4
capsules of EPO-BOOST™ provides 8 grams of echinacea purpurea
Whitehead M. T., Martin T.
D., Webster M. J., & Scheett T. P. (2007). Improved running economy and maximal
oxygen consumption after 4-weeks of oral Echinacea supplementation. ACSM Annual Meeting New Orleans, Presentation Number,
908.
PURPOSE. This study
investigated the effects of four-weeks of oral Echinacea supplementation on erythropoietin,
running economy, and VO2max. Males (N = 24) were supplemented with either 8,000 mg/d of
Echinacea purpurea (N = 12) or a placebo (N = 12). Blood samples were collected prior to and
every seven days during supplementation and analyzed for erythropoietin. Maximal graded exercise
tests were administered to measure VO2max, running economy, and heart-rate
responses.
RESULTS. The Echinacea
condition significantly increased Erythropoietin at days 7, 14, and 21 and VO2max. Running
economy improved significantly in the Echinacea condition (indicated by a decrease in submaximal
VO2 during the first 2 stages of the graded exercise test).
CONCLUSION. Echinacea
purpurea supplementation results in significant increases in erythropoietin, VO2max, and running
economy.

Whitehead, M. T., (2006).
The effect of four weeks of Echinacea supplementation on erythropoietin and indices of
erythropoietic status. Medicine and Science in
Sports and Exercise, 38(5), Supplement abstract 2256.
PURPOSE.
This study determined whether four weeks of oral Echinacea purpurea supplementation resulted in
alterations in erythropoietin, red blood cell count, hematocrit, or hemoglobin. Recreationally
active males N = 24) were assigned randomly to either an Echinacea (N = 12) or a placebo (N =
12)
group. Participants were
supplemented for 28 consecutive days.
RESULTS.
Serum erythropoietin was significantly greater in the Echinacea condition than in the placebo
group at days, 7, 14, and 21.
CONCLUSION.
Echinacea purpurea supplementation for 28 days promoted a significant increase in
erythropoietin.

Echinacea supplementation significantly increases circulating erythropoietin. Medicine and Science in Sports and Exercise, 37(5), Supplement
abstract 231.
STUDY.
Healthy active males (N = 24) were assigned randomly to a placebo or an Echinacea purpurea
supplementation group. Subjects received 8 gm/day of one substance for 14 days.
RESULTS.
Erythropoietin (EPO) was 44.15% greater in the supplemented group than in the placebo
group.
CONCLUSION.
Echinacea purpurea stimulates significant EPO increases.
