Does Caffeine Cause Anxiety, or Make It Worse?
Caffeine and anxiety are linked: anxiety and jitters are listed effects of too much caffeine, and MedlinePlus tells people with anxiety to check with a provider first. One SodaSlim capsule, a capsule and not a drink, holds 138 mg of caffeine, 34.5% of the 400 mg daily guide for healthy adults.

Can caffeine cause anxiety?
Yes, it can. The FDA lists anxiety, jitters, poor sleep and a fast heart rate among the effects of too much caffeine (FDA, Spilling the beans: how much caffeine is too much).
Cleveland Clinic names the same early signs: jitteriness, anxiety, palpitations, headache and trouble sleeping (Cleveland Clinic, Caffeine overdose). They can feel like worry even when nothing is wrong, which is why they are easy to mistake for it.
The amount that bothers one person is fine for another. The 400 mg a day guide is for most healthy adults, not for everyone.
When is caffeine a poor fit for someone who worries a lot?
It is a poor fit when you already feel anxious, sleep badly or have been told to cut stimulants. MedlinePlus says people with anxiety should check with a provider before using caffeine (MedlinePlus, Caffeine).
Stopping suddenly has a cost too: headache, drowsiness, irritability and nausea for a couple of days (MedlinePlus, Caffeine). Cut back in steps rather than all at once.
| Situation | Step |
|---|---|
| Treated or diagnosed anxiety | Ask your doctor before any caffeine capsule |
| New jitters after a capsule | Stop it and count your coffee, tea and soda |
| Poor sleep that lasts | Stop the capsule and talk to a clinician |
| Pregnant, nursing or under 18 | The SodaSlim label says not for use |
How much caffeine is in a SodaSlim capsule?
One capsule holds 138 mg of caffeine anhydrous, which is 34.5% of the 400 mg guide. The green coffee and green tea extracts add a small unprinted amount.
Count the rest of your day before you add it. A 12 fl oz brewed coffee holds 113 to 247 mg (FDA, Spilling the beans: how much caffeine is too much), so a coffee and a capsule together can pass 250 mg quickly. Our caffeine content page has a tally, and the who it is for page covers fit.

See packsWhat signs mean you should stop and get care?
Stop the capsule and call a doctor if worry, a pounding heart or poor sleep keeps coming back. Chest pain, fainting or a racing heart that will not settle need care now.

- Yellow skin or eyes, dark urine, severe stomach painStop and see a doctor the same day. These are liver warning signs listed for green tea extract.
- A seizure or severe confusionCall 911. Seizures are reported with rapid intake of about 1,200 mg of caffeine.
- Weight loss promised no matter what you eatOne of the FTC's red flags: loss without diet or exercise, permanent loss, or blocking fat absorption.
- Jitters, poor sleep or anxiety that keep goingCut back caffeine from every source and talk to your doctor or pharmacist.
Signs from (Cleveland Clinic, Caffeine overdose) (MSK, Green tea (About Herbs)) (FTC, Seven red flags for bogus weight-loss claims). This list is not complete, and a supplement is never a reason to wait.
Keep taking prescribed medicine, and tell your doctor or pharmacist about every supplement. A supplement is not a medicine, and the FDA has not evaluated the label's statements.

FAQ01
SodaSlim questions people ask
Can a caffeine capsule trigger a panic-like feeling?
It can bring on a pounding heart, jitters and worry, all listed effects of too much caffeine (FDA, Spilling the beans: how much caffeine is too much). That feeling can resemble panic. Stop the capsule and talk to a clinician if it happens.
How long does caffeine anxiety last?
Our sources give no set time. Cleveland Clinic lists early signs and says serious ones need emergency care (Cleveland Clinic, Caffeine overdose). If chest pain, trouble breathing or confusion appear, call 911.
Does cutting caffeine ease jitters?
Less caffeine means less of the stimulant behind jitters, but our sources give no timeline. Stopping suddenly can cause headache and irritability for a couple of days (MedlinePlus, Caffeine), so step down gradually.
