So I thought I was doing something helpful switching from my B complex to brewer's yeast a couple of months ago. It coincided with an attempt to take B1, which, although it initially boosted my energy, I never was able to take without negative effects. Around the same time my BP went up 15 - 20 points, just like that, which I connected with the B1, though I never was able to figure out why it would do that. @Gondwanaland posited that it might have boosted my thyroid, but I never was able to establish that connection. And my higher BP for the last 2 months remained a mystery to me.
And also, though I never made the connection until this week, I developed an extreme sensitivity to anything with MSG or its metabolites. e.g., before I could tolerate a can of chili for dinner and suddenly it gave me severe insomnia, as though I'd had a full meal at an Asian food restaurant.
And then 2 days ago I stumbled across an article about brewer's yeast and MSG, which stated there was no MSG in brewer's yeast, that the glutamic acid in brewer's yeast is "bound" and so was safe and could not affect one like MSG did. But I'd never even heard of any connection between brewer's yeast and MSG before, so did more reading, and found more denials of any MSG problem with brewer's yeast, but did find a youtube video of someone who said it (brewer's yeast) caused heart palpitations and I realized I had to just stop the brewer's yeast and see what happened.
And within 2 days my BP went back to my normal 125/75, after being in the 140's for 2 months. And last night I accidentally ate something that had some MSG but instead of being completely unmanageable and awake for half the night, it only affected me for an hour or two and I was able to sleep with lots of l-theanine and niacin.
So, despite all the protestations to the contrary, it's evident to me that brewer's yeast does have free glutamic acid which is an excitotoxin and damaging to the brain and can cause insomnia and all sorts of other problems.
Dang! and I thought I was eating one of the safest and most nutritious things in the world .....![Sluggish :sluggish: :sluggish:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
