Even after getting a good night's rest, smashing an energizing workout, or eating energy-boosting foods for breakfast and lunch, you may find yourself needing a nap in the middle of the day.

If you're sick of feeling weary, more caffeine or an energy drink won't help. Just so we're clear: drinking coffee to get a boost of energy whenever you need it is totally fine. Caffeine acts as a nervous system stimulant, allowing you to maintain alertness and attention for a limited time. In addition, coffee is good for your heart.

For an alternative to coffee or other energizing drinks, here is a rundown of some energizing supplements that produce the same effect.

CoQ10 for cellular energy

If you're an athlete trying to boost your energy and stave off exercise-induced weariness, CoQ10 is the vitamin for you. Even if you aren't as athletic as Venus or Serena Williams, including this mineral in your wellness routine will help keep your energy up all day long.

If you're unfamiliar with CoQ10, it's time to meet your body's secret weapon in the fight against fatigue. CoQ10 helps sustain energy production for your organs and tissues, including the heart, lungs, liver, kidneys, and muscles.

L-theanine

Stressed out? The amino acid L-theanine could be the answer you've been looking for. Green tea contains L-theanine, a chemical that has been shown to reduce feelings of stress. But if you want less rest and relaxation and more focus and alertness, combine l-theanine with coffee.

B vitamins for energy production

Every aspect of your day might be influenced by general exhaustion. Good energy generation is crucial for anything from sitting at a computer all day to working out at the gym. Therefore, if you're seeking vitamins to provide you sustained energy throughout the day, maybe even reduce some tension, you'll come to trust those in the vitamin B family.
