I would never buy supplement from a chinese company. But apparently, most supplements we buy in the US are manufactured in China and imported here for bottling.
This quote below from an article by NOW foods...
"Now, what does this mean for natural supplements and health ingredients? All ingredients from China are now suspect. In many cases our industry has no options but to purchase ingredients from China. The Chinese have cornered the commodities market for ingredients such as Vitamin C, the B vitamins, Stevia and xylitol. Although some of these ingreidents may be available from other countries, the vast majority in terms of tonnage, come from China. At NOW Foods, we have been aware of this, and have taken measures to control the quality and ensure the safety of these ingredients.
Our quality control procedures involve the setting of specifications and testing to these specifications for all ingredients, no matter where they come from, but especially from China. It’s our responsibility to ensure a safe supply of products to you. We take this responsibility for good design and testing seriously. We have invested huge amounts of money in a GMP facility and expensive testing capabilities. We audit our ingredient suppliers to ensure hygiene, quality and safety. We test for identity, purity and potency, and we look for contamination and adulteration, no matter where the ingreident comes from."
Part of the practices a GMP company follows is testing before they bottle. Good question is, do they just do that on first few batches, or every one?
