Does rhodiola help with anxiety and stress?

That is not established. NCCIH says there is not enough reliable evidence to determine whether rhodiola is useful for any health-related purpose, and most human research is of low-to-moderate quality.

What dose of rhodiola should I take?

No dose is established. NCCIH gives none. It says rhodiola is possibly safe for up to 12 weeks. Potency varies from brand to brand, so follow the label and ask a clinician.

Can rhodiola cause insomnia?

Insomnia is a listed side effect. NCCIH names dizziness, headache, insomnia, and dry mouth or excess saliva. If rhodiola keeps you awake, stop and talk to a clinician.

Does rhodiola interact with medicines?

NCCIH reports interactions between rhodiola and losartan, a blood pressure medicine. The Merck Manual adds that rhodiola could lower blood sugar. Specific interactions with antidepressants are not established, so ask a doctor before combining it with any prescription.

Is rhodiola safe in pregnancy or breastfeeding?

Little is known about whether it is safe to use rhodiola during pregnancy or while breastfeeding (NCCIH). Ask a clinician first.

Buying Guide

Everything you need to know to make an informed decision about Rhodiola Rosea

Why It Matters

Rhodiola is popular for stress and energy, but the research is thin and potency varies. A 2026 analysis of seven US capsule products found trace amounts of arsenic, cobalt and lead in all of them, so choose a brand that publishes third-party test results.

How Rhodiola Rosea Helps You

Stress and fatigue

Rhodiola is promoted for reducing stress and increasing energy. NCCIH says there is not enough reliable evidence to show it helps for any health purpose.

Mood

Some people use rhodiola for mood. NCCIH says most human research is of low-to-moderate quality, so it cannot say whether rhodiola helps depression or anxiety.

Endurance and altitude

A 2026 meta-analysis of 9 randomized trials (424 people) found no significant effect on VO2max, and rhodiola did not prevent acute mountain sickness (OR 1.02, 95% CI 0.69-1.52).

Product quality

In a 2026 analysis of US products, rosavins ranged from 0.01% to 3.08% and salidroside from 0.07% to 2.91%, so label potency differs a lot between brands.
