Folic Acid - this inhibits uric acid synthesis - http://www.troohealthcare.com/p-1046-methyl-folate-quatrefolic-600mcg-90-capsules.aspx
Alcohol both increases uric acid production and inhibits excretion (especially beer) and should therefor be avoided. You should also drink plenty of water - at least 2 litres per day.
