Which is right spelling fiber or fiber in psyllium husk?

Answer 1

The English (UK) spelling of fibre has French origins, whilst the alternative US spelling of fiber has Germanic origins and is still used in many European countries where the origin of their native language is more Germanic than Latin. Within the UK fiber optics industry both spellings are now very common, although the correct English spelling should be 'fibre', and hence as a UK based company this is the spelling adopted throughout this website. For training courses in the USA or various European countries (such as Germany, Holland, Denmark, Sweden, Norway and so on). From http://www.lucidos.co.uk/

Answer 2

Both "fibre" and "fiber" are correct spellings of the word depending on the region. In British English, "fibre" is more commonly used, while in American English, "fiber" is the preferred spelling. In the context of psyllium husk, either spelling can be used.
