How to Take It
Best taken in the evening
Sensoril is a higher-withanolide root-and-leaf extract, dosed lower (125–250 mg). Evening use is convention — no trial shows it's more sedating than KSM-66. Take it with food.
With food
Tyrosine does better on an empty stomach, but something else in this bottle needs food. Taking the whole product with a meal is the better trade — an upset stomach is why most people stop.
Keep it away from protein-heavy meals
Space it a couple of hours from Iron and Calcium
On the label
Take 2 capsules daily.
