I take daily supplements. I take a women's formula multi-vitamin that gives me 100% of everything as a base. But 100% of the RMD is not enough for calcium & iron, so I take extra of those. I need extra calcium because of my age, and I need extra iron because I am deficient. Apparently new research shows that cyclists need more iron for the same reasons they need more calcium. Then I get everything else from food. I feel the vitamins give me a good starting point, but I use up more than the average because I am actively engaged in a sport that makes higher demands on my body's resources. Results from bloodwork last year proved that to me. Otherwise, no pills unless truly needed.
