When is a dietary supplement effective?
At certain times in life, stress, fatigue, illness, hormonal changes, or simply an unbalanced diet, our bodies may need extra support.
In Portugal, several studies show that the population has frequent deficiencies of vitamin D , magnesium , iron and even omega 3 , essential nutrients for energy, immunity and mental well-being.
A dietary supplement is not a substitute for a healthy diet , but it can be the ideal complement to help your body function at its best.
When formulated correctly, with safe and effective dosages, the supplement is capable of:
✅ Correct nutritional deficiencies
✅ Improve physical or emotional symptoms
✅ Support the normal functioning of the body
How to choose the right supplement?
The key is to identify products that are safe, effective, and tailored to your individual needs . Here are three things you should never ignore:
1. Purity of Ingredients
The cleaner the supplement, the better. Choose formulas that:
- No unnecessary additives (colors, artificial flavors, chemical sweeteners)
- Gluten and lactose free (unless they are important to the formulation)
- Tested to ensure no heavy metals, pesticides or contaminants
💚 At Naturvida , we only select brands that meet strict quality standards. Each product in our catalog is carefully selected to ensure you receive what is truly safe and effective.
2. Certifications and Quality
Not all supplements have the same level of guarantee. A good supplement:
- It has a complete and transparent label , with clear indication of dosages.
- It is produced in accordance with Good Manufacturing Practices (GMP)
- It has recognized certifications (ISO, HACCP, independent laboratory analysis)
- It's from a brand with history and credibility
💡 Tip: Choose supplements sold in specialized and reliable stores , such as Naturvida , where the products have already been curated by health professionals.
3️. Bioavailability: what the body actually absorbs
It's not enough to have the right ingredient, the body must be able to absorb it.
Prefer formulas that use nutrient forms with high bioavailability , for example:
- Magnesium bisglycinate (more absorbable than magnesium oxide)
- Iron bisglycinate (less aggressive to the stomach)
- Omega-3s from wild fish or algae with concentrated EPA/DHA
- Fat-soluble vitamins (A, D, E, K) accompanied by fat for better absorption
This is where many people get frustrated with low-quality supplements: they take them, but don't see results because absorption is minimal.
The importance of personalized monitoring
Even the best supplements need to be carefully chosen for you . Every person is unique: age, diet, routine, health history, and even medications currently being used influence nutritional needs.
💚 At Naturvida, we have partnered with a specialist in functional nutrition and integrative health who can help you identify the right supplement, in the right dose, for your goals.

In short
A good supplement is one that:
✅ It is pure and free of unnecessary additives
✅ It has clear certifications and labels , ensuring safety
✅ It is effective and bioavailable , so your body absorbs the maximum
And remember: supplementation should not be a “shot in the dark,” but rather a conscious strategy , carried out with the supervision of someone who understands health.
