I remember the odour was reduced to about half its strength by the 8th day. Minor improvements after that and people being less and less reactive each week. Around week 5 I think the worst was gone. Armpit smell took the longest to go. About the 6th week there was no odour in my pits or clothing. And the first 2 weeks I was less regular, then started having more complete evacuations 3rd week. The websites clearly state it takes at least 2 weeks before improvements for body/fecal odour.
Try not to think about it and see it as a long term treatment. It will work, just a question of saturating the bowels with the extract over several weeks, as well as the blood stream. This will slowly happen.
