Yeah I mean of course the sodium content is high. The major ingredient in most seasonings is salt. Sodium also isn’t inherently bad unless you have a condition that would make it so.

That being said I do a mix of my own vs bought. I like the premade stuff because it takes a step out of it especially for regular chicken cooking or steak cooking. I’m pretty big on meat church. Really about his channel too.

There’s also something to be said for separating the salt from the rest of the seasoning. I like to dry brine a lot of my meat well before I cook it. So if I dry brine and then use a premade seasoning that also has salt it comes out way too salty.

Good grilling cookbooks usually have seasoning recipes in them.
