"Rhodiola reduces stress and mental fatigue"

Consumer advice
If you're interested in Rhodiola for stress relief, this is a legitimate product with a real ingredient. However, check the label for the actual mg dose per capsule — the page only mentions standardization (3% Rosavins, 1% Salidroside) but not the total mg. Clinical studies use 120–600 mg/day. If the dose matches, you can get nearly identical standardized Rhodiola from NOW Foods or Jarrow for roughly half the price. The subscription saves 20%, bringing it to $16.80/month — more reasonable if you plan to use it consistently. Do NOT use as a replacement for prescription anxiety medication.
