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。
Zinc is a trace mineral that plays a role in normal immune function and other everyday processes in the body.
Zinc supplements are available in several forms, including zinc picolinate, citrate, glycinate, oxide and sulfate. Product labels identify the specific form used.
Zinc picolinate is bound to picolinic acid, while zinc glycinate is bound to the amino acid glycine. Product labels identify the specific form used.
Chelated forms of zinc, such as picolinate, citrate and glycinate, are bound to an organic carrier, while non-chelated forms such as zinc oxide and zinc sulfate are not. Product labels identify the specific form used.
Zinc is often combined with vitamin C, vitamin D or magnesium in multi-ingredient formulas. Review the Supplement Facts panel to see what is included in a specific product.
