I have been taking the B-125 for many years and have great health at 89!
Still looking for B complex I can keep down :(
I love Swanson bitamins, but still haven't found what I'm looking for. If you don't have issues with the smell of B complexes this may be great for you, especially as they do have a nice potency. I tried these with high hopes, but they kept coming up all day. B complex vitamins can be really stinky, and smell/taste awful - especially when they 'talk back' later. Also these are really huge/hard to swallow - my bad, should have looked at the picture of the size; probably should have suspected they'd be huge as they are high potency, and being hard - just too hard to swallow. Or keep down. I've tried CoQ-10 in similar size, but were gel caps, so although not easy, they didn't hurt to swallow. So not about Swanson, just the size/type did not work for me, so I don't want to make the same mistake & order again.

Even though the B-Complex tablets are 'stinkier' than the capsules, I like this product for the added potency above the B-100 capsules. I don't mind the smell of B-Complex. The B-Complex Factors do so many good things, I take two of these tablets every morning. Works for me.
