I get most of my vitamins from Swanson. The quality is good, and they usually have the best price.

My multi is a New Chapter I get from Amazon.
It's a 2 a day, but I only take one.

My Omega 3 is from algae and I get it from CVS. It's called Algol.

I get a 50/50 blend of (no fat) whey/heliogen casein from Protein Factory.
The price is good, and I can order it the way I want, no flavor, no sweetener, no junk.
