If I'm reading the package correctly, 2 tbsp powder = 6 grams = 12 caplets (I take the caplets). I've been at 9 caplets a day (4.5 g) and will up to 12 this week. I've been doing good on 9, I think I'll do better on 12.
The real question is---how do you feel? Do you feel it's been helping? Dosage probably differs with each person.
