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。

Consider the form of folate, dosage, serving size, product format and any additional ingredients. Review the Supplement Facts panel and product details to compare options.
Product labels identify the form of folate used, the amount per serving and any additional ingredients. Review the Supplement Facts panel and product details when comparing options.
