Question about Brewers Yeast

Walking through baking goods aisle at my grocery store, I saw 'Brewers Yeast' on the shelf. So, I bought it!

It's a product by 'Gaylord Hauser', and it was $4.00.

The only time I've ever bought brewers yeast was at my supply store, which is about 20 miles from here... and closed today...

Anyway, has anybody used this product or any other 'brewers yeast' from the grocery store to brew with?

Thanks...

I don't think it is intended for brewing. It looks like something similar to nutritional yeast. Check it out:
