Most likely
What are the most common side effects of Sodaslim?
The most common side effects are caffeine effects: feeling jittery, a faster heartbeat, trouble sleeping, an upset stomach and headache. Each capsule has about 140 mg of caffeine; the exact total is not printed.
The FDA lists these as signs of too much caffeine (FDA: How much caffeine is too much). Mayo Clinic adds nervousness, irritability, frequent urination and muscle tremors (Mayo Clinic: Caffeine limits). Regular coffee drinkers may notice little, because tolerance builds (NIH ODS: Weight-loss supplements (consumer)).
- Restlessness, shakiness or a jittery feeling
- Trouble falling or staying asleep
- Faster heartbeat or a pounding feeling in the chest
- Upset stomach, heartburn or nausea
- Headache, dizziness or peeing more often
A morning capsule, as the sales page suggests, protects sleep. Caffeine's half-life in adults is about 5 hours (StatPearls: Caffeine).
Ingredient by ingredient
Which Sodaslim ingredient causes which side effect?
Caffeine explains most short-term effects. Green tea extract and garcinia carry the rare but serious liver concern.
| Ingredient (per capsule) | What agencies and studies report | Source |
|---|---|---|
| Caffeine anhydrous (138 mg) | Jitters, fast heartbeat, raised blood pressure, insomnia, anxiety, upset stomach, headache | (FDA: How much caffeine is too much) (MedlinePlus: Caffeine) |
| Green coffee bean extract (130 mg) | Headache and urinary tract infections in trials; adds a little caffeine | (NIH ODS: Weight-loss supplements (HP)) |
| Raspberry ketone (130 mg) | Not studied enough in people to know if it is safe | (NIH ODS: Weight-loss supplements (consumer)) |
| Garcinia extract (130 mg) | Gut upset more common than placebo in one trial; rare liver injury; 3 mania reports | (Onakpoya 2011: Garcinia meta-analysis) (LiverTox: Garcinia cambogia) (NIH ODS: Weight-loss supplements (HP)) |
| Green tea extract (130 mg) | Nausea, constipation, belly discomfort, raised blood pressure; uncommon liver injury | (NCCIH: Green tea) (LiverTox: Green tea) |
Caffeine and medicines
Does Sodaslim interact with medicines?
It can, mainly through its caffeine. MedlinePlus says caffeine interacts with other stimulants, certain antibiotics, asthma medicines and heart medicines (MedlinePlus: Caffeine). Green tea extract adds a few more.
| Medicine or substance | What can happen | Source |
|---|---|---|
| Ephedrine medicines, ephedra or ma huang | Do not combine: risk of high blood pressure, heart attack, stroke and seizures | (Mayo Clinic: Caffeine limits) |
| Other stimulants, pre-workouts, energy drinks | Stacked stimulant effects: racing heart, jitters, poor sleep | (NIH ODS: Weight-loss supplements (consumer)) (MedlinePlus: Caffeine) |
| Tizanidine (muscle relaxant) | Avoid the combination | (StatPearls: Caffeine) |
| Bupropion | Use caution: both can lower the seizure threshold | (StatPearls: Caffeine) |
| Some antidepressants, antipsychotics and anti-anxiety drugs | Interactions through the liver enzyme CYP1A2 | (StatPearls: Caffeine) |
| Certain antibiotics, asthma and heart medicines | Interactions reported with caffeine | (MedlinePlus: Caffeine) |
| Nadolol, atorvastatin, raloxifene | Green tea may lower nadolol and atorvastatin levels; raloxifene interaction reported | (NCCIH: Green tea) |

Word for word
What cautions does the Sodaslim label print?
CAUTION/WARNING: 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. KEEP OUT OF REACH OF CHILDREN. DO NOT USE IF SAFETY SEAL IS DAMAGED OR MISSING.
The label also flags: "Contains Caffeine".
Caffeine math
How much caffeine is too much with Sodaslim?
For healthy adults, the FDA says up to 400 mg a day from all sources is not usually linked to harm (FDA: How much caffeine is too much). One Sodaslim capsule uses about a third of that. Coffee, tea, soda and energy drinks fill the rest quickly.
| Your day | Total caffeine | Against the 400 mg limit |
|---|---|---|
| 1 capsule only | About 140 mg | Well under |
| 1 capsule + 1 brewed coffee | About 253 to 387 mg | Under, but close at the high end |
| 1 capsule + 2 brewed coffees | About 366 to 634 mg | Can go over |
| 1 capsule + 1 energy drink | About 181 to 386 mg | Under, but check the can |
| 2 capsules (against the label) | About 280 mg | Leaves little room for anything else |
Never take extra capsules to catch up. The FDA warns that taking in about 1,200 mg quickly can cause seizures (FDA: How much caffeine is too much). Our Sodaslim caffeine guide shows how to count a full day.
