GET YOUR VITS IN

While vitamin D is usually associated with bone health, over the last decade numerous studies have shown an association with immune health. It’s been noted that during winter, when vitamin D levels are at their lowest due to lack of sunlight – and the inability to produce vitamin D within the body – infection and illness rates, particularly upper respiratory infections, are at their highest. Supplementation with vitamin D is encouraged in the northern hemisphere during the winter months, to maintain optimal immunity. Doses vary, but most people will benefit from taking 1,000iu per day.

Vitamin E deserves a mention, too. A powerful antioxidant, it has a direct effect on destroying free radicals, as well as naturally enhancing the immune system. The best sources include nuts, seeds and dark-green vegetables, such as spinach and broccoli.

Vitamin C is another potent antioxidant. While there are numerous products on the market promoting high-strength vitamin C to boost your immune system, studies show that dietary options are better absorbed. Good sources include citrus fruit, strawberries and the skin of potatoes.
