The bottom line No known interaction

We found no known interaction between Rhodiola and Methylene Blue in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Rhodiola and Methylene Blue

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Methylene Blue and Rhodiola in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Rhodiola safety at a glance

Rhodiola overall Use caution Generally well tolerated for short-term use, but long-term safety is not well studied.
Pregnancy Avoid Not enough safety data, so it is best avoided during pregnancy.
Breastfeeding Avoid Not enough safety data, so it is best avoided while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Methylene Blue

Interactions in our licensed database are recorded against drug classes, not just single drug names. Methylene Blue is filed under 3 classifications — serotonergic drugs, serotonergic drugs, oral drugs. Rhodiola has documented interactions with 10 drug classes — the most serious being antidiabetes drugs (moderate), antihypertensive drugs (moderate) and cytochrome p450 2c9 (cyp2c9) substrates (moderate) — and none of Methylene Blue’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

Keep it in perspective

What Rhodiola Itself Has Been Linked To

This is not an interaction — nothing below involves Methylene Blue. It is the side-effect record for Rhodiola on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Rhodiola, this list is the first place to look.

Everything above comes from the Natural Medicines adverse-effect record for Rhodiola — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Methylene Blue’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Methylene Blue column appears here.

See Every Supplement That Interacts With Methylene Blue

This page covers Rhodiola only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Methylene Blue page lists 38 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Lithium (major), 5-htp (moderate), Acetyl-l-carnitine (moderate) and Ayahuasca (moderate).

By severity: 2 major · 25 moderate · 11 minor.

From our pharmacist’s overview on the Methylene Blue page

“The pairing I would worry about first with methylene blue (Urolene Blue, Provayblue) is anything that raises serotonin, and lithium heads that group with a major rating. Methylene blue inhibits monoamine oxidase A, the enzyme that breaks serotonin down, so combining it with serotonin-boosting supplements can tip someone into serotonin…”

About Rhodiola

What is Rhodiola?

Rhodiola
  • Fatigue and low energy
  • Stress and coping (adaptogen)
  • Mental performance and focus
  • Mild depression
  • Physical and exercise performance

Rhodiola is an herb traditionally used to fight fatigue and help the body cope with stress. Some small studies suggest it may modestly reduce fatigue and improve mood, but the evidence is limited and not strong. It is generally well tolerated for short-term use, but talk to your pharmacist or doctor before trying it, and avoid it during pregnancy and breastfeeding.

Rhodiola rosea · Crassulaceae · Roots and rhizomes · Capsules, tablets, extracts, tinctures, tea

An interaction check asks whether these two react with each other — it does not ask whether Rhodiola is a good idea for someone in your situation. Here is what our Rhodiola record says about it on its own.

Rhodiola: dosing

There is no official, well-established dose for Rhodiola. Studies have used a range of amounts and different extract strengths, so it is hard to recommend one exact dose.The best approach is to follow the directions on the product label and choose extracts standardized to rosavins and salidroside. Many people take it earlier in the day because it may be stimulating.
