recent medical studies have indicated that most women do not get enough calcium and so suggest calcium supplements along with vitamin d to help with metabolizing the calcium. They have also pretty much confirmed the good benefits of Omega 3 oil. Because so much of our food unless eaten out of your own garden or farmyard, has been processed, or grown in less than fully natural methods which leads to foods generally not being as nutritionally complete, a daily multivitamin is pretty much a standard supplement, and vitamin b is for heart, circulation and red blood which all under go a certain amount of stress as a result of exercise. I take all of these, and in addition take 400 iu vitamin e, along with glucosamine chondroitin for my arthritic and discombobulated knees.
As long as you aren't taking excessivly excessive to the point of self poisoning, your body will use the amount of vitamins it needs and will excrete the rest.
The big question is whether your Dr. actually looks at your individual needs, health level, age, activity level etc. or is he/she just following the current line. I figure if the Dr. herself takes the same vitamins in roughly approximate amounts, then she probably knows what she's talking about.
Good luck with it all.
