His title states we are almost certainly wasting money buying vitamins.
Then he states: “There are some valuable vitamins and supplements that provide real health benefits.”
So, he really wants people to buy vitamins, just not as many?
He shouldn't have sensationalized the title as he did, then.
He made “click-bait.”
I say the point is to eat foods that contain the vitamins you need, rather than bottles and bottles of pills.