Stomach and gut
Can Sodaslim upset your stomach?
It can. Caffeine increases stomach acid (MedlinePlus: Caffeine), and green tea extract users report nausea, constipation and belly discomfort (NCCIH: Green tea). In one garcinia trial, gut side effects were twice as common as with placebo (Onakpoya 2011: Garcinia meta-analysis).
People with acid reflux or ulcers should ask a doctor first, as MedlinePlus advises for caffeine (MedlinePlus: Caffeine).
Liver signs
Can Sodaslim affect your liver?
Rarely, through two of its extracts. LiverTox rates green tea extract a well-established cause of liver injury, with over 100 cases (LiverTox: Green tea), and garcinia a likely but rare cause (LiverTox: Garcinia cambogia). Sodaslim's amounts are low compared with the case reports, which lowers exposure but does not remove the risk.
Dark urine
Urine the color of tea or cola.
Yellow skin or eyes
Often first seen in the whites of the eyes.
Belly pain or nausea
Upper right belly pain or nausea that lasts.
Unusual tiredness
New fatigue with no clear cause.
Stop Sodaslim and see a doctor promptly. Green tea extract injury usually starts 1 to 6 months after starting (LiverTox: Green tea); garcinia injury usually within 1 to 4 weeks (LiverTox: Garcinia cambogia).
Who should not
Who should not take Sodaslim?
The label rules out anyone under 18 and pregnant or nursing women. It asks anyone on medication or with a medical condition to consult a physician first.
In pregnancy, ACOG advises under 200 mg of caffeine a day (ACOG: Caffeine in pregnancy), and caffeine's half-life can reach 15 hours late in pregnancy (StatPearls: Caffeine). MedlinePlus says to check first with sleep disorders, migraines, anxiety, reflux, heart rhythm problems or high blood pressure (MedlinePlus: Caffeine). Mayo Clinic adds seizure disorders (Mayo Clinic: Caffeine limits). The who Sodaslim is for page covers fit in more detail.
Quick check
Should you ask a doctor before taking Sodaslim?
Five questions. A yes on any of the first four means talk to a doctor first.
The checklist follows the label's caution panel and caffeine guidance from the FDA and MedlinePlus. It is not a diagnosis.
When to act
When should you stop Sodaslim and get help?
Stop and get urgent care for chest pain, a racing or irregular heartbeat, fainting or a seizure. Stop and see a doctor soon for any liver sign above, or side effects that do not settle within a few days.
Stop the capsules
Wait for a doctor's advice before taking another.

FAQ
Sodaslim side effects: common questions
What are the side effects of Sodaslim?
The main Sodaslim side effects are caffeine effects: jitters, faster heartbeat, poor sleep, upset stomach and headache (FDA: How much caffeine is too much). Each capsule has about 140 mg of caffeine. Green tea extract and garcinia have rare liver-injury reports (LiverTox: Green tea) (LiverTox: Garcinia cambogia), so watch for dark urine or yellow eyes.
Does Sodaslim cause insomnia?
Yes, if taken late or with other caffeine. Caffeine's half-life is about 5 hours in adults (StatPearls: Caffeine), so an afternoon capsule can still be active at bedtime. Take it in the morning and skip coffee, tea and soda after early afternoon.
Can Sodaslim raise your blood pressure?
It can, a little. Caffeine raises blood pressure (MedlinePlus: Caffeine), and green tea extract has been linked to raised blood pressure (NCCIH: Green tea). If you have high blood pressure, ask your doctor before starting and check your readings during the first weeks.
Is Sodaslim safe with antidepressants?
Ask your doctor or pharmacist first. Caffeine is broken down by the liver enzyme CYP1A2 and interacts with some antidepressants, antipsychotics and anti-anxiety drugs (StatPearls: Caffeine). Bupropion needs extra caution because both it and caffeine can lower the seizure threshold.
Does Sodaslim cause anxiety or a racing heart?
It can in caffeine-sensitive people. The FDA lists anxiety, a fast heart rate and palpitations among signs of too much caffeine (FDA: How much caffeine is too much). Stop and get medical care for chest pain, fainting or a heartbeat that stays fast or irregular.
Should I tell my doctor I take Sodaslim before surgery or blood tests?
Yes. The FDA says supplements can interfere with lab tests and cause problems during surgery (FDA 101: Dietary supplements). Tell your doctor about Sodaslim well before any procedure.
