Chelsea Handler's Must Haves: From a $5 Nightcap Dessert to the Ultimate Skin Care

"Since I don't drink coffee, I rely on BrainJuice Original Peach Mango Ready to Drink Supplement ($71, originally $79 for a 12-pack) each morning for a healthy dose of caffeine," says Handler. "If I need an extra energy boost later in the day, I'll have another one in the afternoon to keep me going."

This daily supplement supports cognitive function with vitamins, amino acids, and superfoods like Alpha-GPC and organic green tea caffeine, ideal for those who prefer not to drink coffee.
