Fehling's, Benedict's and clinitest tablets are good source of copper sulphate, unfortunately they are not fit for human consumption. Apparently 85 gm of fried beef liver provides 3.3 mg of copper. Funnily enough both copper excess and copper deficiency can lead to mitochondrial dysfunction, which brings us back to CFS!!

So the advice for every body is to avoid oxidative stress during the festive period.

Subject: Oral copper supplements

Dear All,

We have had a recent case of severe copper deficiency(0.9 umol/L) presenting in a 51 year old man with neurological and haematological abnormalities which were associated with a high serum zinc level. The cause was due to excess use of polygrip false teeth fixant, containing zinc! The problem has been described before. The neurologist wants to start the patient on oral copper replacement but none are listed in the BNF. At present the patient has a preparation from a health food shop and now has a non-zinc fixant. Is there a suitable oral supplement around in the UK? I have seen copper gluconate and copper chloride mentioned in papers from the US.

Many thanks

Seasons Greetings
