SodaSlim Morning vs Evening: There Is Only One Right Answer

Some dosing questions are matters of preference and this is not one of them.

The half-life arithmetic

Caffeine has a half-life of roughly five to six hours in a typical adult, longer in slow metabolisers and in anyone taking certain medications. A dose at 2pm leaves a meaningful fraction circulating at 10pm. That is enough to fragment sleep architecture even in people who fall asleep without difficulty.

Why the trade is bad

Poor sleep raises next-day ghrelin, lowers leptin and reduces spontaneous movement. In controlled studies people eat several hundred extra calories the day after a short night. Taking a thermogenic late buys you a few hours of alertness and costs you the appetite control you took it for.

The evening-training exception, which is not one

Evening trainers sometimes want the performance benefit at 6pm. The honest answer is that the cost to sleep is not worth it for a weight-management routine. Take it in the morning for the appetite benefit and use a small pre-session coffee if you must — but count it.

The rule

Morning, with or shortly after breakfast, ideally before noon and never after early afternoon. This is why SodaSlim is a morning capsule and not a flexible one. See our sleep guide for why this matters more than it sounds.
