Hello, welcome to Show Me the Science with the Luke O'Neal and this week a request and as I've said I'm happy to take requests, I have a few lined up.
Trying to get through them and I'll I'll do it if I feel I can talk about it.
But this one is for Mary O'Donnell.
And Mary asked me to do a podcast on the science of vitamin supplements.
Now, obviously, this is a big one because people take lots of vitamin supplements, and is there evidence for them?
Do you need to take them?
What did they do?
There's lots of questions around vitamins, it must be said.
And as my first degree was biochemistry, a great old professor, he's passed away, sadly, John Scott was
Was an expert on vitamins, and he was especially expert on folic acid, which I'll come on to.
And he gave us lectures on vitamins.
So my knowledge of this goes all the way back.
To good old John when I was an undergrad, and uh it is a fascinating topic what these vitamins are.
They were discovered, oh, hundred years ago plus, I suppose, as key biochemicals to make sure you're healthy.
Many of them are used by enzymes, and enzymes are a very important part of the body, because enzymes do all kinds of things.
Some of them need vitamins to help them, and they were called vital amines because they had this amine structure on them and they were known to be vital.
Some of the research
Of course, was about deficiency.
And you would get a disease because you are getting uh a lack of a certain vitamin.
Uh, one great example was scurvy.
