Owned by a nurse and run by a staff of wellness experts, A1 Nutrition helps patrons balance their health through supplements and natural products from brands such as Natural Factors and FloraGlo Lutein. Beta carotene from Natural Factors ($22.49) sends powerful antioxidants into bodies to promote healthy skin and strengthen internal systems more effectively than a dumbbell blended into a smoothie. Customers can help set their internal sleep clocks to the correct time with melatonin from Naka ($9.99) or can sip Flora's honey-fen cough syrup ($19.99) to silence mouths' persistent barks. Eyes, lungs, and arteries battle back against free radicals with assistance from FloraGlo Lutein pills ($12.50). The body-maintenance shop also stocks cosmetic-focused items, such as Aroma Crystal's wrinkle-quencher formula ($25.99), which aims to smooth out facial lines left by years of napping on piles of unfolded laundry.
