Dietary supplements, or Suplementos alimentos in Portuguese, are products designed to complement a person's diet by providing essential nutrients that may be lacking in daily meals. These supplements can include vitamins, minerals, proteins, amino acids, probiotics, and herbal extracts, all aimed at improving overall health and well-being.
Why Use Dietary Supplements?
Even with a balanced diet, some people may struggle to get all the nutrients they need due to busy lifestyles, dietary restrictions, or specific health conditions. Supplements help fill these gaps, providing essential benefits such as:
✔ Boosting immunity – Vitamins C, D, and Zinc help strengthen the immune system.
✔ Enhancing energy levels – B-complex vitamins and iron prevent fatigue and increase vitality.
✔ Supporting muscle growth and recovery – Proteins, amino acids (like BCAAs), and creatine are essential for athletes.
✔ Improving bone health – Calcium, vitamin D, and magnesium strengthen bones and prevent osteoporosis.
✔ Promoting digestive health – Probiotics and fiber supplements aid digestion and gut health.
