✓Seasonal changes influence certain physiological parameters, particularly circadian rhythms and vitamin D levels.
✓In spring, the focus can be on vitality, liver support and defences against seasonal allergens.
✓In summer, antioxidants and flavonoids help manage sun exposure, whilst melatonin can occasionally help you fall asleep.
✓In autumn, probiotics, zinc and vitamin C help prepare the body nutritionally for the colder months.
✓In winter, reduced exposure to UV light very often calls for vitamin D supplementation.
