I have received a response to my email to Tesco regarding the claims made on their behalf in a Daily Mail article about Bio-Synergy Skinny Mousse.
Dear Mr Hawcock,
Thank you for your patience.
I have spoken with our buyer and supplier and sourced the information you have requested. Please find attached an information pack from the supplier about Chromium.
Further information on the studies carried out can be found on the EFSA website:
Once again, thank you for your patience and if you require anything further please do let me know.
The request for links to the research produced this pdf of an information pack about the supplements. Lots of nice graphs but of course we can’t see the working. I did note that the study samples were quite small – as low as six in one case. Furthermore, the larger studies were of atypical groups such as diabetics and athletes. Not at all obvious that the results are applicable to the general population.
I have sent this email in response:
Dear Ms Wimbleton
Thank you for your reply.
While the results described seem impressive at first sight, I note that many of the studies have quite small numbers of participants and in some cases they are rather atypical – diabetics and athletes for example.
I further note that the link to the EFSA you kindly sent me has this to say:
“On the basis of the data presented, the Panel concludes that the evidence provided is insufficient to establish a cause and effect relationship between the dietary intake of chromium and the contribution to the maintenance or achievement of a normal body weight.”
