Quercetin in Energy Drinks
Quercetin is the inspiring ingredient in FRS Energy Drinks. FRS Energy Drinks were created to help people avoid getting tired while working out. To do this, the drink called on queretin's ability to naturally boost the body's mitochondrian production. FRS advertises quercetin's ability to "provide sustained energy, increased endurance, [and] immune system support." One serving of FRS is equal to eating 40 apples. FRS claims there have been suffiecient studies to back up their claims, but most other sources say there has not yet been enough research to draw any conclusions. Possible negative side effects include headaches, and tingling of the eyes and legs and when taken with antibiotics, quercetin could decrease effectiveness. Extreme doses (more than 772mg per day) could cause kidney damage. FRS only averages 325mg per serving.

Quercetin is naturally and most commonly obtained through fruits and vegatables:

  • apples
  • blueberries
  • onions
  • parsley
  • sage
  • tea
  • red wine
  • cauliflower cabbage

Flavanoids help to give fruits their pigments. Because quercetin is a flavanoid, it is often found in the skins of apples, the skin being the part that has color.
