Healing my schizophrenia

Posted by 5386587741773461120 on Sep 18, 2016

This product is fantastic, I've been on niacin I've been on niacin for 7 months, taking 2 pills 3 times a day and I'm getting better and better. I'm used to the flush I don't know why everyone makes such a big deal about it you get use to itand it gives a bit of placebo when you feel it working in your body. I just hope they continue making flush niacin because I love it!

Plain simple Niacin just works

Posted by 5641165882251819350 on Sep 05, 2016

This keeps my LDL cholesterol in check! Been using this for years and has no side affects apart from the flush which just shows it is working. Plain Niacin does not harm my kidneys at all according to my yearly blood check.

This supplement is way to high for Australian standards. My skin over my whole body broke out in red patches and my body was heating up and then shivering! The pharmacists said that it was way too high for Australian standards! Never take this again.

Now foods Niacin and my Schizophrenia

Posted by 4909661846532566807 on Aug 15, 2016

Dear IHerb, I am very happy to say because of your service of providing Now Niacin and Dr Abram Hoffers youtube videos on how to heal Schizophrenia, Bi-Polar, depression, alcohol abuse etc on the net I am almost healed of Schizophrenia! I am down to under half a tablet of the doctors prescription drug and taking 2 tablets of Niacin 3 times a day. I feel great, can think clearly, working harder like I did in my 20s before I got sick and very happy. Thanks be to my Mum for always believing in Natural Medicine, we call it Gods medicine. That unlike doctors drugs does NOT harm us. Thanks be to Bill Pinto for telling us about IHerb. Praise be to God for everything, He and His Son Jesus are so faithful and so much LOVE! I wish I had known about Niacin 20 years ago then I would not have lost 10 years of my life being in and out of hospital- what a waste of time that was. Soon I will be off the doctors drug completely. Many thanks IHerb, you are efficient, professional, truly a great company . God bless you all, Gabriella Napoli PS I now have family members and friends taking Niacin through IHerb and its a joy to hear their results.
