Abstract
This study was based on in vitro observations that naringin isolated from grapefruit induced red cell aggregation and evidence that clumped red cells are removed from the circulation by phagocytosis. The effect on hematocrits of adding grapefruit to the daily diet was determined using 36 human subjects (12 F, 24 M) over a 42-day study. The hematocrits ranged from 36.5 to 55.8% at the start and 38.8% to 49.2% at the end of the study. There was a differential effect on the hematocrit. The largest decreases occurred at the highest hematocrits and the effect decreased on the intermediate hematocrits; however, the low hematocrits increased. There was no significant difference between ingesting 1/2 or 1 grapefruit per day but a decrease in hematocrit due to ingestion of grapefruit was statistically significant at the p less than 0.01 level.
PROOF
This is something that has worked for me along with proper hydration (note drinking to much water can dehydrate you by eliminating essential minerals).
My RBC on 3/15 @ 1:04 pm was @ 6.04
Hematocrit 54%
Hemoglobin 17.6
On 3/16 for breakfast ate �½ grapefruit along with my usual rye/oatmeal 4egg whites 1 whole egg with a little extra iodized salt for a hydration support.
I repeated this protocol for one week and had another blood draw on 3/23 @ 9:06 am my RBC were
RBC 5.80
Hematocrit 50%
Hemoglobin 17.1
I'm also on TRT, for the last four years.
Yes my BP dropped as my HR did also
