Hemoglobin decrease and Rapamycin

My hemoglobin went down a lot with 1.5 mg of Rapamycin per week. I would like to increase Rapamycin to 4 mg in the future. Would supplementing with iron be advisable?

only if you feel tired, low iron levels themselves are also associated with longevity but @PDM is the expert on that


Do you mean it became lower than the normal range or is it still within the range? Mine is climbing up every month within tha range.

The lowest for 12 mo was 12.9 and the highest was 14.6. I’m on 4mg/week. Didn’t check iron for a long time.

It became lower. Hemoglobin is now at 10.6, hematocrit at 33.8. I feel great. I am not tired at all.

What was your hemoglobin before and how long in between measurements?

Supplementing with iron is a bad idea unless you have more evidence that low iron is the cause of the low hemoglobin. Get your ferritin level measured, then you’ll see if your iron is too low or not. Anyways I find it very unlikely that your hemoglobin decreased on just 1.5 mg of rapamycin weekly. Note that it could just be normal fluctuation in levels.

Yes lower is generally better for longevity, but not so low that hemoglobin drops.
