What is Caffeine Anhydrous?
Caffeine Anhydrous is caffeine with the water removed, a concentrated powder used in capsules and tablets. At 138 mg per capsule it is the largest single dose on the SodaSlim panel and the ingredient most users notice. A typical 8 oz cup of brewed coffee contains roughly 80 to 100 mg, so one capsule is about one strong cup.
The label states plainly that the product contains caffeine. The green tea extract line adds a little more (under 3% of 130 mg, or under 4 mg), and robusta green coffee extract can add a little too.
What the research shows
Caffeine is the one active here with strong evidence: it increases alertness and slightly raises energy expenditure in the short term. Whether that translates into lasting weight change is much less clear, because people adapt to regular caffeine and because eating and activity patterns matter far more.
Caffeine can also reduce appetite briefly in some people. Individual response varies a lot, which is why starting with the labeled one capsule and watching how you feel is sensible.
Safety and who should be careful
The FDA says up to about 400 mg a day is generally not associated with negative effects for most healthy adults, but sensitivity varies. Count the capsule as roughly one strong coffee in your daily total. Caffeine has a half-life of several hours, so a capsule taken late can disturb sleep. Possible effects include jitteriness, a faster heartbeat, stomach upset and headaches, and stopping abruptly after heavy use can cause withdrawal headaches. Some medicines slow how quickly the body clears caffeine, so ask a pharmacist if you take medication. The label says SodaSlim is not for anyone under 18 or for pregnant or nursing mothers.
