I wouldn't start less than 3 tbsp per day. Remember, you're getting a ence of PA from 4-8%, or 0.9-1.8g PA from 3 tbsp of the granules. At the bottom end of the range, 2 tbsp may not get you to the 750mg that's really the minimum amount of PA you want, and I like to be sure that I'm getting this amount, even if I calculate my PA intake at 7-8% normally, not 4%. So while 3 tbsp is likely getting you around 1.8g or a little less, it can be as low as 900mg according to the many sources I've found. I'm not sure if anyone's gone over 5 tbsp per day, I wouldn't recommend it, but 5 tbsp per day seems to be a good total to shoot for. I suppose some people may take all 5 tbsp at once, but, like others have said, I'd prefer to split the dose into 3 and 2 tbsp.
