Iguana

Iguana comes from DRINK ID, a family-owned Polish brewery in Piotrków Trybunalski with roots stretching back to 1927. Rather than simply removing alcohol from a standard lager, they built Iguana from the ground up as a functional drink. The central selling point is amino acids — using a proprietary extraction process from brewer's yeast, the beer contains all 20 protein-building amino acids alongside dietary fibre and white mulberry extract. In the UK, Iguana is best known through Morrisons as Gym Beer, with added BCAAs and 43mg caffeine from guarana. NutriScore A-rated and certified vegan, it sits in the energy-meets-beer category at a notably accessible price point.
