Caffeine anhydrous in SodaSlim: how much caffeine is 138 mg, and what else counts?
Caffeine anhydrous is the fourth row on the SodaSlim label: 138 mg a capsule, so a capsule has at least 138 mg of caffeine. That is about a third of FDA's 400 mg daily reference for healthy adults (138 / 400 = 0.345), before any coffee or tea. The label says not for under 18, pregnant or nursing.

The row
What is caffeine anhydrous in SodaSlim?
Caffeine anhydrous is caffeine in dry, concentrated powder form, and it is the fourth row on the SodaSlim panel at 138 mg per capsule (SodaSlim label).
The label also prints "Contains Caffeine". The capsule has at least 138 mg, and we say "at least" because other rows add a little. The green tea row is under 3% caffeine, and 130 x 3% is under 4 mg. The green coffee row's own caffeine is not stated.
SodaSlim is a capsule, not a soda, but the caffeine is real, and it is the largest single number on the panel.
| Name on the label | Caffeine Anhydrous (138 mg) |
|---|---|
| What it is | Caffeine in dry, concentrated form. The label says 'Contains caffeine'; the capsule holds at least 138 mg, plus a little more from the tea row (under 3% of 130 mg, so under 4 mg) and whatever the coffee row holds |
| What it is sold for | Sold for energy |
| Amount per capsule (label) | 138 mg |
| Amount used in research | FDA's 400 mg a day reference for healthy adults; ACOG's 200 mg a day pregnancy limit; a meta-analysis of 13 trials |
| What the studies found | FDA says 400 mg of caffeine a day is not generally associated with dangerous effects in healthy adults, about two to three 12-ounce cups of coffee, and that caffeine in supplements counts toward that total. EFSA says single doses of 200 mg and 400 mg a day are the levels where it saw no safety concern for adults, and about 100 mg may affect sleep for some people. A 2019 meta-analysis of 13 trials (606 people) found caffeine 'might promote' weight loss, but the results varied widely between studies. One capsule is 138 mg, so coffee, tea and energy drinks on top add up quickly. |
| Main caution | Caffeine can cause jitters, a faster heartbeat, stomach upset and poor sleep, and the label says not for people under 18 or pregnant or nursing. ACOG advises under 200 mg a day in pregnancy. Use the caffeine budget tool on this site to add up your day. |
The numbers
How much is 138 mg of caffeine compared with daily limits?
It is about a third of the FDA reference and about 70% of the EFSA single-dose level.
FDA says 400 mg a day is not generally associated with dangerous effects in healthy adults, which it equates with about two to three 12-ounce cups of coffee. It adds that caffeine in supplements counts toward the total (FDA, Spilling the Beans caffeine). 138 / 400 = 0.345, so one capsule uses about 35% of that reference, and 400 - 138 leaves 262 mg for everything else.
EFSA gives 200 mg for a single dose and 400 mg a day for adults, and says about 100 mg may affect sleep in some people (EFSA, caffeine safe intakes). 138 / 200 = 0.69, and 138 is 1.38 times 100. These are reference levels for the general public, not advice for you.
| Reference | Amount | 138 mg is |
|---|---|---|
| FDA, healthy adults, a day | 400 mg | about 35% |
| EFSA, single dose | 200 mg | about 69% |
| EFSA, may affect some sleepers | 100 mg | 1.38 times |
| ACOG, pregnancy, a day | under 200 mg | about 69% |
Add up your day
How much caffeine do you get from SodaSlim plus coffee or tea?
You get the capsule's 138 mg plus every drink, so the total is yours to add up.
The cup below starts with the capsule already in it. Tap the drinks you have in a day. Amounts vary by brand and brew, so the figures are typical, not exact.

Just the capsule: 138 mg from the label's caffeine row.
1 SodaSlim capsule, pre-loaded: 138 mg (label)
Typical caffeine per serving
| Drink | Serving | Caffeine |
|---|---|---|
| Espresso shot | 60 ml | 80 mg |
| Filter coffee | 200 ml | 90 mg |
| Black tea | 220 ml | 50 mg |
| Green tea | 12 oz | 37 mg |
| Cola | 355 ml can | 40 mg |
| Energy drink | 250 ml can | 80 mg |
The 138 mg is the caffeine row on the SodaSlim label (SodaSlim label); the coffee and tea rows may add some, and the label does not say how much. 200 mg a day is the ACOG pregnancy reference (ACOG, caffeine in pregnancy); 400 mg a day is the FDA general adult reference, about two to three 12-ounce cups of coffee (FDA, Spilling the Beans caffeine). Drink amounts are typical and vary by brand. This is a counting aid, not medical advice: ask a clinician about your own limit.

The studies
Does caffeine help with weight loss?
A 2019 meta-analysis said caffeine "might promote" weight loss, but the studies disagreed widely.
It pooled 13 trials with 606 people, and the variation between them was very high (Tabrizi 2019, caffeine and weight). That means the results are not consistent enough to give a figure a reader can expect. No trial tested this capsule.
The label line is “Promotes Energy Production From Fat*”. We found no trial showing that the capsule does that, and the star leads to the FDA statement that the claim has not been evaluated.

See the priceSide effects
What are the side effects of a caffeine supplement?
Caffeine can cause jitters, a faster heartbeat, stomach upset and poor sleep, mostly as the total goes up.
FDA lists toxic effects such as seizures at about 1,200 mg taken quickly, far above the 138 mg in one capsule. The label says not to exceed the recommended dose: one capsule a day (FDA, Spilling the Beans caffeine).
Chest pain, fainting or trouble breathing: call 911. A racing heart that will not settle, or severe jitters, means stop and call a clinician.
Ask a doctor or pharmacist first if you take a thyroid, blood pressure, heart-rhythm, anxiety, depression, sleep or diabetes medicine; caffeine and green tea extract can interact with medicines (NCCIH using supplements wisely). Keep taking prescribed medicine as directed.
Who should skip it
Who should avoid caffeine supplements?

Is 138 mg of caffeine a lot?
It is about a third of FDA's 400 mg daily reference for healthy adults (138 / 400 = 0.345), and 69% of EFSA's 200 mg single-dose level. Your coffee and tea come on top.
