For those in the know, Berocca has long been the hangover cure of choice. Too bad the effervescent multivitamin is available only overseas. (Emergen-C is a Stateside favorite.) Now there's EBOOST, the brainchild of branding expert Josh Taekman and restauranteur John McDonald. Currently available in W Hotel minibars and online at eboost.com, the formula features a supershot of B-12, as much as Emergen-C, and an amino acid called s-HTP, which is said to help achieve "wellness and mental clarity," explains McDonald. Something we could, naturally, all use help finding.
