  • In its raw form (pharmaceutical grade; 100% pure), menthol is a stable solid white crystal.
    • Menthol is a natural compound; the (-) isomer is derived from Mentha species (i.e., peppermint, corn mint) and is associated with a characteristic ‘minty’ aroma, taste and cooling sensation6.
    • Menthol is widely used as a food ingredient to flavour confectionary, oral hygiene and medicinal products, and is unlikely to be detrimental o health and/or performance unless recommended protocols regarding frequency and concentration are exceeded.
    • Menthol is commercially available through food ingredient (e.g., Melbourne Food Depot) and chemical/laboratory materials supply ompanies (e.g., Sigma Aldrich).
  • Currently there is only one commercially available Menthol-containing product range marketed specifically as a sports product (Turbo+, Science in Sport), which is targeted for use during indoor training. However, it has limited availability for purchase in Australia, and contains other ingredients (22 g Carbohydrate, 0.01% active Menthol, 150 mg Caffeine, 1.5 g Beta-alanine, 1.5 g L-Carnitine) which may limit its use to specific sports situations.
  • Based on the current understanding of the potential benefits of L-Menthol, individuals may wish to experiment with:
    • Ingesting or mouth rinsing a menthol-containing food-grade product (i.e., confectionary such as Fisherman’s Friend - Original).
