Vitamins

Vitamins are essential micronutrients that the human body cannot synthesize in sufficient quantities, making it necessary to obtain them through diet or, when indicated, through supplementation. Each vitamin performs specific and documented physiological functions: vitamin D contributes to the normal absorption of calcium and the normal functioning of the immune system; vitamin C contributes to the protection of cells from oxidative stress; B complex vitamins contribute to normal energy metabolism and the normal functioning of the nervous system. The scientific evidence supporting these functions is recognized by the European regulation on nutrition and health claims.

At Viva Saudável, our vitamin collection is selected based on rigorous criteria of bioavailability, purity, and traceability. We prioritize active and highly absorbable forms — such as vitamin D3 instead of D2, or methylated forms of B vitamins — from certified suppliers.

FAQs

Vitamins are necessary for the normal functioning of multiple physiological processes, including energy metabolism, immune function, and bone health, among others. Supplementation may be considered in the context of an unbalanced diet, increased needs (such as pregnancy or aging), or documented deficiency. Prior evaluation by a healthcare professional is always recommended before starting any vitamin supplementation.

Fat-soluble vitamins (A, D, E, and K) accumulate in adipose tissue and the liver, so excessive amounts can be harmful in high doses. Water-soluble vitamins (C and B complex) are not stored in significant quantities, with any excess being excreted in the urine. This distinction is relevant for defining safe doses and supplementation frequency—which is why professional guidance is always recommended.

All supplements sold at Viva Saudável are sourced from suppliers who comply with European food safety standards, including the requirements of Directive 2002/46/EC on food supplements. We prioritize brands with recognized quality certifications (such as GMP — Good Manufacturing Practices) and third-party analyses that guarantee the absence of contaminants. The safety of our products is a non-negotiable priority.

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.
