常見問題 自2018年8月起, iHerb使用第三方廠商獨立實驗室ABC Testing、Eurofins 和 Alkemist 對產品進行測試。 使用第三方獨立實驗室，可確保結果客觀、沒有偏見。
iTested確認產品上提供的補充品成分表及/或營養成分表是正確的。 產品並會經過用於確認清潔標籤標準的測試，例如微生物化驗和重金屬化驗。
在所有iTested產品文件上都會列出測試方法。
產品每6個月進行一次測試。
No. Probiotic supplements vary in strains; some include a single strain, others combine multiple. Review the Supplement Facts panel and product details.
Lactobacillus and Bifidobacterium are two groups of probiotic microorganisms commonly used in supplements. Some products contain one group, others combine both.
Some probiotic strains require refrigeration to remain viable, while others are shelf-stable due to specialized encapsulation; always check the product label for storage instructions.
CFU (colony-forming unit) count, the specific strains included and storage requirements are important factors to compare. CFU count is just one factor to consider.
Probiotic supplements are available in capsules, tablets, gummies, powders, chewables and liquids. Product availability varies by brand.
