Anti-Stress and Sleep Supplements

Our selection of anti-stress and sleep supplements Yamamoto Nutrition is dedicated to martial arts and combat sports athletes who want to better manage stress and ensure quality rest. Recovery doesn’t happen through nutrition alone: deep, restorative sleep is essential for muscle regeneration, mental clarity, and hormonal balance—factors that directly affect performance in training and competition.

The range includes Ashwagandha KSM-66®, a proven adaptogen available in capsules and tablets, ideal for reducing cortisol levels and improving resistance to physical and mental stress. To promote relaxation and sleep, you’ll find Melatovil, a liquid melatonin supplement, Gaba to support the nervous system, Regexil New Formula and Ansitex to combat anxiety and tension. The selection is completed by St. John’s Wort, traditionally used for mood support, and Neudin in convenient vials. Recover better to train better: a rested athlete is a stronger athlete.
