Choline enters the nutritional limelight
By Janet Raloff
Body and mind both benefit from a dietary supplement called choline. Or so say health and nutrition stores and Web sites. They sell drinks, bars, and capsules with claims they’ll enhance physical endurance and mental suppleness.
Soon, the grocery store may be studded with banner labels extolling products as good, if not excellent, sources of choline. Eggs, red meat, and a variety of fortified foods will probably be among the first to sport such tags.
