Side effects of 5-Hour Energy

If you have pre-existing conditions like high blood pressure or heart disease, 5-Hour Energy could potentially raise your heart rate and blood pressure to dangerous levels.

Healthier energy drink alternatives
If you’re low on energy and find yourself reaching for a 5-Hour Energy or any other energy drinks, it’s important to figure out why you’re low on energy in the first place.
To have healthy energy levels, you have to prioritize sleep–especially the quality of your sleep. To do this, you must also improve the quality of your diet.
Consuming foods high in sugar and carbs can cause many energy issues. You can switch your body to fat-burning mode using a keto diet. This will provide your body with a natural, sustainable energy source called ketones.
If you want to have an energy drink, avoid popular energy drinks like Red Bull and Monster, which are loaded with sugar.
Instead, choose an electrolyte beverage that contains the most important electrolytes, including magnesium, sodium, potassium, and calcium. Electrolytes are electrically charged minerals that help to energize your cells.
Adequate magnesium intake is incredibly important for healthy energy levels. Magnesium feeds your mitochondria–mitochondria act as the cell’s energy factory. Without magnesium, you won’t have adequate energy.
Potassium is important in maintaining the energy of your cells. It keeps them charged, kind of like a battery.
When choosing an electrolyte drink, make sure that it doesn’t contain sugar or caffeine.
