I like both brands and use both. I have contacts at both companies that I call when I have questions about a product or dosing etc. At one time years ago when I was out of work at 61 due to job loss, I had gone to Jarrow plant here in LA thinking I'd like to work for them....I'd love to work for a supp company in some capacity, but it didn't work. I'd thought of working for a health food store, but I would "push" grape seed ex so much and they wouldn't like that...gotta "push" everything you can to customers....
