I'm sorry, didn't mean to imply you made any disparaging remarks. It just struck a very familiar cord with me.
But I have to say I disagree with a number of points you made.
Chicken soup has recently been found useful for arthritis. Reason collagen.

They recently did a study on glandulars. To see if they really go to their specific glands. So they gave them isotopes to follow their path. Sure enough the thymus glandulars went to the thymus, the thyroid glandulars to the thyroid, so on and so forth. Doesn't seem unreasonable collagen does the same, since it has been showing benefits.
B12 can be taken sublingually. You don't need shots. In US no need for doc. You can get it on Amazon or anywhere. I agree though the digestive tract has trouble with it. And it gets worse with age.
And as far as big pharma don't be so naïve. They will do anything to keep the bucks rolling in. It is in their interest to have a sickly population so they can sell their expensive drugs. And will do anything to protect that. So any nutrients that would benefit our health are a danger to their pockets.
There is this emulsifier called carrageenan used in ice cream and other foods and supplements. Trump has just allowed this excipient to be used in organically labeled foods. But it has been known for decades to be a carcinogen. In fact, I first came across it, studying trials on colon cancer. (I'm a cancer survivor) They use it because it predictably induces cancerous tumors in lab rats so they can study anti-cancer treatments. But because a couple of studies that showed it was safe, they are allowing it, even with the decades of evidence to the contrary.
Here are the studies....

They look pretty convincing right? Well that is til you realize they were bought and paid for by a company called FMC Corporation. And who are they? Only the world's leading producer of carrageenan.
There are billions on the table. A couple of million for bogus trials is well worth it. Don't be naïve. You're a bright young man, with a bright future. I know you are part of the medical paradigm, but you also have choices in making informed decisions.
