To support your immune system, the main recommendation of Maharishi Ayurveda is to maintain both inner and outer balance.
Achieving outer balance can involve regular daily routine, regular meals, sufficient sleep, and a good balance between work and recreation. Inner balance can mean yoga, daily meditation, bacterial balance within your gut, and maintaining balance between the three fundamental elements or Doshas that control your body – Vata (movement), Pitta (transformation) and Kapha (structure).
Inner and outer balance can both be supported by taking advantage of the intelligence inherent in specific herbs, spices and minerals.
Maharishi Ayurveda has a number of supplements especially formulated to help you maintain balance and thereby support your immune system.
