The Só Verde Immune System collection brings together natural foods and food supplements chosen for everyday immune support — from vitamin D, vitamin C and zinc to antioxidant superfoods, omega-3 and immune-friendly essential oils. Whether you are preparing for the colder months, rebuilding your energy, or simply reinforcing your daily routine, this page helps you compare the main options and choose what fits your needs. All prices are in euros, with fast delivery across Portugal.

Which nutrients support the immune system?

Your immune defences rely on a steady supply of specific vitamins and minerals. Under EU-authorised health claims, vitamin C, vitamin D, vitamin A, vitamin B6, vitamin B12, folate, zinc, selenium, copper and iron all contribute to the normal function of the immune system. Vitamin C and zinc are among the most studied for everyday resistance; vitamin D matters most during the low-sunlight autumn and winter months; and selenium and copper help protect cells from oxidative stress. A varied diet, good sleep and regular movement remain the foundation — supplements and superfoods are there to fill the gaps when intake falls short.

What you will find in this collection

  • Vitamin D formulas — including Vitamin D-3 & K-2 and high-strength D3 5000 IU, popular for autumn and winter.
  • Vitamin C and zinc — buffered vitamin C complexes and zinc formulas for daily immune resistance.

Frequently asked questions

Which nutrients support the immune system?
Vitamin C, vitamin D, zinc, selenium, copper, vitamin A, folate and vitamins B6 and B12 all carry EU-authorised claims for contributing to the normal function of the immune system. They work best together as part of a varied diet, with supplements helping where intake is low.
What is the difference between vitamin C and zinc for immunity?
Both contribute to normal immune function, but in different ways. Vitamin C is a water-soluble antioxidant the body cannot store, so a regular daily intake is useful, and it also helps reduce tiredness. Zinc is a mineral involved in immune-cell activity and is often used for shorter, targeted reinforcement. Many people take them together.
Should I take vitamin D for immune support in Portugal?
Even in sunny Portugal, vitamin D levels commonly drop during autumn and winter, when sunlight is weaker and we spend more time indoors. Vitamin D contributes to the normal function of the immune system, which is why D3 — often paired with K2 — is one of the most popular choices in this collection during the colder months. If you are unsure about dosage, ask your doctor or pharmacist.
Can superfoods like spirulina and açaí help my immunity?
Superfoods such as spirulina, açaí and super greens are nutrient-dense whole foods rich in antioxidants, vitamins and minerals. They are not a cure, but as part of a balanced diet they add concentrated nutrition that supports overall wellbeing. They blend easily into smoothies, juices and breakfast bowls.
When is the best time to take immune supplements?
Fat-soluble vitamins such as vitamin D and omega-3 are best taken with a meal that contains some fat, which improves absorption. Vitamin C and zinc can be taken at any time of day. Consistency matters more than timing — a steady daily routine is what supports immune health over time.
Are these immune supplements suitable for vegans or children?
It varies by product. Many superfoods and plant-based formulas are vegan, while some softgels such as fish oil are not, and suitability for children also differs. Always check the label on each product page, and for children, pregnancy or breastfeeding, consult a healthcare professional first.
Is it safe to take immune supplements every day?
Food supplements are designed for daily use as part of a normal diet, provided you follow the recommended dose on the label and do not exceed it. They complement, rather than replace, a varied diet. If you take medication or have a health condition, check with your doctor or pharmacist before starting.
