Need a midday boost? Plant-based stimulants like yerba mateé, tea (Camellia sinensis), chlorella, and rhodiola lend long-lasting fuel in pint-sized packages. These top picks use sweeteners such as stevia and fruit extracts (and limit any sugars—even those from natural sources like fruit—to fewer than 10 grams); plus, they’re free from artificial colors and flavors and excess calories. Look for extra health perks like high amounts of immunity-boosting vitamin C.
