Caffeine Anhydrous
The most active ingredient in this formula by a wide margin, at a dose worth knowing precisely before you order.
Why Caffeine Anhydrous Is in SodaSlim
A concentrated dose of caffeine, and the ingredient in this formula most likely to produce an effect you actually notice. It is one of the five named ingredients in the SodaSlim formula, included at 138 mg per capsule (Dehydrated caffeine powder), and this page covers what it is, the research context, and how that amount compares to the research.
SodaSlim publishes its amounts — and they are worth comparing
Unusually for this category, the SodaSlim label discloses every per-serving amount rather than hiding behind a proprietary blend. That is genuinely to its credit, and it lets you do something most supplements make impossible: compare what is in the capsule against what the research actually used.
Doing that comparison is revealing. The caffeine is at a meaningful dose. Several of the botanicals sit well below the amounts used in the studies they are associated with. The individual ingredient pages set out each comparison rather than glossing over it.
What Caffeine Anhydrous in SodaSlim Is
Caffeine anhydrous is simply caffeine with the water removed — a concentrated, stable powder used in supplements because it doses precisely. Chemically it is identical to the caffeine in coffee or tea.
SodaSlim contains 138 mg per capsule, plus a small additional amount from the green tea extract, which is standardised at under 3% caffeine.
For context: a typical cup of brewed coffee contains roughly 95 to 140 mg. A can of cola contains around 35 mg. So one capsule is comparable to a strong coffee, and this is the single most decision-relevant fact about the whole product.
The Research Context Behind Caffeine in SodaSlim
Caffeine is the best-evidenced ingredient in this formula, and one of the best-researched compounds in nutrition generally.
Its effects on alertness, reaction time and perceived exertion are well established and reliably reproduced. It works by blocking adenosine receptors, preventing the sleepiness signal from registering.
On weight specifically, caffeine has documented short-term effects on thermogenesis and fat oxidation — the 1989 and 1990 studies the official source cites are part of that literature. Two honest qualifications apply. The measured increases in energy expenditure are modest and do not translate into meaningful weight change on their own. And tolerance develops: habitual caffeine users show reduced thermogenic response, so the effect diminishes over the very weeks you would be taking a daily supplement.
Caffeine also has a mild, documented short-term appetite-suppressing effect, which may account for more of any experience with this product than the botanicals do.
Why Caffeine Is Included in SodaSlim, and at What Amount
It provides the energy support in the formula's positioning, and it is the ingredient most likely to produce something you actually notice.
At 138 mg the dose is functional rather than token — a real amount, chosen at roughly one strong coffee. That is a reasonable formulation decision, and considerably more honest than the trace amounts some products include purely to name the ingredient.
It also means the value comparison is straightforward: you can get this much caffeine from a cup of coffee for a fraction of the per-capsule cost. What you are paying extra for is the convenience and the four supporting botanicals.
Responsible Expectations and Safety for Caffeine in SodaSlim
Expect what caffeine does: alertness within the hour, a mild appetite effect, and a modest short-term metabolic bump that diminishes with regular use. Do not expect weight loss from it.
Safety notes, and these matter more here than on most ingredient pages. Health authorities generally consider up to about 400 mg of caffeine daily acceptable for most healthy adults. One capsule uses roughly a third of that before you have had any coffee.
Common effects at higher intakes include jitteriness, a raised heart rate, headache, digestive upset, anxiety and disturbed sleep. Caffeine's half-life is five to six hours, so an afternoon capsule is still meaningfully present at bedtime — and poor sleep works directly against appetite regulation.
The product label states it is not for anyone under 18 or for pregnant or nursing mothers; pregnancy guidance generally caps caffeine at around 200 mg daily. Anyone with a heart condition, high blood pressure, an arrhythmia, an anxiety disorder or a known caffeine sensitivity should speak to a doctor first. Caffeine also interacts with a number of medicines, including some antibiotics, antidepressants and asthma treatments.
How to read the research on this SodaSlim page
The studies described here examined individual ingredients, usually on their own, at doses set by the researchers. That research provides scientific context for why an ingredient appears in a formula.
It does not demonstrate that the finished SodaSlim product produces the same outcomes. No clinical trial of this finished formula has been published, so nothing here is product-level clinical evidence.
SodaSlim contains real caffeine — know the amount
Each capsule contains 138 mg of caffeine anhydrous, plus a small additional amount from the green tea extract. That is roughly the caffeine in a strong cup of coffee, and it is a genuine dose rather than a trace.
Practical consequences worth planning for. Count it toward your daily caffeine total — health authorities generally consider up to about 400 mg a day acceptable for most healthy adults. Take it early, since caffeine has a half-life of five to six hours and an afternoon capsule is still meaningfully present at bedtime. And expect the usual effects if you are sensitive: jitteriness, a raised heart rate, disturbed sleep or anxiety.
The product label states it is not for use by anyone under 18 or by pregnant or nursing mothers, and advises consulting a physician before use, especially if you take medication or have a medical condition. Anyone with a heart condition, high blood pressure, an anxiety disorder or a caffeine sensitivity should take that advice seriously rather than as boilerplate.

If your relationship with food or your body feels difficult
Weight-management products sit close to a genuinely hard area of life. If thinking about food, weight or your body is causing you distress, or eating patterns feel out of your control, a supplement is not the right tool and this website is not the right resource.
