You're getting two well-researched calming ingredients at full clinical doses. **Ashwagandha** (KSM-66 extract) delivers 600mg per serving — the top of the range used in RCTs showing reduced cortisol and perceived stress. **L-Theanine** adds 200mg, the exact single dose most studied for promoting relaxation without drowsiness.
The KSM-66 extract is a root-only standardized form with strong clinical backing for stress reduction and may also support sleep quality. L-Theanine complements it well — where ashwagandha works over weeks as an adaptogen, theanine can take effect within an hour, giving you both fast-acting and sustained support.
The two-tablet serving size is worth noting — if you take only one tablet, you're halving both doses. Ashwagandha at 300mg would still be within the clinical range, but you'd lose the full benefit of the combination at its studied doses.
