A Very Satisfied Customer
I have used this product for at least 20 or more years.
I use it to control my hypoglycemia.
I take one a day, and make it a point to Never run out.
IF I fail to take it for 2-3 days, I can feel the hypo coming back.
I ONLY use the GNC brand, I got misdirected one time in ordering and got another brand and could tell right away, that it was NOT the same.
I really like the time release, it keeps me 'up and going all day'
It isn't the cheapest, But it is the best.
I would recommend it to anyone, with the same condition

This B Works!
It's always a very simple matter for me when I try a new vitamin - if I see positive results in 30-60 days then it's a keeper. Big B 150 does the trick. I would highly recommend this to anyone seeking a good dose of B!

Whole brown rice powder (Oryza sativa) is very allergenic
I don't take the 150 because of the Whole Brown Rice Powder (Oryza sativa) which is very allergenic. I have friends and family members who developed GERD after taking a GNC product that has this filler. The GERD went away after they stopped taking the product containing the Whole Brown Rice Powder (Oryza sativa). They put this filler in most of their B vitamins. Since people I know presented with GERD we tend to stay away from any GNC product that contains Whole Brown Rice Powder (Oryza sativa). I take the B complex 125 instead it doesn't have this filler and it's good for energy.

What color is the tablet?
A shopper on Mar 15, 2018
BEST ANSWER: a shade of terra cotta l(like a cross of a yellow ochre and light tan) it is not a primary color but more of an offshoot of a seconday mix.
can you crush the tablet...because it is too big to swallow?
Terri on Mar 7, 2018
BEST ANSWER: I find the capsules much easier to swallow. They come in 50 mg. But you can take more if you want the 150 mg's.
