What Is Caffeine Anhydrous, and How Is It Different From Coffee?
Caffeine anhydrous is caffeine in its dry, concentrated form, the same stimulant found in coffee, tea and cola. One SodaSlim capsule, a capsule and not a drink, prints 138 mg of it. That is 34.5% of the 400 mg a day the FDA gives for most healthy adults, and about what a small cup of brewed coffee holds.

What is caffeine anhydrous?
Caffeine anhydrous is caffeine with the water removed, sold as a dry, concentrated powder. The molecule is the same stimulant found in coffee, tea and cola; only the form differs.
SodaSlim prints "Caffeine Anhydrous" at 138 mg per capsule, and the label adds "Contains Caffeine".
Pure caffeine powder sold loose is a different matter. The FDA warns it is dangerous, because one teaspoon can equal about 28 cups of coffee (FDA, Warning about pure and highly concentrated caffeine).
How does 138 mg of caffeine compare with a cup of coffee?
It is close to a small cup. A 12 fl oz brewed coffee holds 113 to 247 mg of caffeine, so 138 mg sits in the lower part of that range (FDA, Spilling the beans: how much caffeine is too much).
Against the 400 mg a day the FDA gives for most healthy adults, one capsule is 34.5%. The extracts add a small unprinted amount.
| Source | Caffeine |
|---|---|
| Brewed coffee | 113 to 247 mg |
| Energy drink | 41 to 246 mg |
| Green tea | 37 mg |
| One SodaSlim capsule | 138 mg, plus a little from the extracts |
Is caffeine in a capsule different from caffeine in a drink?
The caffeine itself is the same; the pattern is different. A drink is sipped over time and you can see what you pour, while a capsule delivers it all at once.
That makes counting easier to forget. Add the capsule to your usual coffee and tea before you pour a second cup. Too much caffeine can cause a fast heart rate, jitters and poor sleep (FDA, Spilling the beans: how much caffeine is too much).

See packsHow do you fit a caffeine capsule into your day?
Count first, then take one capsule, then stop adding stimulants as the day goes on.
- 1Morning: check, then one capsule
The label says one capsule daily and prints no time. The seller's copy prefers the morning. Do not take more than the label says.
- 2Count your first cup
Coffee, tea or an energy drink adds to the capsule's 138 mg. Brewed coffee runs 113 to 247 mg per 12 fl oz. (FDA, Spilling the beans: how much caffeine is too much)
- 3Midday: food and movement you already plan
A walk or a meal does the work that no capsule can; a gradual pace of 1 to 2 pounds a week is what Mayo Clinic and the CDC describe. (Mayo Clinic, Weight loss: 6 strategies for success) (CDC, Steps for losing weight)
- 4Afternoon: stop adding stimulants
Insomnia and jitters are listed effects of too much caffeine. Late coffee, tea or soda on top of the capsule is the common way to overshoot. (FDA, Spilling the beans: how much caffeine is too much) (Mayo Clinic, Caffeine: how much is too much)
- 5Night: sleep and notice
Note sleep, heartbeat and mood. Racing heart, chest pain, yellow skin or eyes, or dark urine: stop and call a doctor. (MSK, Green tea (About Herbs)) (MedlinePlus, Caffeine)
An illustration of a habit: the label sets only "one capsule daily". Times are suggestions, and prescribed medicine keeps its own schedule.
Ask a doctor first if you are pregnant, nursing, or have a heart rhythm problem, high blood pressure or anxiety. Keep taking prescribed medicine. Our caffeine content page and caffeine anhydrous page go further.

FAQ01
SodaSlim questions people ask
Is caffeine anhydrous stronger than the caffeine in coffee?
No, the molecule is identical. What differs is concentration and form: dry caffeine is packed to an exact weight, while coffee varies by cup. SodaSlim's 138 mg is inside the 113 to 247 mg range of a 12 fl oz brewed coffee (FDA, Spilling the beans: how much caffeine is too much).
Is caffeine anhydrous natural or synthetic?
The SodaSlim label does not say. It prints only "Caffeine Anhydrous" and the amount. Either way the caffeine acts the same.
Can you overdose on caffeine anhydrous?
Yes, mainly with loose powder. The FDA warns that a teaspoon of pure caffeine can equal about 28 cups of coffee (FDA, Warning about pure and highly concentrated caffeine). A capsule holds a fixed amount, but taking more than the label allows adds up fast.
