Supplements don't need to be taken daily; only take them when necessary; some supplements, when taken with medication, can very likely interfere with the drug's effectiveness; and even vitamins, which are safe, should not be taken in excess. Recently, the American magazine "Prevention" published an article outlining four rules for the safe use of supplements to guide everyone on proper consumption. Rule 1: Take them only when needed
The body's absorption of nutrients is not a one-size-fits-all process; consuming less can actually force cells to absorb them. Taking supplements every two to three days not only reduces the risk of overdose but also meets the body's demand for nutrients.
Chronic patients can moderately supplement B vitamins. Chronic illnesses are like a state of high stress, which can easily deplete B vitamins. For example, the elderly who have difficulty with chewing or food intake can moderately take multivitamins. Pregnant women and children should not randomly supplement with vitamins. As for whether to take folic acid to prevent neural tube defects in babies, it is recommended to discuss it with a doctor and pharmacist before use. Rule 2: Pay attention to drug interactions
Vitamins and health supplements often interact with Western medicine. It is recommended that people with heart, liver, or kidney problems discuss it with a doctor before use. Common drug interactions include the risk of bleeding when fish oil, garlic, ginkgo, and aspirin are taken together.
Fiber-based supplements, such as psyllium, can reduce the effectiveness of pain relievers like Panadol. Therefore, it is best to take the Western medicine first, and then take the supplement after two hours when the drug has been absorbed. Liver-protecting supplements, such as certain mushrooms, can activate the body's drug-metabolizing genes, rendering the medication ineffective. Therefore, it is best to wait 3-4 hours after taking Western medicine before taking such supplements. Rule 3: Do not exceed the recommended daily allowance
Even relatively safe water-soluble vitamins like B vitamins and Vitamin C can accumulate to excessive levels if urine output is low. For instance, too much Vitamin B6 can cause peripheral neuropathy, and too much Vitamin C can lead to kidney stones and headaches. Therefore, it is important to drink plenty of water when taking vitamins.
The intake of vitamins and minerals should ideally be within the recommended daily range, and choosing a multivitamin is safer than taking individual supplements. To identify if a vitamin dosage is excessive, you can check the Recommended Dietary Allowance (RDA) on the nutritional label. A USRDA label of 100% indicates it fully meets the requirement. If it is marked as 100% × 66, it means the recommended dose is 66 times higher, which is dangerous. Rule 4: Prefer smaller packaging
When taking supplements, it's also wise to diversify risks. It is best to switch to a different brand at least every two months, which not only increases the body's utilization rate but also helps prevent the development of resistance. Additionally, since the dosage is not large, it's best to choose smaller packaging.
