So why do I even bother about yet another rodent study dealing with the ability of a more or less exotic flowering plant found in Benin, Cameroon, Democratic Republic of the Congo, Ivory Coast, Gabon, Ghana, Liberia, Nigeria, Senegal and Sierra Leone and its ability to boost testosterone levels?
Well, considering the fact that erectile dysfunction is a widespread disorder affecting approximately 52% of men between the ages of 40–70 years (Vitezic. 2002), some of you may actually benefit from a natural testosterone booster, specifically if the latter affects not just the mere level of testosterone, but also your libido, sperm count and erectile function. And that's three things Garcinia Cola can do.
Well, at least what scientists from the Walter Sisulu Universitty found when they used administered a Garcinia Cola (bitter cola) extract produced by extracting G. cola seeds using 70% ethanol as solvent at dosages of 200 and 400 mg/kg, i.e. 32mg/kg or 64mg/kg for human beings, based on evidence from a previous study, which demonstrated sexual behaviour improving capacity after 28 days of treatment (Ralebona. 2012). To make sure that we couldn't get away with much less the scientists added a third, lower dose of 100 mg/kg (16mg/kg for humans | learn how this is calculated).
|Figure 1: The Garcinia cola extract improved the number and success rate of ejaculations (Sewani-Rusike. 2015).|
|Figure 2: The extracts improved the mount latency, the intromission latency, the number of mounts and intromissions early, i.e. after 28 days and late, i.e. after 50 days in the study (Sewani-Rusike. 2015)|
Don't consider the dosing recommendations definitive! Even if Garcinia Cola seeds have - as traditional medicine suggests - the same effects in man, the 16mg/kg recommendation you could derive from the study at hand is nothing but a rough estimate. Without a human study to confirm that (a) Garcina Cola works and that (b) 16mg/kg is the best dosage, I wouldn't bother trying to source it over the internet.The increase in sexual performance went hand in hand with increases in testes weigh at constant prostate and epididymis and seminal vesicle weights (good news), and ~50% increases in sperm count at non-significantly improved sperm motility and viability rates (see Table 1).
