Recent data and medical observations show that more consumers are choosing specific dietary supplements, which has led to an increase in related health problems.

最近的數據與醫療觀察顯示，越來越多消費者選擇特定的膳食補充劑，這導致了相關健康問題的增加。

A study of over 63,000 U.S. adults, published in JAMA Network Open, shows that people are moving away from general multivitamins and toward single-nutrient or goal-oriented supplements. While multivitamins are still the most popular, there is a clear increase in the use of Vitamin D, Vitamin C, and other substances like collagen. This trend is strongest among adults aged 65 and older, where usage grew from 62% to 78% over twenty years. Experts emphasize that this shift is caused by a desire for personalized health and the influence of social media marketing.

一項發表在 JAMA Network Open、針對超過 63,000 名美國成年人的研究顯示，人們正從綜合維他命轉向單一營養素或目標導向的補充劑。雖然綜合維他命仍然最受歡迎，但維生素 D、維生素 C 以及膠原蛋白等物質的使用量明顯增加。這一趨勢在 65 歲及以上的成年人中最為顯著，使用率在 20 年間從 62% 增長到 78%。專家強調，這種轉變是由於對個性化健康的追求以及社交媒體營銷的影響。

At the same time, doctors report more health issues caused by these supplements. Clinical evidence suggests that taking too much of certain substances, such as Vitamin A or green tea extract, can cause liver damage. In fact, research indicates that 20% of liver injury cases in the U.S. are linked to herbal and dietary mixtures. Furthermore, high doses of supplements have been connected to the development of kidney stones and nerve damage. These risks are higher when people engage in 'supplement stacking,' which means taking multiple products that contain the same ingredients or interacting badly with prescription medicines without a doctor's advice.

與此同時，醫生報告了更多由這些補充劑引起的健康問題。臨床證據表明，攝取過多某些物質（如維生素 A 或綠茶萃取物）可能會導致肝臟損傷。事實上，研究指出美國 20% 的肝損傷病例與草本和膳食混合物有關。此外，高劑量的補充劑被認為與腎結石和神經損傷有關。當人們採取「補充劑疊加」時，風險更高，這意味著在沒有醫生建議的情況下，服用多款含有相同成分或與處方藥產生不良交互作用的產品。

Health organizations, including the National Institutes of Health, stress the importance of professional medical advice. They warn that consumers often wrongly assume that 'natural' products are always safe. While some doctors agree that supplements can help fix nutrient deficiencies caused by poor soil quality, they assert that these treatments must be based on scientific evidence and monitored to avoid damage to the stomach, kidneys, and liver.

包括美國國家衛生研究院在內的健康組織，強調了專業醫療建議的重要性。他們警告消費者經常錯誤地認為「天然」產品總是安全的。雖然一些醫生同意補充劑可以幫助解決因土壤品質不佳而導致的營養缺乏，但他們主張這些治療必須基於科學證據並受到監控，以避免對胃、腎臟和肝臟造成損害。

The current situation shows a growing preference for targeted supplements. However, without medical regulation, this trend creates a significant risk of organ toxicity.

目前的狀況顯示，人們對目標導向補充劑的偏好日益增加。然而，若缺乏醫療監管，這一趨勢將造成器官中毒的重大風險。
