I drink regular V8....wish they’d decrease the salt even more. Same with Campbell soup....too much salt...
Your body needs potassium, so a little of each per week, isn’t a bad thing. Living on them, would not be good.
I use Kosher coarse sea salt and grind it myself; same w/ Pink Hawaiian salt.

My father used to drink it. I tried it, and had to add the salt back it, along with hot sauce, pepper, horseradish, a celery stalk, and vodka.
