ESN has had one hell of a year, rolling out a steady stream of completely new supplements alongside multiple flavor extensions. That includes several mouthwatering additions to its top-rated Designer Protein Bar. The year isn’t finished yet, though, as the brand has quietly introduced another innovation before closing things out, introducing Mushroom Complex, expanding the ESN catalog outside of its usual performance nutrition.
Mushroom Complex brings together four concentrated mushroom extracts, each selected for balance and bioactivity. Lion’s mane is first on the list at 400mg in a 4:1 extract, for its focus and cognitive abilities. Chaga follows at 400mg, also 4:1, contributing antioxidant properties, then you have cordyceps is included at 300mg with an 8:1 ratio, while Reishi rounds things out at 240mg in a potent 10:1 extract focused on daily balance and clarity.
Altogether, ESN’s Mushroom Complex delivers a straightforward 4-in-1 formula designed to support balance, clarity, and everyday well-being. The entirely vegan supplement uses highly concentrated fruiting body extracts, all packed into a two-capsule daily serving. Mushroom Complex is available now directly through ESN, priced at €19.90 (23.36 USD) for a bottle of 60 capsules, or for a limited time, throw in the coupon “ESN” and save 20%.
