Cutting Through the Haze of Health Supplements: A Rational View of Market Claims and Actual Effects
1. Current Status of Health Supplements and Consumer Attitudes
Health supplements, these seemingly mysterious products that have quietly entered many people’s lives, have now become a staple in numerous households. Whether it is one pill after a meal on the dining table, one capsule before bed on the nightstand, or even one tablet dropped into a glass of water while drinking, taking supplements has almost turned into a daily ritual. Some claim to feel more energetic after taking them; others assert that these products can cleanse blood vessels, protect the liver, lower blood pressure, blood sugar and cholesterol levels, and some even go so far as to claim that they can prevent cancer and slow down aging. These assertions are certainly appealing, but what is the truth behind them?
2. The Difference Between Health Supplements and Medicines
To be clear, health supplements are not medicines. Their original definition is "nutritional supplements", designed to provide essential nutrients for people whose dietary intake is insufficient. For instance, vitamins, minerals, and protein powders all play crucial roles in the human body. Deficiencies in these nutrients can lead to various discomforts—such as bone pain caused by vitamin D deficiency, or dizziness resulting from low iron levels. However, health supplements are not a panacea. They cannot cure diseases, let alone achieve the miraculous effects boasted in some promotions, such as "a cup of ganoderma powder cures all ailments".
3. Ingredients and Risks of Health Supplements
Today, the market is flooded with a dazzling array of health supplements with complex ingredient lists, like a colorful hodgepodge. On product labels, buzzwords such as "cordyceps", "bird’s nest", "fish oil", and "Coenzyme Q10" appear endlessly, with each ingredient seemingly touted as having magical effects. Yet, the reality is not always as advertised. For example, Omega-3 in fish oil has indeed shown potential benefits for heart health in some studies, but this is only true for those who are genuinely deficient in Omega-3. Unfortunately, many people blindly take large doses without knowing whether they lack this nutrient. This practice may not only be ineffective but also impose unnecessary burdens on organs like the kidneys.
In addition, the ingredient formulas of many health supplements are not transparent, making it difficult for consumers to access detailed product information. The dense English and Latin words printed on the bottles baffle the average person. When they try to look up details about the ingredients, they often find that information on some products is unavailable, or manufacturers refuse to disclose the specifics under the pretext of "patented formulas".
4. Misconceptions in the Health Supplement Market
This phenomenon is not unique to China; it is also prevalent overseas. Some organizations have conducted tests on a large number of health supplements and exposed that certain products do not actually contain the ingredients they claim to have. Worse still, some products are even found to be contaminated with heavy metals or prohibited drugs. The slogan "boosts immunity" seems to have become a mandatory label in health supplement advertisements, giving consumers a positive impression of these products.
However, immunity is not something that can never be too strong. An excessive immune response may trigger autoimmune diseases such as lupus erythematosus and rheumatoid arthritis. For people without confirmed immune deficiencies, relying solely on health supplements to boost immunity often yields insignificant results, and may even be counterproductive.
5. Notes for Middle-Aged and Elderly People
Some people regard health supplements as daily necessities, taking them once in the morning and once at night, as if this is the only way to guarantee good health. Nevertheless, long-term excessive intake of health supplements may pose risks—especially for middle-aged and elderly individuals with slower metabolism—such as increased gastrointestinal burden and damage to the liver and kidneys. In particular, supplements containing vitamin A can cause dizziness, hair loss, and bone pain when taken in excess; in severe cases, they may even impair liver function.
Besides, there are also popular antioxidant and anti-aging health supplements on the market, such as grape seed extract, lycopene, and astaxanthin. Although these sound sophisticated, excessive consumption also carries potential risks. Middle-aged and elderly people are the main consumer group of such products, but they need to be aware of the interactions between health supplements and medications to avoid health hazards.
6. Effectiveness and Misconceptions of Health Supplements
It is true that under laboratory conditions, these health supplements exhibit antioxidant properties. However, the human body is not a simple test tube. There remains considerable uncertainty as to whether these supplements can be effectively absorbed and exert their effects after ingestion. Currently, many related studies are still in the animal testing phase, which is significantly different from human trials.
Furthermore, the market is rife with supplements claiming to "enhance brain function" and "refresh the mind", targeting student and office worker groups who hope to improve their memory and relieve anxiety by taking these products. In reality, however, the key factors affecting attention and memory include sleep quality, diet, and emotional state. If one suffers from insufficient sleep, irregular diet, or emotional fluctuations, no amount of health supplements will be able to deliver their intended effects. It is like pouring good soup into a leaky pot—eventually, all the soup will seep away.
When talking about health supplements, we must pay attention to the middle-aged and elderly population. This group is often the loyal consumers of health supplements; many of these products are purchased by their children, who think that "they can’t hurt and might help a little". However, this mindset needs to be approached with caution.
