The 90 year old woman certainly has different needs than a professional basketball player that is likely 2-3 times her weight and size. Generally speaking the recommended dietary intakes (RDA), now referred to as Dietrary Refernec Intakes (DRI) are the SAME for a person over the age of 4! There is no doubt that someone who is doing the activity of a person like Lance Armstrong, will likely require more nutrients than a couch potato. Nonetheless, the supplements that I have designed (Body Language Vitamin Co) will certainly be of benefit to thet olympic or professional athlete, but they will also be of benefit for the 18, 25, 40, 95 year old man or woman. The specific health issues, will dictate ADDITIONAL needs. Specifically, if someone has high cholesterol they will need something in addition to the supplements that I have designed. A woman also should take additional calcium to provide the DRI of 1200-1500 mg of ABSORBABLE calcium.
