There are some potential downsides to some ingredients in C4. However, the effects typically occur or become problematic if the recommended daily consumption is disregarded.
High Caffeine Levels
Caffeine is great for providing a boost in energy and helping you to feel a burst of vitality for hours at a time. But too much can cause some very unpleasant side effects.
C4 contains 200 mg of caffeine in their 16 fl.oz cans. For some, this may be considered too much if you have caffeine sensitivity issues.
It’s recommended only to consume 400 mg of caffeine daily. That said, it’s best not to go overboard drinking numerous cans daily.
Too much caffeine can result in serious side effects and risks. Some include:
- The jitters
- Insomnia
- Dehydration
- Anxiety
- Headaches
- Heart palpitations
- Caffeine dependency
- Restlessness
Although C4 only contains 200mg of caffeine which is significantly less than the recommended limit, it’s still best only to limit consumption to a couple of cans per day.
It’sIt’s also best to check the can for warnings and to be sure you don’t suffer from any conditions that may be affected by C4.
Artificial Sweeteners
Artificial sweeteners are typically made out to be safe and somewhat healthy to consume. However, the artificial sweeteners in C4 have long-term effects on health that you need to beware of.
Sucralose
While there isn’t any sugar present in C4, the energy drink does contain artificial sweeteners. One of these is sucralose; although it may seem harmless, it can cause long-term health problems.
Sucralose has been deemed a great sugar alternative, but if consumed in high amounts, it can lead to the development of leaky gut and diabetes. Some other problems include:
- Increased chance of digestive issues
- May contribute to the development of certain cancers
- Creates toxic compounds if heated up
- It alters the health of your gut
- Causes GI tract problems
Overconsumption of sucralose can also lead to depression and a decrease in the good bacteria in your gut. The recommended safe amount to consume daily is 5mg for every kg of your weight.
Ace-K
Ace-K, another artificial sweetener, was approved by the FDA as safe to eat. However, just like many artificial sweeteners, this one may not be so safe.
Studies show that Ace-K can cause depression, cancer, kidney & liver problems, and headaches. Other problems include:
- Hinder appetite regulation
- Cause visual disturbance
- Disrupt blood sugar
- Interfere with metabolic processes
Keep in mind these ingredients don’t make C4 bad; only by consuming energy drinks in large quantities do these health issues potentially manifest.
Side Effects of Too Many Energy Drinks
Energy drinks in excess can cause serious health problems. So it’s crucial to monitor your intake as it’s straightforward to build a habit of drinking too many on a daily basis.
This habit can easily lead to heart problems, seizures, vomiting, and in worse cases, death.
Other side effects can lead to anxiety, headaches, heart arrhythmias, and cholesterol problems.
Essentially, a lot of energy drinks can cause overstimulation within the body. In other words, it switches on the fight or flight mode due to overstimulating the sympathetic nervous system.
This effect immediately triggers the heart, leading to a rise in blood pressure. Cellular function is also negatively impacted during this process.
Over time, this overstimulation can also lead to organ damage and an increase in inflammation within the body. In addition, some energy drinks are also loaded with B vitamins which if taken in excess, can cause blurry vision, nerve damage, skin conditions, and toxic liver.
If you have heart problems of any kind, it’s probably best to stay away from energy drinks. The condition of supraventricular tachycardia, for example, can be worsened from the beverages.
A blockage can occur in those with the heart condition. This happens due to the chemicals in some energy drinks, adenine combined with ribose.
Although there are good ingredients in C4, you should still exercise caution with any energy drink. Closely examine the warning label before consumption.
