B vitamins are unglamorous. They also happen to be nutrients people can run short of when appetite drops. Here is what they do, without the wellness-industrial hype.

What B vitamins do

B vitamins support normal energy metabolism and several other everyday functions. Daily Foundation includes B12, folate and B6 in their active forms.

Why it matters on a GLP-1

Two reasons. First, you are eating less, so you are getting less of every B-vitamin from food. Second, low B-vitamin status is one of the most-cited contributors to the fatigue, brain fog, and low mood that people report a few months into a GLP-1.

What is in Daily Foundation

  • B12 as methylcobalamin, 250 mcg.
  • Folate as L-5-MTHF, the active form, 400 mcg DFE.
  • Vitamin B6 as P-5-P, the active form, 1.7 mg.
  • The remaining four of the seven B vitamins: B1, B2, B3 (niacinamide, no flush) and B5.

Bottom line

If you are eating less, a B complex can help cover what a smaller diet may not consistently provide. That is why all seven are in every serving.
