What supplements should elderly people with poor immunity and prone to colds take?
Due to their weaker immunity, elderly individuals are prone to colds and may benefit from moderate supplementation with high-quality protein powder, multivitamins, deep-sea fish oil, tremella fungus, Chinese yam, and other health supplements for immune support. Specific details are as follows:

1. High-quality protein powder: Provides essential raw materials for building immune cells, enhances immune tissue function, and reduces the likelihood of viral infections. Products containing whey protein or plant-based proteins are recommended, as they are more easily absorbed and utilized by the body when consumed alongside regular meals.
2. Multivitamins: Contain various nutrients essential for maintaining immune function, helping to fill potential nutritional gaps in daily diets. They comprehensively support immune system operation and reduce the risk of infectious diseases such as colds.
3. Deep-sea fish oil: Rich in unsaturated fatty acids, it helps regulate metabolism and supports enhanced activity of immune cells, strengthening resistance against pathogens. It is suitable for elderly individuals to take in moderation as part of their daily routine.
4. Tremella fungus (silver ear): With a mild nature and sweet taste, it nourishes yin, moistens the lungs, strengthens qi, and benefits the stomach. It improves physical weakness in the elderly, indirectly boosting immunity and reducing colds caused by constitutional deficiencies.
5. Chinese yam: Possesses both dietary and tonic properties. It strengthens the spleen and nourishes the stomach, promotes nutrient absorption, and helps the body accumulate energy, thereby enhancing immunity at its root and reducing the frequency of colds.
In addition to taking supplements, elderly individuals should maintain regular sleep patterns, engage in gentle exercises such as walking, follow a balanced diet with proper mix of meat and vegetables, ensure adequate warmth, and avoid crowded places. A comprehensive approach like this will effectively strengthen their immune defenses.
