How It Works
Why B1 matters when you eat less.
GLP-1 medications curb your appetite, so you eat a lot less. Eat less, and you take in less of everything, including vitamin B1.
B1 is water-soluble, so your body keeps only a small reserve. That is why a steady daily intake matters on the days you are barely hungry.
Not all B1 is the same.
Clear uses allithiamine, a fat-soluble form of B1 that crosses into cells more easily than the standard water-soluble form. Illustrative.

The Why
Why daily.
You eat less for as long as you are on your GLP-1. A daily foundation is the honest way to keep your basics covered that whole time.
You are doing the hard part. This is the simple daily base that goes with eating less.
