Vitamin C

Filed under: Science — Cat @ 12:49 pm

I am always interested in news on Vitamin C (ascorbic acid) in all its guises as it was the subject of my PhD.

Over at Respectful Insolence, Orac has a post debunking the Linus Pauling recent vindication. A debunking of the debunking of the debunking – does that make it a (debunking)3 ? Not that LP wasn't a genius, he just didn't understand nutrition or clinical trials. Read the article and see for yourself:

BTW if you do consume large doses of vitamin C not all of it will be absorbed and once the blood plasma level is greater than 14 mg/l it is excreted in the urine*.

*This information is from my nutritional text book (Davidson, Passmore, Brock and Truswell 1979) which also has a very thorough section discussing & debunking Pauling's ideas. It would interesting to see if later editions have the same discussion.
