Adaptogen

Rhodiola crenulata Extract (Root)

Also known as: Rhodiola crenulata, Snow Lotus, Tibetan Rhodiola, Salidroside-standardized Rhodiola

C
Evidence

Rhodiola crenulata is an alpine adaptogenic herb native to the Himalayas, standardized for salidroside content, traditionally used to support stress resilience and mental performance. Research is limited compared to Rhodiola rosea, with preliminary evidence suggesting potential benefits for fatigue and cognitive function.

Primary uses

  • Stress resilience
  • Mental fatigue
  • Physical endurance
  • Cognitive performance
  • Mood support

How it works

  • Modulation of stress hormones (cortisol, ACTH)
  • Salidroside and rosiridin bioactive compounds may enhance mitochondrial function
  • Potential monoamine neurotransmitter activity
  • Antioxidant and anti-inflammatory effects

Dosage

Typical range
300-600 mg daily (3% salidroside extract)
Timing
Morning or early afternoon
With food
Can be taken with or without food
Duration
Adaptogenic benefits typically emerge after 2-4 weeks of consistent use; some studies used durations of 4-12 weeks
Special populations
Limited safety data in pregnancy; avoid in individuals with bipolar disorder or those taking mood-stabilizing medications

Forms

  • Capsule· 70/100
  • Extract powder· 70/100
  • Raw root powder· 70/100

Safety

Common side effects

  • Generally well tolerated
  • Rare: mild headache, dry mouth, insomnia (if taken too late in day)

Contraindications

  • Bipolar disorder (potential mood destabilization)
  • Pregnancy and lactation (insufficient safety data)
  • Concurrent use with MAOI antidepressants

Evidence notes

Rhodiola crenulata has substantially less clinical research than Rhodiola rosea. Available studies are small, preliminary, or conducted in non-English journals. Salidroside standardization is rational but human efficacy data is limited. Grade C reflects moderate/preliminary evidence with promising signals but insufficient RCT evidence.

Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
