HelloPharmacist Scorecard of Rhodiola Root Extract by Solgar

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This capsule contains 2 active ingredients: rhodiola powder and standardized rhodiola extract. Both forms deliver the plant's compounds.

The inactive ingredients—vegetable cellulose, vegetable magnesium stearate, silica, microcrystalline cellulose, and PhytO2X Blend—are excipients that form and stabilize the capsule.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Rhodiola product and its label doesn't state a use — see Rhodiola's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence we hold doesn't establish effectiveness for the conditions listed—altitude sickness, generalized anxiety disorder, irregular heart rhythm, athletic performance, and bladder cancer all carry an "Insufficient Reliable Evidence To Rate" rating. That means the research so far isn't strong enough to say whether rhodiola works for these uses.

The evidence, ingredient by ingredient Rhodiola

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Rhodiola is generally well tolerated for short-term use, but long-term safety hasn't been well studied. The most common side effects are dizziness and changes in saliva production—either dry mouth or excessive saliva.

The safety data advises against use during pregnancy and breastfeeding due to insufficient information.

Side effects, ingredient by ingredient Rhodiola

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Rhodiola.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 1,272 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before you take this product, double-check it with your doctor or pharmacist if you take blood pressure medications, diabetes drugs, or any medication that suppresses your immune system. Also check if you take losartan (Cozaar) or drugs that are broken down by your liver's CYP2C9, CYP1A2, or CYP3A4 pathways, or that rely on P-glycoprotein transport.

Moderate interactions are documented for the first four groups; minor interactions for the liver pathways.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Rhodiola Root Extract may be considered by people exploring its traditional uses, but because of moderate interactions with blood pressure, diabetes, and immunosuppressant medications—plus effects on liver metabolism—you'll want to check it against your specific prescriptions first. If you're pregnant, nursing, or take any regular medications, talk with your doctor or pharmacist before starting.

Rhodiola powder10 drug types · 1,271 drugs

Antidiabetes Drugs

Theoretically, taking rhodiola with antidiabetes drugs might increase the risk of hypoglycemia.
In vitro and animal research shows that rhodiola extract can decrease blood glucose due to alpha-glucosidase activity.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, taking rhodiola with antihypertensive drugs might increase the risk of hypotension.
In vitro and animal research shows that rhodiola extract inhibits angiotensin-converting enzyme (ACE) and might lower blood pressure.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, rhodiola might increase levels of drugs metabolized by CYP2C9.
In vitro research shows that rhodiola inhibits CYP2C9. This effect is highly variable and appears to be dependent on the rhodiola product studied. Also, a clinical study in healthy young males found that taking rhodiola extract 290 mg daily for 14 days reduces the metabolism of losartan, a CYP2C9 substrate, by 21% after 4 hours.

Likelihood Possible Evidence B
Immunosuppressants

Theoretically, rhodiola use might interfere with immunosuppressive therapy.
In vitro and animal research show that rhodiola has immunostimulatory effects.

Likelihood Possible Evidence D
Losartan (Cozaar)

Rhodiola might increase the levels and adverse effects of losartan.
A clinical study in healthy young males found that taking rhodiola extract 290 mg daily for 14 days reduces the metabolism of losartan, a CYP2C9 substrate, by 21% after 4 hours.

Likelihood Probable Evidence B
P-Glycoprotein Substrates

Theoretically, rhodiola might increase levels of P-glycoprotein substrates.
In vitro research shows that rhodiola inhibits P-glycoprotein. Theoretically, using rhodiola with P-glycoprotein substrates might increase drug levels and potentially increase the risk of adverse effects.

Likelihood Possible Evidence D
Antidepressant Drugs

Theoretically, rhodiola might increase the risk of adverse effects when taken with antidepressants.
A review of adverse event reports in Poland identified cases of tachyarrhythmias, myalgia, arthralgia, gum pain, restless leg syndrome, swallowing disorders, and changes in consciousness when rhodiola was taken in combination with paroxetine, escitalopram, fluoxetine, sertraline, trazodone, and/or duloxetine.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, rhodiola might increase the risk of adverse effects when taken with CNS depressants.
A review of adverse event reports in Poland identified cases of excessive sedation, myoclonus, hypotension, and hallucinations when rhodiola was taken with haloperidol, diazepam, or alprazolam.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, rhodiola might increase levels of drugs metabolized by CYP1A2.
In vitro research shows that rhodiola inhibits CYP1A2. This effect is highly variable and appears to be dependent on the rhodiola product studied. However, a clinical study in healthy young males found that taking rhodiola extract 290 mg daily for 14 days does not inhibit the metabolism of caffeine, a CYP1A2 substrate.

Likelihood Possible Evidence B
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, rhodiola might increase levels of drugs metabolized by CYP3A4.
In vitro research shows that rhodiola inhibits CYP3A4. This effect is highly variable and appears to be dependent on the rhodiola product studied. However, a clinical study in healthy young males found that taking rhodiola extract 290 mg daily for 14 days does not inhibit the metabolism of midazolam, a CYP3A4 substrate.

Rhodiola Root Extract by Solgar: Common Questions

Does Rhodiola Root Extract by Solgar interact with any medications?
Yes. Based on its ingredients, Rhodiola Root Extract has a known interaction with 1,271 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Rhodiola Root Extract contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
What side effects might I experience?
The most common are dizziness and changes in saliva production—either dry mouth or excessive saliva. Rhodiola is generally well tolerated overall, though long-term safety isn't well established.
Is it safe to take if I'm pregnant or breastfeeding?
No. There isn't enough safety data, so it's best avoided during pregnancy and while breastfeeding. Talk with your doctor or pharmacist if you're considering it.
Does this product actually work for anxiety or athletic performance?
The evidence we have isn't strong enough to say either way. Both anxiety and athletic performance carry an "Insufficient Reliable Evidence To Rate" rating.
Can I take this if I'm on blood pressure medication?
You'll need to check with your doctor or pharmacist first. Rhodiola can theoretically lower blood pressure further, which could be a problem if you're already on a blood pressure drug.
Why are there two forms of rhodiola in one capsule?
The product uses both rhodiola powder and a standardized extract. The standardized extract is processed to contain consistent levels of active compounds, while the powder provides the whole plant material.
