Выражение встречается в следующем контексте:
Purity, bioavailability and functionality of the protein are the essential criteria for a proper LF supplementation. Sourcing of milk from healthy dairy herds (federally certified as free from rinderpest, foot and mouth and mad cow diseases) for LF isolation sets the first gold standard. A proprietary process based on a non-thermal technology to prevent protein denaturization during the purification of LF from milk sets the second gold standard. Finally, a patent-pending technology to ensure highest purity, maximum bioavailability and optimum functionality for the LF protein sets the ultimate third gold standard. Based on a suggested average daily intake value, a daily dosage of sixty milligrams of LF for a month is 1.8 grams. Lactoferrin Gold 1.8™ - is sum of the above golden standards. никак не пойму при чем тут золотой стандарт
