CBC blood test resuslts Hemoglobin levels

Mar 20, 2011
Los Angeles
This is an old thread but still interesting. For posterity here's my contribution: I just had a blood test done as part of a check-up, hematocrit was 49%, fully hydrated. The nurse said my RBC was very high as well but I forget what it was. I don't have any other basis for comparison as far the hematocrit level.

I am currently spearing once or twice a week, and if I only get in the ocean once during a week I try and do 15-25 minutes of apnea bike, so basically I'm training twice a week, which seems to be just enough to maintain apnea performance on a subjective level. On most non diving/apnea days though I go to the gym though and do resistance training and frequently interval cardio. Diet-wise I eat very healthly--lots of protein, not much alcohol, whole foods, amino acid supplements, and two or three times a week I take an iron supplement (Schiff Women's Health, 18mg iron+).

You need more than iron though. To build blood and myoglobin you need:
- Iron (54 mg per day)
- B12 (sublingual methylcobalamin 5000mcg once per day)
- Folic acid (5000mcg per day)
- B6 (50mg+ per day)
- Vitamin C (500mg+ per day)
[another excellent supplement is to take dessicated liver tablets at the same time as your iron tablets, it increases absorption]
Hi Eric. I am a little bit confused about the supplement of B12. Are you sure we are talking about 5000 mcg and not about 5 mcg per day?
Thank you.
