Successful
These drops have been a huge factor in assisting with needed energy and support daily while having success with losing weight as well. The taste isn't bad and I'd recommend them for daily support as a good complex vitamin "B"

Glad I added this to my regimen!
I can actually tell a difference in my energy and the way I feel in general! I never got it before with the diet drops and I can already tell a difference after just a couple days. Excited to see what happens these next 60 days!

Didn't feel energy boost and a bit of a headache after taking.
This liquid supplement is a deep red color. I placed the drops under my tongue 30 minutes before eating breakfast as recommended. The taste is a bit sweet and it is easy to take. Unfortunately, I do not feel energized but instead almost immediately developed a bit of a headache (which I rarely get). I like that it is made in the USA in a GMP facility and it is 3rd party tested. Unfortunately, I don't think this product is going to work for me. I will try it again tomorrow and update my review if anything is changed.

Bio Source program really works!
The vitamin B drops in conjunction with diet drops (and recommended diet) have helped me lose 6 pounds in one week! Program has taken away any feeling of being hungry!

Great taste
I purchased these vitamin B drops just hoping they wouldn't taste nasty. I have to admit I was pleasantly surprised when they tasted great. Once opened they need to be stored in the fridge. I do notice more energy now after taking them couple days. It doesn't make you jittery or shakey at all. I would definitely recommend these. I will definitely be reordering from this seller as well.
