SodaSlim Side Effects: What to Know Before the First Capsule
138 mg of caffeine, two ingredients carrying published liver-injury reports, and one nobody has studied enough. Every statement here is a federal one.

Quick answer
Most SodaSlim side effects relate to its 138 mg of caffeine per capsule, and the label asks you to consult a physician first.
FDA cites 400 mg of caffeine a day for healthy adults. Green tea extract and garcinia have published liver-injury reports, and garcinia may interact with drugs that affect serotonin.
To check your fit, see who it is for.
Start with the bottle
The label’s own caution, which on this formula is the right instruction
Start with the bottle, because on this product the bottle gets it right. The caution panel is printed in full and reads: “Do not exceed recommended dose. Not for use by individuals under the age of 18 or pregnant or nursing mothers. Consult with a physician prior to use especially if you are taking a medication or have a medical condition.”
A real caution panel that names under-18s, pregnancy, nursing and medication. On a capsule containing 138 mg of caffeine and two ingredients with published liver-injury reports, that last clause is the one to act on rather than skim.
Read the last clause again slowly, because it does more work than a reader skimming a supplement label would assume. “Especially if you are taking a medication or have a medical condition” is the correct instruction for a capsule carrying 138 mg of caffeine anhydrous alongside two ingredients with published reports of liver injury and one that NCCIH links to interactions with drugs affecting serotonin.
The largest row
Caffeine: what it does, how long it lasts, and the 400 mg line
138 mg per capsule, plus up to 3.9 mg more from the green tea row. Every figure here is FDA’s or MedlinePlus’s.
MedlinePlus: caffeine “stimulates your central nervous system”, peaks within an hour and lasts “four to six hours”. Excessive use can cause “dependency, so you need to take more of it to get the same results”, and withdrawal brings headaches, drowsiness and irritability. It also lists who should check first: people who are pregnant or breastfeeding, and people with sleep disorders, migraines, anxiety, GERD, heart arrhythmias or high blood pressure.
The numbers, and what FDA says about them
The panel prints 138 mg of caffeine anhydrous and the green tea row adds up to about 3.9 mg more. Against that, FDA cites “400 milligrams a day — that’s about two to three 12-fluid-ounce cups of coffee — as an amount not generally associated with negative effects.” So one capsule is roughly a third of that figure: a cup of coffee, in a capsule, taken every day by arrangement. The sentence that matters more than the number is the one about people rather than doses: “There is wide variation in both how sensitive people are to the effects of caffeine and how fast they eliminate it from the body.” That is why no page can tell you whether 138 mg will keep you awake; it can only tell you what the dose is, what the ceiling is, and that the distance between two people at the same dose is large.
MedlinePlus is explicit that regular use can lead to “dependency, so you need to take more of it to get the same results”, and that stopping abruptly brings headaches, drowsiness and irritability for a few days. A daily capsule is regular use.
One of two liver rows
Green tea extract and the liver
The reports cluster around extracts in capsule form rather than around the beverage, and NCCIH says so in as many words.
NCCIH: “Although uncommon, liver injury has been reported in some people who used green tea products, primarily green tea extracts in tablet or capsule form.” It notes a genetic variant carried by 5 to 15 per cent of Americans appears to raise susceptibility. Drinking green tea is not the same thing: “No safety concerns have been reported for green tea consumed as a beverage by adults.”
The variant, and the beverage
The form matters in that first sentence and it is not an accident of phrasing: the reports cluster around extracts in tablet or capsule form, which is precisely what 130 mg of a 98%-polyphenol extract in a capsule is. There is no consumer test for the genetic variant, so what the 5-to-15-per-cent figure does is set the scale — not a hypothetical concern affecting nobody, and not a common outcome either.
The beverage distinction is worth carrying away from this page because it applies to half of this category. On the drink: “No safety concerns have been reported for green tea consumed as a beverage by adults.” A concentrated extract in a capsule is a different exposure from a mug of tea, and the pattern in the case reports follows the concentration rather than the plant. NCCIH also lists the ordinary, non-serious effects of the extract: “Side effects of green tea extract supplements include nausea, constipation, abdominal discomfort, and increased blood pressure.”
The second liver row
Garcinia cambogia, the liver, and serotonin drugs
The second liver row arrives in the same capsule. NCCIH: “Numerous reports of liver toxicity have been reported in people who were taking garcinia cambogia products”, and interactions “between garcinia cambogia and some drugs affecting the liver and some drugs affecting serotonin have been reported”. If you take an SSRI, this is a pharmacist conversation.
And the scale of it: “Several cases of liver damage have been reported. Some of these cases were severe, but this appears to be uncommon.”
