Dear Sirs,

I had a look at the websites and will pass the details of these to the Doc.

However, I could not find the specific information he is initially looking for, i.e. the actual constituents of wine, especially L-arginine. Can you let me know how/where I can find this 'list' or whom I can ask?

Good morning Lee,

The first response to your question has come in from Dr. Phil Norrie in Australia.

L- arginine is found in wine at levels of between ..02 and.1g/l. His source was making good wine by Bryce Rankin 1993 edition, page 297.

Re health implications, apart from being an essential amino acid - little info received yet.

Hope this helps.

Helena
