Multivitamins, protein powder, calcium tablets, fish oil... Faced with such a wide variety of nutrients, it's easy to feel overwhelmed. Wang Xingguo, Director of the Nutrition Department at Dalian Central Hospital, told Life Times that these dietary supplements are also selective. Only when the right people make the correct choices can nutrients achieve their optimal effects.Multivitamins contain multiple vitamins and minerals, making them most suitable for four groups. First, those with irregular eating habits due to work or lifestyle. It's difficult for these individuals to obtain sufficient vitamins through diet alone. They should first aim to improve their eating habits; if that proves impossible, multivitamins can be used as a supplement. Second, pregnant women. While many pregnant women maintain a normal diet, the increased demand for nutrients during the second and third trimesters makes supplementation advisable under medical guidance.Third, the elderly. As organs decline with age, appropriate vitamin supplementation becomes essential. Fourth, children. Picky eating habits often lead to nutritional imbalances. Parents should first address dietary issues, but may supplement with multivitamins during periods of selective eating. Wang Xingguo explains that most multivitamin components are present at moderate levels. When taken as directed and from reputable sources, overdose is uncommon and generally safe.
Calcium supplements: Adolescents, menopausal women, pregnant women, and osteoporosis patients. Wang Xingguo advises: "To determine calcium deficiency, first assess dietary intake of dairy, soy products, and leafy greens. Adequate consumption of these three food groups generally eliminates calcium deficiency concerns. However, certain individuals require targeted supplementation due to specific health conditions."Adolescents in skeletal development require calcium supplementation. Beyond growth spurts, women need increased nutrition during mid-to-late pregnancy, while menopause often leads to calcium loss—all three stages warrant attention. Some osteoporosis patients with severe calcium deficiency may supplement under medical guidance. If daily milk intake falls below 500 grams, calcium tablets may be beneficial.Calcium supplement selection varies by individual. Those prone to constipation should opt for citrate calcium. Individuals with low stomach acid or poor digestion may choose organic calcium forms like lactate calcium or gluconate calcium, which dissolve well and cause less gastrointestinal irritation. Under identical conditions, calcium absorption rates are comparable across products, making calcium carbonate a cost-effective choice for most people.Generally, daily calcium intake below 2000 mg poses no significant side effects. Fish Oil: Recommended for pregnant women, breastfeeding mothers, and those with elevated blood lipids. Wang Xingguo notes that fish oil's rich polyunsaturated fatty acids may help control blood lipids and cholesterol, making it suitable for individuals with high lipid levels. Additionally, pregnant and breastfeeding women may take it under medical guidance.
Antioxidants like lycopene: No specific target group identified. Lycopene in tomatoes, grape seeds, and other foods possess antioxidant properties. Research indicates that consuming more tomatoes may protect prostate function in men. However, whether dietary supplements are necessary to achieve similar benefits should be discussed with a doctor or nutritionist.
Protein powder: For those unable to consume meat, eggs, or dairy. Healthy individuals typically obtain sufficient protein through diet and generally do not require supplementation. Individuals with poor digestion, trauma, or post-surgery should follow medical advice regarding specialized nutritional solutions. Elderly individuals who can only consume porridge and cannot eat meat, eggs, or dairy may take protein powder in moderation under medical guidance.
Finally, Wang Xingguo reminds everyone that balanced diets remain the simplest and most effective way to obtain nutrients. Supplements serve only as adjuncts—they cannot replace fresh foods, much less substitute for medications in treating illnesses. Patients with chronic conditions requiring long-term medication should avoid concurrently taking multiple supplements without consultation to prevent potential drug interactions.
