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

"I make time for a workout every day, whether it's with my trainer or squeezing in a quick session while traveling," says Handler. "Each morning, I add the Kion Aminos Powder ($55) to my protein shake to support lean muscle mass. If I'm short on time, I'll just toss the same powder into a glass of water and chug it down."

This amino powder boosts energy, reduces muscle fatigue, and supports growth with 40 percent leucine, ideal for regular exercisers.
