Supplement Purity Question

I no longer take OTC supplements at all.Consumer Reports had article few years ago about supplements,sent bunch different brands off to independent lab.Results were scary to me,some of them had all kinda stuff in them such as lead.Also standardization of doses was big issue.I remember tests they did on ginkgo biloba ,they bought 10 different brands and levels of ginkgo ranged from absolutely none to extremely large amounts.
My wife is nurse practitioner and recieves these monthly journals.A year or so ago one of them had article about supplements and it was very similar to what was found by Consumer Reports.They found all kind of adulterants that shouldn’t have been in them.
One of the supplements that sticks out in my mind was red rice yeast.Some people don’t want to take prescription statins, take rry instead since it is “natural”.Turns out active ingredient in rry is actually a statin,levels were all over the chart from very small amounts to dangerous amounts.According to article there have been documented cases of people suffering liver damage and liver failure from rry.
Bunch of these supplements are made in China which doesn’t inspire a lot of confidence in me.Sadly, lot of our prescription medicine ingredients are also made in China which pisses me off but at least the doses are standardized and purity is supposed to be checked. .Some years ago bunch of people were harmed by heparin that drug companies sourced from China.
I have argued with bunch of people that maintain that herbal supplements can’t hurt you since they are natural,there are lot of natural chemicals that can kill you-strychnine,cyanide,arsenic.A drug that was used for years was digoxin for heart failure,derived from purple foxglove plant.Very useful drug as long as dosage was monitored by lab blood levels but could be deadly in patients that overdosed on it,usually was people that took it,forgot and took another dose.Often it was elderly patients that weren’t competent enough to be taking medicine on their own.
Supplement people are going to be outraged but I feel strongly that any perceived benefits are placebo effect,which is very powerful.

Honestly creatine is the only really proven supplement. I don't consider protein or carb powders supplements, just food.

Never buy a proprietary blend.

I buy as much raw stuff as possible and dose myself. If you can find a fairly public company who does not use proprietary blends, that's your best shot, IMO.

No disrespect to 777, but I'm even skeptical about third party testing. It's easy to send pure stuff to the third party and cut your regular stuff with sawdust.

The threat of a lawsuit is the most effective deterrent.

Could you expound a little on that? What do you mean by raw stuff and what source? How do you dose?

Is there any hope of this improving the supplement industry? As things stand there's no explicit promise of medical benefit and without that there doesn't seem like an actual law with teeth to make the industry care if they are mixing chicken feathers with their tumeric or creatine
