Also big brands with large facilities. I think they are decent.

The big issue is that supplements are not properly regulated. In the UK, they are considered food and regulated as such, and that doesn't provide any assurances. There is no requirement to do any testing. ConsumerLabs is a good service in theory, but having one batch that passed their independent testing 4 years ago doesn't mean what a brand is selling today still meets that standard. The brands with their own teams of chemists and in-house labs tend to be the better choices, and I'm certain both Now and Jarrow have these.
