“Vitamania: The Sense And Nonsense Of Vitamins” (**1/2 out of four) was an interesting, if not revelatory, documentary narrated by and starring Derek Muller about the history of vitamins and the many dangers of both vitamin deficiencies and excessive intakes in what has become a multi-billion dollar industry. Some perceptive looks at capitalism and commerce and how it has become mired in the world’s craving for nutrition and health but doesn’t tell you much that you don’t already know. Film features musical interludes also that are bizarre and unnecessary and take away from film’s serious tone. Interesting to watch as a companion piece to “Food, Inc.”
