EPO-Boost, a supplement containing various vitamins, minerals and herbal extracts, promises much through it’s name alone, but we decided to ask the questions: does it really boost endogenous EPO levels in human subjects? If so, by how much? Does it represent good value for money?
Without any double-blind randomized placebo-controlled clinical trial results to directly back their claims, we can only analyze the presence of individual ingredients as follows:
Vitamin C – low plasma levels linked to erythropoietin resistance(1), intake increases absorption of oral non-heme iron(2), improves utilization of high ferritin stores(7)(8)
Vitamin B-3 – Deficiency a.k.a. Pellagra may lead to anemia, though a direct effect is unclear(10)
Folic Acid – red cell folic acid levels known to be depleted in the same way as B6(3), plus supplementation can significantly enhance the response to erythropoietin treatment in anemic patients with chronic renal disease(4). Anemia due to folate deficiency possible.
Vitamin B12 – deficiency can lead to pernicious anemia or increase resistance to EPO(5)(6)
Iron – apart from anemia brought about by a serious deficiency, supplementation of iron is required to achieve optimal response to erythropietin treatment(8)
BodyEndurance(TM) Complex and Alpha-Lipoic Acid – the primary ingredient here, echinacea purpurea extract, was shown to increase serum EPO levels by up to 63% during a 4wk study of oral supplementation at 8g/day.(9) Out of the remaining ingredients, we are unaware of any that directly stimulate EPO levels, but the addition of these may increase the total iron content and absorption as well as oxidative stress that may limit the effectiveness of any EPO increase.
It is immediately clear that there is only one ingredient that has been clinically proven to increase serum EPO levels and that is echinacea purpurea extract. Based on a generous assumption of 2g per capsule (we are kept in the dark regarding the exact dosage, but it is the main ingredient of the BodyEndurance(TM) Complex which totals 2.1g per capsule), we can see that the total echinacea purpurea dose is in line with that of the study referenced above.
Unfortunately this study did not result in ANY change in Hemoglobin, Hematocrit or RBC count!! Although erythropoietin has other benefits which we will address in later articles, it is safe to conclude that the purpose of injecting recombinant human erythropoietin or boosting EPO levels by other means (e.g. hypoxic exposure) is normally a resultant increase in the oxygen carrying capacity of the blood via enhanced hemoglobin content.
As for the remaining ingredients, these very well might increase the effectiveness of this echinacea purpurea stimulated EPO production, but to an extent capable of significantly increasing hemoglobin content seems unlikely, unless the user is already anemic due to iron/B6/B12/folate deficiency.
When one considers the relatively cheap cost of echinacea purpurea extract bought separately and the incredibly low content of iron in EPO-Boost, we struggle to reach any conclusion other than this product is very poor value for what can only be described as a mild effects.
