Choline is often sold as a supplement without any CAS provided
“DL-Choline Bitartrate should not be used in pharma or food applications although the price is normally more attractive. Studies have that shown the DL-form has nefrotoxic effects (1). In Europe, according to the CODEX and European Union, only L-Choline Bitartrate is allowed because it is mentioned in DAB and in the USP monograph. The DL form does not comply with these monographs. Moreover, according to the FDA, L-Choline Bitartrate is considered GRAS affirmed (21CFR182.8250_2010) but not the DL-form.” – http://www.geelawsonnutritional.com/news/gee-lawson-news/42-what-you-are-buying-might-not-be-the-right-source-of-choline.html
“Urolithiasis in rats consuming a dl bitartrate form of choline in a purified diet.” – https://www.ncbi.nlm.nih.gov/pubmed/16158911 — Urolithiasis = Kidney stone disease
- @David Hedlund: This is not a credible or verifiable source. It actually appears to be a marketing ploy to promote that vendor's supply over others. The neurotoxicity claim is totally unsupported by the citation they provide. Pseudoscience is not allowed here. Clarity (talk) 23:57, 24 March 2018 (UTC)
- @Clarity: What about "“Urolithiasis in rats consuming a dl bitartrate form of choline in a purified diet.” – https://www.ncbi.nlm.nih.gov/pubmed/16158911 — Urolithiasis = Kidney stone disease"?
- @Clarity: The reason why I'm worried is because I've supplemented with a product just labeled "Choline bitartrate". Don't you othink kidney stone disease is supported by https://www.ncbi.nlm.nih.gov/pubmed/16158911 ? --David Hedlund (talk) 00:17, 25 March 2018 (UTC)
- @David Hedlund: This is what consumer watch agencies are for. We are not a consumer watch agency. Unless something any one vendor does is noteworthy enough to make the news at a major news outlet, it does not meet the requirements for notability on this site. As for the kidney stone point, well, a single study in mice is not a strong enough piece of evidence to make a claim about its effects in humans. If you can find a human clinical study reporting kidney stones as a potential effect, then it can be added in. Clarity (talk) 00:24, 25 March 2018 (UTC)
