    Taking this for stress, along with Lysine and magnesium. Hard to tell what difference any one supplement makes on its own as I take many, but need all the help I can get.

    I am taking Health4All B3 (Niacinamide) in combination with Zinc, Copper and Folic acid (B9 again from Health4All) in a desperate trial to ease my Rosacea without the antibiotics intake. So far I am very happy with the result. From the order to the delivery (overseas) and the actual capsules, all great. Will be definitely back for more. Thank you Health4All!

    My Dermatology Consultant told me that I should take Nicotinamide 500mg capsules 3 times a day, so I have bought some. Health4All sells very reasonably priced products, which are excellent quality. I highly recommend them!

    This supplement was suggested by my dermatologist who says it may help reduce and prevent actinic keratosis. Too early to report results. Love the pack!

    Another vitamin that I like to add in addition to B Complex and B5 for chronic stress is B3. I find all the B vitamins help with it, but I like to boost it with these two.

    Greetings to all. Having read a report in Nexus magazine regarding niacinimide and arthritis I purchased niacinimide from Heath4 All initially on E Bay. They have the best price. I followed the article guidance and took 6 grams per day. I have not had any pain in my hands or hips since. I am 72. On seeing the results my wife took the same dose and has been free from arthritu
    s pain ever since. In excess of a year now. We take them every day with no side effects. Good luck to yourselves. David.
