I've been taking another brand's liposomal NAD for a few months and wasn't feeling all that much different. A friend of mine mentioned this company after seeing some info on social media so I decided to give it a shot before I gave up on oral NAD altogether. I'm only a week or so in and I already feel a difference in my energy level and mood. The taste is also MUCH better than the previous one I was using. I'm excited to see what improvements come with longer term use.

From the moment I started with this, I realized I had stumbled upon something special. Its daily impact on my life and overall "well" feeling is undeniable. I tried a few brands of capsules and those didn't come close!

Definite noticeable positive effects after about a week or 2 of taking this. Maybe not as immediate or extreme as the IV, but the trade off of not sitting there for 6 painful hours is enough to keep me satisfied!
