What our research found about energy drinks

Energy drinks combine caffeine with sweeteners, vitamins and sometimes herbal or amino-acid blends, and the can sizes make the numbers add up quickly. The FDA says about 400 mg of caffeine a day is generally not associated with dangerous effects in healthy adults, and many energy drinks carry a quarter to half of that in a single can, on top of any coffee or tea. Harvard’s Nutrition Source advises avoiding sugary drinks such as sports and energy drinks, which is why zero-sugar versions dominate this shelf.

Zero-sugar energy drinks typically use sucralose, acesulfame potassium, stevia or monk fruit, and “naturally caffeinated” versions rely on yerba mate, green tea or guayusa. Caffeine and sweetener content are the two comparisons that matter. People who are pregnant, sensitive to caffeine, taking medications, or under 18 should check with a clinician or pediatrician before regular use.

What to compare

  • Caffeine per can. Compare milligrams per can against the roughly 400 mg a day the FDA cites for healthy adults, including your coffee and tea.
  • Sweetener type. Sucralose, acesulfame potassium, stevia, monk fruit and sugar all appear on this shelf.
  • Caffeine source. Synthetic caffeine versus yerba mate, green tea or guayusa; the total still counts.
  • Added extras. Vitamins, amino acids and herbal blends are added by the maker; compare the label rather than the front of the can.

Unknown and stale evidence never passes “Only show matches.” The clean score is strict and needs no setup: nine additive groups on the current label plus verified organic and sourcing claims; without them a product cannot reach 100. It is not a nutrition, allergy, or safety rating.

“Buy on Amazon” opens a reviewed product listing; “Search on Amazon” opens an Amazon search for the product, so pick the exact match yourself. Confirm the package, seller, availability, and current price before checkout. Buying links do not influence ingredient results.

01 · A closer look

Your preferences, explained.

The clean score is strict and needs no setup: nine additive groups not found in a current ingredient statement, plus a verified organic claim (and a grass-fed or pasture-raised claim for animal foods), are needed for 100; a possible match earns half and a missing claim earns nothing. Missing or expired evidence stays unknown. It does not assess nutrition, allergies, contaminants, or safety.
