HealthGuru Media has closed a Series C round of financing with Castile Ventures, which is injecting $3.2 million along with existing investor Village Ventures. The company publishes an information website about medical conditions that targets the 18 to 40 year old demographic.

The company’s content library contains more than 1,000 videos covering 75+ health conditions, which currently attracts about two million visitors per month according to the company. HealthGuru claims makes that makes them the largest health video destination site with the biggest reach in its category on third-party distribution networks such as YouTube and MySpace TV.

HealthGuru is building a network of verticals based on its database of health information, chopped up into categories like pregnancy, college and sex health. The company said that it will be using the extra capital primarily for the expansion of its channels for traffic acquisition and to ramp up its money-making capabilities, which are centered mostly around advertising.
