Treeninglaager Tsitrus is the citrus entry in Põhjala's Treeninglaager line, sharing the same collaboration with Estonian track and field athlete Rasmus Mägi and the same hypotonic formulation designed to support fluid and mineral restoration after exercise. Where the original Treeninglaager takes a straightforward lager approach, this variant adds lemon juice, citric acid and natural lemon flavours, giving it a more refreshing, sharp-edged character suited to the recovery context the range is built around.
