If you were to take a 1/4 cup of coffee for a boost, and it didn't work, would you try again in 6 hours and then again the next day and the next until you ran out of coffee? By then you'd say, "coffee doesn't work - screw that wholistic stuff." Why do we do the same thing for herbal supplements then? If it were a tea, you would just make it stronger, but because it comes in a capsule, you think you should just do what the bottle says.
50mg of Withanolides is about a cup of coffee for things like anhedonia, apathy, and the mid-day slump. For KSM-66 (5-6%), that's 3x 300mg pills. For Sensoril (8-10%), that's 2x 300mg pills. For the 1.5% extract, you would need over 3 grams. This stuff is so watered down half the time, it's not even funny. Here is a photo from an Indian brand I found:
This is the first time where I actually agree with the instructions on the package on how to dose Ashwagandha. It's from the country where it is grown, so... just saying... they should know it's safety just from anecdotal experience.
Don't drink the watered down coffee, and don't dose your Ashwagandha like you don't know what's good for you.
50mg of withanolides. Do the math.
