Monday Ingredient Spotlight: Ashwagandha KSM-66 vs Sensoril
The question of "Which ashwagandha should I take, KSM-66 or Sensoril, Dr D.?" has come up a few times lately, so I wanted to squeak into your inbox with a quick rundown: what ashwagandha does, why the type matters more than the brand, and how to match it to what you're actually after.
Ashwagandha (Withania somnifera) is an adaptogen used for centuries to steady the stress response. Modern practice leans on standardized extracts - and the useful distinction isn't the patented brand name on the bottle. It's the withanolide concentration, the dose, and when you take it.
Match the extract to the goal:
🔹 For focus + stamina: lower-concentration root extracts (~5% withanolides), taken in the morning, help with daytime stress, cortisol, and energy.
🔹 For rest + sleep: higher-concentration extracts (~10%+), at higher doses in the evening, especially at ≥600 mg/day for at least 8 weeks, are calming and supportive of sleep.
It comes down to the goal and the clock:
Want daytime energy, focus, and performance? Reach for a lower-concentration extract in the morning. Want to come down from the day and sleep well? A higher-concentration, higher-dose extract in the evening is the better fit. |
Same herb - different job, depending on how it's standardized and dosed.
