Dietary Supplements: Benefits, Risks, and What You Should Know

What Are Dietary Supplements?

Dietary supplements are products designed to provide nutrients that may not be consumed in sufficient quantities through diet alone. They can include vitamins, minerals, amino acids, enzymes, herbs, probiotics, and other beneficial compounds in forms such as capsules, powders, liquids, or tablets.

In 2025, people turn to supplements not just for deficiency correction, but for energy, sleep, mood, digestion, immunity, and anti-aging support.

Risks and Considerations

While supplements can offer real benefits, inappropriate use can pose risks:

• Over-supplementation can lead to toxicity, particularly with fat-soluble vitamins (A, D, E, K) or iron.
• Interactions with medications may occur, especially with herbs like St. John’s Wort or ginseng.
• Poor-quality products may contain contaminants or incorrect dosages if not third-party tested.

What to Look for in a Quality Supplement

• Transparent labeling with ingredient amounts clearly listed
• Clinically backed dosages, not just marketing hype

• Minimal fillers and artificial additives
