I ran out of the liposomal B that I usually have, so only had B complex tablets, which don't appear to get absorbed easily by me. My nerves were 'shot' and I was exhausted. Then I found this one in a pharmacy. After only 5 days of taking it my nervous system feels calm, I have bounce in my step and my son-in-law asked what I was on as he couldn't believe the difference in me! Its taste is nice too. Looking forward to it being back in stock, here.
