The ultimate guide to immune health

Olive Leaf Extract (Olea europaea) This potent antioxidant contains oleuropein, a nutrient which eliminates free radicals and prevents cell damage, reduces inflammation and boosts immunity, along with reducing the

risk of cardiovascular disease. Olive leaf extract is highly antimicrobial, inhibiting the growth of many pathogenic microorganisms.

Andrographis (Andrographis paniculata) This herb possesses valuable immunostimulant properties, acting as an antibacterial, antimicrobial and anti-inflammatory agent in the body. Long used in Ayurveda, the traditional medical system of India, modern research has validated the use of andrographis in treating colds and flu, lowering fever, managing inflammation, reducing osteoarthritis-caused pain, swelling and stiffness, improving cartilage production and helping with allergies.

Selenium This trace mineral is a high-potency antioxidant, helping to protect cells from the free radicals which cause heart disease, stroke, mental decline and premature ageing. Selenium is a precursor to glutathione peroxide, which improves immune system function in the body naturally; it also plays an important role in thyroid health and the metabolism.

Zinc , a powerful mineral, plays a crucial role in enhancing the immune system. However, vegans and vegetarians may face a shortage of this mineral as its primary sources are usually derived from meat, such as beef liver and oysters. Fortunately, zinc can also be found in resonable quantities in mushrooms, whole grains, nuts, peas, and sea vegetables.

Vitamin D Low levels of vitamin D have been associated with compromised immune function, osteoporosis, arthritis, inflammatory bowel disease, chronic muscle and joint pain, seasonal affective disorder, and hypertension. Studies suggest that individuals who maintain optimal blood levels of vitamin D experience better bone and tooth health, improved calcium retention, and less pain and depression. Foods rich in vitamin D include oily fish (such as salmon, sardines, and tuna), egg yolks, beef liver, fortified milk, and mushrooms.