Serotonin drugs, a longer list than most people assume
The interaction sentence earns its own heading because of how many prescriptions it touches: “Interactions between garcinia cambogia and some drugs affecting the liver and some drugs affecting serotonin have been reported.” Drugs affecting serotonin is not a niche category — it covers SSRIs and SNRIs, among the most widely prescribed medicines in the country, along with several migraine treatments. If you take one, this is a two-minute pharmacist conversation and the label’s caution has already asked you to have it. What the row is doing on the panel is a separate question, and the federal answer is: not much. ODS says garcinia cambogia “has little to no effect on weight loss”, and the amount here is 130 mg of a 50%-HCA extract — about 65 mg of HCA, against trials that generally use a gram or more a day.
What has not been tested
Raspberry ketone, stimulants and the category
An absence of evidence is not a clean safety record, and ODS words it that way on purpose.
ODS: its “effects on body weight are unknown” and it “hasn’t been studied enough to tell if it’s safe”. That is an absence of evidence in both directions, on a fifth of this capsule by weight. In ODS’s own words it “hasn’t been studied enough to tell if it’s safe”.
That is the sentence to sit with. It is not a finding of harm and should not be read as one; it is the absence of the research that would establish either answer, attached to 130 mg of a compound that at supplement prices is made in a factory rather than extracted from fruit.
Stimulants, and the category
NCCIH, on weight-loss supplements generally: “some supplements contain large amounts of caffeine or caffeine-containing herbs such as guarana, which may cause increased heart rate and abnormal heart rhythms.” NCCIH is equally direct about how much of this shelf has been checked at all: “Many dietary supplements marketed for weight loss, including those sold as ‘fat burners’ or appetite suppressants, have not been tested for safety.” And on the word that sells more of these products than any other: “‘Natural’ does not necessarily mean ‘safe.’ For example, the herbs comfrey and kava can cause serious harm to the liver.”
NCCIH: “Many dietary supplements marketed for weight loss, including those sold as ‘fat burners’ or appetite suppressants, have not been tested for safety.” And FDA maintains a public list of weight-loss products found to contain hidden prescription drugs. SodaSlim is not on that list; it is the background this category is bought against. That list is context for the shelf rather than a statement about this bottle, and nothing here should be read as putting this product on it. NCCIH’s advice for anybody in this position is one sentence: “If you’re considering a supplement marketed for weight loss, discuss it with your health care provider.”
Silences
What the label leaves out, and the signs worth knowing
Some of what a reader needs is not a warning but a silence. These are the things this label does not say — a few of them faults, the last of them to its credit.
The label declares “Contains Caffeine” and prints 138 mg, which is correct. It does not say that FDA cites 400 mg a day as the amount not generally associated with negative effects, so one capsule is roughly a third of that before you have had a coffee.
The bottle says “daily” and stops. The morning instruction is on the listing card, not the label.
None beyond the caffeine line. There is little to declare — hypromellose is the only other ingredient — but the gluten-free and dairy-free roundels in the pack have nothing on the bottle behind them.
Extracted or synthesised is not stated, and at 130 mg a capsule the answer is almost certainly synthesised. The label does not say.
A distributor is named at a PO box. The company that made the capsules is not named at all.
Not visible on the supplied photograph. Those are normally stamped on the base after filling.
Correctly. No supplement label may promise a result, and this one does not try.
Stop and call a clinician
Unusual tiredness, loss of appetite, nausea, pain under the right ribs, dark urine, or yellowing of the skin or eyes. Any of those means stop taking the capsule and contact a clinician the same week. Both federal pages describe the liver reports behind those signs as uncommon; neither describes them as impossible, and this capsule carries two of the ingredients they concern.
The other half of the instruction comes before the first capsule rather than after it. MedlinePlus, on weight control: “Before you start, it’s important to check with your health care provider first.” On this formula that is the step which resolves most of this page at once: a pharmacist with your medication list in front of them can answer the serotonin question, the liver question and the blood-pressure question in the time it takes to read the panel out loud. NCCIH asks for exactly this: “Tell your health care providers about any complementary health products or practices you use, including dietary supplements.”
Questions
SodaSlim FAQ: safety and side effects questions
Is SodaSlim safe?
The label carries a real caution panel: “Do not exceed recommended dose. Not for use by individuals under the age of 18 or pregnant or nursing mothers. Consult with a physician prior to use especially if you are taking a medication or have a medical condition.” On this formula the last clause is the one to act on rather than skim.
How serious are the liver reports?
Both federal pages use the word uncommon. NCCIH on green tea extract: “Although uncommon, liver injury has been reported in some people who used green tea products, primarily green tea extracts in tablet or capsule form.” On garcinia: “Several cases of liver damage have been reported. Some of these cases were severe, but this appears to be uncommon.” Uncommon is not never.
What are the warning signs?
Unusual tiredness, loss of appetite, nausea, pain under the right ribs, dark urine, or yellowing of the skin or eyes. Any of those means stop and call a clinician, not wait and see.
Is drinking green tea the same risk?
No, and NCCIH draws the line explicitly: “No safety concerns have been reported for green tea consumed as a beverage by adults.” The reports concern concentrated extracts in tablet or capsule form, which is what this is.
