This is an excellent B-Complex that is well balanced. I like the fact that they use the Methyl form of B-12 and folic acid. As they explain in their literature, the methyl form is what the body uses and thus a more efficient way to supplement. Some people can't convert to the methyl form making most B-complexes ineffective. For someone who is healthy and just wants to make sure they are getting enough of the complex this is great. For someone with a specific health issue they can use this and supplement with isolated b vitamins like b3, B5, or a sublingual Methyl B12 to get the therapeutic dose they desire. Also, there is a 1 star review written by someone from Australia stating that Thorne uses GMO's in their products. I went on Thorne's website and they take a very strong policy stand against using GMO's. Below is a quote. "Thorne Research, Inc. does not make any products that contain Genetically Modified Organisms (known as GMOs)." They are also partnering with an anti GMO group. Below is another quote. "Thorne Research is partnering with the Non-GMO Project, a non-profit organization that verifies that products are free of GMOs or materials derived from GMOs. The Non-GMO Project has developed a nationally recognized standard that has been developed by industry partners who, like Thorne Research, share the concern about the long-term safety of GMOs." I have no interest in defending Thorne. They are big enough to defend themselves. I just don't like it when someone takes a shot at someone with un- true info.

As far as I can tell this product is highly effective. 2 weeks after I have stopped taking it, I got quite a nasty flu - so a drop in the immune system was there for sure. But those who have liver issues should be very careful. This is why I've stopped taking it in the first place. The Niacin dosage IMHO is too high and leads to liver problems. Just like this guy who used to drink 4 Red Bulls every single day and three months later ended up with liver failure. Due to the Niacin in the Red Bull as the investigation showed. In my case the daily usage of 1 capsule led to having my GGT liver values almost three times higher above the upper limit. After I've stopped taking it, the aforementioned value came back to normal.

Not too balanced - very high dosage of thiamine. Also, should have included pantothenic acid in its active form, pantethine.

면역력, 장건강에 좋다고 해서 구입했는데 (활성화된 B라고 해서 더 좋다는 말을 듣고) 얼굴에 뾰루지가 발생해서 복용 중단. 검색해보니 비타민B복합체를 복용후 뾰루지가 나는 경우가 있다고 함.
