters.
