Karlie Kloss's Must Haves: From a Memory Supplement to a Headspace Subscription

Motherhood has arguably had the greatest impact on Kloss's wellness routine. "Now with two kids, I feel like I need to be even more efficient and effective with the time that I set out to exercise or the ingredients that I'm putting in my body," she explains. After struggling with postpartum brain fog, Kloss now swears by this Thorne Memoractiv Supplement ($66) for improving cognitive function.

Pro Tip: This sleep supplement features a blend of ashwagandha and ginkgo. For best results, take two capsules daily ahead of your normal bedtime.
