it's well known that many if not most "supplements" arent worth the bottle they come packaged in.
I'm open about the fact that I sell supplements, but I believed in them
before I decided to make a career out of them.
I don't know where you get "it's well known that..." because, quite frankly, the supplements are the things that make food healthy (that is, a Vitamin C supplement IS Vitamin C, a CLA supplement IS CLA). The reason that the FDA doesn't regulate them, technically, is because they're recognized as "food" and not "drugs". (Not to mention that there's not as much money in it for them as designer drugs)
Taking a supplement that you already have enough of, or that you get from your diet, doesn't make sense. Why would you supplement something you have in sufficient amount? It's trying helping something that needs no help.
But there are lots of people who don't get all they need from food (poor eaters, vegetarians, people who don't like veggies/fruits), they have a particular condition (diabetes, aging, chronic obesity, ADHD), they are in a particular state of life (pregnancy, menopause, elderly) where the body's natural production of particular nutrients is stunted, or they are training very hard and need more of a particular nutrient to
supplement their training.
There are a lot of supplements whose health benefits aren't proven, but the
majority are supported by valid science. What do you really need to prove that some people need more Calcium, Vitamin D, Vitamin C, Iron, or Protein?
As far as herbal supplements, many studies have shown popular herbal supplements to be better than even pharmaceutical drugs. Look at St. John's Wort - a recent study showed it was more effective than the widely prescribed anti-depressant paroxetine. In the mid-90's, pharmaceutical companies tried to ban Red Yeast Rice because its natural chemical structure too closely mirrored their cholesterol reducing pharmaceutical drug.
Doctor's prescribe Glucosamine/Chondroitin/MSM for their patients with joint problems. They prescribe folic acid for pregnant women. They prescribe Vitamin D + Calcium for aging women. They prescribe iron for men deficient in it.
Experts in the FDA even recommend that all adults should take a multivitamin every day.
The list goes on and on. Most health professionals (I have relationships with a lot of them) take at least one supplement other than a multivitamin regularly, and many of them recommend them to their clients.
Anyhoo, aside from the overwhelming evidence in favor of supplementation, I'll just go back to my basic premise: supplements are nutrients. That's all you really need to know.
