Effects of short-term ingestion of Russian Tarragon prior to creatine monohydrate supplementation on whole body and muscle creatine retention: a preliminary investigation

This is an excerpt from the content

Background

It has been well-established that creatine monohydrate (CrM) increases whole body creatine retention and muscle creatine content. Extracts of Russian Tarragon (RT) have been reported to produce anti-hyperglycemic effects [1] and influence plasma creatine levels during the ingestion of CrM [2]. Theoretically, RT ingestion with CrM may promote greater creatine retention than ingesting CrM alone. The purpose of this preliminary study was to determine if short-term, low-dose aqueous RT extract ingestion prior to CrM supplementation influences whole body creatine retention or muscle creatine content.

Methods

In a double-blind, randomized, and crossover manner; 10 untrained males (20±2 yrs; 179±9 cm; 91.3±34 kg) ingested 500 mg of aqueous Tarragon extract (Finzelberg, Andernach, Germany) or 500 mg of a placebo (P) 30-minutes prior to ingesting 5 g of CrM (Creapure®, AlzChem AG, Germany) (CrM+RT). Subjects ingested the supplements two times per day (morning and evening) for 5-days and
