    I wanted to reduce my high Triglyceride ...

    I wanted to reduce my high Triglyceride levels. Niacin that causes flushing supposedly lowers, and prevents high Triglyceride levels in the body that cause a fatty liver. My Triglycerides have been high for decades even though my Cholesterol levels have stayed normal, but for how much longer is my question. I have not been diagnosed with a fatty liver by a doctor, but it is a good bet I have one, and a fatty liver can lead to future medical problems. I do not want to be sick as I age.

    B2 for skin

    of course there is no overnight reaction to taking vitamins so cannot rate or recommend this product. Skin doctor advised me to start taking B2 so I am doing so. The price on this product was the best I could find on internet and drug stores. These pills are large. I cut them in half to make easier to swallow.

  • Dermatologist recommended this product

    My dermatologist recommended I change from plain niacin to Niacinamie 500 mg twice a day. I looked it up and found it is best for skin. The niacinamide tablets were expiring 06/21/2021 but my nephew pharmacist said it still would still have good strength so I bought enough to last thru 2021 because the delivered price from this vender was much better than others.
