Heart Attack

• As with any product containing caffeine and other stimulants, one must consider the potential heart-related side effects. Caffeine has been proven to increase heart rate, increase blood pressure and in extreme cases can lead to heart attack. The potential for risk increases if the user puts additional duress on the body, which is common because of the supplements connection to exercise. Always monitor your heart rate when using Ripped Fuel.
  
  

Dizziness

• Along with cardiac-related symptoms, the caffeine and green tea leaf can cause a Ripped Fuel user to experience dizziness or light-headedness. In extreme cases where a user is pairing Ripped Fuel with high-intensity workouts, fainting and seizures have occurred, according to a report by CBS Sports.
  
  

Nausea

• TwinLabs recommends ingesting Ripped Fuel on a full stomach. The supplemental blend contains herbs and compounds known to cause stomach irritability if taken on an empty stomach. Nausea from dehydration has also been proven to be a common dangerous side-effect of Ripped Fuel, so it is important to stay hydrated when using the product.
  
  

Insomnia

• Never exceed the recommended daily allowance prescribed on the bottle of Ripped Fuel. With the main ingredients being caffeine and other stimulants, there is always a risk of sleeplessness and insomnia. It is recommended that you start with a dose smaller than what is advised on the bottle to allow your body to adjust to the compounds. If you are having trouble sleeping at night, consider reducing your dosage or taking it earlier in the day.
