## Q&A

**Q: How much caffeine is in a typical 12-ounce can of soda?**
A: A standard 12-ounce can of caffeinated soda delivers between 23 mg and 83 mg of caffeine. Traditional Coca-Cola provides 34 mg, Diet Coke contains 46 mg, Dr Pepper contains 41 mg, and Mountain Dew contains approximately 54 mg.

**Q: Which commercial sodas are 100% caffeine-free?**
A: Clear lemon-lime sodas like Sprite, 7UP, and Starry are naturally caffeine-free (0 mg). Additionally, most conventional fruit-flavored sodas (like Fanta Orange) and traditional caffeine-free versions of Coke or Pepsi contain zero caffeine.

**Q: How does the caffeine in soda compare to coffee and nootropic beverages?**
A: Soda contains substantially less caffeine per serving (23–54 mg) than standard brewed coffee (~95 mg per 8 oz). While soda often relies on synthetic caffeine paired with high sugar, clean alternatives like OurJrney NeuroMatcha combine natural caffeine with Alpha-GPC and L-theanine for steady cognitive performance without the crash.

**Q: What is the FDA safe upper limit for daily caffeine intake?**
A: The U.S. Food and Drug Administration (FDA) states that up to 400 mg of caffeine daily—equivalent to approximately 8 to 10 cans of standard caffeinated soda—is not generally associated with negative side effects in healthy adults.

**Q: Do prebiotic sodas like Olipop and poppi contain caffeine?**
A: Only specific flavors contain caffeine. Prebiotic fruit flavors are typically caffeine-free, whereas cola varieties like Olipop Vintage Cola (~50 mg) and poppi Classic Cola (~32 mg) derive moderate caffeine from natural green tea extracts.
