<<Disclaimer: Verify this information before applying it to your situation.>> I was perusing through a reference manual from a lab and came across an article on sulphite and sulphate metabolism. There is an enzyme in the body known as PST (Phenol-sulphur-transaminase) whose function is to break down phenols. Impaired PST function could be causing the balloon-headed feelings Max has been discussing. At any rate, the article talked about an impaired sulphite enzyme function associated with asthma. Two patients were treated with molybdenum. Not only did their wheezing improve, but their PST function went up as well! The author of the article said they planned to investigate the possible tie between Mb and PST "in the next quarter." Molybdenum is found in the grains that celiacs have to give up. A couple of parents on the autism litserve have mentioned that their children seem more sensitive to phenols after going gluten-free. Perhaps supplementing with Mb might help with phenol sensitivity?
