Caffeine FAQs

Is coffee healthier than energy drinks?

Generally yes, primarily because coffee contains no added sugar (unless you add it) and provides beneficial antioxidants. Energy drinks often contain high sugar levels and additional stimulants that may cause adverse effects when combined with caffeine.

Why do I crash harder after energy drinks?

Energy drinks often cause sharper crashes due to their high sugar content causing blood sugar spikes/drops, combined with caffeine's diuretic effects. Coffee's caffeine is absorbed more slowly, especially when consumed with food.

Can I mix coffee and energy drinks?

We strongly advise against mixing due to risk of caffeine overdose. A large coffee plus an energy drink could exceed 400mg caffeine quickly. Combined stimulants may also cause anxiety, heart palpitations, or sleep disturbances.

Do energy drinks hydrate you?

No, they typically dehydrate. While they contain water, caffeine is a diuretic and the high sugar content increases urine production. Coffee is only mildly diuretic when consumed regularly (the body develops tolerance to this effect).

How long do these stay in your system?

Caffeine's half-life is about 5 hours (time for half to be eliminated). So 100mg at noon means ~50mg remains at 5pm. Energy drink additives may prolong effects. Avoid all caffeine at least 6 hours before bedtime for optimal sleep.
