As we head outdoors to enjoy our favorite summertime fun, we may unknowingly be doing something that compromises our ability to relax. Those refreshing cold drinks – iced tea, sweet tea, cola, energy drinks – typically have caffeine. If you sometimes get the jitters after sipping icy cold caffeinated beverages throughout the day, consider taking Suntheanine as well.

Should you enjoy your favorite iced latte on a hot day?
Healthcare professionals say most healthy adults can consume up to 400 mg of caffeine a daily. That roughly equates to: 

  • Four 8-oz. glasses of brewed iced tea
  • 10 cans of cola 
  • Four cans of energy drinks 
  • 10 8-oz glasses of decaffeinated iced coffee 

But caffeine is a strong stimulant, and outdoor heat may amp up caffeine’s stimulating side effects on the body. And for some people who are sensitive to caffeine, such as those who may not be used to consuming it daily or in large quantities, those side effects can really hit you! You may feel:

  • Jittery, nervous or irritable 
  • Headachy 
  • Nauseous 
  • Unable to sleep

Reduce caffeine’s negative effects with Suntheanine
Suntheanine, a pure form of L-theanine, amplifies alpha brain waves, promoting a calm, alertness. It reduces caffeine’s negative effects such as jitters, dizziness or nausea. The general recommended ratio is 1 part caffeine to 2 parts Suntheanine. For example, for one 8-oz glass of iced tea (40 to 120 mg of caffeine), you’d want up to 200 mg of Suntheanine. 

Suntheanine may also help you get the most out of a relaxing summertime getaway by helping you feel calmer and get more sleep.
