Hello, my name is Dr.Dorina Gurabardhi. I read carefully your questions.
Some advices that I can give to you for energy are:
-Consume caffeine. It revs up your
metabolism and makes you feel like you have more physical and mental energy.
-Consume guarana. This herb contains caffeine.
-Asian
ginseng. It may improve mood and energy.
-Take supplements of
Vitamin B12 if you are not.
-energy comes from calories, so you might want to have a healthy snack, like almonds and fruit, or yogurt with granola.
-Stay hydrated, aglass or two of water can make a big difference in energy if you’re low on fluids.
Hope my answer was helpful, if you have any other questions I'll be glad to help, thanks!
