Earthbar in Carlsbad's La Costa district operates inside the Equinox fitness club at La Costa Shopping Center on El Camino Real, extending a wellness-beverage and supplement concept the California brand launched in 1971. Functional smoothies blend grass-fed whey protein with adaptogenic reishi mushroom, blue spirulina, and organic acai to build workout-recovery macros in a single cup, anchoring a supplement-forward nutrition menu on the same El Camino Real health-dining corridor as Bushfire Kitchen - La Costa. Beyond blended drinks, the grab-and-go case carries cold-pressed ginger and turmeric wellness shots, pre-made salads, organic snack bars, and a curated supplement shelf stocking collagen peptides, electrolyte formulas, and plant-based protein powders. The espresso program pairs protein-boosted coffee drinks — including a Bulletproof Coffee made with MCT oil — with ceremonial-grade matcha lattes, a dual-track caffeine menu that bridges gym fuel and the single-origin craft roasting at La Costa Coffee Roasting nearby. The Power Shred smoothie delivers 30 grams of grass-fed whey alongside creatine monohydrate, L-glutamine, BCAAs, and proprietary Electro:5 electrolytes in a single 17-ounce serving.
