Source Naturals, Advanced B-12 Complex is a great supplement for those looking for an effective and quality source of vitamin B12. I have been using this supplement for several months and have noticed an improvement in my overall health. I love that Source Naturals Advanced B-12 Complex provides multiple forms of vitamin B12 to maximize absorption and utilization by the body. In addition, the composition contains other B vitamins that help improve overall health and support the nervous system. TO

I have already taken this complex, and I am delighted with its reception, pleasant tasty, now I ordered my parents to raise b12 from them. after the full course, my body has significantly increased, I plan to take it regularly several times a year

It's important to not take b12 seperated. So this is a great complex to take. Taken regularly it really has an effect on my energy levels.

I have tried many forms of vitamin B12 complex and, in my view, this is the best. It contains all the forms of b12 one needs in safe forms (and doses).

B12 is a must have for people who are vegans. This vitamin usually is present in the meat, liver, fish, so if you are vegan, vitamin b12 might be lower, than usual.

Pleased that because of the high dose we now only need to remember to take it once a week! also covers all bases with both kinds of B12 since the research on which is best is inconclusive. It is sub-lingual which is good for absorbing but does mean it's slightly chalky in the mouth. Doesn't bother me but my daughter finds that annoying. Cant talk about efficacy as we've only just had this brand but I don't anticipate problems. UPDATE: WE all got good blood results for B12 after using this product so the efficacy was good for us.
