SodaSlim's guidance points to at least 30 days before judging whether it's working. Here's why that window, specifically.
Caffeine acts within the hour. Green tea extract and garcinia, by contrast, are typically described as building their effect gradually over consistent daily use rather than delivering an immediate result.
Judging the whole formula after day two or three mostly measures the caffeine, not the ingredients that need more time to show anything.
Write down where you're starting — energy levels, appetite patterns, a specific number if you're tracking weight — before day one, so you have something concrete to compare against at day 30.
A minimum 30-day trial isn't marketing fluff here; it's roughly how long the slower-acting ingredients need before a fair judgment is possible.
