Abstract

Caffeine-containing food supplements are often used as weight loss or memory enhancement support, which increases the potential risk for overdosing the compound. Whereas the presence of iodine-containing seaweed fucus in such products may result in thyroid disorders, when permanently overdosed. The study aimed to assess the content of caffeine and iodine in food supplements. Caffeine amount in tablets and capsules ranged from 91.8 to 138.9% of the declared content, and 2.6 ± 0.3 to 21.8 ± 2.8 mg/portion for the herbal blends with undeclared caffeine content. Iodine content ranged from 10.6 ± 0.4 to 52.5 ± 3.7 µg/portion of the products. Our results, although preliminary, suggest questionable usefulness of the tested preparations as weight loss support. Likewise, a simultaneous consumption of the recommended amounts with caffeine from other sources (e.g. coffee, tea, energy drinks, etc.), is unlikely to cause adverse effects.

含咖啡因和碘的食品补充剂的质量和安全评价

含咖啡因的食物补充剂通常被用作减肥或增强记忆力的支持，这增加了过量服用这种化合物的潜在风险。鉴于此类产品中含有含碘的墨角藻，如果长期过量服用，可能导致甲状腺疾病。这项研究旨在评估食品补充剂中咖啡因和碘的含量。片剂和胶囊中的咖啡因含量为申报含量的91.8 - 138.9%，未申报咖啡因含量的草药混合物为2.6±0.3 - 21.8±2.8 mg/份。碘含量为10.6±0.4 ~ 52.5±3.7µg/份。我们的结果，虽然是初步的，但表明测试制剂作为减肥支持的有用性值得怀疑。同样，如果同时摄入推荐量的咖啡因和其他来源的咖啡因(如咖啡、茶、能量饮料等)，也不太可能产生不良影响。
