I really don’t want this to turn into the kind of place where we push products. But examine.com is really really awesome. They are without a doubt the best and most reliable unbiased resource for learning about supplements and vitamins and how they relate to the human body.
And in celebration of them turning 4 this year (they grow up so FAST!), they are having a sale. You can get any of their products for 40% off. And they are worth it. So you should consider doing that.
