What is the result of too much yeast nutrient in the must?

Question

Hello, I screwed up and added a large excess of Fermaid K to my must. I have about 450L of must and I added about 300 grams of Fermaid K when I should have only added 112.5 grams (25 grams for 100L). I was not so worried I figured I just wasted some money until I saw a table that said a rate of 30 grams/ L of Fermaid K increases Thiamine above ATF levels. I have no clue what thiamine does to wine? Do you think I will have some kind of problem or do you think the yeast will sequester the extra nutrients?

According to my math, that'd make it 750mg/L approximately. Thiamine is vitamin B1, and my "Big 50" multi-B vitamin thing comes with 50mg which is 3333% the RDA. Which would mean the wine would have about

50K% the RDA. That's...really high.

But I suspect that the yeast will gobble up much of it, as yeast is loaded with B vitamins to begin with.

According to this web page:

23000 Thiamine is nontoxic. Being a water soluable vitamin, if you ingest too much, you should only end up with expensive, neon, yellow pee.

I'd try to avoid this mistake in the future, but in my non-expert opinion you'll probably be fine.
