FAQs

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).

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.

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.

Food supplements are not a substitute for a varied and balanced diet or a healthy lifestyle. If you are pregnant or breastfeeding, consult your doctor before taking this supplement. Not recommended in case of hypersensitivity or allergy to any of the ingredients in the formulation, or when interactions between another product and any of its constituents are described. The recommended daily dose should not be exceeded. Keep out of the reach and sight of children. Store in a cool, dry place, away from light.
