Rhodiola and Ashwagandha: Safe To Take Together?

Question:
Rhodiola and ashwagandha are both promoted to help with stress and anxiety. Is it safe to take them at the same time?

Answer:
Although we're not aware of a clinical study of their combined effects, rhodiola can cause dizziness and ashwagandha can be sedating -- and both may lower blood pressure, so it may be best not to take them together.  

In general, it is best to first use herbal supplements separately to assess the benefits and potential side effects you experience with each.

For more about these herbs, plus reviews and comparisons of the specific products we have tested, see our Review of Rhodiola Supplements and Review of Ashwagandha Supplements.

I have "adrenal fatigue" (often not a real condition, but in my case, thyroidectomy and hysterectomy have put burden on my adrenals)

My solution is to use rhodiola at times when I need more energy, bacopa for cognitive function, and ashwaganda for relaxation.

I do not use them concurrently, but will select at the beginning of the month, what I will need for the month.

I take both in an adrenal blend. They really help. More than anything else has

We typically use both in integrative medicine. I use ashwagandha at bedtime because it is sedating, and rhodiola in small doses in the morning because it can be activating. I tend to recommend always starting slow with natural supplements, and adding on gradually. Some people get a positive response right away and others will continue on the supplements for a couple of months, along with other stress reduction (meditation, tapping, Heartmath, Headspace app on your phone, etc.), before they feel better overall.

I've been taking both Rhodiola and Ashwaganda at relatively high dosages for some time, as well as a plethora of other herbs and what not and for the most part I have no idea if anything is working, let alone having side effects. I am not very susceptible to placebo effects. I just trust the shaky science behind these substances, using Consumerlab suggested brands wherever possible.

Hi Lawrence - Thank you for sharing your experience with this. As noted in the answer above, you may want to try each separately, so that you have a better idea of what is working, and what isn't. Also, you can find information about dosages typically used for each in the ConsumerTips sections of the Ashwagandha Supplements Review (https://www.consumerlab.com/reviews/ashwagandha_supplements/ashwagandha/#dosage) and the Rhodiola Supplements Review (https://www.consumerlab.com/reviews/rhodiola_supplements/rhodiola/#dosage).
