Hi, yeah I highly recommend Nutrilite as a great vitamin supply. I really got into the whole health thing about a year ago and really like the stuff Nutrilite offers. Some items have like more concentration, some less, there's a ton of variety to your liking. If you want, here's the link where I've been getting my supply.
I take a lot of supplements and have for a number of years. I like Wellness Resources, Life Extension and Beyond Health.Generally, I think you get what you pay for but do like some NSI Supplements from VitaCost and you cannot beat their prices.
