B12
This vitamin may be one of the best and healthiest allies in the war against caffeine. B12 has been shown to enhance energy and boost mental clarity. When taken with a glass of ice water in the morning, it jump-starts the metabolism first thing and can provide a similar, or better, feeling than that of the usual morning coffee. There is a reason B12 is predominately found in most energy drinks -- it works. It is recommended to take B12 under the tongue for maximum absorption and effect.
Pomegranate
According to Shape, pomegranate juice is a unique and healthy alternative to coffee and other caffeine-laden drinks. Pomegranate has energy-boosting properties and is packed with antioxidants and energizers, plus its sweet, crisp flavor can be enjoyed easily by itself or blended with other juices or fruit smoothies.
Protein
Experts agree -- protein can have the same energy-enhancing qualities as caffeine, with much healthier benefits. In a recent article on Livestrong.com, simply skipping that afternoon cup of coffee or energy drink and replacing it with a serving of protein can help maintain healthy energy levels. So the next time a caffeine fix is in order, try snacking on some protein-packed nuts, seeds or white meat chicken to help power through the day.
