The video discusses vitamin C from supplements, which can not only be a waste of money, but can be potentially detrimental to your health, particularly
in large doses like vitamin A, see: http://nutritionfacts.org/videos/herbalife®-supplement-liver-toxicity/ There is also evidence that rather than protecting from disease,
multivitamins can
actually increase the risk of breast cancer: http://nutritionfacts.org/videos/multivitamin-supplements-and-breast-cancer/ Also, I wouldn't put so much emphasis on one particular «superfood», because there are many others that contribute to longevity, like cocoa (but of course without the milk and sugar that many folks tend to add for palatability), see: http://nutritionfacts.org/videos/kuna-indian-secret/ and: http://nutritionfacts.org/videos/new-antioxidant-superstars-2/.
