Not sure who you are asking for brand name. I use the following supplement companies. Thorne, Life Extension, Qunol, and Puritan Pride.

I do shop around for sales and rewards so that influences me on which vendor I use. Qunol for example has some really good prices on Ubiquinol and Co-Q-10. Life Extension has really good magnesium and resveratrol. But I use Puritan Pride all the time which has a very expansive product line.

The only problem with Puritan Pride is in stock issues. I have researched the above companies for quality control and reported quality issues and all are listed as good. I say that with caveat that vitamin and supplement companies are not under FDA quality control or verification.
