Rhodiola Capsules

Six-dimension breakdown

Why this scored 65/100

Rhodiola Capsules is single-ingredient capsulated Rhodiola rosea (Rhodiola rosea). Rhodiola is a Scandinavian and Russian adaptogen historically used for physical endurance and mental fatigue. The active constituents are rosavins and salidroside, both concentrated in the root. Multiple randomized trials — Cropley 2015 (life-stress symptoms), Panossian 2010 review, Ishaque 2012 meta-analysis — show modest but reproducible benefit for stress-related fatigue at 200-600 mg/day of a standardized root extract (typically 3% rosavins, 1% salidroside). Effect sizes are moderate, not dramatic. Well-tolerated in short-term trials. Mild activation possible; take before mid-afternoon. Not studied in pregnancy. Real RCT evidence base at standardized doses. Garden Organics is a small US-based single-ingredient herbal line; every product is one botanical in capsule or tincture form (no proprietary blends). Third-party COAs, per-lot heavy-metal/microbial data, and specific standardization percentages are not publicly disclosed at the product level, which is a real transparency gap despite the honest single-ingredient formatting.

Evidence & sources

The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.

Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.

How to read the Evidence dimension

• 80–100: Multiple double-blind RCTs in indexed journals directly testing this product OR the exact ingredients at the exact dose.
• 60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
• 40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
• 20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
• 0–19: No credible evidence base or unverifiable claims.
