Caffeine in Sugar Reset Drops: What Guarana and Green Tea Mean for You

Yes. Two ingredients on the Supplement Facts panel are caffeine sources, even though the word "caffeine" never appears on the bottle.

Guarana seed extract sits third in the 200 mg proprietary blend. The NIH lists guarana as a caffeine source (NIH ODS: Supplements for weight loss). Green tea leaf extract sits seventh, and green tea contains caffeine too (NCCIH: Green tea).

Think of a 58-year-old woman who drinks two mugs of coffee before noon and takes a blood pressure pill. The sales page names six ingredients and skips guarana. She deserves to know her new drops add one more caffeine source to her day.

Nobody outside the company can say, because the amount is not published. Simple math still sets a ceiling.

• Two droppers give 400 mg of blend a day, shared by 22 ingredients.
• Guarana extract is only one part of that blend.
• An extract is not pure caffeine; only a share of its weight is.

So a full day of drops holds far less than 400 mg of caffeine, the amount the FDA says is not generally linked to harm in healthy adults (FDA: How much caffeine is too much). That reassures most people. It does not help the caffeine-sensitive reader, who reacts to small amounts and needs the real figure most.

1. Low Blood Glucose (Hypoglycemia). National Institute of Diabetes and Digestive and Kidney Diseases (NIH), 2021.For many people with diabetes, low blood glucose means below 70 mg/dL; it can be a side effect of insulin, sulfonylureas or meglitinides. Treat with 15 to 20 grams of glucose or carbohydrate, recheck after 15 minutes; severe lows can cause seizures or loss of consciousness and need glucagon or 911.

NIH Office of Dietary Supplements, 2026.African mango: 150 mg twice daily for 10 weeks in 102 adults, small trials by the same authors; one kidney-failure case in a person with chronic kidney disease. Forskolin: 250 mg (10% forskolin) twice daily for 12 weeks, no effect on body weight. Raspberry ketone: "not well studied". Caffeine (guarana) about 400 mg/day is safe for healthy adults. Green tea extract: liver damage is a concern. Capsaicinoids at 4 mg/day can cause stomach upset.
3. Green Tea: Usefulness and Safety. National Center for Complementary and Integrative Health (NIH), 2025.Liver injury, though uncommon, has been reported mainly with green tea extracts; high doses of green tea can lower blood levels of the beta-blocker nadolol, and interactions with atorvastatin and raloxifene are noted. Green tea contains caffeine.
