Background The improvement in anaerobic exercise capacity associated with supplementation with creatine monohydrate (CrM) has been well established. Extracts of Russian Tarragon (RT) have been reported to produce antihyperglycemic effects [1] and influence plasma creatine levels during the ingestion of CrM [2]. Theoretically, RT ingestion may enhance creatine retention and thereby promote great...
