I few months ago, I posted about what a horrible meet, performance-wise, I had at short course nats this year. Couldn't figure out why I swam so slow, and why I was feeling so fatigued.
Anyway, I had a physical a few weeks later, and my blood work showed my ferritin level at 11, and my hematocrit at 39%. Both very low values for an endurance athlete. Doctor has me taking iron pills (ferrous sulfate, 325 mg, twice daily), and I've been taking Proferrin ES for about 6 weeks. Just in the last month, I've noticed a huge increase in performance. I went a :52:33 for my swim split at Ironman Boulder, and I've been feeling great in workouts. Anybody else ever experienced iron deficiency? I'm wondering if the increased performance I'm seeing is due to the replenished iron, or if it's due to something else.
Your doc is a quack. There are plenty of ways to get iron in your diet other than red meat.

As the doc explained to me, many of those iron-rich foods are non-heme iron, which is not absorbed very well. That's why I've added the Proferrin tablets (heme iron supplement). Probably doesn't help that I'm a caffeine freak, and caffeine inhibits iron absorption.
