Consider taking appropriate drugs such as compounded vitamins + trace elements, soy phospholipids, hydrolyzed protein, lysine inositol vitamin B12, selenium yeast, etc. These can be involved in the synthesis/metabolism of certain enzymes, hormones, antibodies, protect cell membrane integrity, scavenge free radicals, restore normal physiological functions, and reflect immune enhancement. To improve the body’s immunity, it is generally unlikely to rely solely on taking a particular medication, but must be balanced nutrition, including supplementation with high-quality protein, fiber-containing staples, fruits and vegetables, appropriate physical exercise, adequate sleep and a happy mood. In particular, adequate sleep should be emphasized here, as staying up late or staying up too late for long periods of time can easily lower the body’s immunity. In addition, poor digestion and absorption in the gastrointestinal tract will affect the absorption of nutrients in the body, which will also lead to lower immunity.
