*by D***3 on December 8, 2025*

We own a mobile IV company and this supplement is the closest I have found to being like IV B-complex in regards to my energy. I take a few vitamin supplements but this is the one I never miss. I take it first thing in the morning and it never upsets my stomach. Even when most other vitamins do. Great quality!
