They. Don't. Work.
None of them.
None. Of. Them.
So why does Health Canada license and allow the sale of 1,128 natural products whose listed purported use is for weight management? Or of the 671 products that purport they'll improve sexual enhancement? Or of pretty much any of them?
Maybe the answer lies somewhere in the taxation of the $1.8 billion annual Canadian sales of vitamins and supplements?
Maybe it lies in well-intentioned hope?
Maybe it lies is political contributions and lobbying?
But the one place where it doesn't lie is in science. Shouldn't that be the only place that matters?
