Chemical analysis of nutrient, ionic drinks - (Jun/30/2008 )
Hi all,
I would have a little bit, here at Bioforum, unusual question. There are many nutrient (supplement) drinks or ionic drinks used for endurace sports. I am little bit in doubt, whether the company information about the amount of minerals, vitamins, amino acids etc. which is written on the box or in the "data sheet" to given product is correct (is true).
My question is:
Do you know about any reliable scientific study (research paper), where would be performed chemical analysis of some of the most known (used) nutrient (supplement) drinks or ionic drinks? To show what is the real amount/concentration of components such as minerals, vitamins, amino acids, carbohydrates etc. in the given product.
Thanks.

I guess the better (more reliable, believable etc) companies have independent laboratories (there are specialised companies for this) that control their drinks and confirm that the claimed characteristics (escp. microbiologically safe, content of solved ions/minerals, etc) are fulfilled and or follow legal or other regulations. Some have it on the bottle (here many mineral water companies), on their website or I guess they send you the reports on enquiry.

Gas chromatography and mass spec would be the way to go.
some health magazines carry out independent research on the content of health supplements.
try looking up a few (they mainly cater to bodybuilders).
sports drinks are usually water with a bit of salt, and a bit of sugar... occassionally caffine, and/or protein.
the "best" sports drink, post workout, is chocolate milk.

1st - why do you have doubts re. the truthfulness of labeling? Whereas it may not be complete or as detailed as you'd like, false ingredient labeling is a violation of federal law and it's unlikely that folks will risk their corp reputation and risk recall or seizure action to monkey with information that few read and even fewer understand.
Go to pubmed or google scholar and review the literature. If you'd like more detail, ask the company. If you think they're falsifying data - go test it yourself.
