Shaky After Eating Carbs: Many Causes and a Safety List
Feeling shaky after eating carbs has many causes, and low blood sugar of 70 mg/dL or lower is only one. Caffeine, anxiety and skipped meals can also cause it. Use the safety list, see a doctor if it repeats, and call 911 for fainting, confusion or a seizure.

Causes01
Why do you feel shaky after eating carbs?
You can feel shaky after eating carbs for several reasons, and low blood sugar is only one of them.
Mayo Clinic lists shakiness first among the early signs of low blood sugar, which it puts at 70 mg/dL (3.9 mmol/L) or lower (Mayo Clinic, Hypoglycemia). MedlinePlus lists shaking too, along with sweating and a fast heartbeat (MedlinePlus, Low blood sugar). Caffeine and anxiety can cause the same shaking, and so can missing a meal before the carbs.
We found no source in our set that links carbs themselves to shakiness. A doctor can sort it out.
Safety list02
What is the safety list for shaky spells?
The safety list is short: sit down, do not drive, check a reading if you have a meter, and note what happened.
| Do | Do not |
|---|---|
| Sit or lie down until it passes | Drive or use machinery while shaky |
| Check a reading if you have a meter | Guess your number |
| Write down the time, meal and signs | Change prescribed medicine on your own |
| Tell a doctor if it repeats | Add supplements without asking a pharmacist |
Habits03
What habits help while you wait for the visit?
Steady habits and a clear record help a doctor more than guesses.
- See a doctor about symptomsThirst, frequent urination, tiredness or blurred vision can have causes that only a blood test can sort out. (Mayo Clinic, Type 2 diabetes) (NIDDK, Diabetes Tests & Diagnosis)
- Tell them about every supplementADA and NCCIH advise telling your health care team about every supplement, herb and vitamin. (ADA, Vitamins, Minerals, and Supplements (diabetes.org)) (NCCIH, Diabetes and Dietary Supplements)
- Keep taking prescribed medicineMedlinePlus says to continue metformin even if you feel well. Never stop diabetes medicine because of a supplement. (MedlinePlus, Metformin)
- Know your numbersA1C and fasting glucose from a lab are how doctors diagnose; the cutoffs are published by NIDDK and CDC. (NIDDK, Diabetes Tests & Diagnosis) (CDC, A1C Test for Diabetes and Prediabetes)
- Keep activity and meals in the planLifestyle change is the first-line plan for prediabetes in Mayo Clinic's pages; a supplement is not a replacement. (Mayo Clinic, Prediabetes)
- Check blood pressure tooLicorice compounds and caffeine can raise blood pressure, so keep up your regular checks. (MSK, Licorice (About Herbs)) (MedlinePlus, Caffeine)
Only blood tests diagnose diabetes or prediabetes. Severe low blood sugar, fainting or a seizure is an emergency: call 911 (MedlinePlus, Low blood sugar).
The bottle04
Could Glyco Reset make you shaky?
It might, for some people, because green tea and guarana in the blend carry caffeine and the label prints no caffeine amount.
MedlinePlus says up to 400 mg of caffeine a day is generally not harmful for most adults, and that caffeine can raise blood pressure (MedlinePlus, Caffeine). We do not know how much caffeine is in a dropper. Gymnema is also in the blend. If you take diabetes medicine, show the label to your pharmacist first. Read the side effects page and the medicine check.

FAQ06
Glyco Reset questions people ask
Why do my hands shake after I eat carbs?
Common reasons include caffeine, anxiety and low blood sugar. Mayo Clinic lists shakiness as an early sign of a reading of 70 mg/dL or lower. A reading taken during the shaking helps a doctor decide.
Is shaking after a meal a sign of diabetes?
Not by itself. Only blood tests diagnose diabetes or prediabetes. If shaking repeats, tell your doctor and ask which test fits.
Can caffeine make me shaky after a meal?
Yes, caffeine can cause shakiness and a fast heartbeat. The Glyco Reset label lists green tea and guarana but prints no caffeine amount, so check with a pharmacist if you are sensitive.
What should I do if I am shaky and confused?
Confusion is a worsening sign. Get care right away, and call 911 for fainting, a seizure or signs that do not improve. Do not drive yourself.
