Highly effective but... beware of liver problems.

Posted by iHerb Customer on December 3 2016 | Verified Purchase

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.

Thanks for your feedback!

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

Thanks for your feedback!

뾰루지 발생

Posted by catcheritrye on October 20 2013 | Verified Purchase

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.

Thanks for your feedback!
