Perguntas frequentes

What are the best supplements to boost the immune system?
The most studied nutrients for immune support are vitamin C (an antioxidant and stimulant for white blood cell production), vitamin D3 (essential for innate and adaptive immune responses), zinc (necessary for the development of immune cells), and probiotics (which strengthen the intestinal barrier, where 70% of the immune system resides).
When should I take immunity supplements?
Immunity supplements can be taken preventively throughout the year (especially vitamin D3 in autumn/winter) or in more intense doses during periods of increased stress, seasonal changes, or when the first symptoms appear. Consult a healthcare professional for personalised dosages.
Is vitamin D3 important for the immune system?
Yes. Vitamin D3 is essential for the activation of T cells and NK cells in the immune system. In Portugal, vitamin D deficiency is very prevalent, especially in winter, making supplementation particularly relevant for maintaining the body's natural defences.
