As well as its supposed ability to treat a wide range of conditions (ranging from fatigue to high-altitude sickness) Rhodiola rosea has also been rumoured to be able to treat erectile dysfunction (ED).
But what exactly is the correct dosage of Rhodiola rosea for ED? We look at the science behind this mysterious arctic plant to determine how much Rhodiola rosea should be taken - and if it’s even advisable to take it at all.
Taking Rhodiola rosea
Rhodiola rosea comes in the form of capsules, tablets, tinctures, and powders. The concentrations of Rhodiola rosea and its key compounds - rosavins and salidroside - may change from product-to-product, so if you are considering taking Rhodiola rosea then this is something to keep in mind.
Rosavins and salidroside have previously been believed to be the compounds responsible for Rhodiola rosea’s numerous health benefits - but more research is needed to determine whether this is the case.
Before taking any natural treatment for ED, consult your doctor to ensure it is safe for you to take as it may interact with any existing medication you are taking.
Correct dosage of Rhodiola rosea for ED
As we have already mentioned, there is little scientific evidence to suggest Rhodiola rosea is an effective treatment for ED. Most of the claims about its effectiveness come either from anecdotes or from small, poor-quality scientific studies.
Therefore, due to this lack of scientific evidence, there is also no standardised dosage recommendation for treating ED with Rhodiola rosea.
Nonetheless, one experiment showed that 26 out of 35 men with ED and/or premature ejaculation reported improved sexual function after taking 150-250mg of Rhodiola rosea a day for three months.
However, it is unclear just how effective this dosage is for treating ED, not only because this is a comparatively small trial but also because the data given also included men who experienced premature ejaculation - not erectile dysfunction alone.
Another trial of 40 participants showed that 75% of subjects experienced improved sexual performance when they took 2000mg (2 grams) of Rhodiola extract (with 2% Salidroside) once a day for one month. This large discrepancy between the recommended dosages (150-250mg in the earlier trial mentioned, 2000mg in this trial) demonstrates how poorly studied this supplement is.
And, once again, this study is of limited utility as it doesn’t mention if the participants even had erectile dysfunction.
Since there is no standardised daily dosage, it is impossible to confidently state the correct dosage of Rhodiola rosea for ED. As always, if you are seriously considering starting Rhodiola rosea, it is advisable to talk to your doctor before attempting to take it (or any other natural treatment for erectile dysfunction) as it may interact with other supplements or medications you are taking or may be unsuitable for you.
Side-effects of Rhodiola Rosea
Despite it being regarded as generally safe, Rhodiola rosea has some potential side-effects, including:
- Minor/serious headache
- Increased blood pressure
- Chest pain
The bottom line
As the current scientific evidence around Rhodiola rosea’s effect on ED is very limited, it is not possible to recommend a correct dosage of Rhodiola rosea for ED.
Some small trials have given patients doses ranging from 150mg to 2000mg, but these trials are too small and of too poor-quality to provide an accurate dosage recommendation.
