You’ve all had those days when you are so exhausted that it feels as if you’re walking in quicksand. And the older you get, the more often you might have those days. The good news is that there are several supplements you can take to prevent those tapped out days from happening or to give yourself the turn around you need when they do.
It’s no surprise that caffeine is on the list for energy supplements. The world’s most popular “drug” not only gives you that boost you need by stimulating your central nervous system, but by encouraging your body to burn more fat for fuel. Plus, it can help to boost blood flow throughout the body for better brain function and energy delivery. Getting small doses of caffeine along with these other ingredients gives you a boost that doesn’t just drop off, but keeps you running on full.
This amino acid is a potent nitric oxide (NO) booster that promotes energy levels by enhancing blood flow. But the main way that citrulline aids energy is by enhancing the removal of ammonia from the body. Since ammonia can induce muscle fatigue, keeping its levels low helps to stave off fatigue. Common forms of citrulline include Lcitrulline or citrulline malate. Citrulline malate has the added benefit of malic acid, which further promotes energy production by helping the body convert lactic acid into energy.
This form of the amino acid tyrosine is absorbed and used better by the body than plain tyrosine. The addition of the acetyl group to tyrosine particularly facilitates its ability to pass through the bloodbrain barrier and enter the brain, where it performs the majority of its work to increase energy, elevate mood, and even aid fat loss. This is all due mainly to the fact that in the body, tyrosine is used to produce numerous hormones and neurotransmitters, including dopamine, epinephrine, and norepinephrine.
This table lists several products that contain one or more of the ingredients discussed above.
