Immune System Supplements
Our selection of immune system supplements Yamamoto Nutrition is dedicated to martial arts and combat sports athletes who want to strengthen their natural defenses. Periods of intense training, weight cuts before competitions, and prolonged physical stress can weaken the immune system, exposing the athlete to a higher risk of illnesses that disrupt training continuity.
The range includes Vitamin C 1000 and PureWay® Chewable Vitamin C for daily immune support, Vitamin D and Vitamin E for strengthening defenses and antioxidant protection, and Quercetin with its immunomodulating properties. For a more targeted effect, you will find Imugen and Imugen Forte in vials, specifically formulated to boost immune response, Royal Jelly available in ampoules and capsules for natural tonic-adaptogenic support, and Spirulina rich in essential nutrients. The selection is completed by Astragalus, traditionally used to support the body's defenses, and Hericium, a medicinal mushroom with recognized immunostimulant properties. Protect your defenses so you don’t miss a single day of training.
