Shoden ashwagandha (high-withanolide)

Tier 3 — weak evidence · Sleep · Stress · Adaptogen

An ultra-concentrated ashwagandha extract (35% withanolides) roughly 7x more potent per mg than KSM-66. A single RCT found 120 mg improved sleep quality and stress scores, but replication is lacking. Long-term safety data is limited compared to KSM-66. The standard extract has a far stronger evidence base. Use conservatively and cycle off regularly.

Dose: 120 mg/day Shoden extract; less long-term safety data than KSM-66 — cycle conservatively
