Caffeine isn’t the only way for your body to summon an extra boost of energy. According to integrative neurologist Ilene Ruhoy, there are a lot of plant-based foods you can eat that have a “high consumption of compounds that enhance energy production of cells.”

Below, you’ll find a list of the best energy-enhancing compounds and the foods you can eat in order to benefit from them.

Lycopene: This compound provides antioxidant effects, and is known to give fruits and veggies their red-orange color. You can find lycopene in carrots, watermelon, tomatoes, and grapefruit.

Phlorizin: Studies suggest this polyphenol can help manage blood sugar levels. Eating red apples will give you a good dose of phlorizin.

Betaine: With its ability to support healthy liver function and reduce inflammation, betaine is a powerful energy-boosting compound. Beets, spinach, and goji berries are known to have betaine.

Catechins: These are a group of antioxidant polyphenols with anti-inflammatory and immune-supporting benefits. They are also known to prevent cell damage. Eat green grapes, green tea, kiwi, and persimmons to source catechins.

Hesperidin: This fruit-based compound has been shown to lower blood pressure and support the vascular system. Enjoy citrus-like limes, oranges, and lemons to get a hesperidia-based energy boost.

Citrulline: An amino acid, citrulline can help reduce blood pressure in adults with hypertension and boost athletic performance. You’ll find this compound in watermelon (including the rind).

Rutin: Studies suggest that this antioxidant may protect against neurodegenerative diseases like Alzheimer’s and dementia. Rutin can be sourced from apples, nettle, buckwheat, apricots, cherries, and plums.

Keeping your body energized isn’t just a matter of drinking cups of coffee. Good sleep, exercise, and a healthy diet containing energy-boosting plant-based compounds can all help you get through the day without feeling that mid-afternoon slump.
